INCOMPLETE -- Apache, SSL, SASH Server Install Instructions for Thalia, Web Services, etc

Note: Next revision cycle, start building everything into
$HOME/[app]-[version#] and creating a symlink to $HOME/[app] so that there is
no question about what the current, in use, directory is.

Note: When downloading software to install in these instructions, always
download the source code, and avoid binary installers. Binary installers tend
to make inaccurate assumptions about what libraries you have installed on your
system, as well as other problems.

download openssl 0.9.8a source from http://www.openssl.org/source/. follow the instruction in the INSTALL document, compile and install the binaries. the default location is /usr/local/ssl. If you want to change it, run config like this:
```
cd /opt
tar -xzvf /root/openssl-0.9.8a.tar.gz
cd openssl-0.9.8a
./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl
make
make install
```

set up certificates:

get the mitca at http://ca.mit.edu/mitClient.crt and save it as /usr/local/ssl/certs/mitClient.crt

convert mitCA.crt to pem format:

openssl x509 -in /usr/local/ssl/certs/mitClient.crt -inform DER -outform \
    PEM -out /usr/local/ssl/certs/mitCA.pem

Generate rsa key

This simply generates some random stuff:

ps > /tmp/foo
ps -elf >> /tmp/foo
cd /usr/local/ssl/bin
./openssl genrsa -rand /tmp/foo 1024 >/usr/local/ssl/private/`hostname`-key.pem

Generate request for a certificate

cd /usr/local/ssl/bin
./openssl req -key /usr/local/ssl/private/`hostname`-key.pem -new \
   >../certs/`hostname`-req.pem

##*send the file /usr/local/ssl/certs/`hostname`-req.pem to mitcert@mit.edu,

Please be aware, the organization (O) is:
Massachusetts Institute of Technology
and the common name (CN) is the name of the server or
service, including the domain name (.mit.edu).&nbsp; Also, some servers, such
as Thalia servers, can represent an entire subdomain.&nbsp; These servers
will need certificates issued with a wildcard in the domain name, such
as \*.isda-thalia-1.mit.edu. &nbsp;

Remember, if the server is a Thalia server, if will need a wildcard
certificate and DNS record for \*.\[hostname\], and if it is doing any type of
authentication, it will need a joint client/server certificate to be able
to connect to the Shibboleth server (and have end users connect to it as
well).

To generate a self signed temporary certificate, add the x509 and nodes options to the openssl command line.

cd /usr/local/ssl/bin
./openssl req -key /usr/local/ssl/private/`hostname`-key.pem -new \
     -x509 -nodes >../certs/`hostname`-temp.cert

When you receive a certificate from MIT Certificates, save it as /usr/local/ssl/certs/`hostname`-cert.pem

Commands to view cert information:

to look at a request:
```
openssl req -in ./req.pem -text
```

to look at the private key:

openssl rsa -in /usr/local/ssl/private/`hostname`-key.pem -text

to look at the server certificate:

openssl x509 -in /usr/localx/ssl/certs/`hostname`-cert.pem -text

Setup local directory structure and users.

Setup the www user.

groupadd www
useradd -g www -d /home/www -m -r -s /bin/bash www

Set the www user directory structure and copy the config files into place.

mkdir /home/www/weblib
mkdir /home/www/etc
cp -a /root/weblib /home/www/weblib
scp -r root@trogdor.mit.edu:${REPOS_HOME}/System-configs/www-user/etc /home/www/etc
cp /root/map-dev-ws1-new-keytab /home/www/etc/krb/daemon.map-dev-ws1.krb5.keytab
chown -R www:www /home/www/etc
chmod a-w,o-rx,u+r /home/www/etc/krb/daemon.map-dev-ws1.krb5.keytab

Make certain that the library files are put into their correct locations.

scp -R  root@trogdor.mit.edu:${REPOS_HOME}/System-configs/www-user/weblib /home/www/weblib/

If needed (if this system is going to hold an Alfresco instance, or something similar), setup the repository user.
```
groupadd repos
useradd -g dbusr -d /home/www -m -r -s /bin/bash repos
```

If needed, setup the database user.

groupadd dbuser
useradd -g dbusr -d /home/www -m -r -s /bin/bash dbusr

set up apache-ssl
1. download Apache 2.2.4 from apache archive site at http://archive.apache.org/dist/httpd/
2. Unpack apache 2.2.4 (tar -xzvf) and do "cd httpd-2.2.4"
```
cd /opt
tar -xzvf /root/httpd-2.2.4.tar.gz
cd httpd-2.2.4
```
3. compile apache following the instruction in the INSTALL file. To enable the SSL, do the following:
```
./configure --prefix=/home/www/apache-2.2.4 --enable-ssl \
  --with-ssl=/usr/local/ssl \
  --enable-modules="most mod_rewrite"
make
make install
ln -s /home/www/apache-2.2.4 /home/www/apache
```
set up mod-jk
1. download mod-jk 1.2.21 source (previous versions have a security hole that could allow a remote attacker to execute arbitary code) from http://tomcat.apache.org/connectors-doc/.
```
cd /opt
tar -xzvf /root/tomcat-connectors-1.2.21-src.tar.gz
cd tomcat-connectors-1.2.21-src
```
2. build and install binaries according to BUILD.txt. apxs is at /home/www/apache/bin/apxs. mod_jk.so will be put at /home/www/apache/modules
```
cd native
./configure --with-apxs=/home/www/apache/bin/apxs --enable-ssl
make
make install
```
install jdk 1.6 which is required by tomcat 5.5.25
1. download jdk 1.6 binary at http://java.sun.com/javase/downloads/index.jsp
2. You may need to set the binary file to be executable:
```
chmod u+x,u-w jdk-6-linux-i586.bin
```
3. execute the binary installer as root. If it produces a rpm file, use rpm -ivh to install it. If you downloaded the straight binary installer, move to a directory with installed software, such as /usr/local. Also, you will need to page through a licensing agreement and type yes to accept it.
```
cd /usr/local
/root/jdk-6-linux-i586.bin
```
  - or
    ./jdk-6-linux-i586-rpm.bin rpm -ivh jdk-6-linux-i586
4. create a file in /etc/profile.d named java_home.sh. It should contain a line exporting a variable pointing to the Java home directory. Then make this file world executable.:
```
cat > /etc/profile.d/java_home.sh
export JAVA_HOME=/usr/local/jdk1.6.0
^C
chmod a+xr,a-w /etc/profile.d/java_home.sh
```
install the SASH Server NOTE: These instructions are written assuming version 2.0.4-BETA of the SASH Server, but this version is not officially supported. We are waiting on version 2.0.4 to become officially supported.
1. If this is a server ops installed and managed RHEL 4 VM, request that they install the 32 bit NPTL threading libraries, and reboot the VM. If this is a RHEL 5 VM, check the the threading libraries are 32 bit compatible. If this is a physical server, this step can be skipped.
2. download sash-server-2.0.4-BETA.tar.gz from: https://portal.sourcelabs.com/?module=download You will need to register and login to the web site to be able to download the SASH Server. Also, copy the sashsrv.conf mkInstance, modify-instance-file.sh and mit-worker-consolidater.sh out of the ISDA repository and onto the machine.
3. unzip and untar (gunzip , tar -xvf) into your working directory, such as /home
```
cd /home/www
tar -xzvf /root/sash-server-2.0.4-BETA.tar.gz
ln -s sash-server-2.0.4-BETA sash-server
cd sash-server-2.0.4-BETA
```
4. Edit /etc/profile.d/sash_home.sh to export a home variable, and set it world executable.
```
cat > /etc/profile.d/sash_home.sh
export SASHSRV_HOME=/home/www.sash-server-2.0.4-BETA
export LD_LIBRARY_PATH=/usr/lib:/home/www/weblib
^c
chmod a-w,a+rx /etc/profile.d/sash_home.sh
source /etc/profile.d/sash_home.sh
```
5. Copy the modify instance file and the MIT worker consolidator file into the SASH server bin directory.
```
cp /root/mkInstance $SASHSRV_HOME/bin
cp /root/modify-instance-file.sh $SASHSRV_HOME/bin
cp /root/mit-worker-consolidater.sh $SASHSRV_HOME/bin
chmod ug+rx,a-w $SASHSRV_HOME/bin/modify-instance-file.sh $SASHSRV_HOME/bin/mit-worker-consolidater.sh $SASHSRV_HOME/bin/mkInstance
```
6. Copy the sash-2.0-flattened-jars.zip file onto the server and update the commons-io jar file.
```
cd ${SASHSRV_HOME}/core/server/webapps/manager/WEB-INF/lib
unzip -j /root/sash-2.0-flattened-jars.zip  sash-2.0-flattened-jars/commons-io-1.3.1-1.jar
```

Do the configuration:

SASH Server part: cd into the tomcat home directory
```
cd $SASHSRV_HOME/conf/template
```
1. enter the conf directory and create a jk directory
```
cd conf
mkdir jk
cd jk
```
2. copy the workers.properties file from /opt/tomcat-connectors-1.2.21-src/conf and put it in conf/jk. Also copy the sashsrv.conf template into the template conf directory.
```
cp /opt/tomcat-connectors-1.2.21-src/conf/workers.properties \
   $SASHSRV_HOME/conf/template/conf/jk
cp /root/sashsrv.conf /home/www/sash-server-2.0.4-BETA/conf/template/conf
```
3. make certain the following directives in workers.properties are set:
```
workers.tomcat_home=%%CATALINA_BASE%%
workers.java_home=/usr/local/jdk1.6.0
ps=/
worker.list=ajp13
worker.ajp13.port=%%AJP_PORT%%
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers= ajp13
```
  - comment out the ajp12 lines in workers.properties.
4. edit conf/server.xml and add the following:
  - after <Server port="%%SHUTDOWN_PORT%%" shutdown="SHUTDOWN"> add
    <Listener className="org.apache.jk.config.ApacheConfig" modJk="/home/www/apache/modules/mod_jk.so" jkDebug="info" workersConfig="%%CATALINA_BASE%%/conf/jk/workers.properties" jkLog="%%CATALINA_BASE%%/logs/mod_jk.log"/>
  - after <Engine name="Catalina" defaultHost="localhost"> add
    <Listener className="org.apache.jk.config.ApacheConfig" append="true" />
5. If this is going to be a Web Services servers, disable direct connections to the SASH Server and force communications to go through apache, by commenting out the http port connector block in server.xml:
```

```
  - If this is going to be a Thalia server, skip this step.
6. Uncomment the AJP block in server.xml.
```

    <Connector port="%%AJP_PORT%%"
        protocol="AJP/1.3" />
```
7. edit tomcat_users.xml, and add the following user definition just above the '</tomcat-users>' line:
```
<role rolename="manager"/>
       <user username="tomcat" password="*****" roles="tomcat,manager"/>
```
  - be certain to change the password to be the password for the team the server is providing services to. Check with your groups manager to see what the password standards for your group are. Do not cut and paste this password into place, do not use "*****" as a password, etc.
8. Edit the sashsrv.conf file and add the base port information for JMX. Add it near the bottom, between the AJP base port and the max port range.
```
cd $SASHSRV_HOME/conf
vi sashsrv.conf

# The base port for the JMX handlers - MIT addition
#
JMX_BASE=9000
```
9. Add the JAVA_HOME location to $SASHSRV_HOME/conf/sashsrv.conf. Also change the ACTIVE_PROBE_PLAN and LD_LIBRARY_PATH to have $SASH_HOME in their paths. The conf file is read by the startup script, so putting the variables in will not work. They must be fully qualified. Also add recursion to LD_LIBRARY_PATH.
```
LD_LIBRARY_PATH=/home/www/sash-server-2.0.4-BETA/lib:${LD_LIBRARY_PATH}
```
10. Update the www user.
```
chown -R www:www /home/www
```
  - And edit $SASHSRV_HOME/bin/setvars, $SASHSRV_HOME/bin/sash-server.init, and $SASHSRV_HOME/bin/sash-server-CS2.init, and change the SASHSRV_USER.
    sed -i s:SASHSRV_USER=\"sashsrv\":SASHSRV_USER=\"www\":g $SASHSRV_HOME/bin/setvars sed -i s:SASHSRV_USER=\"sashsrv\":SASHSRV_USER=\"www\":g $SASHSRV_HOME/bin/sash-server.init sed -i s:SASHSRV_USER=\"sashsrv\":SASHSRV_USER=\"www\":g $SASHSRV_HOME/bin/sash-server-CS2.init
11. To progate the changes made to the config, delete the default server container, and create a new one.
```
cd $SASHSRV_HOME/servers
rm -rf default
cd $SASHSRV_HOME/bin
./mkInstance -N default
cd $SASHSRV_HOME/servers/default
```
  - Also create any other server containers that may be needed. Some of the common ones are mitid, roles, moira, sis, and misc.
12. Set up the additional directories and files needed for JMX and the standard ISDA/MAP configuration scripts.
```
cd /home/www
mkdir /home/www/etc
mkdir /home/www/krb /home/www/containers
mkdir /home/www/etc/jmx
touch /home/www/etc/jmx/jmxremote.password
chmod a-wx,u+r,go-r /home/www/etc/jmx/jmxremote.password
chown -R www:www /home/www
```
13. Run the java_home.sh script and start the SASH Server
```
source /etc/profile.d/java_home.sh
$SASHSRV_HOME/bin/sashctl all start
```
14. Tomcat creates a mod_jk.conf file in ./core/conf/auto/ directorythe first time is runs. Correct it to point to where mod_jk.so resides.
  - change
    LoadModule jk_module "/usr/local/apache/libexec/mod_jk.so"
  - to
    LoadModule jk_module "/home/www/apache/modules/mod_jk.so"

Apache side:

edit /home/www/apache/conf/httpd.conf

edit the following directives:

ServerRoot "/home/www/apache"          # change to apache home directory
User www                               # change from daemon
Group www                              # change from daemon
Include conf/extra/httpd-vhosts.conf   # Uncomment
Include conf/extra/httpd-ssl.conf      # Uncomment

add to /home/www/apache/conf/httpd.conf, and the bottom of the other includes:

# SASH Server/mod_jk includes
Include /home/www/sash-server-2.0.4-BETA/core/conf/auto/mod_jk.conf

<IfModule \!mod_rewrite.c>
    LoadModule rewrite_module "/home/www/apache/modules/mod_rewrite.so"
</IfModule>

edit /home/www/apache/conf/extra/httpd-vhosts.conf to have ONLY one of the following VirtualHost blocks:

Thalia:

NameVirtualHost \*:80

<VirtualHost *:80>
     ServerName \*.isda-thalia2.mit.edu

     RewriteEngine On

     RewriteCond %{HTTP_HOST}    !^isda-thalia2\.mit\.edu [NC]
     RewriteCond %{HTTP_HOST}    !^test\.isda-thalia2\.mit\.edu [NC]
     RewriteCond %{HTTP_HOST}    !^demo\.isda-thalia2\.mit\.edu [NC]
     RewriteCond %{HTTP_HOST}    !^hst\.isda-thalia2\.mit\.edu [NC]
     RewriteCond %{HTTP_HOST}    !^ap\.isda-thalia2\.mit\.edu [NC]
     RewriteRule \^/(.*)         [http://isda-thalia2.mit.edu/$1] [L,R]
</VirtualHost></pre></code>

Web Services - edit for correct server name:

<VirtualHost \*:80>
     RewriteEngine On

     RewriteRule \^/(.*)         [https://finniganfen.mit.edu/$1] [L,R]

</VirtualHost>

To prevent some web applications (such as WarehouseServices) from being redirected to https, add an escape clause between "RewriteEngine On" and the RewriteRule:
```
RewriteCond %{REQUEST_URI}       !/WarehouseService
```

edit /home/www/apache/conf/extra/httpd-ssl.conf and alter the following directives:

# points to directory with tomcat servers
DocumentRoot "/home/www/sash-server-2.0.4-BETA/servers/"
# the servername of the server
ServerName gybe.mit.edu:443
# the admins of this server
ServerAdmin dracus@mit.edu,dongq@mit.edu,dtanner@mit.edu
# error log file
ErrorLog /home/www/apache/logs/error_log
# access log file
TransferLog /home/www/apache/logs/access_log
# public server certificate
SSLCertificateFile /usr/local/ssl/certs/gybe.mit.edu.pem
# private server certificate
SSLCertificateKeyFile /usr/local/ssl/private/https-key.pem
#certificate path
SSLCACertificatePath /usr/local/ssl/certs
# certificate authority key
SSLCACertificateFile /usr/local/ssl/certs/mitCA.pem

SSLVerifyClient require
SSLVerifyDepth 10

add the following after the '<Directory "/home/www/apache/cgi-bin">' block in /home/www/apache/conf/extras/httpd-ssl.conf
```
SSLOptions +StdEnvVars +ExportCertData
```
to pass environment variables from apache to tomcat, add the following to the end of httpd.conf (note, the name for those environment variables might change between different apache versions. Apache comes with a cgi script in cgi-bin/printenv. Run this script in your https enabled browser to verify that these variables still holds).
```
JkEnvVar SSL_CLIENT_DN nodefault
JkEnvVar SSL_CLIENT_S_DN_CN nodefault
JkEnvVar SSL_CLIENT_S_DN_Email nodefault
JkEnvVar SSL_CLIENT_S_DN nodefault
JkEnvVar HTTP_ACCEPT_LANGUAGE nodefault
JkEnvVar SSL_CLIENT_CERT none
```

copy the following files to the noted locations. They should be in the ISDA software repository.
1. MitIdService.jar moves to $SASHSRV_HOME/core/shared/lib
```
cp /root/MitIdService.jar $SASHSRV_HOME/core/shared/lib
```
2. rolesApplicationContext.xml moves to $SASHSRV_HOME/core/shared/classes
```
cp /root/rolesApplicationContext.xml $SASHSRV_HOME/core/shared/classes/
```

install the web init script into /etc/init.d, and place starter links into the /etc/rc.d/ runlevel directories. It is in the Software Repository on Trogdor.

edit the variables in the top section of the web file to use the directories and binaries correct for this system
be certain to check if apache is using a httpdctl or apachectl starter program, usually contained in /home/www/apache/bin, and set the apachectl variable accordingly
set web to be executable
```
chmod a+rx,a-w /etc/init.d/web
```

link startweb and stopweb to the web program, from wherever it is located, and link start scripts in /etc/init.d:

ln -s /etc/init.d/web /root/startweb
ln -s /etc/init.d/web /root/stopweb
ln -s /etc/init.d/web /etc/rc.d/rc1.d/K15web

ln -s /etc/init.d/web /etc/rc.d/rc4.d/S15web
ln -s /etc/init.d/web /etc/rc.d/rc5.d/S15web

Copy the SASH Server init file into /etc/init.d

cp $SASHSRV_HOME/bin/sash-server.init /etc/init.d/sash-server
chmod a+rx,a-w /etc/init.d/sash-server

Link the SASH Server init file to runlevels.

ln -s /etc/init.d/sash-server /etc/rc.d/rc1.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc2.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc3.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc4.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc5.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc6.d/K16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc2.d/S16web

ln -s /etc/init.d/sash-server /etc/rc.d/rc4.d/S16web
ln -s /etc/init.d/sash-server /etc/rc.d/rc5.d/S16web

Edit /etc/init.d/sash-server and correct the value of SASHSRV_HOME.

update paths in /etc/profile, by adding the following line in the path manipulation code block (you can find it by searching for /usr/local/sbin)
```
pathmunge /usr/local/bin
      pathmunge /usr/kerberos/bin
```
If this is an upgrade on a server that had previously had a tomcat on it, there are additional steps to move necessay files and code to the new directories.
1. copy the webapps from the old deploy of tomcat to the new one. Be certain to restart the server if it was running previously.
```
cd /home/www/sash-server-2.0.4-BETA/servers/$SERVER/webapps
cp -a geows\* mapws\* mitidws\* uaws\* testcert\* TestRemoteAlfresco\* \
     /home/www/sash-server-2.0.4-BETA/servers/$SERVER/webapps
```
  - to see the applications deployed in a container that are not part of the default tomcat install, get a listing of the directory:
    ls -1 --hide=balancer --hide ROOT --hide=jsp-examples \ --hide=servlets-examples --hide=tomcat-docs --hide=webdav
2. Move the /home/https/weblib directory into /home/www
```
mv /home/https/weblib/ /home/www/weblib
ln -s /home/www/weblib /home/https/weblib
```
  - Alternatively, if there is not /home/https/weblib, create a /home/www/weblib directory
    mkdir /home/www/weblib
3. Edit /etc/init.d/web to have the following global variable:
```
export LD_LIBRARY_PATH=/usr/lib:/home/www/weblib
```
4. Copy the libMitIdNativeClient.so into /home/www/weblib
```
cp /root/libMitIdNativeClient.so /home/www/weblib
```
5. Restart web services and tomcat
```
/etc/init.d/web restart
```
Set up kerberos daemon principle and service ACLs for the system.
1. Send email to accounts@mit.edu and ask for a kerberos principle in the format of daemon.[hostname].krb5.keytab. When you receive it, install it in /home/www/etc/krb as daemon.[hostname].krb5.keytab.
2. Send email to Mark Silis or Jim Repa and request that the kerberos principle above (daemon/[hostname].mit.edu@ATHENA.MIT.EDU) be added to the access control list for the databases on Illinois that the web service will be using (often mitid or roles).
If this is a Web Services system, install an AFS client, or check that a client is installed. Thalia systems do not need this.
1. Check if an AFS client is installed by looking at the root directory. If a client is installed, the afs directory will be near the top.
```
ls -l /
```
2. If an AFS client is not installed, download these packages from the MIT Athena or Thalia software lockers:
```
mit-openafs-setup-1.2-3.noarch.rpm
mit-krb-config-1.0-3.noarch.rpm
mit-openafs-package.patch
```
  - Unless the server is a virtual server. If this is the case, email server ops to have the virtualized AFS kernel module installed.
3. Use rpm to install these packages, installing the Kerberos configuration package first.
```
rpm -ivh mit-krb-config-1.0-3.noarch.rpm
rpm -ivh mit-openafs-setup-1.2-3.noarch.rpm
```
  - Please note: There are no paths in these commands. Store them in a conveinent install directory, and cd to it first.
4. Go to the OpenAFS client binary directory and execute the setup script. It will ask if you want the AFS client to be started at boot time. Type yes.
```
cd /opt/mit-openafs-setup/bin
./setup
```
  - If system is a SMP (multiprocessor) machine, apply the SMP patch before compiling.
    cd /opt/mit-openafs-setup/bin patch < /root/mit-openafs-package.patch ./setup
If this is a Web Services system, install version of moira that uses Kerberos 5. Thalia systems do not need this.
1. upload moira-rhel4-clients.tar.gz onto the server, and untar to /usr/local
```
cd /usr/local
tar -xzvf /root/moira-rhel4-clients.tar.gz
```
To start and stop tomcat and apache, use the initialization scripts in /etc/init.d. Be certain to leave them running when you are finished.
- starting
```
/etc/init.d/web start
```
- stopping
```
/etc/init.d/web stop
```
