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.
1. 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
2. set up certificates:
2a: get the mitca at http://ca.mit.edu/mitClient.crt and save it as
/usr/local/ssl/certs/mitClient.crt
2b: 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
2c: 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
2d: 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). Also, some servers, such
as Thalia servers, can represent an entire subdomain. These servers
will need certificates issued with a wildcard in the domain name, such
as *.isda-thalia-1.mit.edu.
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).
2db. 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
2e:When you receive a certificate from MIT Certificates, save it as /usr/local/ssl/certs/`hostname`-cert.pem
2f: 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
3 set up apache-ssl
3a: download Apache 2.2.4 from apache archive site at
http://archive.apache.org/dist/httpd/
3b: 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
3c. compile apache following the instruction in the INSTALL file.
To enable the SSL, do the following:
./configure --prefix=/home/apache --enable-ssl \
--with-ssl=/usr/local/ssl \
--enable-modules="most mod_rewrite"
make
make install
4. set up mod-jk
4a. 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
4b. build and install binaries according to BUILD.txt. apxs is at
/home/apache/bin/apxs. mod_jk.so will be put at /home/apache/modules
cd native ./configure --with-apxs=/home/apache/bin/apxs --enable-ssl make make install
5. install jdk 1.6 which is required by tomcat 5.5.25
5a. download jdk 1.6 binary at http://java.sun.com/javase/downloads/index.jsp
5b. You may need to set the binary file to be executable:
chmod u+x,u-w jdk-6-linux-i586.bin
5c. 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
5d. 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
6. install tomcat
6a. download apache-tomcat-5.5.25.tar.gz from: http://tomcat.apache.org/download-55.cgi
6b. unzip and untar (gunzip , tar -xvf) into your working directory, such as /home
cd /home tar -xzvf /root/apache-tomcat-5.5.25.tar.gz cd apache-tomcat-5.5.25
8. Do the configuration:
8a. Tomcat part: cd into the tomcat home directory
cd /home/apache-tomcat-5.5.25
8aa. enter the conf directory and create a jk directory
cd conf mkdir jk cd jk
8ab. copy the workers.properties file from /opt/tomcat-connectors-1.2.21-src/conf and put it in conf/jk
cp /opt/tomcat-connectors-1.2.21-src/conf/workers.properties /home/apache-tomcat-5.5.25/conf/jk
8ac. make certain the following directives in workers.properties are set:
workers.tomcat_home=/home/apache-tomcat-5.5.25 workers.java_home=/usr/local/jdk1.6.0 ps=/ worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13 worker.ajp13.lbfactor=1 worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers= ajp13
8aa. enter the conf directory and create a jk directory
after
<Server port="8005" shutdown="SHUTDOWN">
add
<Listener className="org.apache.jk.config.ApacheConfig"
modJk="/home/apache/modules/mod_jk.so" jkDebug="info"
workersConfig="/home/apache-tomcat-5.5.25/conf/jk/workers.properties"
jkLog="/home/apache-tomcat-5.5.25/logs/mod_jk.log"/>
after
<Engine name="Catalina" defaultHost="localhost">
add
<Listener className="org.apache.jk.config.ApacheConfig" append="true" />
8ae. If this is going to be a Web Services servers, disable direct
connections to tomcat and force communications to go through apache,
by commenting out the port 8080 connector block in server.xml:
<\!-\-
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
\-->
If this is going to be a Thalia server, skip this step.
8af. 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.
8ag. Run the java_home.sh script and start tomcat
source /etc/profile.d/java_home.sh /home/apache-tomcat-5.5.25/bin/startup.sh
8ah. Tomcat creates a mod_jk.conf file in conf/auto directory the 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/apache/modules/mod_jk.so"
8b. apache side: edit /home/apache/conf/httpd.conf
edit the following directives:
ServerRoot "/home/apache" # change to apache home directory User apache # change from daemon Group apache # change from daemon Include conf/extra/httpd-vhosts.conf # Uncomment Include conf/extra/httpd-ssl.conf # Uncomment
8c. add to /home/apache/conf/httpd.conf, near the end of the file,
above the 'Include conf/extra/httpd-ssl.conf' directive:
<IfModule \!mod_rewrite.c> LoadModule rewrite_module modules/mod_rewrite.so </IfModule> <IfModule \!mod_jk.c> LoadModule jk_module "/home/apache/modules/mod_jk.so" </IfModule> JkWorkersFile "/home/apache-tomcat-5.5.25/conf/jk/workers.properties" JkLogFile "/home/apache-tomcat-5.5.25/logs/mod_jk.log" JkLogLevel info
8d. edit /home/apache/conf/extra/httpd-vhosts.conf to have ONLY one of the
following VirtualHost blocks:
8d1. 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>
8d2. Web Services:
<VirtualHost \*:80> RedirectPermanent [https://isda-ws2.mit.edu/] </VirtualHost>
8e. edit /home/apache/conf/extra/httpd-ssl.conf and alter the following
directives:
# points to directory for static html files DocumentRoot "/home/apache/htdocs" # the servername of the server ServerName isda-ws2.mit.edu:443 # the admins of this server ServerAdmin dracus@mit.edu,dongq@mit.edu,dtanner@mit.edu # error log file ErrorLog /home/apache/logs/error_log # access log file TransferLog /home/apache/logs/access_log # public server certificate SSLCertificateFile /usr/local/ssl/certs/isda-ws2.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
8f. add the following after the '<Directory "/home/apache/cgi-bin">'
block in /home/apache/conf/extras/httpd-ssl.conf
SSLOptions \+StdEnvVars \+ExportCertData
8g. add the following at the end of /home/apache/conf/extra/httpd-ssl.conf:
JKMount / ajp13 JKMount /* ajp13 JkMount /manager ajp13 JkMount /manager/* ajp13 JkMount /uaws ajp13 JkMount /uaws/* ajp13 JkMount /webdav ajp13 JkMount /webdav/* ajp13 JkMount /geows ajp13 JkMount /geows/* ajp13 JkMount /servlets-examples ajp13 JkMount /servlets-examples/* ajp13 JkMount /tomcat-docs ajp13 JkMount /tomcat-docs/* ajp13 JkMount /host-manager ajp13 JkMount /host-manager/* ajp13 JkMount /jsp-examples ajp13 JkMount /jsp-examples/* ajp13 JkMount /balancer ajp13 JkMount /balancer/* ajp13 JkMount /mitidws ajp13 JkMount /mitidws/* ajp13
9. 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
10. copy the following files to the noted locations. They should be bundled
with this document:
MitIdService.jar moves to:
/home/apache-tomcat-5.5.25/shared/lib
rolesApplicationContext.xml moves to:
/home/apache-tomcat-5.5.25/shared/classes
rootauth moves to
/root
11. install the web init script into /etc/init.d, and place starter links into
the /etc/rc.d/ runlevel directories. It should be bundled with this
document.
11a. edit the variables in the top section of the web file to use the
directories and binaries correct for this system
11b. be certain to check if apache is using a httpdctl or apachectl starter
program, usually contained in /home/apache/bin, and set the apachectl
variable accordingly
11c. set web to be executable
chmod a+rx,a-w /etc/init.d/web
11d. 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/rc2.d/K15web ln \-s /etc/init.d/web /etc/rc.d/rc3.d/K15web ln \-s /etc/init.d/web /etc/rc.d/rc4.d/K15web ln \-s /etc/init.d/web /etc/rc.d/rc5.d/K15web ln \-s /etc/init.d/web /etc/rc.d/rc6.d/K15web ln \-s /etc/init.d/web /etc/rc.d/rc2.d/S15web ln \-s /etc/init.d/web /etc/rc.d/rc3.d/S15web ln \-s /etc/init.d/web /etc/rc.d/rc4.d/S15web ln \-s /etc/init.d/web /etc/rc.d/rc5.d/S15web
12. Add line to /var/spool/cron/root to cause rootauth to run every 15 min, and
freshen the Kerberos tickets.
cat >> /var/spool/cron/root 0,15,30,45 * * * * /root/rootauth \^C
13. 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
14. 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.
14a. 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/apache-tomcat-5.5.25 cp \-a geows\* mapws\* mitidws\* uaws\* testcert\* TestRemoteAlfresco\* /home/apache-tomcat-5.5.25/webapps/
to see the applications deployed on a server 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
14b. Move the /home/https/weblib directory into /home
mv /home/https/weblib/ /home/weblib ln \-s /home/weblib /home/https/weblib
Alternatively, if there is not /home/https/weblib, create a /home/weblib directory
mkdir /home/weblib
14c. Edit /etc/init.d/web to have the following global variable:
export LD_LIBRARY_PATH=/usr/lib:/home/weblib
14d. Restart web services and tomcat
/etc/init.d/web restart
15. Install an AFS client, or check that a client is installed.
15a. 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 /
15b. 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
15c. 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.
15d. Go to the OpenAFS client binary directory and execute the setup 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.
patch /root/mit-openafs-package.patch cd /opt/mit-openafs-setup/bin ./setup
16. Install version of moira that uses Kerberos 5
16a. 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
17. 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
