101: Tomcat

sudo apt-get install tomcat7

Setup Environment

Open up global profile:

sudo nano /etc/profile

Add this to global profile:

export CATALINA_HOME##/usr/share/tomcat7
export CATALINA_BASE##/var/lib/tomcat7

Add a symlink to lib folder in CATALINA_BASE

For some reason, Tomcat does not add a link to the $CATALINA_HOME/lib folder in $CATALINA_BASE. So lets add this for our convenience, nothing more.

sudo ln -s /usr/share/tomcat7/lib /var/lib/tomcat7/lib

Install APR (Apache Portable Runtime):

sudo apt-get install libapr1 libaprutil1 libapr1-dev libssl-dev make

Install Tomcat Native

Grab the latest version from http://tomcat.apache.org/download-native.cgi

Then wget it on your server and untar it.

cd jni/native

sudo ./configure --with-apr##/usr/bin/apr-1-config --with-java-home##$JAVA_HOME --with-ssl##yes --prefix##$CATALINA_HOME
sudo make && make install

You might need to do all the above as root user (and not just plain sudo).

Check that libtcnative* are now in /usr/share/tomcat7/lib

Then, open up your setenv.sh file:

sudo nano $CATALINA_HOME/bin/setenv.sh

and add the lines:

LD_LIBRARY_PATH##$LD_LIBRARY_PATH:$CATALINA_HOME/lib
export LD_LIBRARY_PATH

chmod the file:

chmod 751 setenv.sh

You will also need to allow the tomcat user access to the SSL files. This is done by adding the tomcat user to the ssl-cert group:

sudo usermod -a -G ssl-cert tomcat7

Also just double check the permissions on your private key are as follows:

sudo chown root:ssl-cert /etc/ssl/private/official-ssl.key
sudo chmod 640 /etc/ssl/private/official-ssl.key

Setup Config file

Open up the server.xml file:

sudo nano /var/lib/tomcat7/conf/server.xml

Open up a port 8080 (http-alt) connector, and an SSL port 9090 connector. Open up these ports on your firewall.
