Following commands get Tomcat
1 2 | sudo apt-get updatesudo apt-get install tomcat7 |
While installing I was being asked
1 2 3 | Creating config file /etc/logrotate.d/tomcat7 with new version * no JDK or JRE found - please set JAVA_HOMEinvoke-rc.d: initscript tomcat7, action "start" failed. |
I tried run this command to prepare JAVA_HOME, then I got this message:
1 | $ vim ~/.bashrc |
Now I need to install “vim” by following error message:
“The program ‘vim’ can be found in the following packages…”
1 | sudo apt-get install vim |
After installing vim, open the file, and go to the last line by press ‘G’ key, then press ‘i’ to be edit mode, and add following, then press ‘esc’ key to exit the edit mode, then save it and close it by type ‘:wq’
1 2 3 4 | JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")export JAVA_HOMEPATH=$PATH:$JAVA_HOME/binexport PATH |
Check the result:
1 2 3 4 5 6 | $ echo $JAVA_HOME/usr/lib/jvm/java-8-oracle$ echo $PATH/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/java-8-oracle/bin$ readlink -f /usr/bin/javac/usr/lib/jvm/java-8-oracle/bin/javac |
Run this command to edit tomcat config file
1 | sudo nano /etc/default/tomcat7 |
OR for Lubuntu
1 | sudo leafpad /etc/default/tomcat7 |
I replaced “JAVA_HOME” and “JAVA_OPTS”
1 2 | JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom -Djava.awt.headless=true -Xmx512m -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC"JAVA_HOME=/usr/lib/jvm/java-8-oracle |
Run tomcat:
1 | sudo service tomcat7 restart |
Then go this http://127.0.0.1:8080. It worked!
1 | sudo apt-get install tomcat7-docs tomcat7-admin tomcat7-examples |
Some additional installation.
Check the tomcat installed:
1 2 | $ whereis tomcat7tomcat7: /etc/tomcat7 /usr/share/tomcat7 |
Need to give permissions for Tomcat:
1 2 3 4 5 6 7 8 | cd /usr/share/tomcat7sudo ln -s /var/lib/tomcat7/conf confsudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policysudo ln -s /var/log/tomcat7 logsudo chmod -R 777 /usr/share/tomcat7/confsudo ln -s /var/lib/tomcat7/common commonsudo ln -s /var/lib/tomcat7/server serversudo ln -s /var/lib/tomcat7/shared shared |
Adding the Tomcat as eclipse server:
Window -> Pereferemces -> Server -> Runtime Environments -> Add
Enter the Tomcat installed directory and specify the JRE, then hit “Finish”
Tomcat had been added as a eclipse server.
To disable autostart for a service
1 | sudo update-rc.d tomcat7 disable |
To open config file:
1 | nobu@HP15z:/etc/init.d$ sudo leafpad tomcat7 |
Tomcat can be started manually via eclipse server
