How to kill tomcat server process using Mac Terminal Command


Sometimes you may not be able to start the Apache Tomcat App Server if it has not stopped properly. In such cases, one has to kill its process. If you are on Mac OS X system or any other Unix server then to do this,

  1. Open Terminal,
  2. Type command :ps -ef |grep -i 'catalina'
  3. When you run this command you should get an output like,
  4. localhost:~ code2care$ ps -ef |grep -i 'catalina' 501 1144 623 0 6:59PM ?? 0:22.98 
    /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java -
    Dcatalina.base=/Users/code2care/Setups/apache-tomcat-7.0.61 -Dcatalina.home=/Users/code2care/Setups/apache-
    tomcat-7.0.61 -Dwtp.deploy=/Users/code2care/Setups/apache-tomcat-7.0.61/wtpwebapps -
    Djava.endorsed.dirs=/Users/code2care/Setups/apache-tomcat-7.0.61/endorsed -Dfile.encoding=MacRoman -classpath 
    /Users/code2care/Setups/apache-tomcat-7.0.61/bin/bootstrap.jar:/Users/code2care/Setups/apache-tomcat-
    7.0.61/bin/tomcat-juli.jar:/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/lib/tools.jar 
    org.apache.catalina.startup.Bootstrap start
    
    501 1262 1103 0 8:35PM ttys000 0:00.00 grep -i catalina
    
    localhost:~ code2care$

    Here 501 is the process id for the tomcat server in my case.

  5. Now run the kill command to stop this process: kill <process-id> (ex: kill 501)
  6. Now try to start the server, it should load without any error!
