How do I kill this tomcat process in Terminal?

Using ps -ef | grep tomcat I found a tomcat server that is running. I tried kill -9 {id} but it returns "No such process." What am I doing wrong?

Here's an example:

Admins-MacBook-Pro:test-parent tom.maxwell$ ps -ef | grep tomcat
2043706342 39707 39695   0  3:40PM ttys000    0:00.00 grep tomcat
Admins-MacBook-Pro:test-parent tom.maxwell$ kill -9 39707
-bash: kill: (39707) - No such process

There is no need to know Tomcat's pid (process ID) to kill it. You can use the following command to kill Tomcat:

pkill -9 -f tomcat

> ps -ef | grep tomcat | awk '{print $2}' | xargs kill -9

Part 1

> ps -ef | grep tomcat => Get all processes with tomcat grep

Part 2

Once we have process details, we pipe it into the part 2 of the script

> awk '{print $2}' | xargs kill -9 => Get the second column [Process id] and kill them with -9 option

Hope this helps.

Tomcat is not running. Your search is showing you the grep process, which is searching for tomcat. Of course, by the time you see that output, grep is no longer running, so the pid is no longer valid.

just type the below command in terminal

ps -ef |grep 'catalina'

copy the value of process id then type the following command and paste process id

 kill -9 processid

As others already noted, you have seen the grep process. If you want to restrict the output to tomcat itself, you have two alternatives

• wrap the first searched character in a character class

    ps -ef | grep '[t]omcat'
  

This searches for tomcat too, but misses the grep [t]omcat entry, because it isn't matched by [t]omcat.

• use a custom output format with ps

    ps -e -o pid,comm | grep tomcat
  

This shows only the pid and the name of the process without the process arguments. So, grep is listed as grep and not as grep tomcat.

ps -Af | grep "tomcat" | grep -v grep | awk '{print$2}' | xargs kill -9

In tomcat/bin/catalina.sh

add the following line after just after the comment section ends:

CATALINA_PID=someFile.txt

then, to kill a running instance of Tomcat, you can use:

kill -9 `cat someFile.txt`

ps -ef

will list all your currently running processes

| grep tomcat

will pass the output to grep and look for instances of tomcat. Since the grep is a process itself, it is returned from your command. However, your output shows no processes of Tomcat running.

This worked for me:

Step 1 : echo ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'

This above command return "process_id"

Step 2: kill -9 process_id
// This process_id same as Step 1: output

this works very well (find tomcat processes and kill them forcibly)

ps -ef | grep tomcat | awk '{print $2}' | xargs kill -9

I had to terminate activeMQ java process among many java processes on the server, and this one is started by the specific user (username is activemq). So good way of separating may be to start a process by a specific user :

ps -ef | grep "activemq" | awk '{print $2}' | xargs kill -9

as @Aurand to said, tomcat is not running. you can use the

ps -ef |grep java | grep tomcat command to ignore the ps programs.

worked for me in the shell scripte files.

kill -9 $(ps -ef | grep 8084 | awk 'NR==2{print $2}')

NR is for the number of records in the input file. awk can find or replaces text

To kill a process by name I use the following

ps aux | grep "search-term" | grep -v grep | tr -s " " | cut -d " " -f 2 | xargs kill -9

The tr -s " " | cut -d " " -f 2 is same as awk '{print $2}'. tr supressess the tab spaces into single space and cut is provided with <SPACE> as the delimiter and the second column is requested. The second column in the ps aux output is the process id.

For mac users,

This is the only solution working for me.

sudo kill -9 `sudo lsof -t -i:8080`

Note: replace 8080 with your port number
