pgrep only search for the process name without the full path (in your case only java) and without arguments.
pgrep 只搜索没有完整路径的进程名称（在你的情况下只有java）并且没有参数。
Since tomcat-5.5-26-rumis part of the latter, i'd search the pid with
由于tomcat-5.5-26-rum是后者的一部分，我会用
ps -ef | grep tomcat-5.5-26-rum | grep java | awk ' { print } '
The double grep is useful to discard the grep pids itself
双 grep 可用于丢弃 grep pid 本身

Just add following line at the start of catalina.shfile
只需在catalina.sh文件开头添加以下行
CATALINA_PID="$CATALINA_BASE"/logs/tomcat.pid
OR
或者
CATALINA_PID=/tmp/tomcat.pid
And bounce tomcat. This will create a tomcat.pidfile in the given path and put the Tomcat process pid in it.
和反弹tomcat。这将tomcat.pid在给定路径中创建一个文件，并将 Tomcat 进程 pid 放入其中。

This worked for me:
这对我有用：
This will give the process id of current running tomcat
这将给出当前正在运行的 tomcat 的进程 ID
echo ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'
回声 ps aux | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{ print $2 }'
