How to write the startup service script of CentOS Tomcat
CentOS Tomcat startup service script how to write, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.
1. Tomcat comes with jsvc. This tool starts 2 threads. If the application monopolizes the resources, it will cause the application to fail to start. This is the same as the daemon project in Apache Commons.
2. Java Service Wrapper
Referring to the script of nginx, I wrote a script for your reference:
The code is as follows:
#
#! / bin/bash
#
# chkconfig:-91 35
# description: Starts and stops tomcat
CATALINA_HOME=/data/site/tomcat-8085
PID_FILE=/var/run/tomcat8085.pid
JAVA_HOME=/usr/java/default
JAVA_OPTS= "- server-Xms512m-Xmx1024m"
CATALINA_BASE=$CATALINA_HOME
CATALINA_OPTS= "- Djava.library.path=$CATALINA_HOME/bin"
CLASSPATH=\
$JAVA_HOME/lib/tools.jar:\
$CATALINA_HOME/bin/commons-daemon.jar:\
$CATALINA_HOME/bin/bootstrap.jar
RETVAL=0
# Source function library.
. / etc/rc.d/init.d/functions
# Source networking configuration.
. / etc/sysconfig/network
# Check that networking is up.
[${NETWORKING} = "no"] & & exit 0
# Start daemons functions.
Start () {
#
# Start Tomcat
#
If [- e $PID_FILE]; then
Echo "$PID_FILE already running...."
Exit 1
Fi
Echo-n $"Starting $PID_FILE:"
Nohup $JAVA_HOME/bin/java\
-Dcatalina.home=$CATALINA_HOME\
-Dcatalina.base=$CATALINA_BASE\
-Djava.io.tmpdir=$TMP_DIR\
$CATALINA_OPTS\
-cp $CLASSPATH\
$JAVA_OPTS\
Org.apache.catalina.startup.Bootstrap start > $CATALINA_HOME/logs/catalina.out &
RETVAL=$?
Echo
[$RETVAL = 0] & & touch $PID_FILE
Return $RETVAL
}
# Stop daemons functions.
Stop () {
#
# Stop Tomcat
#
Echo-n $"Stopping $PID_FILE:"
Nohup $JAVA_HOME/bin/java\
-Dcatalina.home=$CATALINA_HOME\
-Dcatalina.base=$CATALINA_BASE\
-Djava.io.tmpdir=$TMP_DIR\
$CATALINA_OPTS\
-cp $CLASSPATH\
Org.apache.catalina.startup.Bootstrap stop > $CATALINA_HOME/logs/catalina.out &
RETVAL=$?
Echo
[$RETVAL = 0] & & rm-f $PID_FILE
Return $RETVAL
}
# See how we were called.
Case "$1" in
