CentOS配置Tomcat开机启动

通常我们进行服务器维护的时候需要注意点为，服务器上的容器一般都是开机启动，减少停机后应用还需要一个一个启动的麻烦。

1) 新建tomcat文件

touch /etc/rc.d/init.d/tomcat

2) 编辑文件，将下面代码复制到tomcat文件中，不过需要自己修改对应的JDK路径和Tomcat的CATALINA_HOME的路径

#!/bin/sh
# chkconfig: 345 99 10
# description: Auto-starts tomcat
# /etc/init.d/tomcatd
# Tomcat auto-start
# Source function library.
#. /etc/init.d/functions
# source networking configuration.
#. /etc/sysconfig/network
RETVAL=0
# export JAVA_HOME=/usr/java/jdk1.7.0_60
# export JRE_HOME=/usr/java/jdk1.7.0_60/jre
export CATALINA_HOME=/apps/apache-tomcat-8.0.32
export CATALINA_BASE=/apps/apache-tomcat-8.0.32
start()
{
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
$CATALINA_HOME/bin/startup.sh
RETVAL=$?
echo " OK"
return $RETVAL
fi
}
stop()
{
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
$CATALINA_HOME/bin/shutdown.sh
RETVAL=$?
sleep 1
ps -fwwu root | grep tomcat|grep -v grep | grep -v PID | awk '{print $2}'|xargs kill -9
echo " OK"
# [ $RETVAL -eq 0 ] && rm -f /var/lock/...
return $RETVAL
fi
}

case "$1" in
start)
start
;;
stop)
stop
;;

restart)
echo $"Restaring Tomcat"
$0 stop
sleep 1
$0 start
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
;;
esac
exit $RETVAL

3) 设置tomcat脚本权限

chmod 755 /etc/rc.d/init.d/tomcat

4) 设置脚本开机启动

chkconfig --add tomcat

5) 完成配置，重启服务

reboot

6) 验证是否启动

ps -aux | grep tomcat
或
ps -ef | grep tomcat
