Linux系统下tomcat服务自动重启

1.修改系统启动时脚本文件

vi /etc/rc.d/rc.local

#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
export JAVA_HOME=/home/jdk1.8.0_231
/home/apache-tomcat-8.5.68/bin/shutdown.sh
/home/apache-tomcat-8.5.68/bin/startup.sh

   注意：脚本可能报错找不到java环境，所以加上export JAVA_HOME=/home/jdk1.8.0_231，另外tomcat需要先关闭再启动，不然进程一直存在导致启动失败

2.检查rc.local服务是否启动

 systemctl list-unit-files|grep rc.local
 # static表示已开启
 # disable未开启 如果没开启执行下面命令
 systemctl start rc.local.service

3.给文件授权

chmod +x /etc/rc.d/rc.local

4.关闭tomcat，手动执行脚本，看是否启动

sudo /etc/rc.d/rc.local

5.服务器重启测试

reboot
