linux(centos7)设置tomcat开机启动

1、在/etc/rc.d/rc.local中加入:

#java environment 
export JAVA_HOME=/usr/java/jdk1.8.0_161
export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
export PATH=$PATH:${JAVA_HOME}/bin
/home/tomcat/apache-tomcat-8.5.29/bin/startup.sh

2、更改rc.local的权限

因为如果是centos7的话，默认是系统自动不执行/etc/rc.d/rc.local，需要更改权限

#!/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 constrast 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.

#这个文件是为了兼容性的问题而添加的。

#强烈建议创建自己的systemd服务或
