Centos 7 设置开机自启tomcat

#第一步首先要提前安装好tomcat 然后在/usr/lib/systemd/system目录下添加tomcat8.service 命令如下：
vi /usr/lib/systemd/system/tomcat8.service

#第二步在里面输入：
[Unit]

Environment='JAVA_HOME=/data/server/jdk1.8'
Environment='CATALINA_PID=/data/server/tomcat8/bin/tomcat.pid'
Environment='CATALINA_HOME=/data/server/tomcat8/'
Environment='CATALINA_BASE=/data/server/tomcat8/'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'

WorkingDirectory=/data/server/tomcat8/

ExecStart=/data/server/tomcat8/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID

#第三步来配置tomcat 开机启动输入：
