tomcat设置开机自启（centos）设置tomcat开机自动启动是原来WEB项目中常见的工作需求，技多不压身，需要的

1.编辑tomcat.service，插入脚本

   # vi /etc/systemd/system/tomcat.service

--脚本如下：
[Unit]
Description=Tomcat80
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=oneshot
ExecStart=/usr/local/tomcat/apache-tomcat-8.5.56/bin/startup.sh
ExecStop=/usr/local/tomcat/apache-tomcat-8.5.56/bin/shutdown.sh
ExecReload=/bin/kill -s HUP $MAINPID
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

2.进入目录，设置开机自启

# cd /etc/systemd/system/
# systemctl enable tomcat

3.其它相关命令

查询当前tomcat的状态：
    # systemctl status tomcat
关闭tomcat：
    # systemctl stop tomcat
关闭开机自启：
    # systemctl disable tomcat
