环境：
Centos7、JDK 1.8、Tomcat9
安装好JDK跟Tomcat后在/usr/lib/systemd/system/目录下新建文件tomcat.service，内容如下，对应的位置替换一下
[Unit] Description=Tomcat9 After=syslog.target network.target remote-fs.target nss-lookup.target [Service] Type=forking Environment='JAVA_HOME=/opt/jdk/jdk' #JDK安装位置 Environment='CATALINA_PID=/opt/tomcat9/bin/tomcat.pid' Environment='CATALINA_HOME=/opt/tomcat9/'#Tomcat安装位置 Environment='CATALINA_BASE=/opt/tomcat9/' Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC' WorkingDirectory=/opt/tomcat9/ ExecStart=/opt/tomcat9/bin/startup.sh ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target
设置为开启机启动：systemctl enable tomcat
其它命令：
启动服务：systemctl start tomcat
停止服务：systemctl stop tomcat
重启服务：systemctl restart tomcat
检查状态：systemctl status tomcat
重启机子后可以看下是否Tomcat已经随机启动了：http://192.168.95.198:8080/
