CentOS7.6设置tomcat自启

vi /usr/lib/systemd/system/tomcat8.service

文件内容如下

[Unit]
Description=Tomcat8
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment='JAVA_HOME=/usr/java'
Environment='CATALINA_PID=/usr/local/tomcat8/bin/tomcat.pid'
Environment='CATALINA_HOME=/usr/local/tomcat8/'
Environment='CATALINA_BASE=/usr/local/tomcat8/'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'

WorkingDirectory=/usr/local/tomcat8/

ExecStart=/usr/local/tomcat8/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=false

[Install]
WantedBy=multi-user.target

退出并保存文件

注意：需要注意的文件夹名字和路径一定要对应

执行systemctl enable tomcat8.service使tomcat开机启动 

systemctl start tomcat8.service 启动tomcat

systemctl stop tomcat8.service 结束tomcat

systemctl restart tomcat8.service 重启tomcat

systemctl status tomcat8.service 查看tomcat状态

 

如果要设置多个TOMCAT启动，可以修改服务名字和路径，举例如下

vi /usr/lib/systemd/system/tomcat8081.service

[Unit]
Description=Tomcat8081
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment='JAVA_HOME=/usr/java'
Environment='CATALINA_PID=/usr/local/tomcat8081/bin/tomcat.pid'
Environment='CATALINA_HOME=/usr/local/tomcat8081/'
Environment='CATALINA_BASE=/usr/local/tomcat8081/'

WorkingDirectory=/usr/local/tomcat8081/

ExecStart=/usr/local/tomcat8081/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=false

[Install]
WantedBy=multi-user.target

退出保存

 另外要注意的是一旦修改自启服务配置文件，就要让 SystemD 重新加载配置文件，然后重新启动，否则修改不会生效。命令为systemctl daemon-reload

 

 vim /usr/lib/systemd/system/tomcat9.service

[Unit]
Description=Tomcat9
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
Environment='JAVA_HOME=/usr/java'
Environment='CATALINA_PID=/usr/local/tomcat9/bin/tomcat.pid'
Environment='CATALINA_HOME=/usr/local/tomcat9/'
Environment='CATALINA_BASE=/usr/local/tomcat9/'
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'

WorkingDirectory=/usr/local/tomcat9/

ExecStart=/usr/local/tomcat9/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=false

[Install]
WantedBy=multi-user.target
