（1）修改脚本文件

[root@localhost bin]# vim /data/apache-tomcat-9.0.56/bin/catalina.sh

添加以下内容(如图)

JAVA_HOME=/usr/jdk1.8.0_202JRE_HOME=$JAVA_HOME/jre

（2）在/usr/lib/systemd/system/中创建tomcat9.service文件

[root@localhost apache-tomcat-9.0.56]# vim /usr/lib/systemd/system/tomcat9.service

粘贴下面的内容到tomcat9.service文件

[Unit]Description=TomcatAfter=syslog.target network.target remote-fs.target nss-lookup.target [Service]Type=oneshotExecStart=/data/apache-tomcat-9.0.56/bin/startup.shExecStop=/data/apache-tomcat-9.0.56/bin/shutdown.shExecReload=/bin/kill -s HUP $MAINPIDRemainAfterExit=yes[Install]WantedBy=multi-user.target
