配置systemctl 管理

创建 tomcat.service

[root@localhost bin]# vi /etc/systemd/system/tomcat.service
[root@localhost bin]# cat /etc/systemd/system/tomcat.service
[Unit]
Description=Tomcat8540
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=oneshot
ExecStart=/home/work/tomcat/apache-tomcat-8.5.55/bin/startup.sh
ExecStop=/home/work/tomcat/apache-tomcat-8.5.55/bin/shutdown.sh
ExecReload=/bin/kill -s HUP $MAINPID
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

[root@localhost bin]# 

启动错误解决

直接使用systemctl启动Tomcat会因找不到java的路径报错

[root@localhost bin]# systemctl start tomcat
Job for tomcat.service failed because the control process exited with error code.
See "systemctl status tomcat.service" and "journalctl -xe" for details.

设置tomcat的java的环境变量
在原文 Make sure prerequisite environment variables are set 前面添加

export JAVA_HOME=/home/work/java/jdk1.8.0_191
export JRE_HOME=/home/work/java/jdk1.8.0_191/jre

[root@localhost bin]# vi setclasspath.sh 

export JAVA_HOME=/home/work/java/jdk1.8.0_191
export JRE_HOME=/home/work/java/jdk1.8.0_191/jre

# Make sure prerequisite environment variables are set
if [ -z "$JAVA_HOME" ] && [ -z "$JRE_HOME" ]; then

使用

• 启动 systemctl start tomcat
• 停止 systemctl stop tomcat
• 状态 systemctl status tomcat
• 打开开机自启 systemctl enable tomcat
• 关闭开机自启 systemctl disable tomcat
