*  ## 编写jar包的可执行启动文件 ##

首先新建一个文件

vim run.sh

内容如下

#!/bin/sh
    nohup /usr/local/jdk1.8/bin/java -jar -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xms1024m -Xmx1024m -Xmn256m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC /home/zhtel/tydic/tydic-admin.jar >/home/zhtel/logs/tydic.out 2>&1 &

给文件加上可执行权限

chmod a+x run.sh

*  # 将run.sh添加到系统服务 #

进入到目录

/etc/systemd/system/

新建文件xxx.service,内容如下：

#!/bin/sh
    
    [Unit]
    Description = tydic-admin
    After=syslog.target network.target remote-fs.target nss-lookup.target network.target network-online.target dbus.service
    
    
    [Service]
    Type = forking
    ExecStart = /home/zhtel/tydic/run.sh
    PrivateTmp=true
    Restart=always
    RestartSec=1
    
    [Install]
    WantedBy = multi-user.target

给文件赋权754，chmod 754 xxx.service

*  # 将服务添加到开机自启 #

systemctl daemon-reload #重载系统服务
    systemctl start xxx.service #启动服务
    systemctl enable xxx.service #将服务设置为开机自启
    systemctl disable xxx.service #将服务取消开机自弃
    systemctl status xxx.service #查看服务状态

reboot重启服务器后查看服务运行状态，结果如下：

[root@localhost system]# systemctl status tydic-admin.service
    ● tydic-admin.service - tydic-admin
       Loaded: loaded (/etc/systemd/system/tydic-admin.service; enabled; vendor preset: disabled)
