[Transfer] Java package settings under Linux to start automatically at boot

1. Add startup script in any location

vim xxxx.sh

#!/bin/sh

cd /usr/local/java/ydServer/target #切换到jar包所在目录
pid=`ps -ef|grep 'xxxx.jar*'|grep -v grep|awk '{print $2}'`
if [ -n "${pid}" ];then
    kill -9 ${pid}
    echo "Process ITSM killed!"
    #java 根据自己jdk路径填写, jar包写绝对路径
    nohup java -Dfile.encoding=utf-8 -jar xxxx.jar >/xxxx/xxxx.txt 2>&1 &
    echo "Restart ITSM Success!"
else
    nohup java -Dfile.encoding=utf-8 -jar xxxx.jar >/xxxx/xxxx.txt 2>&1 &
    echo "Start ITSM Success!"
fi

2. Authorization script file

chmod 777 xxx.sh

3. Configure service file

vim /etc/systemd/system/xxx.service

[Unit]
Description=xxx-service
After=network.target

[Service]
Type=forking
ExecStart=/xxx/xxxx.sh

[Install]
WantedBy=multi-user.target

4. Set as service

#重载系统服务
systemctl daemon-reload
#测试 服务是否生效   
systemctl  start  demo.service  
ps aux|grep demo

#查看jar包运行情况
ps -ef|grep '***.jar'
 
# 设置服务为开机启动服务
systemctl enable demo.service
 
#开机服务查询
systemctl list-units --type=service
