 1. 先上 jar包的啟動腳本

vim service.sh

#!/bin/bash
# 需要變更的參數
# 先查看java絕對路徑：which java
java=/data/app/jdk/bin/java
STARTUP="$java -server -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=128m -Xms512m -Xmx512m -Xmn128m -Xss256k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -Dspring.profiles.active=dev -jar"
PROJECT="odms"
LISTEN_PORT="8092"
JAR=`ls /data/www/$PROJECT-$LISTEN_PORT/*.jar -th |head -1`

cd /data/www/$PROJECT-$LISTEN_PORT

function start () {
    nohup $STARTUP $JAR >> /data/logs/$PROJECT-$LISTEN_PORT/$PROJECT.log 2>&1 &
    exit 0
}

function stop () {
    PID=`ps aux|grep "$JAR"|grep -v grep|awk '{print $2}'`
    if [ -z $PID ];then
        exit 0
    else
        kill -9 $PID
    fi
}

function reload () {
    PID=`ps aux|grep "$JAR"|grep -v grep|awk '{print $2}'`
    if [ -z $PID ];then
        exit 0
    else
        kill -1 $PID
    fi
}
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    reload)
        reload
        ;;
    restart)
        stop
        sleep 3
        start
        ;;
    *)
        echo "start|stop|reload|restart"
        ;;
esac

 

寫好腳本之后，需要為腳本添加可執行權限

chmod +x service.sh

 

 

2. 自定義開機啟動命令

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

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

[Service]
User=dev
Group=dev

Type=forking

ExecStartPre=/bin/cd /data/www/odms-8092/
ExecStart=/data/www/odms-8092/service.sh start
ExecReload=/data/www/odms-8092/service.sh reload
ExecStop=/data/www/odms-8092/service.sh stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

 

 systemctl daemon-reload

 

3. 添加開機啟動服務

#添加開機啟動服務
systemctl enable odms
# 啟動服務
systemctl start odms
#關閉服務
systemctl stop odms  
# 重啟服務
systemctl restart odms
#查看服務狀態
systemctl status doms
#取消開機啟動
systemctl disable odms
