以testing.jar项目为例写一个启动脚本
假如项目安装在/usr/local/testing目录下
[root@froeasy ~]#cat /usr/local/testing/test_service.sh
#!/bin/bash
# 需要变更的参数
java=/usr/java/jdk1.8.0_181/bin/java
STARTUP="$java -server -XX:MetaspaceSize=640m -XX:MaxMetaspaceSize=640m -Xms1024m -Xmx4096m -Xmn512m -Xss1024k -XX:SurvivorRatio=8 -XX:+UseConcMarkSweepGC -jar"
JAR=`ls /usr/local/testing/*.jar -th |head -1`
cd /usr/local/testing/
function start () {
nohup $STARTUP $JAR >> /usr/local/testing/log/testing.log 2>&1 &
exit 0
}
function stop () {
PID=`ps aux|grep "$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
在写个服务文件：
[root@froeasy ~]# cat /usr/lib/systemd/system/testing.service
[Unit]
Description=Java
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
User=root
Group=root
Type=forking
ExecStart=/usr/local/testing/test_service.sh start
ExecReload=/usr/local/testing/test_service.sh reload
ExecStop=/usr/local/testing/test_service.sh stop
PrivateTmp=true
[Install]
WantedBy=multi-user.target
记得每次修改服务后要使用以下命令
[root@froeasy ~]# systemctl daemon-reload
常用命令
[root@froeasy ~]# systemctl start testing
[root@froeasy ~]# systemctl restart testing
[root@froeasy ~]# systemctl stop testing
