centos 开机启动java_Centos 7将java jar包自定义开机启动服务

Centos 7将java jar包自定义开机启动服务

1. 先上 jar包的启动脚本

vim service.sh

#!/bin/bash

# 需要变更的参数

# 先查看java绝对路径：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

写好脚本之后，需要为脚本添加可执行权限

chmod +x service.sh

2. 自定义开机启动命令

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. 添加开机启动服务

#添加开机启动服务

systemctl enable odms

# 启动服务

systemctl start odms

#关闭服务

systemctl stop odms

# 重启服务

systemctl restart odms

#查看服务状态

systemctl status doms

#取消开机启动

systemctl disable odms
