java -jar自动化

入职公司，基建有待提高，考虑将命令行部署服务进行脚本自动化。

写了find.sh、findAndKill.sh、start.sh 3个脚本实现

find.sh

jarName='business-start-1.0.0.jar'
pid=$(echo `ps -ef | grep $jarName` | cut -d' ' -f2)
echo "pid $pid"
if [ -n "$pid" ]
        then
                echo "$jarName STARTED"
        else
                echo "NOT FOUND $jarName"
fi

findAndKill.sh

jarName='business-start-1.0.0.jar'
pid=$(echo `ps -ef | grep $jarName` | cut -d' ' -f2)
echo "pid $pid"
if [ -n "$pid" ]
        then
                echo "WARNNING... start to kill $pid"
                kill $pid
                echo "pid $pid is killed"
        else
                echo "NOT FOUND $jarName"
fi

start.sh

jarName='business-start-1.0.0.jar'

# start daemon
nohup java -XX:+UseG1GC -Xmx10240m -XX:MaxGCPauseMillis=200 -jar $jarName > /dev/null 2>&1 &

#waitting for jar start
sleep 3s

#get pid
pid=$(echo `ps -ef | grep $jarName` | cut -d' ' -f2)

echo "pid $pid"

# not empty
if [ -n "$pid" ]
        then
                echo "$jarName STARED"
        else
                echo "NOT FOUND $jarName"
fi
