改进版重启java 程序，及配合ansible yml 批量执行

Posted 2020-08-08

原先的lsof -i:port 方式重启java 程序经常会有些小问题，这里改进了新脚本，并且结合ansilbe 使用，直接上脚本和样例。

1. restat-tm.sh

#!/bin/bash

JAVA_HOME="/usr/local/java/jdk1.8.0_25" ###jdk 

APP_MAINCLASS="TM" ###TM.jar

APP_HOME="/home/java/tm" ####/home/java/tm/***

#java虚拟机启动参数

JAVA_OPTS="-ms512m -mx512m -Xmn256m -Djava.awt.headless=true -XX:MaxPermSize=128m  -Dfile.encoding=UTF-8  "

psid=0

##########################################checkpid()#################################

checkpid() {

   javaps=`$JAVA_HOME/bin/jps -l | grep $APP_MAINCLASS`

   if [ -n "$javaps" ]; then

      psid=`echo $javaps | awk ‘{print $1}‘`

   else

      psid=0  ####[ $psid -ne 0 ]

   fi

echo "checkpid:"+$psid

}

##########################################start ()#################################

start() {

   checkpid

   if [ $psid -ne 0 ]; then

      echo "================================"

      echo "warn: $APP_MAINCLASS already started! (pid=$psid)"

      echo "================================"

   else

      echo -n "Starting $APP_MAINCLASS ..."

 nohup $JAVA_HOME/bin/java $JAVA_OPTS -jar $APP_HOME/$APP_MAINCLASS.jar > /dev/null 2>&1 &

      checkpid

      if [ $psid -ne 0 ]; then

         echo "(pid=$psid) [start OK]"

      else

         echo "[start Failed]"

      fi

   fi

}

##########################################stoppid()#################################

stop() {

   checkpid

   if [ $psid -ne 0 ]; then

      echo -n "Stopping $APP_MAINCLASS ...(pid=$psid) "

      kill   $psid

      if [ $? -eq 0 ]; then

         echo "[stop OK]"

      else

         echo "[stop Failed]"

      fi

      checkpid

      if [ $psid -ne 0 ]; then

         stop   ###验证重杀

      fi

   else

      echo "================================"

      echo "warn: $APP_MAINCLASS is not running"

      echo "================================"

   fi

}

##########################################status ()#################################

status() {

   checkpid

   if [ $psid -ne 0 ];  then

      echo "$APP_MAINCLASS is running! (pid=$psid) and run time is :"

      ps -p  $psid -o pid,etime,uid,gid

   else

      echo "$APP_MAINCLASS is not running"

   fi

}

##########################################info)#################################

   echo "****************************"

   echo `head -n 1 /etc/issue`

   echo `uname -a`

   echo

   echo `$JAVA_HOME/bin/java -version`

   echo

   echo "APP_HOME=$APP_HOME"

   echo "APP_MAINCLASS=$APP_MAINCLASS"

   echo "****************************"

}

##########################################op ()#################################
