java 通過shell 管理 tomcat

1. java代碼

 		String tomcat_state = (String) config.getProperty("monitor_path"); // 檢測tomcat
        Process ps =Runtime.getRuntime().exec(tomcat_state);
        ps.waitFor();
        InputStream in = ps.getInputStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        StringBuffer sb = new StringBuffer();
        String line = "";
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }
        System.err.println(sb.toString());

2. 關閉tomcat shell腳本 stop.sh

#! /bin/bash
tomcat_home=/opt/module/tomcats/apache-tomcat-9.0.0.M15-8086
SHUTDOWN=${tomcat_home}/bin/shutdown.sh
StartTomcat=${tomcat_home}/bin/startup.sh
TomcatCache=${tomcat_home}/work
	echo "開始停止 tomcat"
	${SHUTDOWN}
	sleep 2
	TomcatID=$(ps -ef |grep tomcat |grep -w 'apache-tomcat-9.0.0.M15-8086'|grep -v 'grep'|awk '{print $2}') 
	if [! $TomcatID ];then # 這裏判斷TOMCAT進程是否存在  
		echo "[info] tomcat停止成功  success"  
  	else  
	echo "[info]當前tomcat進程ID爲:$TomcatID  tomcat停止成功  success "
    	kill -9 $TomcatID   
    fi  

3. 啓動tomcat shell 腳本 start.sh

#! /bin/bash
tomcat_home=/opt/module/tomcats/apache-tomcat-9.0.0.M15-8086
SHUTDOWN=${tomcat_home}/bin/shutdown.sh
StartTomcat=${tomcat_home}/bin/startup.sh
TomcatCache=${tomcat_home}/work
#定義要監控的頁面地址  
WebUrl=http://140.143.147.167:8086/

  echo "[info]tomcat.start"
  ${StartTomcat}
  sleep 3
  TomcatID=$(ps -ef |grep tomcat |grep -w 'apache-tomcat-9.0.0.M15-8086'|grep -v 'grep'|awk '{print $2}') 
  if [ ! $TomcatID ];then # 這裏判斷TOMCAT進程是否存在  
    echo "[error]tomcat進程不存在!tomcat啓動出錯...error"  
  else  	
	 echo "[info]當前tomcat進程ID爲:$TomcatID,休眠60s後檢測頁面..."
     sleep 60  
     #訪問監控地址，檢測是否啓動成功(成功的話頁面會返回狀態"200")  
     TomcatServiceCode=$(curl -I -m 10 -o /dev/null -s -w %{http_code} $WebUrl)  
     if [ $TomcatServiceCode -eq 200 ];then  
        echo "[info]tomcat啓動成功...success"  
     elif [ $TomcatServiceCode -eq 000 ];then  
    	  echo "[error]tomcat啓動出錯...error"  
     else  
        echo "[error]tomcat啓動出錯...error"  
     fi  
  fi  

4. 檢測tomcat 是否啓動 monitor.sh

#! /bin/sh
#定義要監控的頁面地址  
WebUrl=http://140.143.147.167:8086/
TomcatID=$(ps -ef |grep tomcat |grep -w 'apache-tomcat-9.0.0.M15-8086'|grep -v 'grep'|awk '{print $2}')
if[!TomcatID];then
	TomcatServiceCode=$(curl -I -m 10 -o /dev/null -s -w %{http_code} $WebUrl)  
	    if [ $TomcatServiceCode -eq 200 ];then  
	       echo "tomca啓動正常 success"
	
	    elif [ $TomcatServiceCode -eq 000 ];then  
	    	 echo "tomcat沒有啓動 error"   
	       
	    else  
	        echo "[error]tomcat啓動出錯...error"  
	    fi  
else
	echo "[error]tomcat啓動出錯...error"  
fi
