cassandra自啟動服務器腳本

1. 新建一個文件。
   

   vi /etc/rc.d/init.d/vi cassandra2

   #!/bin/sh
   # chkconfig: 2345 60 60
   # description: service for cassandra 2.1.x from arges 2016-06-22
   # processname: casandra2
   
   echo "welcome to use cassandra 2.1.x's service script from zxj"
   
   CASSANDRA_DIR="/opt/cassandra/apache-cassandra-2.1.14"
   
   case "$1" in
           start)
                   echo "starting cassandra******"
                   nohup -c "$CASSANDRA_DIR/bin/cassandra" >> $CASSANDRA_DIR/logs/system.log 2>&1 &
                   echo "cassandra started"
                   ;;
           stop)
                   echo "stopping cassandra******"
                   PID_COUNT=`ps aux |grep CassandraDaemon |grep -v grep | wc -l`
                   PID=`ps aux |grep CassandraDaemon |grep -v grep | awk {'print $2'}`
                   if [ $PID_COUNT -gt 0 ];then
                           echo "*********try stop cassandra***********"
                           kill -9 $PID
                           echo "*********kill cassandra SUCCESS!***********"
                   else
                           echo "*********there is no cassandra!***********"
                   fi
                   ;;
           restart)
                   echo "restarting cassandra******"
                   $0 stop
                   $0 start
                   ;;
       status)
           -c "$CASSANDRA_DIR/bin/nodetool status"
           ;;
       *)
           echo "Usage:$0 {start|stop|restart|status}"
           exit 1
   esac

2. 設置服務自啟動
   

   chmod 755 /etc/rc.d/init.d/cassandra2
   chkconfig --add cassandra2

3. 測試
   

   service cassandra2 start  //啟動
   service cassandra2 stop  //關閉
   service cassandra2 restart  //重啟

   這個腳本是從別人那里借鑒過來，原來的重啟好像有點問題，改好之后應該沒問題了。
