## 1. 编写开机启动脚本 ##

[root@cassandra-01 ~]# cd /etc/rc.d/init.d/
    [root@cassandra-01 init.d]# vi cassandra
    写入以下内容并保存关闭
    #!/bin/sh
    # chkconfig: 2345 60 60
    # description: service for cassandra 3.10, 2018-12-28
    # processname: casandra
    
    CASSANDRA_DIR="/your/path/cassandra"
    
    case "$1" in
            start)
                    echo "Starting cassandra"
                    su - cassandra -c nohup -c "$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
    赋予权限
    [root@cassandra-01 init.d]# chmod 755 cassandra

## 2. 配置开机自启动 ##

加入系统服务

[root@cassandra-01 init.d]# chkconfig --add cassandra

设置开机自启动

[root@cassandra-01 init.d]# chkconfig cassandra on

## 3. 服务启动停止 ##

[root@cassandra-01 init.d]# service cassandra start
    [root@cassandra-01 init.d]# service cassandra stop
    [root@cassandra-01 init.d]# service cassandra restart
