cdh集群测试环境启停脚本

1. 环境介绍

　　当前测试环境总共由4个CentOS7服务器构建，域名分别为cm,cdh-worker1,cdh-worker2,cdh-worker3,其中cm是管理节点安装有mysql软件，其他都是工作节点

2. 启停脚本

#!/usr/bin/env bash
# 启动+关闭+重启CM集群脚本
if [ $# -lt 1 ]
then
    echo "No Args Input... option args : start,restart,stop"
    exit ;
fi

case $1 in
"start")
        echo " =================== 启动 cm集群 启动顺序 mysql -->cloudera-scm-server --> cloudera-scm-agent==================="
        ssh cdh-cm service mysql start
        sleep 5s
        ssh cdh-cm service cloudera-scm-server start
        ssh cdh-worker1 service cloudera-scm-agent start
        ssh cdh-worker2 service cloudera-scm-agent start
        ssh cdh-master service cloudera-scm-agent start
        echo " =================== 启动 cm集群 启动成功==================="
;;
"stop")
        echo " =================== 关闭cm集群 关闭顺序  cloudera-scm-agent--> cloudera-scm-server  ==================="
        ssh cdh-worker1 service cloudera-scm-agent stop
        ssh cdh-worker2 service cloudera-scm-agent stop
        ssh cdh-master service cloudera-scm-agent stop
        ssh cdh-cm service cloudera-scm-server stop
        echo " =================== 关闭cm集群成功==================="
;;
"restart")
        echo " =================== 重启cm集群  启动顺序  cloudera-scm-server --> cloudera-scm-agent ==================="
        ssh cdh-cm service cloudera-scm-server restart
        sleep 10s
        ssh cdh-worker1 service cloudera-scm-agent restart
        ssh cdh-worker2 service cloudera-scm-agent restart
        ssh cdh-master service cloudera-scm-agent restart
