一键启动HBase脚本所解决的问题：

*  解决一台一台启动zookeeper繁琐问题
 *  解决因时间不同步导致HBase启动失败的问题

脚本编写hbase-start.sh：

# !/bin/bash
    
    hbase_master=bigdata-pro-m07
    
    cat /opt/modules/hbase/onekey/slave | while read line
    do
    { 
     echo $line + "同步时间"
     ssh $line ntpdate cn.pool.ntp.org
     ssh $line "source /etc/profile;${ZOOKEEPER_HOME}/bin/zkServer.sh start"
    }&
    wait
    done
    
    ssh $hbase_master ${ HBASE_HOME}/bin/start-hbase.sh

赋予权限：

chmod u+x hbase-start.sh

启动测试：

bigdata-pro-m07 + 同步时间
