一、部署prometheus,grafana和node\_exporterPrometheus开始教程：1.1环境(centos7)root@localhostprometheusunameaLinuxlocalhost.localdomain3.10

fromsqlalchemyimportcreate_engine,Table,Column,Integer,String,MetaData,ForeignKeyenginecreate_engine("mysqlpymysql://root:a5230411@localhost:3306/test",echoTrue)

创建JOB sqoopjobDmapreduce.job.queuename'root.bi'creatext\_test\_jobimportconnectjdbc:mysql://xxxx:3306/test?tinyInt1isBitfalseusernamexxxpasswordxxx

linux下重启网卡使用命令：servicenetworkrestart时报错：root@slave01hadoopservicenetworkrestartStartingnetwork(viasystemctl):Jobfornetwork.servicefailedbecausethe

1.安装1.1.MySQL  $sudoaptgetinstallmysqlservermysqlclient    过程中输入root密码  $sudonetstattanp|grepmysql1.2.Apache2  $sudoaptget
