• 迁移数据库mysql


     文档 <http://site.clairvoyantsoft.com/migrate-cloudera-scm-database-from-postgresql-to-mysql/> 

    http://node0:7180/api/v14/cm/deployment          -------------正确网址。
    #####1.停止服务;
        1.在UI界面,停止集群;
        2.在UI界面,停止cm的service,monitor等全部服务;
        3.在Linux,停止agent服务:service cloudera-scm-agent stop
    #####2.备份CM配置,通过API ------
        $ curl -v -u admin:admin http://node0:7180/api/<version>/cm/deployment > /home/user/deployment
        本机:
        $ curl -v -u admin:admin http://node0:7180/api/v14/cm/deployment > /home/user/deployment
    注意:这个文件被保留和保护至关重要,因为它将需要重新导入功能配置到新数据库中。(v14)
    Obtain version with: http://manager_host:7180/api/version
    #####3.对postgre的db和server目录做备份。
        #cd /var/lib/cloudera-scm-server-db/
        #tar -cvf /home/user/cloudera-scm-server-db.tar .
        #cd /etc/cloudera-scm-server/
        #tar -cvf /home/user/cloudera-scm-server.tar .
    文件归档在 /home/user/ 下。
    #####4.在server端,停止server,停止server-db,抛弃server-db off
        $ sudo service cloudera-scm-server stop 
        $ sudo service cloudera-scm-server-db stop 
        $ sudo chkconfig cloudera-scm-server-db off 
    #####5.保证mysql server正确安装。--------------------<font color=red>[1]</font>
    #####6.安装、配置mysql软件------<font color=red>[2]</font>
    #####7.创建"temp" db 并且赋权限,记录“示例1:运行脚本当MySQL安装在另一个主机”<font color=red>[3]</font>
        #mysql -h mysql_hostname -u user -p
        mysql> create database temp; 
        mysql> grant all on *.* to 'temp'@'%' identified by 'temp' with grant option; 
    #####8.执行/usr/share/cmf/schema/scm_prepare_database.sh(可重置)
        $/usr/share/cmf/schema/scm_prepare_database.sh mysql -h mysql_hostname  -u user -p --scm-host manager_host <scm_db_name> <scm_user> <scm_password>
    Note:  run $ /usr/share/cmf/schema/scm_prepare_database.sh 
    with no arguments to get syntax assistance
    #####9.开启server服务。
        service httpd start 
        $ sudo service cloudera-scm-server start 
    #####10.Cloudera Manager web用户界面登录和上传企业许可证密钥。
    #####11.重启scm-server
        $ sudo service cloudera-scm-server restart 
    #####12.修复CM配置(step2),通过API---
        $ curl --upload-file /home/user/deployment -u admin:admin http://node0:7180/api/v14/cm/deployment?deleteCurrentDeployment=true -H "Content-Type: application/json"
        //add http header option(恢复集群的命令): -H "Content-Type: application/json" ..if required
        //verify that there are no errors, the command prints the api even on connection failure.
    #####13.登录CM,验证当前的配置选项。所有服务现在应该可用但是停止状态。

        尝试,所有主机-重新运行升级向导。

    #####14.cleanup: 
        $ yum erase cloudera-manager-server-sb
    #####15.如果scm-agent启动失败,你必须删除或者一出pid ./var/lib/cloudera-scm-agent/ 并且重启agent。

    参考网址1-----配置mysql server和jdbc driver:
    1.



    参考网址3:在另一台主机配置mysql2,连接mysql1。

    3、 查看postgresql 的scm用户的密码
    grep password /etc/cloudera-scm-server/db.properties
    会得到如下信息:
    [root@hadoop1 /]# grep password /etc/cloudera-scm-server/db.properties
    com.cloudera.cmf.db.password=pfxlUudKJo

    4、 登陆postgresql 数据库
    psql -h localhost -p 7432 -U scm
    输入第三步查到的密码

    /usr/share/cmf/schema/scm_prepare_database.sh postgresql scm scm scm

    /etc/init.d/cloudera-manager-server-db restart

    **guid删除,重新运行升级向导**
    /var/lib/cloudera-scm-agent/cm_guid 删除guid--主机状况不良(由于原集群的guid存在唯一性,过时)
