【原创】mysql-utilities工具体验

分类： Mysql/postgreSQL

2013-05-14 12:53:41

我主要体验了下几个关于REPLICATION的工具。 其他的可以参见手册。
先说下我的环境：
MASTER: 192.168.1.131
SLAVE: 192.168.1.132, 192.168.1.133
三台DB都有对外的ALL权限用户。
各个配置文件如下，



点击(此处)折叠或打开

  1. [root@mysql56-master home]# cat /etc/my.cnf
  2. [mysqld]
  3. user = ytt
  4. skip-name-resolve


  7. innodb_buffer_pool_size = 128M




  12. basedir = /usr/local/mysql
  13. datadir = /usr/local/mysql/data
  14. port = 3306
  15. server_id = 131
  16. socket = /tmp/mysql.sock






  23. explicit_defaults_for_timestamp
  24. log-bin=mysql56-master-bin
  25. binlog-ignore-db=mysql


  28. gtid-mode=on
  29. enforce-gtid-consistency
  30. log-slave-updates


  33. binlog-format=ROW
  34. sync-master-info=1
  35. report-host=192.168.1.131
  36. report-port=3306




  41. master_info_repository=table
  42. relay_log_info_repository=table



其他两台SERVER，除了SERVER-ID，都基本相同，我就不贴了。


1. MYSQLREPLICATE 搭建主从的脚本，这里我搭建了两台从机。

  1. mysqlreplicate --master=root:root@192.168.1.131:3306 --slave=root:root@192.168.1.132:3306;...
  2. [root@mysql56-master home]# ./replicate_create
  3. # master on 192.168.1.131: ... connected.
  4. # slave on 192.168.1.132: ... connected.
  5. # Checking for binary logging on master...
  6. # Setting up replication...
  7. # ...done.
  8. # master on 192.168.1.131: ... connected.
  9. # slave on 192.168.1.133: ... connected.
  10. # Checking for binary logging on master...
  11. # Setting up replication...
  12. # ...done.




2. mysqlrplcheck  检查主从的运行情况。

  1. [root@mysql56-master home]# mysqlrplcheck --master=root:root@192.168.1.131:3306 --slave=root:root@192.168.1.132:3306 -s
  2. # master on 192.168.1.131: ... connected.
  3. # slave on 192.168.1.132: ... connected.
