MYSQL使用心得(二) 主从复制
基本配置
主数据库 配置文件,修改server_id=1 建立账户,供slave同步使用 GRANT REPLICATION SLAVE ON *.* to 'repl'@'192.168.56.3' identified by 'repl'; Mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000005 | 261 | | | +------------------+----------+--------------+------------------+ 记录下 FILE 及 Position 的值,在后面进行从服务器操作的时候需要用到。 从数据库 配置文件,修改server_id=2 执行同步SQL语句,地址为主数据库地址,和主数据库上的用户名和密码 change master to master_host='192.168.56.2', master_user='repl', master_password='repl', master_log_file='mysql-bin.000005', master_log_pos=261; 正确执行后启动Slave同步进程 start slave; 主从同步检查 mysql> show slave statusG ============================================== *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.56.2 Master_User: test Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000008 Read_Master_Log_Pos: 258 Relay_Log_File: Slave2-relay-bin.000003 Relay_Log_Pos: 404 Relay_Master_Log_File: mysql-bin.000008 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 258 Relay_Log_Space: 561 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1 ============================================== 其中Slave_IO_Running 与 Slave_SQL_Running 的值都必须为YES,才表明状态正常。 (编辑:应用网_丽江站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
