这篇文章主要讲解了“mysql传统主从复制的部署过程”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“mysql传统主从复制的部署过程”吧! 部署过程 一、保证Master库和Slave库的数据和结构一致 可以通过mysqldump或者XtraBackup工具对Master库进行全备,再把备份文件传到Slave库,Slave库利用改备份进行恢复,使得两者一致。 我这里的Slave库是直接复制Master库生成的,所以不需要做这一步了。 二、配置两个库的参数文件 Master库需要打开二进制日志 Master库需要设置与Slave库不同的server-id [root@potato data]vi /etc/my.cnf binlog_format = mixed server-id = 203306 log-bin = mybinlog Slave库只需配置server-id即可 [root@tomato data]vi /etc/my.cnf server-id = 203307 三、创建用来进行复制的用户并且赋权 必须给予用户replication slave权限,指定Slave库的主机地址 点击(此处)折叠或打开 root@localhost:mysql.sock 05:02:32 [(none)]>grant replication slave on *.* to repl@'192.168.161.128' identified by 'repl'; 四、让Slave库change到Master库 查看Master库此时的日志位置 点击(此处)折叠或打开 root@localhost:mysql.sock 05:02:32 [(none)]>show master status ; +-----------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +-----------------+----------+--------------+------------------+-------------------+ | mybinlog.000004 | 331 | | | | +-----------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec) 从库开始change到master库上 点击(此处)折叠或打开 root@localhost:mysql.sock 04:29:15 [(none)]>change master to -> master_host='192.168.161.128', -> master_port=3306, -> master_user='repl', -> master_password='repl', -> master_log_file='mybinlog.000004', -> master_log_pos=331; ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect... Connection id: 2 Current database: *** NONE *** Query OK, 0 rows affected, 2 warnings (0.17 sec) 五、Slave库执行开始复制命令 点击(此处)折叠或打开 root@localhost:mysql.sock 04:40:11 [(none)]>start slave; 到此,主从复制就已经配置完毕了 六、对搭建的环境进行测试测试 主库开始插入数据测试 点击(此处)折叠或打开 root@localhost:mysql.sock 04:40:11 [(none)]>use lala; root@localhost:mysql.sock 04:51:23 [(lala)]>create table haha(id int); root@localhost:mysql.sock 04:51:23 [(lala)]>insert into haha values(1); 从库是否接受到数据 点击(此处)折叠或打开 root@localhost:mysql.sock 04:52:55 [(none)]>select * from lala.haha; +------+ | id | +------+ | 1 | +------+ 1 row in set (0.00 sec) 查看Slave状态 点击(此处)折叠或打开 root@localhost:mysql.sock 04:57:23 [(none)]>show slave statusG *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.161.128 Master_User: repl Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mybinlog.000004 Read_Master_Log_Pos: 620 Relay_Log_File: mysql-relay-bin.000003 Relay_Log_Pos: 571 Relay_Master_Log_File: mybinlog.000004 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: 620 Relay_Log_Space: 744 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: 203306 Master_UUID: af3609cd-b426-11e6-a997-000c29d55626 Master_Info_File: /data/mysql/mytest_3306/data/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for the slave I/O thread to update it Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: Executed_Gtid_Set: Auto_Position: 0 1 row in set (0.00 sec) 主从复制部署测试成功 感谢各位的阅读,以上就是“mysql传统主从复制的部署过程”的内容了,经过本文的学习后,相信大家对mysql传统主从复制的部署过程这一问题有了更深刻的体会,具体使用情况还需要大家实践验证。 (编辑:随州站长网) 【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! |
