1.服务器状态
服务器A:192.168.1.1
服务器B:192.168.1.2

1.服务器状态
服务器A:192.168.1.1
服务器B:192.168.1.2

 

2.创建同步用户
主机域A:192.168.1.2  用户名A:sync_a  密码A:aaa
主机域B:192.168.1.1  用户名B:sync_b  密码B:bbb
至少分配以下权限grant replication slave

2.创建同步用户
主机域A:192.168.1.2  用户名A:sync_a  密码A:aaa
主机域B:192.168.1.1  用户名B:sync_b  密码B:bbb
至少分配以下权限grant replication slave

准备工作: 

3.执行flush privileges

3.执行flush privileges

1.保证Master/Slave两台主机上mysql的版本一致,避免不必要的麻烦。 

4.停止MySQL

4.停止MySQL

2.保证Master/Slave能够互相ping通,能够通信。 

5.配置my.cnf(my.ini)

5.配置my.cnf(my.ini)

Master主机IP:192.168.1.1 

server-id必须唯一
binlog-do-db和replicate-do-db表示需要同步的数据库教程
binlog-ignore-db和replicate-ignore-db表示不需要同步的数据库
请不要加入以下命令,该命令并不会解决uid跳号的问题,恰恰相反以下两行命令才是导致uid跳号的罪魁祸首
auto_increment_increment = 2
auto_increment_offset = 1

配置my.ini: 

服务器A:
show master status G
flush tables with read lock;
服务器B:
show master status G
flush tables with read lock;

服务器A:
show master status G
flush tables with read lock;
服务器B:
show master status G
flush tables with read lock;

Master – my.ini 

同时记录下两台服务器的File和Position,此处假设:

同时记录下两台服务器的File和Position,此处假设:

在[mysqld]下添加: 

A: File: mysql-bin.000001
  Position: 001
B: File: mysql-bin.000002
  Position: 002

A: File: mysql-bin.000001
Position: 001
B: File: mysql-bin.000002
Position: 002

log-bin = mysql-bin
#因为MYSQL是基于二进制的日志来做同步的,每个日志文件大小为 1G 

服务器A:
change master to
    -> master_host=’192.168.1.2′,
    -> master_user=’sync_b’,
    -> master_password=’bbb’,

server-id = 1 #主标服务标识号,必需唯一 

此处填写的数据完全相反

binlog-do-db = db_user #要同步的库名 

8.执行show processlist G查看是否同步成功

binlog-do-db = db_topic

binlog-ignore-db=mysql,test #不记录日志的库,即不需要同步的库 

两台服务器
192.168.1.1(A)
192.168.1.2(B)
先保证这mysql的版本是一致的,参考

server-id = 2 

执行  #flush privileges; 更新数据库使用户生效。
