windows下MySQL主从复制配置

windows下MySQL主从复制配置

    • 前言
    • 配置主库
    • 从库配置
    • 建库脚本

前言

  • jdk1.8
  • Mycat-server-1.6
  • sqlyog
  • MySQL 版本5.7(主从库均是)
  • 主库IP:192.168.0.118,从库IP:192.168.0.145
  • 局域网内测试
  • 建库脚本在末尾

配置主库

  1. 停止主库MySQL服务

  2. 打开主库my.ini文件进行如下配置, 请注意看注释,根据自己的情况修改:

    [mysql]
    # 设置mysql客户端默认字符集
    default-character-set = utf8
    [mysqld]
    # 设置3306端口
    port = 3306
    # 设置mysql的安装目录
    basedir = D:\BtSoft\WebSoft\mysql\MySQL5.7\
    # 设置mysql数据库的数据的存放目录
    datadir = D:\BtSoft\WebSoft\mysql\MySQL5.7\data\
    # 允许最大连接数
    max_connections = 200
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character-set-server = utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine = INNODB
    #=========主从复制关键配置=====================
    # 服务器唯一ID, 主库和从库需要不一致, 1至32, 手动设定, 这里配置为1, 等会从库配置为2, 一般取IP最后一段
    server-id = 1
    #主从复制的数据库的名字, 如果此项不配置所有主库都参与复制, 如果想复制多个库, 就多复制几行就好了,千万别写成这样binlog-do-db=db1, db2, db3, 我试了这样不行
    binlog-do-db = db1
    binlog-do-db = db2
    binlog-do-db = db3
    #不需要复制的库,和上项同理, 这里忽略mysql数据库
    binlog-ignore-db = mysql
    #启用二进制日志
    log-bin = mysql-bin
    #=========主从复制关键配置=====================
    

    如果安装的MySQL没有my.ini文件的话,自己手动创建一个放在MySQL的安装目录(如 :D:\BtSoft\WebSoft\mysql\MySQL5.7\my.ini)即可,这里需要注意MySQL的安装目录千万不要有空格,默认安装的MySQL是在C:\Program Files\MySQL\MySQL Server 5.7这个目录下,我试了不行, 必须不能有空格

  3. 配置好之后保存,重启主库MySQL服务即可。

  4. 在主库中建立一个用户(专门用给从库连接的,注意这是在主库里面建立的),执行以下SQL:

    -- 主库执行
    -- 在主库中建立一个用户(专门用给从库连接的,注意这是在主库里面建立的) 
    -- daier是用户名, 后面的111111是密码, 192.168.0.145 是从库IP
    grant replication slave,reload,super on *.* to daier@192.168.0.145 identified by '111111' ; 
    
  5. 刷新权限, 执行以下SQL:

    flush privileges;
    
  6. 显示主库状态, 执行以下SQL:

    show master status;
    

    在查询结果中找到FilePosition的值记录下来, 配置从库时需要使用。

从库配置

  1. 停止从库服务

  2. 打开从库my.ini文件进行如下配置, 请注意看注释,根据自己的情况修改:

    [mysql]
    # 设置mysql客户端默认字符集
    default-character-set = utf8
    [mysqld]
    #设置3306端口
    port = 3306
    # 设置mysql的安装目录
    basedir = D:\BtSoft\WebSoft\mysql\MySQL5.7\
    # 设置mysql数据库的数据的存放目录
    datadir = D:\BtSoft\WebSoft\mysql\MySQL5.7\data\
    # 允许最大连接数
    max_connections = 200
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character-set-server = utf8
    # 创建新表时将使用的默认存储引擎
    default-storage-engine = INNODB
    #=========主从复制关键配置=====================
    #服务器唯一ID, 主库和从库需要不一致, 1至32, 手动设定, 这里配置为2, 一般取IP最后一段
    server-id = 2
    #主从复制的数据库的名字, 如果此项不配置所有主库都参与复制, 如果想复制多个库, 就多复制几行就好了,千万别写成这样binlog-do-db=db1, db2, db3, 我试了这样不行
    binlog-do-db = db1
    binlog-do-db = db2
    binlog-do-db = db3
    #不需要复制的库,和上项同理, 这里忽略mysql数据库
    binlog-ignore-db = mysql
    #启用二进制日志
    log-bin = mysql-bin
    #=========主从复制关键配置=====================
    

    注意上面的server-id这个配置一定不要和主库一样

  3. 配置好之后保存,重启主库MySQL服务即可。

  4. 在从库执行以下SQL,连接主库:

    -- 从库执行
    change master to master_host = '192.168.0.118', -- 这里填你主库的IP
    master_user = 'daier', -- 刚才我们创建的那个用户
    master_password = '111111', -- 密码
    master_log_file = 'mysql-bin.000003', -- 刚才在主库里面 show master status;得到的File值
    master_log_pos = 1783, -- 刚才在主库里面 show master status;得到的Position值
    master_port = 3306; -- 端口,默认是3306, 如果你是3306可以不写
    
  5. 从库执行

    -- 停止从服务器复制功能
    stop slave;
    

    再执行

    -- 启动从服务器复制功能
    start slave; 
    
  6. 显示从库状态, 执行以下SQL:

    -- 显示从库状态
    show slave status;
    
  7. 检查查询结果,主要看下面几个

    • Slave_IO_Running: Yes
      此状态必须YES
    • Slave_SQL_Running: Yes
      此状态必须YES

    这里Slave_IO_Running可能为Connecting,主要有下面几个错误导致:

    • 网络不通,关闭主库防火墙
    • 密码不对
    • pos不对
  8. 测试
    读者自行测试即可,我这里测试是没问题的,主库插入数据,从库就会同步。

建库脚本

我这里使用了3个数据库:db1, db2, db3

  • db1.sql
