主 - 主复制不起作用

Question

我配置了WAMP在不同机器上运行的两台服务器以进行主-主复制。我正在linksys为网络使用路由器。我创建了一个无线网络，但其中一个服务器盒没有，WIFI所以我使用电缆将其连接到路由器。配置好之后，好像一切正​​常，但是服务器之间好像没有作为slave相互连接。下面是服务器状态。

在 IP 地址为 192.168.1.102 的服务器 1 上运行以下查询，得到以下结果

SELECT user, host FROM mysql.user WHERE Repl_slave_priv = 'Y';

+-----------+-------------------------+
| User      | host                    |

| master    | 192.168.1.100           |
+-----------+-------------------------+

对于 IP 为 192.168.1.100 的服务器 2

 +-----------+-------------------------+
 | User      | host                    |
 +-----------+-------------------------+

 | master    | 192.168.1.102           |

Answer 1

在您的错误日志中：

[ERROR] Slave I/O: error connecting to master 'master@192.168.1.100:3306' - retry-time: 60  retries: 86400, Error_code: 2003

Error_code: 2003 : The error (2003) Can't connect to MySQL server on 'server' (10061) 表示网络连接被拒绝。您应该检查是否有 MySQL 服务器在运行，是否启用了网络连接，以及您指定的网络端口是否是服务器上配置的端口。

尝试使用您的“主”帐户从一台服务器连接到另一台服务器：

在 192.168.1.100 上：

mysql -h 192.168.1.102 -u master -p

在 192.168.1.102 上：

mysql -h 192.168.1.100 -u master -p

检查，您的防火墙，尝试ping和其他与网络通信有关的东西...

最大限度。
