我已经使用我现有的数据库在 MySQL 服务器 5.2 上设置了 Master to Master Replication。我成功地将我的 Master 1 的数据复制到 Master 2，用户名为 replication。但是当我尝试连接到主控 2 时，我从主控 1 收到错误。这是它们的详细信息：

确保您可以从 Master 1 DB 的主机连接到 Master 2 的 MySQL 套接字，您可以通过 shell 命令验证您是否能够连接：

telnet master-2-ip MYSQLPORT //3306 is the default port for mysql

如果此命令成功（这意味着您没有收到“拒绝连接”），请尝试连接：

mysql -u user -p'password' -H host -P port

如果问题不是连接问题，则在 /var/log 下发布您的 mysql 日志可能会有所帮助。
