Question

我正在尝试使用SQL语句在2台MySQL 5.5服务器上设置主 - 主复制，但它似乎没有工作。

我在IP地址192.168.0.20（服务器A）和192.168.0.5（服务器B）上有2个MySQL服务器。

在服务器A上，我运行以下SQL语句。

CHANGE MASTER TO MASTER_HOST='192.168.0.5',
MASTER_PORT=3306,
MASTER_USER='root',
MASTER_PASSWORD='password-here',
master_connect_retry=6000;

set global sql_log_bin=1;
set global server_id=1;
set auto_increment_increment=2;
set auto_increment_offset=1; 

start slave;

服务器A上的错误日志显示：

二进制日志未打开（server_errno = 1236）

好像你还没有开始你的主人的二进制日志。我建议你停止奴隶，然后执行slave reset然后通过将log-bin设置为要用于二进制日志的文件来打开主人的二进制日志。
