如何僅使用SQL語句設置MySQL 5.5複製？

Question

我想在2臺MySQL 5.5服務器上只使用SQL語句來設置master-master複製，但它似乎沒有工作。

我在IP地址192.168.0.20（服務器A）和192.168.0.5（服務器B）上有2個MySQL服務器。

在服務器A上，我運行以下SQL語句。

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; 

在服務器A的錯誤日誌顯示：

二進制日誌未打開（server_errno = 1236）

看來喲你還沒有開始你的主人的二進制日誌。我建議你停止從站，然後執行slave reset，然後通過將log-bin設置爲要用於二進制日誌的文件來打開主站的二進制日誌。
