MySQL Replication 遇到 Error 'You cannot 'ALTER' a log table if logging is enabled' on query. 修復

此篇有寫解法: MySQL replication Error 'You cannot 'ALTER' a log table if logging is enabled' on query

看來是 MySQL 的 show_query_log 的檢查造成的問題, 先關掉讓他執行過即可, 步驟如下:

1. SHOW SLAVE STATUS \G # 看問題是什麼
2. STOP SLAVE;
3. SET GLOBAL slow_query_log = 'OFF'; SET GLOBAL sql_log_bin = 0; # 先關掉
4. START SLAVE;
5. SHOW SLAVE STATUS \G # 看是否正常啟動了
6. SET GLOBAL slow_query_log = 'ON'; SET GLOBAL sql_log_bin = 1; # 改回來
7. 到此即完成
