另, 對(duì)于Event Scheduler和Trigger還各有一小點(diǎn), 要了解到.


Event Scheduler在MHA環(huán)境下, 手動(dòng)在線切換時(shí), 會(huì)有如下信息提示, 要暫將Event Scheduler關(guān)閉.

Wed Sep 13 10:55:43 2017 - [error][/usr/local/share/perl5/MHA/MasterRotate.pm, ln161] We should not start online master switch when one of connections are running long updates on the current master(192.168.19.168(192.168.19.168:3306)). Currently 1 update thread(s) are running.

Details:

{'Time' => '147223','Command' => 'Daemon','db' => undef,'Id' => '117223','Info' => undef,'User' => 'event_scheduler','State' => 'Waiting on empty queue','Host' => 'localhost'}

Wed Sep 13 10:55:43 2017 - [error][/usr/local/share/perl5/MHA/ManagerUtil.pm, ln177] Got ERROR:  at /usr/local/bin/masterha_master_switch line 53.


Trigger不能建立在mysql數(shù)據(jù)庫上, 會(huì)有如下報(bào)錯(cuò).

ERROR 1465 (HY000): Triggers can not be created on system tables
