今天一个SHOPNC商城突然变慢，查看服务器情况，发现MYSQL占用181%CPU，然后查看PHP慢查询，发现这样的内容

[22-Nov-2016 20:55:41]  [pool www] pid 50624
script_filename = /home/xxxx/public_html/mobile/index.php
[0x00007fcc47bad470] query() /home/xxx/public_html/core/framework/db/mysqli.php:90

[0x00007fcc47bac978] run() /home/xxxx/public_html/mobile/index.php:26

这是第三方登陆用到的，然后我查看了 mb_user_token 这表，发现居然没有索引，把 token 这个字段加个索引，解决问题
