Unknown collation: 'utf8mb4_unicode_ci'

日前给一个政府机关做个小的门户网站,用的是wordpress+主题开发,部署时发现导入数据库sql文本时出现Unknown collation: 'utf8mb4_unicode_ci'的错误,查了下原因:


I had the same issue as all of our servers run older versions of MySQL. This can be solved by running a PHP script. Save this code to a file and run it entering the database name, user and password and it'll change the collation from utf8mb4/utf8mb4_unicode_ci to utf8/utf8_general_ci


原因就是MySql的版本太老了,解决方法就是把
utf8mb4/utf8mb4_unicode_ci
替换成
utf8/utf8_general_ci


MySql版本不够,相信php的版本也没会够,三条黑线|||
