这是数据库编码的问题，查了网上的一些资料，出现这个问题的原因在于，wordpress4.2版本之后升级了数据库，如果数据库是mysql5.5以上的互相导入没有问题，如果老网站是mysql5.5的，导入新网站是mysql5.5版本以下的，就会出现这个问题。
根据wordpress官方的解释，在导入数据库之前，只需要把utf8mb4编码转成utf-8就可以了，有两种方法可以替换数据库编码：
实践了一下，有效的解决办法如下：
一、替换代码
从老的数据库中导出的数据库文件，用ue等代码编辑器打开。
查找：utf8mb4_unicode_ci，全部替换为：utf8_general_ci
查找：utf8mb4 全部替换为 utf8
按照顺序完成上面的操作。保存。
二、修改文件
修改wordpress的配置文件wp-config.php
把define(‘DB_CHARSET’, ‘utf8mb4’);
改为define(‘DB_CHARSET’, ‘utf-8’);
完成之后，基本能解决问题了。 参考技术A mysql 初始化数据库报错

报错
[ERROR] --initialize specified but the data directory has files in it. Aborting.
解决方法 删除data 原因 ，可能是重复安装 mysql 导致 data文件夹下有文件
rm -rf /usr/local/mysql/data/*
报错
[ERROR] Too many arguments (first extra is ' ').
初始化命令有空格或者' '里面的命令未能识别
