最近在iXWebHosting的虚拟主机上安装WordPress，遇到两个问题。这里跟大家分享一下解决方法。

只能安装到子目录的问题

使用iXWebHosting提供的cPanel后台的EasyApps Collection直接安装应用程序WordPress的时候，安装位置必须输入一个目录名，也就是说，WordPress必须安装到一个网站的某个目录中，而我是想直接安装到该网站的根目录下。

只能折衷一下：随便输入一个目录，如输入/wordpress，然后一步一步安装完成。

这时候使用http://domain/wordpress登录安装好的WordPress，进入Generate Setting，把博客地址改成直接的根目录地址：http://domain/。

保存，OK，现在不能访问了（因为根目录下根本没有/wp-admin/）。

现在进入cPanel的File Manager，全选/domain/wordpress下的所有文件，Move到/domain/中，确定，等待进度完成。

再回到刚才无法访问的页面，OK，完成！

中文乱码

安装好WordPress以后，发现在文章中输入的中文字符，一保存就都变成了问号。

查了若干资料，找到一份iXWebHosting提供的官方资料，是MySQL默认编码的问题，MySQL新建数据库的时候，没有指定编码，因此使用了默认的latin1（冰岛语）编码。官方给出的建议是登录cPanel后台的PHPAdmin，手动逐一讲所有编码应用为latin1的表和字段修改成utf8_unicode_ci。

曾经尝试修改过一次，问题确实解决了，但是，表和字段，一共有六十几个地方需要修改。真的很繁琐。再次提供一份SQL语句，从PHPAdmin中可以直接运行SQL进行修改全部。不过这是针对WordPress 2.9的数据库。不知道其他版本或者以后的新版本数据库结构是否会发生改变。

我对MySQL的语法不太懂，所以使用了这样的笨方法，应该有办法可以进行表和字段的遍历，然后替换这样子的。希望有熟悉MySQL的高手分享一份更好的SQL代码。
