我将服务器操作系统从CentOS 7更改为Ubuntu18.4服务器，复制了所有文件，安装了一个新的Apache Web服务器，导入了DB。网站主页工作几乎都正常，但一旦我点击一个页面，就会得到404错误。 版本信息： PHP 7.2.17-0ubuntu0.18.04.1 Apache/2.4.29 (Ubuntu)
我在谷歌上搜索了一番，唯一可以追踪的是.htaccess文件出错了，所以我试了下WordPress文件，但仍然没有成功：
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
仅在站点上调用/Dir或直接调用时才出错404：
root@joeldig:/etc# apachectl -M
