如何使用 htaccess 为整个网站设置维护模式

Question

我找到了 htaccess 禁用整个网站的代码（用于维护模式）：

Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !/offline.php$
RewriteRule .* /offline.php [R=307,L]

现在在我的 offline.php 页面中，我有一个指向 css 和 js 文件的链接，例如：

<link rel="stylesheet" href="include/css/error.css">
<script src="include/js/file.js"></script>

当我使用上面的代码设置维护模式时，加载了offline.php页面，但是没有css和js，如何允许加载这两个文件？

而且我认为禁用除我的 ip 之外的所有人的网站很有用，这样我可以更新网站，这可能吗？

Answer 1

如果您的根目录中还没有 .htaccess 文件 域，创建一个并添加以下代码。如果你已经有一个 .htaccess 文件，在所有内容前面添加以下代码 可能在里面

RewriteEngine On

# Add all the IP addresses of people that are helping in development
# and need to be able to get past the maintenance mode.
# One might call this the 'allow people list'
RewriteCond %{REMOTE_HOST} !^83\.101\.79\.62
RewriteCond %{REMOTE_HOST} !^91\.181\.207\.191

# Make sure the maintenance mode only applies to this domain
# Example: I am hosting different sites on my server
# which could be affected by these rules.
RewriteCond %{HTTP_HOST} ^nocreativity.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.nocreativity.com$

# This is the 'ignore file list'. It allows access to all
# files that are needed to display the maintenance mode page.
# Example: pages, css files, js files, images, anything.
# IMPORTANT: If you don't do this properly, visitors will end up with
# endless redirect loops in their browser.
RewriteCond %{REQUEST_URI} !/offline\.htm$
RewriteCond %{REQUEST_URI} !/css\/style\.css$
RewriteCond %{REQUEST_URI} !/images\/logo\.png$

# Rewrite whatever request is coming in to the maintenance mode page
# The R=302 tells browsers (and search engines) that this
# redirect is only temporarily.
# L stops any other rules below this from executing whenever somebody is redirected.
RewriteRule \.*$ /offline.htm [R=302,L]

Step1：在根目录下创建一个文件'.maintence'，如.htaccess

Step2：将这段代码放入文件中

  <?php $upgrading = time();?>

Step3：保存文件，然后你可以看到默认的维护信息'Briefifiable for scheduled maintenance。请稍后再查看。'。

如果您想拥有自己的警告消息，请执行以下操作：

创建一个“maintenance.php”文件并将其放置在您的 wp-content 目录中，wordpress 使用此文件在您设置的任何强制维护期间显示。

这是一个很好的答案，但这是其中的代码，以防链接失效：

RewriteEngine On

# Add all the IP addresses of people that are helping in development
# and need to be able to get past the maintenance mode.
# One might call this the 'allow people list'
RewriteCond %{REMOTE_HOST} !^83\.101\.79\.62
RewriteCond %{REMOTE_HOST} !^91\.181\.207\.191

# Make sure the maintenance mode only applies to this domain
# Example: I am hosting different sites on my server
# which could be affected by these rules.
RewriteCond %{HTTP_HOST} ^nocreativity.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.nocreativity.com$

# This is the 'ignore file list'. It allows access to all
# files that are needed to display the maintenance mode page.
# Example: pages, css files, js files, images, anything.
# IMPORTANT: If you don't do this properly, visitors will end up with
# endless redirect loops in their browser.
RewriteCond %{REQUEST_URI} !/offline\.htm$
RewriteCond %{REQUEST_URI} !/css\/style\.css$
RewriteCond %{REQUEST_URI} !/images\/logo\.png$

# Rewrite whatever request is coming in to the maintenance mode page
# The R=302 tells browsers (and search engines) that this
# redirect is only temporarily.
# L stops any other rules below this from executing whenever somebody is redirected.
RewriteRule \.*$ /offline.htm [R=302,L]
