301 在 Ubuntu/Codeigniter4/Wordpress 上使用 htaccess 将 blog.example.com 重定向到 www.example.com/blog

Question

我有一个博客当前托管在我的子域上，我想将其移动到 /blog 子目录。主网站使用CodeIgniter4框架，博客使用Wordpress。它托管在使用 Ubuntu 的 Apache 服务器上。我可以将 blog.example.com 根目录重定向到 www.example.com/blog，但无法将 blog.example.com/123 重定向到 www.example.com/blog/123

这是网站的 .htaccess 文件（我添加的行是

RewriteCond $1 !^(index\.php|blog)

，但我包含了文件的主要部分以供参考：

# Turning on the rewrite engine is necessary for the following rules and features.
# FollowSymLinks must be enabled for this to work.
<IfModule mod_rewrite.c>
    Options +FollowSymlinks
    RewriteEngine On

    # If you installed CodeIgniter in a subfolder, you will need to
    # change the following line to match the subfolder you need.
    # http://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewritebase
    # RewriteBase /

    # Redirect Trailing Slashes...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Rewrite "www.example.com -> example.com"
    RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
    RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]

    # Checks to see if the user is attempting to access a valid file,
    # such as an image or css document, if this isn't true it sends the
    # request to the front controller, index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond $1 !^(index\.php|blog)
    RewriteRule ^([\s\S]*)$ index.php/$1 [L,NC,QSA]

    # Ensure Authorization header is passed along
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

这是博客的htaccess：

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

RewriteCond %{HTTP_HOST} ^blog\.example\.com
RewriteRule ^(.*)$ https://www.example.com/blog/$1 [R=301]

这是 www.example.com 的 Apache 配置文件：

<VirtualHost *:80>
     ServerAdmin [email protected]
     ServerName www.example.com
     ServerAlias www.example.com

     Protocols h2 http/1.1

     DocumentRoot /var/www/example-website/public

     <Directory /var/www/example-website/public>
          SetEnv website
          Options -Indexes +FollowSymLinks
          AllowOverride All
          Require all granted
     </Directory>

     Alias /blog "/var/www/example-blog/public_html"

     <Directory "/var/www/example-blog/public_html">
          SetEnv blog
          Options -Indexes +FollowSymLinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog /var/www/example-website/writable/logs/errors.log
     CustomLog /var/www/example-website/writable/logs/access.log combined env=website
     CustomLog /var/www/example-blog/public_html/wp-content/access.log combined env=blog

     RewriteEngine on
     RewriteCond %{SERVER_NAME} =www.example.com
     RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

作为参考，这里是 certbot 生成的 HTTPS 配置文件：

<IfModule mod_ssl.c>
<VirtualHost *:443>
     ServerAdmin [email protected]
     ServerName www.example.com
     ServerAlias www.example.com

     Protocols h2 http/1.1

     Alias /blog "/var/www/example-blog/public_html"

     <Directory "/var/www/example-blog/public_html">
          SetEnv blog
          Options -Indexes +FollowSymLinks
          AllowOverride All
          Require all granted
     </Directory>

     DocumentRoot /var/www/example-website/public

     <Directory /var/www/example-website/public>
          Options -Indexes +FollowSymLinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog /var/www/example-website/writable/logs/errors.log
     CustomLog /var/www/example-website/writable/logs/access.log combined env=website
     CustomLog /var/www/example-blog/public_html/wp-content/access.log combined env=blog

     RewriteEngine on
# Some rewrite rules in this file were disabled on your HTTPS site,
# because they have the potential to create redirection loops.

#      RewriteCond %{SERVER_NAME} =www.example.com
#      RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/www.example.com-0001/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/www.example.com-0001/privkey.pem
</VirtualHost>
</IfModule>

另外，与配置文件相关，有没有办法为博客提供单独的ErrorLog？

问题是博客 htaccess 文件。您需要将重写条件置于 WordPress 添加的指令上方。这是应该如何更新：

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^blog\.example\.com
RewriteRule (.*) https://www.example.com/blog/$1 [R=301,L]
</IfModule>

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
