wwwありなしのリダイレクト

 

wwwありにする

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

 

 

wwwなしにする

# vi .htaccess


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

 

 

ドメイン変更時のリダイレクト

 

ALB配下の場合

ALB配下の場合はApache設定ファイルで設定するのが楽

 

www.example-old.net.conf

# vi /etc/httpd/conf.d/www.example-old.net.conf


<VirtualHost *:80>
  DocumentRoot /var/www/vhosts/www.example-old.net/httpdocs
  ServerName www.example-old.net
  ServerAlias example-old.net

  ## リダイレクトする
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^www\.example-old\.net
    RewriteRule ^(.*)?$ https://www.example-new.net$1 [R=301,L]
  </IfModule>

  <Directory "/var/www/vhosts/www.example-old.net/httpdocs">
    # 2.2系
    #AllowOverride All
    #Order allow,deny
    #Allow from all

    # 2.4系対策
    AllowOverride All
    Require all granted
  </Directory>

</VirtualHost>

 

www.example-new.net.conf

# vi /etc/httpd/conf.d/www.example-new.net.conf


<VirtualHost *:80>
  DocumentRoot /var/www/vhosts/www.example-new.net/httpdocs
  ServerName www.example-new.net
  ServerAlias example-new.net
  ErrorLog logs/www.example-new.net-error.log
  CustomLog logs/www.example-new-access.log elb-customlog env=!nolog

  ## ALB対策
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP:X-Forwarded-Port} !^443$
    RewriteCond %{HTTP_USER_AGENT} !^ELB-HealthChecker
    RewriteRule ^(.*)?$ https://www.example-new.net$1 [R=301,L]
  </IfModule>

  <Directory "/var/www/vhosts/www.example-new.net/httpdocs">
    # 2.2系
    #AllowOverride All
    #Order allow,deny
    #Allow from all

    # 2.4系対策
    AllowOverride All
    Require all granted
  </Directory>
</VirtualHost>

 

 

 

 

.htaccessでの対応

• example-old.com
• www.example-old.com

→ https://www.example-new.com

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^(example-oldl\.com)(:80)? [NC]
  RewriteCond %{HTTP_HOST} ^(www.example-old\.com)(:80)? [NC]
  RewriteRule .* https://www.example-new.com%{REQUEST_URI} [R=301,L]
</IfModule>
