Apache 2.2 升級到 2.4 的 Conf 調整修復

Debian jessie 將 Apache 改成 2.4 的版本, 然後就全部爛掉了~ 設定檔需要做大幅度的修改, 做作筆記.

• apache2-mpm-event - transitional event MPM package for apache2
• apache2-mpm-itk - transitional itk MPM package for apache2
• apache2-mpm-prefork - transitional prefork MPM package for apache2
• apache2-mpm-worker - transitional worker MPM package for apache2

Apache 2.2 升級到 2.4 的 Conf 調整修復

參考網頁

• Upgrading to 2.4 from 2.2 - Apache HTTP Server
• Overview of new features in Apache HTTP Server 2.4 - Apache HTTP Server
• prefork - Apache HTTP Server
• worker - Apache HTTP Server
• event - Apache HTTP Server
• Authentication and Authorization - Apache HTTP Server
• Module Index - Apache HTTP Server

由  Debian wheezy => testing, 就會遇到 apache 2.2 升級到 2.4, 於是就出現下述錯誤訊息:

403 Forbidden
authz_core:error] [pid 6719] [client 122.96.59.104:57926] AH01630: client denied by server configuration
[Sun Nov 24 01:56:51.624289 2013] [authz_core:error] [pid 7250] [client 192.168.1.191:59434] AH01630: client denied by server configuration: /var/wwww/index.php

註: 第一次升級遇到問題要馬上先解決掉問題, 可以考慮先試試看此招, 之後再看下面的詳細研究:

1. vim /etc/apache2/sites-enabled/0.conf # 內容如下
   

   <Directory /var/>
   Require all granted
   </Directory>

2. /etc/init.d/apache2 reload

下述是 Apache 2.2 VS Apache 2.4 的設定檔有哪些變更差異

1. Deny All
   • 2.2 configuration:
     • Order deny,allow
     • Deny from all
   • 2.4 configuration:
     • Require all denied
2. Allow All
   • 2.2 configuration:
     • Order allow,deny
     • Allow from all
   • 2.4 configuration:
     • Require all granted
3. Allow Host
   • 2.2 configuration:
     • Order Deny,Allow
     • Deny from all
     • Allow from example.org
   • 2.4 configuration:
     • Require host example.org
4. Directory 用 Require all granted
   

   <Directory /var/>
   Options FollowSymLinks
   AllowOverride None
   Require all granted
   </Directory>

5. FilesMatch 維持用 Order
   

   <FilesMatch ".+\.phps$">
   SetHandler application/x-httpd-php-source
   Order Deny,Allow
   Allow from all
   </FilesMatch>

找出有哪些需要設定需要修改:

1. cd /etc/apache2/sites-enabled/
2. grep -i deny *
3. grep -i "allow " *
4. grep -i "allow " * | grep -v '#'

哪邊有放 www 的, 就會需要打開 directory

<Directory /home/www/>
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
<Directory /var/> # 對整個開啟的話, 就跟 2.2 版一樣意思了.
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>

另外, 目錄裡面沒有放 index.html 而出現的 403 錯誤, 如下:

[Sun Nov 24 02:18:51.160249 2013] [autoindex:error] [pid 10541] [client 192.168.1.191:59786] AH01276: Cannot serve directory /var/www/css/: No matching DirectoryIndex (index.html,index.php,slideshow.xul,index.xul) found, and server-generated directory index forbidden by Options directive, referer: http://example.com/

加上下述:

<Directory /var/www/>
Options FollowSymLinks Indexes
Require all granted
</Directory>

PHP 出現的 Warning

PHP Warning:  date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the +date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone +identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/www/bin/a.php on line +11

上述設定 timezone 即可.

PHP 遇到另外的修改會有下述:

1. apt-get install php5-json # json 需要另外安裝
2. php5-curl 裡面的預設參數, 都要改2
   • -        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  1);
   • +        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);
