Q & A

Q: 網站轉址到 http://class.ruten.com.tw/user/index00.php?s=missing007 (露天賣場) 出現錯誤

A：這是因為設定 Redirect Path 時，系統會在轉址位址的末碼最後加上／，有些網站對於這樣的 URL 會出現頁面顯示錯誤。

解決方法是，在 Redirect Path 的 URL 最後加上＆試試。

Q: 如何修改網站的 Apache 參數

A：比如 Gallery2 安裝時，必須設定 PHP 參數

session.save_path "/var/www/clients/client1/webXX/php_session_tmp"

方法:

1. 以 admin 登入，Sites > 選擇網站 > Domain > PHP = Mod-PHP
2. 以 admin 登入，Sites > 選擇網站 > Options > Apache Directives
   php_admin_value session.save_path "/var/www/clients/client1/webXX/php_session_tmp"
3. 等 1-2 分後設定會套用

A：編輯 /etc/pure-ftpd/pure-ftpd.conf

PassivePortRange          40110 40210

重啟服務 pure-ftpd

# service pure-ftpd stop

變更網路防火的規則

將 Port 40110-40210 轉送到主機內部 IP

Q: 服務 pop3 & imap 出現 offline

Q： Limits 內的 main template 與 additional template 用法

A：
1. 狀況描述：

mail template)

• web domain 數量限制：2

additional template)

• web domain 數量限制：5

當 Client/Reseller 選擇了 main template 及 additional template 時，實際 web domain 數量限制為 7。

2. 名詞關聯

• master template -> main template
• addon template -> additional template
   

3. 如果 master template 選擇 Custom，則會套用頁面下方的設定參數。

Q：什麼是 PHP Options

A：原文說明如下：

PHP Options: Specify which PHP modes should be available for the client when he creates/modifies a web
site. The following four modes are available: Fast-CGI, CGI, Mod-PHP, SuPHP.

‧ Fast-CGI:
Advantages:
‧ Scripts will be executed with user privileges of the web site;
‧ More than one PHP version can be run as FastCGI;
‧ Might be better in speed compared to CGI and suPHP.
Disadvantages:
‧ php.ini values cannot be changed via PHP scripts, vhost files, .htaccess files. But it is possible to
use the Custom php.ini settings field on the Options tab of a web site in ISPConfig to
specify custom php.ini settings (see chapter 4.6.1.1).

‧ CGI:
Advantages:
‧ Scripts will be executed with user privileges of the web site;
‧ More than one PHP version can be run as CGI.
Disadvantages:
‧ CGI might use a little more memory (RAM) - therefore, it's not recommended to run PHP as CGI on
slow virtual servers;
‧ php.ini values cannot be changed via PHP scripts, vhost files, .htaccess files. But it is possible to
use the Custom php.ini settings field on the Options tab of a web site in ISPConfig to
specify custom php.ini settings (see chapter 4.6.1.1).

‧ Mod-PHP:
Advantages:
‧ Speed;
‧ Needs less memory (RAM) than CGI;
‧ php.ini values can be changed via PHP scripts, vhost files, .htaccess files.
Disadvantages:
‧ Scripts are being executed with Apache privileges, which might lead to some security related problems;
‧ Only one version of PHP can be installed as Apache module;
‧ You cannot use the Custom php.ini settings field on the Options tab of a web site in
ISPConfig to specify custom php.ini settings (see chapter 4.6.1.1).

‧ SuPHP:
Advantages:
‧ Scripts will be executed with user privileges of the web site;
‧ Each vhost can have its own php.ini file;
‧ Needs less memory (RAM) than CGI;
‧ More than one PHP version can be run as suPHP.
Disadvantages:
‧ php.ini values cannot be changed via PHP scripts, vhost files, .htaccess files. But it is possible to
use the Custom php.ini settings field on the Options tab of a web site in ISPConfig to
specify custom php.ini settings (see chapter 4.6.1.1);
‧ SuPHP might be a little slower than mod_php.

‧ Recommendations:
‧ High-Traffic Web Sites: Fast-CGI + suExec
‧ Low-Traffic Web Sites: CGI + suExec or SuPHP
