apache+fastcgi+fpm为什么需要suexec - apache + fastcgi + fpm Why is suexec required?

apache + fastcgi + fpm Why is suexec required?

所以我有以下工作虚拟主机：

<VirtualHost 192.168.128.20:80> 
        ServerName euclid.domain.tld 
        #LogLevel debug 
        ErrorLog /var/www/euclid/logs/error_log 
        SuexecUserGroup fastcgi www_euclid 
        FastCgiExternalServer /var/www/euclid/htdocs/cgi-bin -socket /var/run/php-fpm/euclid.sock -user fastcgi -group www_euclid 
        AddHandler php-fastcgi .php 
        Action php-fastcgi /cgi-bin 
        Alias /cgi-bin /var/www/euclid/htdocs/cgi-bin 
        <Location /cgi-bin> 
                Order Deny,Allow 
                Deny from All 
                # Prevent accessing this path directly 
                Allow from env=REDIRECT_STATUS 
                Options +ExecCGI +FollowSymLInks +SymLinksIfOwnerMatch 
        </Location> 
        DocumentRoot /var/www/euclid/htdocs 
        <Directory /var/www/euclid/htdocs> 
                AllowOverride all 
                Order allow,deny 
                Allow from all 
        </Directory> 
</VirtualHost>

我似乎不明白的是，为什么我需要同时拥有SuexecUserGroup fastcgi www_eucld和FastCgiExternalServer中的一个/两个带有-user fastcgi-group www_eUCLD标志。FPM启用了池，每个池都在自己的用户/组下运行。这是正确的，没有问题。如果我删除了SuexecUserGroup和/或-user-fastcgi-group www_eucld参数，我会得到以下错误，我不知道为什么。另外，fastcgi使用哪个uid和gid来访问套接字文件？它当然不是fastcgi:ww_eucld。

(13)Permission denied: FastCGI: failed to connect to server
"/var/www/euclid/htdocs/cgi-bin": connect() failed  FastCGI:
incomplete headers (0 bytes) received from server
"/var/www/euclid/htdocs/cgi-bin"

好的，我相信我已经弄清楚问题出在哪里了。简单的答案是：；mod_fastcgi糟透了。它陈旧、未经维护且记录不足。为什么在查找如何运行php-fpm时它不断出现，我无法理解。省省你自己的头痛，不要使用它！

真正的解决方案很简单：

<VirtualHost 192.168.128.20:80> 
        ServerName euclid.domain.tld 
        #LogLevel debug 
        ErrorLog /var/www/euclid/logs/error_log 
        <IfDefine PROXY>
                #If you want to use mod_proxy (Probably the best option)
                ProxyPassMatch ^/(.*'.php(/.*)?)$ fcgi://localhost:9000/var/www/euclid/htdocs/$1
        </IfDefine>
        <IfDefine FASTCGI_HANDLER>
                #If you want to use mod_fastcgi_handler (3rd party)
                AddHandler fcgi:/var/run/php-fpm-euclid.sock .php
        </IfDefine>

        DocumentRoot /var/www/euclid/htdocs 
        <Directory /var/www/euclid/htdocs> 
                AllowOverride all 
                Order allow,deny 
                Allow from all 
        </Directory> 
</VirtualHost>

您是偶然使用SELinux吗？我遇到了一个类似的问题，它是由SELinux安全策略引起的，该策略阻止Apache连接到Django的fastcgi套接字。运行setenforce Permissive允许它工作。
