无法在 httpd | centos 7 中启用 mpm-event

无法在 httpd | centos 7 中启用 mpm-event

我对 mpm 等还不熟悉,所以请不要介意。我有一个 Web 服务器,上面运行着 8 个网站(基于 php)。我的 RAM 使用率超过 90%,交换使用率超过 80%。当我检查时

服务 httpd 状态

请求数量通常会反弹到 30k,而且我看到很多 httpd 进程。我尝试通过搜索谷歌并尝试这个来修复它解决方案我以为启用 php-fpm 和 mod_mpm_event 会减轻我的 RAM 和 SWAP 负载,但是没有奏效,网站仍然加载像这样而原来的网站看起来像这样。因此,我恢复了旧的配置。

我的配置:

00-mpm.conf

[root@csmsvr-lin-lv-02 conf.modules.d]# cat 00-mpm.conf

# one of the following LoadModule lines:

您提供的图像显示您没有正确设置 PHP 处理程序。您应该能够使用(在 00-base.conf 中):

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

然后确保以下内容未被注释:

LoadModule mpm_event_module modules/mod_mpm_event.so

最后你需要改变:

<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>

到:

ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/path/to/your/documentroot/$1
DirectoryIndex /index.php index.php

确保使用正确的/path/to/your/documentroot。此外,php-fpm 需要运行(并监听 127.0.0.1 端口 9000)才能正常工作。如果不工作,请查看 Apache 和 PHP-FPM 的日志。通常这些位于/var/log/httpd/var/log/php-fpm
