Nginx捕获所有主机作为前端到Apache对于ISPConfig 2在CentOS 5

Nginx将所有主机作为前端到Apache为ISPConfig 2在CentOS 5上

Nginx （发音为“引擎X”）是一种轻量级的高性能Web服务器/反向代理和电子邮件（IMAP / POP3）代理，根据类似BSD的许可证许可。 它运行于UNIX，GNU / Linux，BSD变体，Mac OS X，Solaris和Microsoft Windows。 Apache的表现一般也很好。 然而，在资源有限的环境中，Apache不一定能提供最佳性能或资源利用率。 减少Apache压力的“最佳实践”方法之一就是让更轻的Web服务器接管网站的静态文件（图像，javascript，css等）的服务，从而使服务动态内容到Apache。 本教程将介绍如何将Nginx设置为ISPConfig 2 On CentOS 5.x的前端到apache。

我不会保证这将为您工作！

配置ISPConfig 2

首先，您需要更改ISPConfig 2配置文件，如下所示：

cp -v /root/ispconfig/scripts/lib/config.lib.php /root/ispconfig/scripts/lib/config.lib.php.orig
 vi /root/ispconfig/scripts/lib/config.lib.php

查找行号1283并将端口80更改为8080：

$web_port = ":80";

$web_port = ":8080";

查找行号2088和2089，并将端口80更改为8080：

  $test_vhost = "\n".'<virtualhost 10.0.0.1:80="">
ServerName www.test.tld:80
ServerAdmin webmaster@test.tld
DocumentRoot /home
'.$web_httpd_include.'
</virtualhost>';

  $test_vhost = "\n".'<virtualhost 10.0.0.1:8080="">
ServerName www.test.tld:8080
ServerAdmin webmaster@test.tld
DocumentRoot /home
'.$web_httpd_include.'
</virtualhost>';

如果你喜欢使用更简单的方法：

sed -ie 's/:80/:8080/g' /root/ispconfig/scripts/lib/config.lib.php

配置Apache

将Apache中的默认监听端口从80更改为8080。

vi /etc/httpd/conf/httpd.conf

Listen 80
UseCanonicalName Off

Listen 8080
UseCanonicalName On

安装Nginx

要安装nginx Web服务器：

yum install httpd-devel pcre perl pcre-devel zlib zlib-devel
 cd /tmp
 wget http://download.fedora.redhat.com/pub/epel/5/i386/nginx-0.6.39-5.el5.i386.rpm
 rpm -ivh nginx-0.6.39-5.el5.i386.rpm

注意：如果你喜欢安装最新版本的nginx，请查看此链接： 安装Nginx On CentOS 5.5使用SSL，PCRE，GeoIP，Zlib，Gzip和DAV支持

现在，您必须配置nginx。

vi /etc/nginx/nginx.conf

	}
	include /etc/nginx/conf.d/*.conf;
}

重要提示：请勿忘记在此配置文件中替换您的Apache服务器的IP ADDRESS。

重新启动所需服务，享受！

重新启动ISPConfig和Apache服务并启动nginx服务。

service httpd restart
 service ispconfig_server restart 
 service nginx start

测试

首先检查虚拟主机ispconfig文件：

cat /etc/httpd/conf/vhosts/Vhosts_ispconfig.conf

它必须看起来像：

######################################
# Vhost: www.example.com:8080
######################################
#
#
<virtualhost xxx.xxx.xxx.xxx:8080="">ServerName www.example.com:8080
ServerAdmin info@example.com
DocumentRoot /var/www/web100/web
...
</virtualhost>

其次，检查nginx日志和错误文件。

tail -f /var/log/nginx/access.log
 tail -f /var/log/nginx/error.log

如果需要，重新启动服务器。
