Install, compile and install Nginx under Linux 6-PHP Tutorial-php.cn

Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP服务器。在高连接并发的情况下，Nginx是Apache服务器不错的替代品：Nginx在美国是做虚拟主机生意的老板们经常选择的软件平台之一。能够支持高达50,000个并发连接数的响应，而且内存开销极小。这也是Nginx广受欢迎的重要原因。本文演示了基于Linux 6下编译安装Nginx，供大家参考。

一、安装环境

<code><span># cat /etc/issue</span>
Red Hat Enterprise Linux Server release <span>6.3</span> (Santiago)
Kernel \r <span><span>on</span><span>an</span> \<span>m</span></span><span># nginx -v</span>
nginx <span>version</span>: nginx/<span>1.8</span><span>.0</span></code>

二、配置安装环境

<code><span>###为简化安装及配置，此处关闭了防火墙，生产环境建议开启</span><span># service iptables stop</span><span># chkconfig iptables off</span><span># vi /etc/selinux/config </span>
SELINUX=disabled

<span>###创建用户及组</span><span>#groupadd -r nginx</span><span>#useradd -s /sbin/nologin -g nginx -r nginx</span><span>###安装环境依赖包 http://nginx.org/en/linux_packages.html</span><span># yum install pcre-devel zlib-devel openssl openssl-devel gcc gcc-c++</span></code>

三、编译及安装Nginx

# tar -xvf nginx-1.8.0.tar.gz
# cd /nginx-1.8.0

# mkdir -p /var/cache/nginx/{client_temp,proxy_temp,fastcgi_temp,uwsgi_temp,scgi_temp}
# make && make install

###启动nginx
# /usr/sbin/nginx -c /etc/nginx/nginx.conf

# ps -ef|grep nginx|grep -v grep
