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,因它的稳定性、丰富的功能集、示例配置文件和低系统资源的消耗而闻名。2011年6月1日,nginx 1.0.4发布。Nginx是一款轻量级的Web 服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器,并在一个BSD-like 协议下发行。由俄罗斯的程序设计师Igor Sysoev所开发,供俄国大型的入口网站及搜索引擎Rambler(俄文:Рамблер)使用。其特点是占有内存少,并发能力强,事实上nginx的并发能力确实在同类型的网页服务器中表现较好,中国大陆使用nginx网站用户有:百度、新浪、网易、腾讯等。
Nginx
step1. Install Nginx
yum install -y pcre-devel zlib-devel gcc openssl-devel
useradd -M -s /sbin/nologin nginx
tar zxvf nginx-XXX -C /usr/local/
./configure -prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-md5=/usr/lib --with-sha1=/usr/lib --with-http_gzip_static_module
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin
nginx -v #check nginx version
step2. Use nginx running script to change nginx service status.
