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
# cat /etc/issue
Red Hat Enterprise Linux Server release 6.3 (Santiago)
Kernel \r on an \m
# nginx -v
nginx version: nginx/1.8.0二、配置安装环境
###为简化安装及配置，此处关闭了防火墙，生产环境建议开启
# service iptables stop
# chkconfig iptables off
# vi /etc/selinux/config
SELINUX=disabled
###创建用户及组
#groupadd -r nginx
#useradd -s /sbin/nologin -g nginx -r nginx
###安装环境依赖包 http://nginx.org/en/linux_packages.html
# yum install pcre-devel zlib-devel openssl openssl-devel gcc gcc-c++三、编译及安装Nginx
# cd /tmp/
# tar -xvf nginx-1.8.0.tar.gz
# cd /nginx-1.8.0
# ./configure \
--prefix=/etc/nginx \
--sbin-path=/usr/sbin/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx.pid \
--lock-path=/var/run/nginx.lock \
--http-client-body-temp-path=/var/cache/nginx/client_temp \
--http-proxy-temp-path=/var/cache/nginx/proxy_temp \
--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp \
--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp \
--http-scgi-temp-path=/var/cache/nginx/scgi_temp \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_stub_status_module \

###如果apache httpd服务启动，建议先停止或更改端口号
# service httpd stop
# 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
root 33412 1 0 10:18 ? 00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=<path> option.
### 以上2个错误，请安装相应的依赖包，见本文第二部分：配置安装环境
# /usr/sbin/nginx
nginx: [emerg] getpwnam("nginx") failed
### 需要创建nginx用户组及用户
# /usr/sbin/nginx
nginx: [emerg] mkdir() "/var/cache/nginx/client_temp" failed (2: No such file or directory)
### 需要创建对应的目录
