CentOS 编译安装 Nginx 1.10

•

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。

安装约定

nginx源码路径：/usr/local/src
nginx安装路径：/usr/local/nginx
nginx配置文件路径：/usr/local/nginx/conf/nginx.conf
nginx虚拟主机路径：/usr/local/nginx/conf/vhosts

源码包下载地址

http://nginx.org/en/download.html

下载源代码包

# cd /usr/local/src/
# wget http://nginx.org/download/nginx-1.10.x.tar.gz

安装gcc、make等

# yum -y install gcc gcc-c++ make

安装编译nginx所需的库

# yum -y install pcre pcre-devel zlib zlib-devel openssl openssl-devel

添加nginx用户和组

# groupadd -g 500 nginx
# useradd -u 500 -g nginx -c "Nginx web server" -d /var/lib/nginx -s /sbin/nologin nginx

安装nginx

# cd ..
# tar zxvf nginx-1.10.x.tar.gz
# cd nginx-1.10.x
# ./configure --prefix=/usr/local/nginx \
--user=nginx --group=nginx \
--with-http_ssl_module \
--with-http_v2_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-pcre \
--with-ipv6 \
--with-stream
# make
# make install

配置nginx启动脚本

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

启动nginx

# chmod +x /etc/init.d/nginx
# service nginx start

配置nginx开机启动

# chkconfig nginx on

设置nginx环境变量

# vim /etc/profile

在其文件末尾添加如下变量

export PATH=$PATH:/usr/local/nginx/sbin

或者用以下命令添加

# sed -i '/unset -f pathmunge/a\export PATH=$PATH:/usr/local/nginx/sbin' /etc/profile

运行如下命令使环境变量生效

# source /etc/profile
