1、下载安装
首先安装必要的库(nginx 中gzip模块需要 zlib 库,rewrite模块需要 pcre 库,ssl 功能需要openssl库)。选定/usr/local为安装目录,以下具体版本号根据实际改变。
(1)安装准备
yum install gcc-c++
yum install pcre pcre-devel
yum install zlib zlib-devel
yum install openssl openssl–devel
(2)安装Nginx
安装之前,最好检查一下是否已经安装有nginx

$   find -name nginx

如果系统已经安装了nginx,那么就先卸载

$   yum remove nginx

首先进入/usr/local目录

$   cd /usr/local

从官网下载最新版的nginx

$   wget http://nginx.org/download/nginx-1.7.4.tar.gz

解压nginx压缩包

$   tar -zxvf nginx-1.7.4.tar.gz

会产生一个nginx-1.7.4 目录,这时进入nginx-1.7.4目录

$   cd  nginx-1.7.4

接下来安装,使用–prefix参数指定nginx安装的目录,make、make install安装

$   ./configure  $默认安装在/usr/local/nginx   
$   make  
$   make install

如果没有报错,顺利完成后,最好看一下nginx的安装目录

$   whereis nginx

启动:
/usr/local/nginx/sbin/nginx
检查:
打开浏览器访问此机器的 IP,如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。
部分命令如下:
重启:
$ /usr/local/nginx/sbin/nginx –s reload
停止:
$ /usr/local/nginx/sbin/nginx –s stop
测试配置文件是否正常:
$ /usr/local/nginx/sbin/nginx –t
强制关闭:
$ pkill nginx
2、配置
(1)修改配置文件
/usr/local/nginx/conf/nginx.conf
(2)server配置
接收请求的服务器需要将不同的请求按规则转发到不同的后端服务器上,在 nginx 中我们可以通过构建虚拟主机(server)的概念来将这些不同的服务配置隔离。
server {
listen 80; #指定服务1端口
server_name localhost; #指定服务IP
root html;
index index.html index.htm;
}
如修改为:
server {
listen 80;
server_name host2;
root /data/www/html;
index index.html index.htm;
}

(3)其他配置
Localtion、静态文件映射等等,可以通过apollo进行配置,相关配置根据实际项目进行配置。实际项目用docker安装nginx,并映射配置后,完成配置。
3、docker安装nginx
(1)拉取镜像
docker pull nginx
(2)映射配置
#创建文件夹 mkdir -p /home/nginx
#新建文件(已经是经过修改的配置文件): cat > nginx.conf
