1 访问 nginx 官网下载页面：http://nginx.org/download/
如图下载最新版本，点击鼠标右键，复制下载链接

2 在 linux 系统合适目录下下载：wget http://nginx.org/download/nginx-1.9.9.tar.gz
解压：tar xvf nginx-1.9.9.tar.gz

3 进入上面解压后的目录： cd nginx-1.9.9
一气呵成安装相关依赖：yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
配置，编译和安装三连击：./configure && make && make install
查看软件版本：./nginx -v

1. 安装 gcc gcc-c++(如新环境, 未安装请先安装)
   $ yum install -y gcc gcc-c++
2. 安装 wget
   $ yum -y install wget
3. 安装 PCRE 库
   $ cd /usr/local/
   $ wget https://sourceforge.net/proje…
   $ tar -zxvf pcre-8.43.tar.gz
   $ cd pcre-8.43
   $ ./configure
   $ make && make install
   如果报错:
   在 linux 中执行 wget 命令提示 -bash: wget: command not found
   解决办法 yum -y install wget
4. 安装 SSL 库
   $ cd /usr/local/
   $ wget http://www.openssl.org/source…
   $ tar -zxvf openssl-1.0.1j.tar.gz
   $ cd openssl-1.0.1j
   $ ./config
   $ make && make install
5. 安装 zlib 库
   $ cd /usr/local/
   $ wget http://zlib.net/zlib-1.2.11.t…
   $ tar -zxvf zlib-1.2.11.tar.gz
   $ cd zlib-1.2.11
   $ ./configure
   $ make && make install
6. 安装 nginx
   $ cd /usr/local/
   $ wget http://nginx.org/download/ngi…
   $ tar -zxvf nginx-1.9.9.tar.gz
   $ cd nginx-1.9.9
   $ ./configure
   $ make && make install
7. 启动 nginx
   /usr/local/nginx/sbin/nginx

8. 配置

      # access_log off;
       }
       access_log off;
     }
   
   }

   检查配置文件 nginx.conf 的正确性命令：
   [root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

9. Nginx 其他命令
   /usr/local/nginx/sbin/nginx -s reload # 重新载入配置文件
   /usr/local/nginx/sbin/nginx -s reopen # 重启 Nginx
   /usr/local/nginx/sbin/nginx -s stop # 停止 Nginx
