Linux下安装Nginx并配置一个图片服务器

首先到Nginx官网下载tar.gz格式的安装包，这里下载的是nginx-1.10.3版本，环境使用centos6的虚拟机

1、将安装包上传，解压，命令tar -xvf nginx-1.10.3.tar.gz；

2、自定义创建一个文件夹作为Nginx安装目录，这里在home下创建nginx文件夹；

3、在解压的文件夹（nginx-1.10.3）下执行./configure --prefix=/home/nginx 命令。
意思即配置安装环境，将会把Nginx安装到/home/nginx下；

若没有gcc，先安装
yum -y install gcc gcc-c++ autoconf automake make

若出现缺少依赖包则先安装依赖包，以下纯净centos mini版碰到的两个依赖包问题

出现上面这个执行 yum -y install pcre-devel 安装依赖，

出现这个yum install -y zlib-devel 安装依赖，

若还有其他依赖问题，根据缺少的文件提示安装相应的东西；

4、编译：在解压的文件夹下先后执行make 和 make install 命令

5、Nginx默认使用端口是80，这里直接先把Nginx端口改为8088，vi /home/nginx/conf/nginx.conf，修改server的端口，并配置一个图片服务器

}

server下listen的端口改为8088，并增加一个location配置，用于访问图片文件，这一串配置有#号在前面的注释掉的都可以删掉，免得看起来又长又乱。

6、启动命令： /home/nginx/sbin/nginx -c /home/nginx/conf/nginx.conf。
打开防火墙对应端口供访问，8088，当然也可以直接关了防火墙。
若修改了nginx.conf配置，则需要重启才生效，命令：/home/nginx/sbin/nginx -s reload

7、访问。
输入ifconfig命令查看虚拟机ip，测试：

在/home/images下放张图片，测试访问：
