Linux上搭建 Nginx图片服务

前言：在我们服务器中除了搭载web服务，可能还需要用到图片服务。由于个人原因，前期配置环境搭载了Apache Web服务，此次将使用Nginx搭建一个图片服务器

第一步，安装Nginx环境

• gcc 编译依赖环境

yum install gcc-c++

• PCRE Perl库（nginx的http模块使用pcre解析）

yum install -y pcre pcre-devel

• zlib nginx使用zlib对http包的内容进行gzip

yum install -y zlib zlib-devel

• openssl 常用的密钥和证书封装管理功能及SSL协议

yum install -y openssl openssl-devel

第二步，安装Nginx

• 到Nginx官网下载tar.gz格式的安装包 Nginx下载地址,以nginx-1.10.3版本为例

1. 将安装包上传（推荐个好用的FTP传输工具 Nginx下载地址 提取码: 72q2），解压，命令

tar -zxvf nginx-1.10.3.tar.gz

2. 自定义创建一个文件夹mkdir nginx作为Nginx安装目录，这里在home下创建nginx文件夹（注：不要将自定义nginx文件夹放在usr/local/ 下，否者编译会报错！！！）；
3. 在解压的文件夹（nginx-1.10.3）下执行以下 命令（如果抛出错误，请检查Nginx环境是否都安装成功）。

./configure --prefix=/home/nginx

4. 编译：在解压的文件夹下先后执行以下命令；

make & make install 

如果执行到这里没有出问题，就可以把压缩文件和解压目录删除掉了rm -rf /tar -zxvf nginx-1.10.3.tar.gz 和 rm -rf /home/nginx

5. Nginx默认使用端口是80，这里直接先把Nginx端口改为8888;

        location / {

        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
}

server下listen的端口改为8888，并增加一个location配置，用于访问图片文件;

6. 启动命令：

 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

打开防火墙对应端口供访问，8888，添加安全组规则，当然也可以直接关了防火墙。
例如：腾讯云

image

若修改了nginx.conf配置，则需要重启才生效，命令：

/usr/local/sbin/nginx -s reload

7. 访问。IP:8888
   image

8. 在/home/images下放张图片，测试访问：
   image

恭喜你，完成配置~
