Nginx 配置虚拟主机

阅读本文需要安装Nginx

一 什么是配置虚拟主机

就是在一台服务器启动多个网站

二 通过端口区分虚拟主机

复制一份静态页面

　　cd /usr/local/nginx

　　cp -r html html81

修改部分内容以示区分

　　vim /usr/local/nginx/html81/index.html

查看配置文件

　　more /usr/local/nginx/conf/nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

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

        #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
        #
        #location ~ .php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ .php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    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;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

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

}

可以通过配置多个server来配置多个虚拟主机

添加虚拟主机 将下面配置拷贝进去(与原有的server节点同级)

　　vim /usr/local/nginx/conf/nginx.conf

    server {
        listen       81;
        server_name  localhost;

        location / {
            root   html81;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

进入sbin目录

　　cd /usr/local/nginx/sbin

开机状态刷新配置文件

　　./nginx -s reload

三 通过域名区分虚拟主机

域名: 域名就是网站

DNS服务器: 把域名解析为IP地址 保存的就是域名和IP的映射关系

注意: 一个域名对应一个IP地址 一个IP地址可以被多个域名绑定

这里我准备了2个域名

www.hb218.cn　　www.hdcpa.cn

在阿里云上购买的 只有3-5天的使用期(可以续费) 总共花了2个大洋 

买好域名之后需要在阿里云控制台 -> 云解析DNS -> 配置2个域名指向同一台nginx服务器(IP)

这里赞一下 马爸爸的阿里云平台啥都有 挺方便的

复制一份显示www.hb218.cn的静态页面

　　cd /usr/local/nginx

　　cp -r html html-hb218

修改部分内容以示区分

　　vim /usr/local/nginx/html-hb218/index.html

复制一份显示www.hdcpa.cn的静态页面

　　cd /usr/local/nginx

　　cp -r html html-hdcpa

修改部分内容以示区分

　　vim /usr/local/nginx/html-hdcpa/index.html

查看配置文件
　　more /usr/local/nginx/conf/nginx.conf

        location / {
            root   html-hb218;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {

        location = /50x.html {
            root   html;
        }
    }

进入sbin目录

　　cd /usr/local/nginx/sbin

开机状态刷新配置文件

　　./nginx -s reload

大功告成 浏览器分别访问www.hb218.cn　　www.hdcpa.cn
