nginx配置虚拟主机

nginx 是一个小巧高效的 web 服务器，由俄罗斯程序员 Igor Sysoev 开发，nginx 虽然体积小，但功能一点也不弱，能和其他的 web 服务器一样支持 virtual hosting，即一个IP对应多个域名以支持多站点访问，就像一个IP对应一个站点一样，所以是”虚拟”的。

这里以配置2个站点（2个域名）为例，n 个站点可以相应增加调整，假设：

IP地址: 202.55.1.100
域名1 ysy1.com 放在 /www/ysy1
域名2 ysy22.com 放在 /www/ysy2

配置 nginx virtual hosting 的基本思路和步骤如下：

把2个站点 ysy1.com, ysy2.com 放到 nginx 可以访问的目录 /www/
给每个站点分别创建一个 nginx 配置文件 ysy1.com.conf，ysy2.com.conf, 并把配置文件放到 /etc/nginx/vhosts/
然后在 /etc/nginx.conf 里面加一句 include 把步骤2创建的配置文件全部包含进来（用 * 号）
重启 nginx

具体步骤：

1、在 /usr/local/etc/nginx 下创建 vhosts 目录

mkdir /etc/nginx/vhosts

2、在 /usr/local/etc/nginx/vhosts/ 里创建一个名字为 ysy1.com.conf 的文件，把以下内容拷进去

server {
        listen  80;#端口要和nginx端口一样，我的由8080默认端口改到80
        server_name ysy1.com www.ysy1.com;

        #access_log  /www/access_ysy1.log;

        location / {
            root   /www/ysy1.com;＃放置访问文件的目录，
            index  index.php index.html index.htm;＃访问文件的检索顺序
        }

        # error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;  ＃随便，这里我没有设置
        }

       # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        location ~ .php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /www/ysy1.com/$fastcgi_script_name;＃fastcgi需要配置
            include        fastcgi_params;
        }
        location ~ /.ht {
            deny  all;
        }
}

3、在 /usr/local/etc/nginx/vhosts/ 里创建一个名字为 ysy2.com.conf 的文件，把上边内容拷进去，将所有ysy1改称ysy2

4、打开 /usr/local/etc/nginix.conf 文件，在相应位置加入 include 把以上2个文件包含进来

user  www www;
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  /usr/local/Cellar/nginx/1.6.2/html$fastcgi_script_name;
            include        /usr/local/etc/nginx/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;
    #    }
    #}


    #include all vhosts
118     include /usr/local/etc/nginx/vhosts/*.conf;
}

5、建立nginx对应的访问目录及文件

sudo mkdir /www/ysy1.com/
vim /www/ysy1.com/index.php

index.php内部调用phpinfo(); 

6，修改hosts配置，重启 Nginx

sudo vim /etc/hosts

cat /etc/hosts
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1    localhost
255.255.255.255    broadcasthost
::1             localhost 
fe80::1%lo0    localhost
127.0.0.1       ysy1.com
127.0.0.1       ysy2.com
127.0.0.1       www.ysy1.com #访问什么配什么，与conf配置文件无关
127.0.0.1       www.ysy2.com
