Nginx实战（一） 虚拟主机

1、利用虚拟主机，不同为每个要运行的网站提供一台单独的Nginx服务器或单独运行一组Nginx进程。虚拟主机提供了在同一台服务器、同一组Nginx进程上运行多个网站的功能。

在Nginx配置文件nginx.conf中，一个最简化的虚拟主机配置代码如下

 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;        #}

基于IP的虚拟主机

可以在一块物理网卡上绑定多个lP地址。这样就能够在使用单一网卡的同一个服务器上运行多个基于IP的虚拟主机。设置IP别名也非常容易，只须配置系统上的网络接口，让它监听额外的lP地址。

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      192.168.0.104:8080;    server_name swac.5iss.cn;    root B:\\apache-tomcat-7.0.56\\webapps\\ROOT;   }      server {    listen      192.168.0.104:8090;    server_name netitcast.com;    root B:\\apache-tomcat-7.0.57\\webapps\\ROOT;   }    # 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;    #    }    #}}

基于域名的虚拟主机

基于域名的虚拟主机是最常见的一种虚拟主机。只需配置你的DNS服务器，将每个主机名映射到正确的lP地址，然后配置Nginx服务器，令其识别不同的主机名就可以了。这种虚拟主机技术，使很多虚拟主机可以共享同一个lP地址，有效解决了lP地址不足的问题。所以，如果没有特殊要求使你必须用一个基于lP的虚拟主机，最好还是使用基于域名的虚拟主机。
编辑C:\windows\System32\driver\etc加入虚拟域名以便解析。

编辑内容如下：

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host


127.0.0.1       localhost  
127.0.0.1 netitcast.com
127.0.0.1 swac.5iss.cn

修改Nginx配置文件nginx.conf，添加虚拟域名支持

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    8080;    server_name swac.5iss.cn;    root B:\\apache-tomcat-7.0.56\\webapps\\ROOT;   }      server {    listen   8090;    server_name netitcast.com;    root B:\\apache-tomcat-7.0.57\\webapps\\ROOT;   }    # 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;    #    }    #}}

基于端口的虚拟主机

基于端口的虚拟主机配置，使用端口来区分，浏览器使用域名或ip地址:端口号访问。

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    8080;    server_name swac.5iss.cn;    root B:\\apache-tomcat-7.0.56\\webapps\\ROOT;   }      server {    listen   8090;    server_name netitcast.com;    root B:\\apache-tomcat-7.0.57\\webapps\\ROOT;   }    # 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;    #    }    #}}
