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
1 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
1 server { 2 listen 80;#端口要和nginx端口一样，我的由8080默认端口改到80 3 server_name ysy1.com www.ysy1.com; 4 5 #access_log /www/access_ysy1.log; 6 7 location / { 8 root /www/ysy1.com;＃放置访问文件的目录， 9 index index.php index.html index.htm;＃访问文件的检索顺序 10 } 11 12 # error_page 500 502 503 504 /50x.html; 13 location = /50x.html { 14 root html; ＃随便，这里我没有设置 15 } 16 17 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 18 location ~ \.php$ { 19 fastcgi_pass 127.0.0.1:9000; 20 fastcgi_index index.php; 21 fastcgi_param SCRIPT_FILENAME /www/ysy1.com/$fastcgi_script_name;＃fastcgi需要配置 22 include fastcgi_params; 23 } 24 location ~ /\.ht { 25 deny all; 26 } 27 }
3、在 /usr/local/etc/nginx/vhosts/ 里创建一个名字为 ysy2.com.conf 的文件，把上边内容拷进去，将所有ysy1改称ysy2
4、打开 /usr/local/etc/nginix.conf 文件，在相应位置加入 include 把以上2个文件包含进来
1 user www www; 2 worker_processes 1; 3 4 #error_log logs/error.log; 5 #error_log logs/error.log notice; 6 #error_log logs/error.log info; 7 8 #pid logs/nginx.pid; 9 10 11 events { 12 worker_connections 1024; 13 } 14 15 16 http { 17 include mime.types; 18 default_type application/octet-stream; 19 20 #log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘ 21 # ‘$status $body_bytes_sent "$http_referer" ‘ 22 # ‘"$http_user_agent" "$http_x_forwarded_for"‘; 23 24 #access_log logs/access.log main; 25 26 sendfile on; 27 #tcp_nopush on; 28 29 #keepalive_timeout 0; 30 keepalive_timeout 65; 31 32 #gzip on; 33 34 server { 35 listen 80; 36 server_name localhost; 37 38 #charset koi8-r; 39 40 #access_log logs/host.access.log main; 41 42 location / { 43 root html; 44 index index.html index.htm; 45 } 46 47 #error_page 404 /404.html; 48 49 # redirect server error pages to the static page /50x.html 50 # 51 error_page 500 502 503 504 /50x.html; 52 location = /50x.html { 53 root html; 54 } 55 56 # proxy the PHP scripts to Apache listening on 127.0.0.1:80 57 # 58 #location ~ \.php$ { 59 # proxy_pass http://127.0.0.1; 60 #} 61 62 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 63 # 64 location ~ \.php$ { 65 root html; 66 fastcgi_pass 127.0.0.1:9000; 67 fastcgi_index index.php; 68 fastcgi_param SCRIPT_FILENAME /usr/local/Cellar/nginx/1.6.2/html$fastcgi_script_name; 69 include /usr/local/etc/nginx/fastcgi_params; 70 } 71 72 # deny access to .htaccess files, if Apache‘s document root 73 # concurs with nginx‘s one 74 # 75 #location ~ /\.ht { 76 # deny all; 77 #} 78 } 79 80 81 # another virtual host using mix of IP-, name-, and port-based configuration 82 # 83 #server { 84 # listen 8000; 85 # listen somename:8080; 86 # server_name somename alias another.alias; 87 88 # location / { 89 # root html; 90 # index index.html index.htm; 91 # } 92 #} 93 94 95 # HTTPS server 96 # 97 #server { 98 # listen 443 ssl; 99 # server_name localhost; 100 101 # ssl_certificate cert.pem; 102 # ssl_certificate_key cert.key; 103 104 # ssl_session_cache shared:SSL:1m; 105 # ssl_session_timeout 5m; 106 107 # ssl_ciphers HIGH:!aNULL:!MD5; 108 # ssl_prefer_server_ciphers on; 109 110 # location / { 111 # root html; 112 # index index.html index.htm; 113 # } 114 #} 115 116 117 #include all vhosts 118 include /usr/local/etc/nginx/vhosts/*.conf; 119 }
5、建立nginx对应的访问目录及文件
1 sudo mkdir /www/ysy1.com/ 2 vim /www/ysy1.com/index.php
index.php内部调用phpinfo();
6，修改hosts配置，重启 Nginx
1 sudo vim /etc/hosts
1 cat /etc/hosts 2 ## 3 # Host Database 4 # 5 # localhost is used to configure the loopback interface 6 # when the system is booting. Do not change this entry. 7 ## 8 127.0.0.1 localhost 9 255.255.255.255 broadcasthost 10 ::1 localhost 11 fe80::1%lo0 localhost 12 127.0.0.1 ysy1.com 13 127.0.0.1 ysy2.com 14 127.0.0.1 www.ysy1.com #访问什么配什么，与conf配置文件无关 15 127.0.0.1 www.ysy2.com
