nginx的使用配置
nginx为反向代理服务器，可以反向代理不同域名转向不同的具体服务器。可以用于负载压力或是同一台机器使用不同域名进行访问。
以下片段是服务器配置：

#proxy server 在这里配置一个代理名称，最重要的是server指向的地址。
如下：
upstream webvoc.com{
server 115.28.213.130:8080 weight=2;
}
名称为webvoc.com的域名指向了115.28.213.130:8080的实际地址。
weight=2向的反向代理权重，当多个负载服务器工作时，可以加大转向某个服务器的机率。
upstream www.webvoc.com{
server 115.28.213.130:8080 weight=2;
}
表明使用www.webvoc.com指向同一个网站。
1 server{ 2 listen 80; 3 server_name webvoc.com; 4 error_log /tmp/vm_err.log; 5 access_log /tmp/vm_access.log; 6 location /{ 7 proxy_pass http://webvoc.com; 8 client_max_body_size 10m; 9 client_body_buffer_size 128k;10 proxy_read_timeout 120;11 proxy_connect_timeout 120;12 proxy_buffer_size 32k;13 proxy_buffers 4 64k;14 proxy_busy_buffers_size 128k;15 proxy_headers_hash_bucket_size 128;16 proxy_temp_file_write_size 128k;17 proxy_set_header X-Real-IP $remote_addr;18 proxy_set_header X-Forwarded-For $remote_addr;19 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;20 }21 location ~ .(qqLogin|registerQQ|registerWeiBo).action$ {22 proxy_pass http://webvoc.com; 23 }24 25 location ~ .(oauth2_qq).jsp$ {26 proxy_pass http://webvoc.com;27 } 28 29 error_page 500 502 503 504 /50x.html;30 location = /50x.html 31 {32 root /usr/share/nginx/www;33 }34 35 #location /NginxStatus {36 37 # stub_status on;38 # access_log off;39 # auth_basic "NginxStatus";40 #}41 42 location ~* \.(gif|jpg|jpeg|questionStyle|kindeditor|fileupload)$ {43 44 proxy_pass http://webvoc.com;45 } 46 47 }
server:是一个完整的服务器转向规则说明：
listen：是要侦听的端口号，如果使用域名访问，这里可全部设置为80端口。
server_name：这个就是上面提到upstream后面的名字。一般情况下和域名相同，但是可以不一致。
这个nginx配置中，有一个站点为PHP站点，直接使用nginx作解析。配置代码如下：
1 server { 2 listen 8011; 3 server_name localhost; 4 5 #charset koi8-r; 6 7 #access_log logs/host.access.log main; 8 9 location / {10 root /usr/local/www;11 index index.php;12 }13 14 location /svn { 15 proxy_set_header Host $host; 16 proxy_set_header X-Real-IP $remote_addr; 17 proxy_set_header X-Forwarded-Proto https; 18 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 19 proxy_pass http://127.0.0.1:8099/svn/; 20 } 21 #error_page 404 /404.html;22 23 # redirect server error pages to the static page /50x.html24 #25 error_page 500 502 503 504 /50x.html;26 location = /50x.html {27 root /usr/local/www;28 }29 30 # proxy the PHP scripts to Apache listening on 127.0.0.1:8031 #32 #location ~ \.php$ {33 # proxy_pass http://127.0.0.1;34 #}35 36 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:900037 #38 location ~ \.php$ {39 root /usr/local/www;40 fastcgi_pass 127.0.0.1:9000;41 fastcgi_index index.php;42 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;43 include fastcgi_params;44 }45 46 # deny access to .htaccess files, if Apache‘s document root47 # concurs with nginx‘s one48 #49 #location ~ /\.ht {50 # deny all;51 #}52 }
