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 $proxy_add_x_forwarded_for; 19 proxy_pass http://127.0.0.1:8099/svn/; 20 } 21 #error_page 404 /404.html; 22 23 # redirect server error pages to the static page /50x.html 24 # 25 error_page 500 502 503 504 /50x.html; 26 location = /50x.html { 27 root /usr/local/www; 28 } 29 30 # proxy the PHP scripts to Apache listening on 127.0.0.1:80 31 # 32 #location ~ \.php$ { 33 # proxy_pass http://127.0.0.1; 34 #} 35 36 # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 37 # 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 root 47 # concurs with nginx's one 48 # 49 #location ~ /\.ht { 50 # deny all; 51 #} 52 }
