可以参考如下的完整例子http://wiki.codemongers.com/NginxFullExample
#用户 用户组 user www www; #工作进程，根据硬件调整，有人说几核cpu，就配几个，我觉得可以多一点 worker_processes 5； #错误日志 error_log logs/error.log; #pid文件位置 pid logs/nginx.pid; worker_rlimit_nofile 8192; events { #工作进程的最大连接数量，根据硬件调整，和前面工作进程配合起来用，尽量大，但是别把cpu跑到100%就行 worker_connections 4096; } http { include conf/mime.types; #反向代理配置，可以打开proxy.conf看看 include /etc/nginx/proxy.conf; #fastcgi配置，可以打开fastcgi.conf看看 include /etc/nginx/fastcgi.conf; default_type application/octet-stream; #日志的格式 log_format main '$remote_addr - $remote_user [$time_local] $status ' '"$request" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; #访问日志 access_log logs/access.log main; sendfile on; tcp_nopush on; #根据实际情况调整，如果server很多，就调大一点 server_names_hash_bucket_size 128; # this seems to be required for some vhosts #这个例子是fastcgi的例子，如果用fastcgi就要仔细看 server { # php/fastcgi listen 80; #域名，可以有多个 server_name domain1.com www.domain1.com; #访问日志，和上面的级别不一样，应该是下级的覆盖上级的 access_log logs/domain1.access.log main; root html; location / { index index.html index.htm index.php; } #所有php后缀的，都通过fastcgi发送到1025端口上 #上面include的fastcgi.conf在此应该是有作用，如果你不include，那么就把fastcgi.conf的配置项放在这个下面。 location ~ /.php$ { fastcgi_pass 127.0.0.1:1025; } } #这个是反向代理的例子 server { # simple reverse-proxy listen 80; server_name domain2.com www.domain2.com; access_log logs/domain2.access.log main; #静态文件，nginx自己处理 location ~ ^/(images|javascript|js|css|flash|media|static)/ { root /var/www/virtual/big.server.com/htdocs; #过期30天，静态文件不怎么更新，过期可以设大一点，如果频繁更新，则可以设置得小一点。 expires 30d; } #把请求转发给后台web服务器，反向代理和fastcgi的区别是，反向代理后面是web服务器，fastcgi后台是fasstcgi监听进程，当然，协议也不一样。 location / { proxy_pass http://127.0.0.1:8080; } } #upstream的负载均衡，weight是权重，可以根据机器配置定义权重。据说nginx可以根据后台响应时间调整。后台需要多个web服务器。 upstream big_server_com { server 127.0.0.3:8000 weight=5; server 127.0.0.3:8001 weight=5; server 192.168.0.1:8000; server 192.168.0.1:8001; } server { listen 80; server_name big.server.com; access_log logs/big.server.access.log main; location / { proxy_pass http://big_server_com; } } } 上面说的include的几个文件，都没有必要改，用的时候include一下就可以。fastcgi.conf
