Nginx完整配置说明

http://blog.csdn.net/marising/article/details/3979493

可以参考如下的完整例子

http://wiki.codemongers.com/NginxFullExample

[php] view plaincopy

#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

[c-sharp] view plaincopy

# fastcgi.conf

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

fastcgi_index index.php;

# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param REDIRECT_STATUS 200;

proxy.conf

[c-sharp] view plaincopy

# proxy.conf

proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

更多的，每个项的具体含义和配置选择，可以参考如下：

http://wiki.codemongers.com/NginxModules

可以依次从MainModule,Events Module,Http Core Module,Http UpStream Module的顺序看。

关于配置和模块的关系是，装了什么模块，就可以用到什么配置，因此配置是灵活多变的。
