#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|java script|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

# 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 REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; 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

# 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; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffers 32 4k;

mine.types

# mime.types types { text/html html htm shtml; text/css css; text/xml xml rss; image/gif gif; image/jpeg jpeg jpg; application/x-java script js; text/plain txt; text/x-component htc; text/mathml mml; image/png png; image/x-icon ico; image/x-jng jng; image/vnd.wap.wbmp wbmp; application/java-archive jar war ear; application/mac-binhex40 hqx; application/pdf pdf; application/x-cocoa cco; application/x-java-archive-diff jardiff; application/x-java-jnlp-file jnlp; application/x-makeself run; application/x-perl pl pm; application/x-pilot prc pdb; application/x-rar-compressed rar; application/x-redhat-package-manager rpm; application/x-sea sea; application/x-shockwave-flash swf; application/x-stuffit sit; application/x-tcl tcl tk; application/x-x509-ca-cert der pem crt; application/x-xpinstall xpi; application/zip zip; application/octet-stream deb; application/octet-stream bin exe dll; application/octet-stream dmg; application/octet-stream eot; application/octet-stream iso img; application/octet-stream msi msp msm; audio/mpeg mp3; audio/x-realaudio ra; video/mpeg mpeg mpg; video/quicktime mov; video/x-flv flv; video/x-msvideo avi; video/x-ms-wmv wmv; video/x-ms-asf asx asf; video/x-mng mng; }
