第一部分:全局块
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
这是nginx服务器并发处理服务的关键,worker_processes值越大,可以支持的并发处理量也越多,但是会受到硬件、软件等设备的制约。
第二部分:events块
events {
worker_connections 1024;
}
events块设计的指令主要影响nginx服务器与用户的网络连接,每个word_process可以同时支持的最大连接数等。
http块
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
}
代理、缓存、日志定义等绝大多数功能和第三方模块的配置都在这里。需要注意的是,http块也包括http全局块、server块。
server {
listen 80; #nginx目前监听的端口是80端口
server_name localhost;#主机名称:本地
#charset koi8-r;
#access_log logs/host.access.log main;
location / { #当路径中发现一个"/",就做一些请求跳转
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ { #正则表达式 当访问路径满足这个规则,就按如下配置操作
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
全局server块 | 最常见的配置是本虚拟机主机的监听配置和本虚拟机的名称或IP配置 |
---|---|
location块 | 一个server块可以配置多个location块 这块的主要功能是基于nginx服务器接收到的请求字符串(例如server_name/uri_string),对虚拟主机名称(也可以是IP别名)之外的字符串(例如前面的/uri_string)进行匹配,对特定的请求进行处理,地址定向、数据缓存和应答控制等功能,还有许多第三方模块的配置也在这里进行。 |
