nginx.conf核心配置文件内容如下:
#user nobody;
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
#默认使用epoll
use epoll;
#每个worker允许连接的客户端最大连接数
worker_connections 10240;
}
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;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
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$ {
# proxy_pass http://127.0.0.1;
#}

#
#location ~ /.ht {

#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#

}
1.设置worker进程的用户,指的linux的用户,会涉及到nginx操作目录或文件的一些权限,默认为nobody。
user root;
2.worker进程工作数设置,一般来说CPU有几个,就设置几个,或者设置N-1也行。
worker_processes 1;
3.nginx日志级别debug | info | notice | warn | error | crit | alert | emerg,错误级别从左到右越来越大。
4.设置nginx进程pid
pid logs/nginx.pid
5.设置工作模式
events {
# 默认使用epoll
use epoll;
# 每个worker允许连接的客户端最大连接数
worker_connections 10240;
}
6.http是指令块,针对http网络传输的一些指令配置
http {
}
7.include引入外部配置,提高可读性,避免单个配置文件过大。
include mime.types;
8.设定日志格式,main为定义的格式名称,比如access_log就可以直接使用这个变量了。
#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;
| 参数名 | 参数意义 |
|---|---|
| $remote_addr | 客户端ip |
| $remote_user | 远程客户端用户名,一般为:"-" |
| $time_local | 时间和时区 |
| $request | 请求的url以及method |
| $status | 响应状态码 |
| $body_bytes_send | 响应客户端内容字节数 |
| $http_referer | 记录用户从哪个链接跳转过来的 |
| $http_user_agent | 用户所使用的代理,一般来说都是浏览器。 |
| $http_x_forwarded_for | 通过代理服务器来记录客户端的ip |
9.sendfile使用使用高效文件传输,提升传输性能。启用后才能使用tcp_nopush,是指当数据表积累到一定大小之后才发送,节约资源损耗。
sendfile on; tcp_nopush on;
10.keepalive_timeout设置客户端与服务端请求的超时时间,保证客户端多次请求的时候不会重复建立新的连接,节约资源损耗。
#keepalive_timeout 0; keepalive_timeout 65;
11.gzip启用压缩,html/js/css压缩后传输会更快
#开启gzip压缩功能,目的:提高传输效率,节约带宽。 gzip on; #限制最小压缩,小于1字节文件不会被压缩 gzip_min_length 1; #定义压缩级别(压缩比,文件越大,压缩越多,但是cpu使用也越多) gzip_comp_level 3; #定义压缩文件类型 gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png application/json;
12.server可以在http指令块中设置多个虚拟主机
- listen 监听端口
- server_name localhost、ip、域名
- location 请求路由映射,匹配拦截
- root 请求位置
- index 首页位置
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
}
