nginx常用变量

一、安装命令：

--prefix=path：配置nginx安装部署的根目录，也就是工作目录。默认是：/usr/local/nginx/，便于一个系统可以配置多种nginx

--with-stream: 启用nginx的stream模块，让nginx直接启动tcp/udp协议

--with-threads：启动nginx线程池机制

--with-pcre=dir ,--with-openssl=dir：指定自己安装的pcre（正则表达式）源码和ssl（https源码）地址

--with-xxx_module:启用xxx功能模块

--without-xxx_module:关闭xxx功能模块

--add-module=path：增加某个模块，path指定源码目录

--add-dynamic-module=path:增加动态模块，path指定源码目录，编译后会生成*.so形式的动态库，nginx.conf需要引入这个动态模块：load_module path;path为动态模块路径

--with-dubge：启动dubug模式，输出dubug及其级别以上的信息，级别dubug最低

二、nginx.conf配置变量

#user nobody; //用户

worker_processes 1;//线程

#error_log logs/error.log;//错误日志存放地址

#error_log logs/error.log notice;//级别

#error_log logs/error.log info;

#pid logs/nginx.pid;//系统pid存放地址

events {

worker_connections 1024;//每个进程最大存放数量

}

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;//每个请求存放时间

#gzip on;//压缩命令开启/关闭

server {

listen 80;//监听端口

resolver：114.114.114.114//dns服务器解析地址

server_name localhost;//虚拟主机名称如：ip、域名

#charset koi8-r;//HTTP请求字节码格式

#access_log logs/host.access.log main;//http请求日志文件

location / {

root html;//根目录

index index.html index.htm;//默认文件地址

proxy_pass http://127.0.0.1;//代理服务器请求地址

}

#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;//代理服务器请求地址

#}

# 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 {

# root html;

# index index.html index.htm;

# }

#}

# HTTPS server

#server {

# listen 443 ssl;

# server_name localhost;

# ssl_certificate cert.pem;

# ssl_session_timeout 5m;

# ssl_ciphers HIGH:!aNULL:!MD5;

# ssl_prefer_server_ciphers on;

# location / {
