其实在学校就已经用过nginx,那时候只是简单来做反向代理分流。昨天看了下nginx的配文件,感觉挺喜欢这种配置方法,也许这就是菜头所说的代码表现性(汗)
相比apache那种比较传统的配置方式,nginx的配置更像是一种微型的脚本语言,听说还有lua模块……
比如apache的vhost是这样的
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
而nginx是这样的
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
root /var/www/html;
index index.html index.htm;
# Make site accessible from http://localhost/
server_name localhost;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
#location /RequestDenied {
# proxy_pass http://127.0.0.1:8080;
#}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
#error_page 500 502 503 504 /50x.html;
#location = /50x.html {
# root /usr/share/nginx/html;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
# NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
# With php5-cgi alone:
#fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
显然,nginx的语法更接近语言而不是配置,这样的写法已经很像shell了。这样得到的直观感觉是nginx的配置更像是函数(其实就是模块)的调用。
在这要说明的一点是我很喜欢ubuntu那种把程序的配置文件拆开,用目录结构来管理的办法,这样比在centos上那种一大坨的配置文件好读多了。
# /etc/nginx/
# |-- nginx.conf
# |-- conf-enabled
# | `-- *
# `-- sites-enabled
# `-- *
