nginx 读 章亦春 的博客 的笔记

打开目录浏览功能
http://wenku.baidu.com/view/1acdff2b453610661ed9f4f0.html###
打开nginx.conf文件，在location server 或 http段中加入
autoindex on;
就可以访问目录结构了

读nginx笔记http://blog.sina.com.cn/s/blog_6d579ff40100wi7p.html
环境fedora17

yum install zlib
yum install pcre-devel

解压nginx和echo-nginx-module
下载地址
https://github.com/agentzh/echo-nginx-module/tags
[code="java"]# ./configure --prefix=/usr/local/nginx/ --add-module=/root/nginx_test/module/agentzh-echo-nginx-module-9259898
[/code]

nginx.conf

最上面
user  root;
否则403
.....server的上面添加
    geo $dollar {
        default "$";
    }

    server {
..........
     添加
        location /test {
                echo "This is a dollar sign: $dollar";
        }

./nginx
curl http://localhost/test
输出
This is a dollar sign: $
★★★★★★★★★★★★★★★★★★

location /test1 {
            set $first "hello ";
            echo "${first}world";
        }

curl localhost/test1
hello world
★★★★★★★★★★★★★
内部跳转
[color=red] echo_exec [/color]

location /foo {
            set $a hello;
            echo_exec /bar;
        }

        location /bar {
            echo "a = [$a]";
        }

结果
[code="java"]
# curl localhost/foo
a = [hello]
#
[/code]
[color=red]类似内联，可通过这种方式传递变量[/color]
★★★★★★★★★★★★★★★
另一种写法[color=red] rewrite [/color]

  location /foo {
            set $a hello;
            rewrite ^ /bar;
        }

        location /bar {
            echo "a = [$a]";
        }

rewrite 还能进行301和302的外部跳转

★★★★★★★★★★★★★★

location /test {
       echo "uri = $uri";
       echo "request_uri = $request_uri";
}

[color=red]注意这俩是只读 的[/color]
结果
[code="java"]# curl 'http://localhost/test?a=b'
uri = /test
request_uri = /test?a=b
# [/code]

★★★★★★
$arg_XXX 变量群。

 location /test {
        echo "name: $arg_name";
        echo "class: $arg_class";
    }

结果

$ curl 'http://localhost:8080/test'
    name: 
    class: 

    $ curl 'http://localhost:8080/test?name=Tom&class=3'
    name: Tom
    class: 3

转义可以用

 location /test {
        set_unescape_uri $name $arg_name;
        set_unescape_uri $class $arg_class;

        echo "name: $name";
        echo "class: $class";
    }

★★★★★★★★★★★
以下为Nginx 变量漫谈（三）

 
server {
        listen 8080;

        location /test {
            set $args "foo=1&bar=2";
            proxy_pass http://127.0.0.1:8081/args;
        }
    }

    server {
        listen 8081;

        location /args {
            echo "args: $args";
        }
    }

输出

 $ curl 'http://localhost:8080/test?blah=7'
    args: foo=1&bar=2

综上

整个nginx.conf为

[code="java"]# cat nginx.conf

user root;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;
