ngx_http_memcached_module

你可以利用本模块来进行简单的缓存以提高系统效率。本模块计划在未来进行扩展。

__配置示例__

server {
: location / {
: set  $memcached_key  $uri;
: memcached_pass   name:11211;
: default_type     text/html;
: error_page       404 = /fallback;
: }

: location = /fallback {
: proxy_pass       backend;
: }
}

变量

• $memcached_key

Template:Anchor

memcached_pass

语法： memcached_pass [ name:port ]

默认值： none

作用域： http, server, location

The backend should set the data in memcached. The memcached key is "/uri?args".

Since 0.5.9 the memcached key is now in $memcached_key.

Template:Anchor

memcached_connect_timeout

语法： memcached_connect_timeout [ time ]

默认值： 60000

作用域： http, server, location

The timeout for connecting to memcached, in milliseconds.

Template:Anchor

memcached_read_timeout

语法： memcached_read_timeout [ time ]

默认值： 60000

作用域： http, server, location

The timeout for reading from memcached, in milliseconds.

Template:Anchor

memcached_send_timeout

语法： memcached_send_timeout [ time ]

默认值： 60000

作用域： http, server, location

The timeout for sending to memcached, in milliseconds.

Template:Anchor

memcached_buffer_size

语法： memcached_buffer_size [ size ]

默认值： see getpagesize(2)

作用域： http, server, location

The recv/send buffer size, in bytes.

Template:Anchor

memcached_next_upstream

语法： memcached_next_upstream [ error | timeout | invalid_response | not_found | off ]

默认值： error timeout

作用域： http, server, location

Which failure conditions should cause the request to be forwarded to another upstream server? Applies only when the value in memcached_pass is an upstream with two or more servers.
