memcached

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;
: }
} 

指令

变量

• $memcached_key

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.

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.

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.

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.

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.

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.
