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

  1. server {
  2. : location / {
  3. : set $memcached_key $uri;
  4. : memcached_pass name:11211;
  5. : default_type text/html;
  6. : error_page 404 = /fallback;
  7. : }
  8. : location = /fallback {
  9. : proxy_pass backend;
  10. : }
  11. }

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.
