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

  2. server {
  3. : location / {
  4. : set  $memcached_key  $uri;
  5. : memcached_pass   name:11211;
  6. : default_type     text/html;
  7. : error_page       404 = /fallback;
  8. : }
  10. : location = /fallback {
  11. : proxy_pass       backend;
  12. : }
  13. }

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.
