Memcache is divided into server side and client side. The server is used to store the cache and the client is used to operate the cache.

Therefore, you can use Nginx to access Memcache directly and set cache key rules with Nginx built-in variables such as $uri and $args, so that when the cache hits, Nginx can skip the communication between fastcgi and PHP and get the data directly from memcache and return.

OpenResty is a high-performance Web platform based on Nginx and Lua, which integrates a large number of excellent Lua libraries, third-party modules and most dependencies. It is used to conveniently build dynamic Web applications, Web services and dynamic gateways that can handle ultra-high concurrency and high scalability.

1. Download the compressed package of openresty. Opwnresty contains its own nginx, so there is no need to install nginx.

[root@server2 ~] # tar zxf openresty-1.11.2.3.tar.gz

[root@server2 ~] # cd openresty-1.11.2.3

[root@server2 openresty-1.11.2.3] # yum install gcc-c++-y

[root@server2 openresty-1.11.2.3] # yum install pcre-devel-y

[root@server2 openresty-1.11.2.3] # yum install openssl-devel-y

[root@server2 openresty-1.11.2.3] #. / configure

[root@server2 openresty-1.11.2.3] # gmake

[root@server2 openresty-1.11.2.3] # gmake install

[root@server2 openresty-1.11.2.3] # cd / usr//local/openresty/nginx/conf/

two。 Change the configuration file

[root@server2 conf] # vim nginx.conf

# # #

18 http {

19 upstream memcache {# # nginx module, uosteam is mainly used to receive, process and forward data

20 server 127.0.0.1 11211; # # set the default port number

21}

52 location / memc {

53 internal; # # only accept internal access, not external http requests

54 memc_connect_timeout 100ms

55 memc_send_timeout 100ms

56 memc_read_timeout 100ms

57 set $memc_key $query_string; # # use $query_string built into Nginx as key

58 set $memc_exptime 300; # # cache expiration time

59 memc_pass memcache

60} # # key-value the requested URL and the valid results returned by the backend service into the memcache service

72 location ~\ .php$ {

73 set $key $uri$args

74 srcache_fetch GET / memc $key

# # registering an input interceptor to location, this configuration will be executed when location enters

75 srcache_store PUT / memc $key

# # registering an output interceptor to location, which will be executed when location execution is completed and output

76 root html

77 fastcgi_pass 172.0.0.60:9000

78 fastcgi_index index.php

79 include fastcgi.conf

80} # # configure caching for "~\ .php $", which means that all requests ending in ".php" will be cached

}

# # when the requested uri ends with ".php", first go to memcache to query whether there is data with $uri$args as key, and if so, return it directly; otherwise, execute the logic of location. If the returned http status code is 200, use $uri$args as key before output, and store the input result in memcache.

# # #

[root@server2 conf] # / usr/local/openresty/nginx/sbin/nginx-t

[root@server2 conf] # / usr/local/openresty/nginx/sbin/nginx-s reload

[root@server2 conf] # / etc/init.d/httpd start

# # Note: the port numbers of both http and nginx are 80, so you need to modify the port number of http.

[root@server2 html] # / etc/init.d/iptables stop

[root@server2 html] # yum install memcached-y

Test:

1. Open memcached and perform pressure test in the physical machine

[root@server2 conf] # / etc/init.d/memcached start

[root@foundation60 Desktop] # ab-c 10-n 50000 http://172.25.60.3/index.php

two。 Turn off memcached and perform stress test in the physical machine

[root@server2 conf] # / etc/init.d/memcached stop

[root@foundation60 Desktop] # ab-c 10-n 50000 http://172.25.60.3/index.php
