Memcached Distributed CacheWe use PHP to connect multiple memcached servers and do distributed caching, which is implemented as follows:$memcache New Memcache; $memcache->addserver (' 192.168.252.134 ', 11211); $memcache->addserver (' 192.168.252.134 ', 11212); $memcache->addserver (' 192.168.252.134 ', 11213); for ($i$i$i+ +) {$memcache->set ($i$i , 0, +);}This implementation is the most straightforward, simple, PHP application directly connected to the memcached server. But there is also a

Yesterday tried to build the NuGet image server with Nginx, the mirror server requires two functions: 1) reverse proxy; 2) content cache.Using Nginx as the reverse proxy, the configuration is very simple, just add a server setting with Proxy_pass in/etc/nginx/nginx.conf:server { listen ; Listen [::]:80; server_name the host name of the mirror server; Location/{ proxy_pass htt

The proxy HTTP server is single-threaded, and each request in the thread is processed sequentially, and other requests wait. When HTTP is used as a proxy server, it also copies every file it obtains into the local
