bashcached

memcached server built on bash + socat

Feature

It is one file script (small, (($(< bashcached wc -l) < 100))!), and it requires only:

• bash
• socat

So, you can use it as soon as you download it.

It supports multiple connections and implements almost all memcached commands:

• set, add, replace, append and prepend
• get, delete and touch
• incr and decr
• gets and cas
• flush_all
• version and quit

And, it supports to serve over tcp and unix domain socket.

Install

You could install base64, bash and socat via brew if you use macOS:

$ brew install base64 bash socat

(In fact, bash is installed in the default on macOS, however it is too old to run bashcached.)

Or, you could install socat via apt if you use Ubuntu:

$ sudo apt install socat

then, download and chmod.

$ curl -LO https://git.io/bashcached
$ chmod +x bashcached

Or, you could use bpkg instaed of downloading script:

$ bpkg install MakeNowJust/bashcached -g
