If you're using the ngx_openresty bundle (http://openresty.org ), then
you don't need to do anything because it includes and enables
lua-resty-redis by default. And you can just use it in your Lua code,
as in

local redis = require "resty.redis"
...

If you're using your own nginx + ngx_lua build, then just configure
the lua_package_path directive to add the path of your lua-resty-redis
install visible to ngx_lua's LUA_PATH search path, as in

# nginx.conf
http {
    lua_package_path "/path/to/lua-resty-redis/lib/?.lua;;";
    ...
}

For reference, the error is as follows:

This file is necessary to install lua-resty-redis into a custom nginx compilation. Is it available somewhere, or is this meant to be part of another module somehow?

lua-resty-redis is not an Nginx C module. It is a pure Lua library
that can be directly required from within your Lua code running via
the ngx_lua module.

[josegonzalez]

After I include the lua_package in it's path, I can use it as in your openresty example?

Something like:

    http {
        lua_package_path "/path/to/lua-resty-redis/lib/?.lua;;";
        local redis = require "resty.redis"
        ...
    }

Your nginx.conf syntax is not exactly right.

Look at the code sample in lua-resty-redis's README file:

https://github.com/agentzh/lua-resty-redis#synopsis

So something like:

server {
    lua_package_path "/path/to/lua-resty-redis/lib/?.lua;;";

    location /test {
        content_by_lua '
            local redis = require "resty.redis"
            ...
        '
    }
}

?

Try it and see what it says :) When in doubt, just try out the
openresty bundle instead to save your time.

Heh, will do. I mostly need a custom package - without some openresty stuff, and with other things - so just trying openresty won't solve all my problems.

Thanks for the advice, I'll let you know how it went and open a PR for this soon!

I don't get it here. The openresty package is fully customizable. You
can disable things and add things, just with the standard nginx
distribution.

You can find all the options available with its ./configure script by
passing the --help option.

Hey @agentzh : I am using openresty to configure nginx to communicate to redis sentinels. But I am unable to connect to them as it says "no field package ['resty.redis.connector']" . Can you suggest a solution for connecting nginx with redis sentinels ?

[agentzh]

@Mahanteshambi Please do not hijack unrelated issues like this. It's annoying. Your questions should post to the openresty-en mailing list instead. See http://openresty.org/en/community.html
