To serve a Redis key with Nginx, you can use a Lua script along with the Nginx Lua module. Here is a basic example of how you can achieve this:
- Install the Nginx Lua module by following the instructions on the module's GitHub page: https://github.com/openresty/lua-nginx-module
- Create a Lua script that will connect to Redis and fetch the key value:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
local resty_redis = require "resty.redis"
local redis = resty_redis:new()
redis:set_timeout(1000) -- 1 second timeout
local ok, err = redis:connect("127.0.0.1", 6379)
if not ok then
ngx.log(ngx.ERR, "failed to connect to Redis: ", err)
return ngx.exit(500)
end
local res, err = redis:get("your_redis_key")
if not res then
ngx.log(ngx.ERR, "failed to get Redis key: ", err)
return ngx.exit(500)
end
redis:set_keepalive(10000, 100) -- keep connection alive for 10 seconds
ngx.say(res)
|
- Configure Nginx to use the Lua script with a location block like this:
1 2 3 4 |
location /redis {
default_type 'text/plain';
content_by_lua_file /path/to/your/lua/script.lua;
}
|
- Restart Nginx for the changes to take effect.
Now, when you access the URL /redis on your Nginx server, the Lua script will connect to Redis, fetch the value of the specified key, and return it to the client.
