instead of redis2 openresty module I am using lua-redis module. Issue is every time when we hit same page request instead of serving response from cache it still serves from the source url.
Below is sample script from my config to create reverse proxy
`server {
listen 80 default_server;
listen [::]:80 default_server;
root /usr/local/openresty/nginx/html/default;
index index.html index.htm;
server_name _;
location / {
default_type application/json;
set $key $request_uri;
set_escape_uri $escaped_key $key;
srcache_fetch GET /redis-fetch $key;
srcache_store PUT /redis-store key=$escaped_key&exptime=3600;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://application-server:8200;
}
location = /redis-fetch {
internal ;
set_md5 $redis_key $args;
content_by_lua_block {
local redis = require "resty.redis"
local red = redis:new()
red:set_timeouts(1000, 1000, 1000)
local ok, err = red:connect("Redis Server", 16318)
if not ok then
ngx.say("failed to connect: ", err)
return
end
ok, err = red:get(ngx.var.redis_key)
if not ok then
ngx.say("failed to get key: ", err)
return
end
}
}
location = /redis-store {
internal;
set_unescape_uri $exptime $arg_exptime;
set_unescape_uri $key $arg_key;
set_md5 $key;
content_by_lua_block {
local redis = require "resty.redis"
local red = redis:new()
red:set_timeouts(1000, 1000, 1000)
local ok, err = red:connect("Redis Server", 16318)
if not ok then
ngx.say("failed to connect: ", err)
return
end
ok, err = red:set(ngx.var.key,ngx.var.echo_request_body)
if not ok then
ngx.say("failed to set key: ", err)
return
end
ok, err = red:expire(ngx.var.key,ngx.var.exptime)
}
Before explaining my issue, let me clear that I am very new to nginx/openresty work.
I am trying to see how I can use Redis to cache the most frequently requested pages and serve them from cache to improve the performance. I am following this example: https://github.com/openresty/srcache-nginx-module#caching-with-redis
instead of redis2 openresty module I am using lua-redis module. Issue is every time when we hit same page request instead of serving response from cache it still serves from the source url.
Below is sample script from my config to create reverse proxy
`server {
} location /example { default_type 'text/plain'; set $key "nginx-cache:$scheme $request_method $arg_key $host $request_uri $args"; return 200 $key; content_by_lua_block { ngx.say('Hello, Sammy!') } }
} ` Any help is appreciated.
