Nginx+lua+redis High Concurrent Application construction

Ngx_lua Lua into Nginx, let Nginx run Lua script. High concurrency, non-clogging process for various requests.

The URL requires Nginxserver, and LUA queries Redis to return the JSON data.

I. Installation Lua-nginx-module

See the architecture of LNMLGC

Two. Installing the Redis2-nginx-module module

Get Https://github.com/openresty/echo-nginx-module
Get Https://github.com/openresty/redis2-nginx-module
Get Https://github.com/agentzh/set-misc-nginx-module.git

# make
# make install

Three. Install Lua-redis-parser
# git clone https:
//github.com/agentzh/lua-redis-parser.git
# Export Lua_ include_dir=/usr/local/include/luajit-2.0
# make CC=GCC
# make install CC=GCC

four. Installing the JSON
# wget http:
//files.luaforge.net/releases/json/json/0.9.50/json4lua-0.9.50.zip
# Unzip Json4lua-0.9.50.zip
# cp json4lua-0.9.50/json/json.lua/usr/local/lua/lib/

Five. Install Redis-lua
# git clone https:
//github.com/nrk/redis-lua.git
# CP redis-lua/src/redis.lua/usr/ local/lua/lib/

six. Configure

..... http {    ...    Upstream Redis_pool {        server localhost:6379;        KeepAlive;        Defines the connection pool size when the number of connections reaches this number. Maybe the connection is short connection    }    server {        ...        location/get_redis{            #internal;            Set_unescape_uri $key $arg _key;            Redis2_query Hgetall $key;            Redis2_pass redis_pool;        }        Location/json {            content_by_lua_file Conf/test.lua;}}    }

# VI Test.lua, placed under the Nginx.conf folder

Local JSON = require ("JSON") local parser = require ("Redis.parser") Local res = Ngx.location.capture ("/get_redis", {  args = {key = Ngx.var.arg_key}}) If Res.status = = then  reply = parser.parse_reply (res.body)  value = Json.enco De (Reply)  Ngx.say (value)  a = Json.decode (value)  Ngx.say (a[2]) end

Seven. Test
# REDIS-CLI
127.0.0.1:6379> hmset Ttlsa www www.ttlsa.com mail mail.ttlsa.com
Ok
127.0.0.1:6379> Hgetall Ttlsa
1) "www"
2) "Www.ttlsa.com"
3) "Mail"
4) "Mail.ttlsa.com"

# Curl Http://localhost/json?

Key=ttlsa

["www", "www.ttlsa.com", "Mail", "mail.ttlsa.com"]
