ngx_lua将lua嵌入到nginx，让nginx执行lua脚本，高并发，非阻塞的处理各种请求。
url请求nginx服务器，然后lua查询redis，返回json数据。
一.安装lua-nginx-module
参见《LNMLGC》架构
二.安装redis2-nginx-module模块
get https://github.com/openresty/echo-nginx-moduleget https://github.com/openresty/redis2-nginx-module
get https://github.com/agentzh/set-misc-nginx-module.git
#
./configure --prefix=/usr/local/nginx \
--with-debug \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-pcre=../pcre-8.21 \
--add-module=../ngx_devel_kit-0.2.19 \
--add-module=../lua-nginx-module-0.9.8 \
--add-module=../echo-nginx-module \
--add-module=../redis2-nginx-module \
--add-module=../set-misc-nginx-module
# make
# make install
三.安装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
四.安装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/
五.安装redis-lua
# git clone https:
//github.com/nrk/redis-lua.git
# cp redis-lua/src/redis.lua /usr/local/lua/lib/
六.配置
... http { ... upstream redis_pool { server localhost:6379; keepalive 1024 single; //定义连接池大小，当连接数达到此数后，后续的连接为短连接 } 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，放在nginx.conf同目录下
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 == 200 then reply = parser.parse_reply(res.body) value = json.encode(reply) ngx.say(value) a = json.decode(value) ngx.say(a[2]) end 七.测试
# 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"]
