本文介绍如何用Nginx+Lua+Redis来构建高并发Web应用,Curl请求Nginx,Nginx通过Lua查询Redis,返回json数据。
1、安装lua-redis-parser
#git clone https://github.com/agentzh/lua-redis-parser.git #export LUA_INCLUDE_DIR=/usr/include/lua5.1 #make CC=gcc #make install CC=gcc
2、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/share/lua/5.1/
3、安装redis-lua
#git clone https://github.com/nrk/redis-lua.git #cp redis-lua/src/redis.lua /usr/share/lua/5.1/
#vi /etc/nginx/nginx.conf http { include mime.types; default_type application/octet-stream; access_log logs/access.log; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 60; types_hash_max_size 2048; server_tokens off; lua_code_cache on; upstream redis_pool { server 192.168.1.105:6379; 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 { listen 80; server_name 192.168.1.104; 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_redis.lua; } } }
三、测试
1、编写脚本
编写上面配置中的test_redis.lua脚本
#vi test_redis.lua 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
2、构造数据
#redis-cli -h 192.168.1.105 -p 6379 redis 192.168.1.105:6379>HMSET testnlr www www.scutephp.com mail mail.scutephp.com
3、开始测试
#curl 'http://192.168.1.104/json?key=testnlr' ["www", "www.scutephp.com", "mail", "mail. scutephp.com"]
