ngx_luaredisphp比较,Nginx嵌入Lua语言实现redis的高性能http接口

redis没有直接提供一个http的接口&＃xff0c;要是用php&＃xff0c;python&＃xff0c;当然也是可以实现的。

性能的比较的话&＃xff0c;lua的能力要比php强的不少。。。

网上有很多的性能的比较&＃xff0c;我也做过几次的压力测试&＃xff0c;lua的性能确实很强。。。。

安装nginx&＃xff0c;以及lua环境git clone https://github.com/simpl/ngx_devel_kit.git

git clone https://github.com/chaoslawful/lua-nginx-module.git

git clone https://github.com/agentzh/redis2-nginx-module.git

git clone https://github.com/agentzh/set-misc-nginx-module.git

git clone https://github.com/agentzh/echo-nginx-module.git

yum -y install pcre pcre-dev*

wget http://nginx.org/download/nginx-1.3.14.tar.gz

tar zxvf nginx-1.3.14.tar.gz

cd nginx-1.3.14

./configure --prefix&＃61;/usr/local/nginx --add-module&＃61;../ngx_devel_kit/ --add-module&＃61;../lua-nginx-module --add-module&＃61;../redis2-nginx-module --add-module&＃61;../set-misc-nginx-module --add-module&＃61;../echo-nginx-module

make && make install

注&＃xff1a;在 server 段里&＃xff0c;加入代码&＃xff0c;如果不加此代码或者设置为 on 时&＃xff0c;则需要重启 Nginx。

lua_code_cache off;

Nginx.conf

server{

listen 80;

server_name test.lua.com;

#http://test.lua.com/lua

location /hello {

default_type "text/plain";

content_by_lua &＃39;ngx.say("Nginx Lua Hello!")&＃39;;

}

#GET http://test.lua.com/get?key&＃61;key

location /get {

set_unescape_uri $key $arg_key;

redis2_query get $key;

redis2_pass 127.0.0.1:6379; #配置redis访问

}

#SET http://test.lua.com/set?key&＃61;key&val&＃61;value

location /set {

set_unescape_uri $key $arg_key;

set_unescape_uri $val $arg_val;

redis2_query set $key $val;

redis2_pass 127.0.0.1:6379;

}

}

重启Nginx

/etc/init.d/nginx restart

也可以直接用lua调用redis的接口

local ckid &＃61; redis.pcall(&＃39;get&＃39;,KEYS[1])

local meta

if ckid ~&＃61; nil then

meta &＃61; redis.call(&＃39;hgetall&＃39;, ckid)

else

meta &＃61; &＃39;none&＃39;

ckid &＃61; &＃39;none&＃39;

end

return {ckid, meta}

分享一个完成的实例&＃xff1a;location /foo {

set $value &＃39;first&＃39;;

redis2_query set one $value;

redis2_pass 127.0.0.1:6379;

}

# GET /get?key&＃61;some_key

location /get {

set_unescape_uri $key $arg_key; # this requires ngx_set_misc

redis2_query get $key;

redis2_pass foo.com:6379;

}

# GET /set?key&＃61;one&val&＃61;first%20value

location /set {

set_unescape_uri $key $arg_key; # this requires ngx_set_misc

set_unescape_uri $val $arg_val; # this requires ngx_set_misc

redis2_query set $key $val;

redis2_pass foo.com:6379;

}

# multiple pipelined queries

location /foo {

set $value &＃39;first&＃39;;

redis2_query set one $value;

redis2_query get one;

redis2_query set one two;

redis2_query get one;

redis2_pass 127.0.0.1:6379;

}

location /bar {

# $ is not special here...

redis2_literal_raw_query &＃39;*1\r\n$4\r\nping\r\n&＃39;;

redis2_pass 127.0.0.1:6379;

}

location /bar {

# variables can be used below and $ is special

redis2_raw_query &＃39;get one\r\n&＃39;;

redis2_pass 127.0.0.1:6379;

}

# GET /baz?get%20foo%0d%0a

location /baz {

set_unescape_uri $query $query_string; # this requires the ngx_set_misc module

redis2_raw_query $query;

redis2_pass 127.0.0.1:6379;

}

location /init {

redis2_query del key1;

redis2_query lpush key1 C;

redis2_query lpush key1 B;

redis2_query lpush key1 A;

redis2_pass 127.0.0.1:6379;

}

location /get {

redis2_query lrange key1 0 -1;

redis2_pass 127.0.0.1:6379;
