一、安装环境：
- CentOS x64 release 7.0(Final)
- Nginx-1.4.1 安装目录（/usr/local/nginx/conf）
- Redis 3.2.7 /home/appuser/nginx-lua-memcache/redis-3.2.7
二、安装步骤：
1、安装依赖
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers make pcre-devel yum -y install gd gd2 gd-devel gd2-devel lua lua-devel
2、安装Redis 3.2.7
wget http://download.redis.io/releases/redis-3.2.7.tar.gz
#tar -xzvf redis-2.6.14.tar.gz cd redis-2.6.14 make && make install
关于redis安装及使用详细教程，参见：http://www.cnblogs.com/codersay/p/4301677.html
redis添加白名单步骤
(1)#cd /home/appuser/nginx-lua-memcache/redis-3.2.7/src
(2) #./redis-cli
(3) #set ip 1(例如：set 192.168.1.2 1)
3、安装Nginx-1.4.1
./configure --prefix=/usr/local/nginx/ --with-http_gzip_static_module --add-module=/home/appuser/solftware/nginx-lua-memcache/ngx_devel_kit-0.2.18 --add-module=/home/appuser/solftware/nginx-lua-memcache/lua-nginx-module-0.8.5 --add-module=/home/appuser/solftware/nginx-lua-memcache/redis2-nginx-module-0.10
make
make install
4、下载nginx中lua使用redis需要的依赖包redis.lua到nginx安装目录
https://codeload.github.com/agentzh/lua-resty-redis/tar.gz/v0.15
5、将控制访问lua脚本access.lua放到nginx安装目录的conf目录下
6、在nginx.conf文件的http段引入redis.lua包，加入代码：
lua_package_path"/usr/local/nginx/redis.lua;;";
7、配置nginx
#user nobody;
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

worker_connections 2048;
}
http {
include mime.types;
default_type application/octet-stream;
lua_package_path "/usr/local/nginx/resty/redis.lua";

proxy_buffers 8 64k;
proxy_busy_buffers_size 128k;
proxy_temp_file_write_size 128k;

local redis = require "resty.redis"
local cache, err = redis.new()

}

}
注：(也可以将脚本引入nginx)access_by_lua_file/usr/local/nginx/conf/access.lua
注：redis默认不会将数据持久化，需要手动修改配置文件
8、现在可以启动redis和nginx进行测试了。
