Centos7环境下搭建Nginx+Lua+Redis进行数据存取

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

 

1.安装依赖环境

yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

2.安装LuaJIT

cd /usr/local/

mkdir LuaJIT

cd /usr/local/LuaJIT
wget http:
//luajit.org/download/LuaJIT-2.0.2.tar.gz
tar –xvf LuaJIT
-2.0.2.tar.gz cd LuaJIT-2.0.2 make install

3.安装nginx

cd /usr/local/

mkdir nginx 

下载ngx_devel_kit

wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz

下载lua-nginx-module

wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz

下载nginx

wget http://nginx.org/download/nginx-1.12.1.tar.gz 

解压文件

tar -xvf ngx_devel_kit-0.3.0 .tar.gz

tar -xvf lua-nginx-module-0.10.9rc7.tar.gz

tar -xvf nginx-1.12.1.tar.gz

编译nginx

cd nginx-1.12.1

./configure --prefix=/usr/local/nginx --add-module=../ngx_devel_kit-0.3.0 --add-module=../lua-nginx-module-0.10.9rc7

安装

make

make install

或者合并两个命令(4表示并行运行任务的数量)

make -j 4 && make install 

启动nginx

cd /usr/local/nginx/sbin

./nginx

测试是否启动成功:

访问  http:127.0.0.1:80

显示welcome to n ginx!表示启动成功

 

 

 

关闭nginx

./nginx –s stop

 

4.安装redis

cd /usr/local

mkdir redis 

下载

wget http://download.redis.io/releases/ redis-2.8.17.tar.gz

解压

tar -xvf redis-2.8.17.tar.gz

进入解压后的文件夹

cd redis-2.8.17

安装

make

启动redis(&表示后台运行)

cd src

./redis-server & 

启动成功后按ctrl+c退出启动界面

测试

./redis-cli

set foo liq  ---OK

get foo ---liq

关闭redis

SHUTDOWN

 

 

5.配置redis主从

 

5.1主reids 配置文件

 复制一份redis的配置文件:

cd /usr/local/redis/redis-2.8.17

mkdir –p 6379/data 6380/data

cp redis.conf  /usr/local/redis/redis-2.8.17/6379/data/redis-6379.conf

编辑文件

cd /usr/local/redis/ redis-2.8.17/6379/data/

vim redis-6379.conf
cd /usr/local/redis/ redis-2.8.17/6379/data/

vim redis-6379.conf

5.1.1

  daemonize no

  修改为:

  daemonize yes  (后台程序方式运行)

5.1.2

  pidfile /var/run/redis_6379.pid

  修改为:

  pidfile /usr/local/redis/redis-2.8.17/6379/redis_6379.pid

5.1.3

  //设置请求密码

  requirepass system

5.1.4

  //设置数据文件路径

  dir /usr/local/redis/redis-2.8.17/6379/data

 

 

5.2从reids 配置文件

 

cp /usr/local/redis/redis-2.8.17/6379/data/redis-6379.conf /usr/local/redis/redis-2.8.17/6380/data/redis-6380.conf

5.2.1

       port 改为6380

5.2.2

       pidfile 改为/usr/local/redis/redis-2.8.17/6380/redis_6380.pid

5.2.2

  删除 requirepass system

5.2.3

  //设置数据文件路径

  dir /usr/local/redis/redis-2.8.17/6380/data

5.2.4

  添加从属关系

  slaveof 127.0.0.1 6379

5.2.5

  添加主redis访问密码

       masterauth system

 

 

5.3启动redis

 

/usr/local/redis/redis-2.8.17/src/redis-server /usr/local/redis/redis-2.8.17/6379/redis-6379.conf
/usr/local/redis/redis-2.8.17/src/redis-server /usr/local/redis/redis-2.8.17/6380/redis-6380.conf

 

5.4测试主从

在主redis中存数据

cd /usr/local/redis/redis-2.8.17/src

./redis-cli -h 127.0.0.1 -p 6379 auth system

set foo test

ctrl+c退出

在从redis中取数据

./redis-cli -h 127.0.0.1 -p 6380

get foo

 

 

6.安装lua-resty-redis

 

https://github.com/openresty/lua-resty-redis.git下载lua-resty-redis-master后解压

将lib包安装到lua库

cd lua-resty-redis-master

make && make install

安装完成之后在/usr/local/lib/lua/resty里面会有redis.lua

 

7.修改nginx配置文件

cd /usr/local/nginx/conf

vim nginx.conf

7.1

http内添加 lua_package_path "/usr/local/lib/lua/?.lua;;";

7.2

server  listen改为 9080;

7.3

server 内添加

location /lua/set {

             default_type 'text/plain';

           content_by_lua_file conf/lua/setKeyValue.lua;

    }

    location /lua/get {

             default_type 'text/plain';

           content_by_lua_file conf/lua/getKey.lua;

    }

 

完整配置文件nginx.cnof:

 

worker_processes  1;

events {

    worker_connections  1024;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    lua_package_path "/usr/local/lib/lua/?.lua;;";

    sendfile        on;

    keepalive_timeout  65;

    server {

        listen       9080;

        server_name  localhost;

        location / {

            root   html;

            index  index.html index.htm;

        }

        location /lua/set {

             default_type 'text/plain';

           content_by_lua_file conf/lua/setKeyValue.lua;

        }

        location /lua/get {

             default_type 'text/plain';

           content_by_lua_file conf/lua/getKey.lua;

        }

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

            root   html;

        }
    }
}

 

8.编写content_by_lua_file对应的lua脚本

  8.1

#对应nginx中的配置:  content_by_lua_file conf/lua/setKeyValue.lua;

cd /usr/local/nginx/conf

mkdir lua

cd lua

vim setKeyValue.lua

setKeyValue.lua
代码:
--receive request params

local request_method = ngx.var.request_method

local args = nil

local key = nil

local value = nil

--获取参数的值

if "GET" == request_method then

    args = ngx.req.get_uri_args()

elseif "POST" == request_method then

    ngx.req.read_body()

    args = ngx.req.get_post_args()

end

key = args["key"]

value = args["value"]

 

--connect redis

local redis = require "resty.redis"

 

local cache = redis.new() 

 

local ok, err = cache.connect(cache, '127.0.0.1', '6379') 

 

cache:set_timeout(60000) 

 

if not ok then 

        ngx.say("failed to connect:", err) 

        return 

end 

 

-- 请注意这里 auth 的调用过程

-- check password

local count

count, err = cache:get_reused_times()

if 0 == count then

    ok, err = cache:auth("system")

if not ok then

       ngx.say("failed to auth: ", err)

       return

end

elseif err then

    ngx.say("failed to get reused times: ", err)

return

end

 

local res, err = cache:set(key, value) 

if not res then 

        ngx.say("failed to set "..key..": ", err) 

        return 

end 

 

if res == ngx.null then 

        ngx.say(key.." not found.") 

        return 

end 

 

ngx.say("set redis value >>> "..key..": ", res) 

 

 

local ok, err = cache:close() 

 

if not ok then 

        ngx.say("failed to close:", err) 

        return 

end 

 

8.2

#对应nginx中的配置: content_by_lua_file conf/lua/getKey.lua;

vim getKey.lua

getKey.lua代码:

 

--receive request params

local request_method = ngx.var.request_method

local args = nil

local key = nil

local value = nil

--获取参数的值

if "GET" == request_method then

    args = ngx.req.get_uri_args()

elseif "POST" == request_method then

    ngx.req.read_body()

    args = ngx.req.get_post_args()

end

key = args["key"]

value = args["value"]

 

--connect redis

local redis = require "resty.redis"

 

local cache = redis.new() 

 

local ok, err = cache.connect(cache, '127.0.0.1', '6380') 

 

cache:set_timeout(60000) 

 

if not ok then 

        ngx.say("failed to connect:", err) 

        return 

end 

 

local res, err = cache:get(key) 

if not res then 

        ngx.say("failed to get "..key..": ", err) 

        return 

end 

 

if res == ngx.null then 

        ngx.say(key.." not found.") 

        return 

end 

ngx.say("get from redis >>> "..key..": ", res) 

local ok, err = cache:close() 

 

if not ok then 

        ngx.say("failed to close:", err) 

        return 

end  

 

9.开启端口映射(如果不是安装在虚拟机上的不需要此步骤)

9.1开启虚拟机端口映射:

 

9.2开放9080端口的防火墙(--permanent永久生效,没有此参数重启后失效):

firewall-cmd --zone=public --add-port=9080/tcp  --permanent

 

10.重新启动nginx

cd /usr/local/nginx/sbin

./nginx 

11.查看效果

 

 

存值 -- 访问网址并传参: 

http://localhost:9080/lua/set?key=foo&value=test1

 

 

取值 -- 访问网址并传参:

http://localhost:9080/lua/get?key=foo
