redis 遠程登陸   bind 0.0.0.0  /etc/redis/redis.confi 修改這個配置文件就可遠程登陸上去  

啓動服務端 redis-server      1162 root     27372 S    redis-server 0.0.0.0:6379

啓動客戶端 redis-cli  

經常使用命令 : 

     1 顯示全部的鍵值   keys *

127.0.0.1:6379> keys *
 1) "term_app_info:1"
 2) "term_info:18"
 3) "term_info:23"
 4) "term_info:29"
 5) "term_info:11"

　  2  獲取值的信息

127.0.0.1:6379> HGETall term_info:36
 1) "timestamp"
 2) "1533185362"
 3) "mac"

　　

　　3 準備用lua 鏈接redis 數據庫

          而後從找到了開源的redis lua   https://github.com/openresty/lua-resty-redis

　　  https://github.com/gitforks/redis-lua

          而後又來個了nigx配置

　　   D:\GIT\Q3_mysql\zk_openwrt\wac\nginx.conf  

　　  

　　　　location /demo {
　　　　　　default_type text/html;
　　　　　　content_by_lua '
　　　　　　ngx.say("<p>hello, nginx</p>")';　　
　　　　}

           經過web能夠訪問  　　  http://192.168.1.1:8080/demo  

          頁面看到    hello, nginx       (ngx.say 說在頁面上的  )

          文件路徑很重要          /etc/nginx/nginx.conf   

         新加一個server的配置

　　

    server {
        listen       8822;
        server_name  localhost;
        root /tmp/portal_cache/;

        location /test {

http://192.168.1.1:8822/test 經過訪問觸發就能夠修改數據庫, 測試有效

 /usr/local/openresty/nginx/nginx.conf    

在個人虛擬機裏面執行的: openresty -c ~/work/conf/nginx.conf

這個是他的中文網站 : http://openresty.org/cn/components.html   

www.xiaohuamao.top:8022 體驗了下openresty    

git hub 地址 https://github.com/openresty/openresty  能夠學習下

這裏還有個開源項目 https://gitee.com/alexa/VeryNginx

 

Redis transactions  事務 因此 Redis 的內部能夠保持簡單且快速

client:select(15) -- for testing purposes 選擇15號數據庫, 默認在0號數據庫, 你在15號數據庫找0號數據庫的東西怎麼找獲得呢? 

從redis 裏面讀取數據而後寫入mysql 裏面永久存儲

從redis 裏面讀取數據而後顯示到頁面上  速度快的很嘛  

DBSIZE 能夠看到有多少條數據 keys * 可能卡

-- 演示將多條記錄數據組合成一條sql插入語句(for mysql)
