第一步：進入opresty目錄

[root@node03 openresty]# cd /export/servers/openresty/[root@node03 openresty]# lltotal 356drwxr-xr-x 2 root root  4096 Jul 26 11:33 bindrwxrwxr-x 44 1000 1000  4096 Jul 26 11:31 builddrwxrwxr-x 43 1000 1000  4096 Nov 13 2017 bundle-rwxrwxr-x 1 1000 1000 45908 Nov 13 2017 configure-rw-rw-r-- 1 1000 1000 22924 Nov 13 2017 COPYRIGHTdrwxr-xr-x 6 root root  4096 Jul 26 11:33 luajitdrwxr-xr-x 6 root root  4096 Aug 1 08:14 lualib-rw-r--r-- 1 root root  5413 Jul 26 11:32 Makefiledrwxr-xr-x 11 root root  4096 Jul 26 11:35 nginxdrwxrwxr-x 2 1000 1000  4096 Nov 13 2017 patchesdrwxr-xr-x 44 root root  4096 Jul 26 11:33 pod-rw-rw-r-- 1 1000 1000  3689 Nov 13 2017 README.markdown-rw-rw-r-- 1 1000 1000  8690 Nov 13 2017 README-win32.txt-rw-r--r-- 1 root root 218352 Jul 26 11:33 resty.indexdrwxr-xr-x 5 root root  4096 Jul 26 11:33 sitedrwxr-xr-x 2 root root  4096 Aug 1 10:54 testluadrwxrwxr-x 2 1000 1000  4096 Nov 13 2017 util[root@node03 openresty]# 

說明：接下來我們關注兩個目錄 lualib 和 nginx

​ 1.lualib: 是存放opresty所需要的集成軟件包的

​ 2.nginx： 是nginx服務目錄

接下來，我們進入lualib目錄一看究竟：

[root@node03 openresty]# cd lualib/[root@node03 lualib]# lltotal 116-rwxr-xr-x 1 root root 101809 Jul 26 11:33 cjson.sodrwxr-xr-x 3 root root  4096 Jul 26 11:33 ngxdrwxr-xr-x 2 root root  4096 Jul 26 11:33 rdsdrwxr-xr-x 2 root root  4096 Jul 26 11:33 redisdrwxr-xr-x 9 root root  4096 Aug 1 10:34 resty

這里我們看到了redis和ngx集成軟件包，說明我們可以之間使用nginx和redis而無需導入任何依賴包?。。。?/p>

下面看看resty里面有些說明呢？？？？
