第一步：进入opresty目录
[root@node03 openresty]# cd /export/servers/openresty/ [root@node03 openresty]# ll total 356 drwxr-xr-x 2 root root 4096 Jul 26 11:33 bin drwxrwxr-x 44 1000 1000 4096 Jul 26 11:31 build drwxrwxr-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 COPYRIGHT drwxr-xr-x 6 root root 4096 Jul 26 11:33 luajit drwxr-xr-x 6 root root 4096 Aug 1 08:14 lualib -rw-r--r-- 1 root root 5413 Jul 26 11:32 Makefile drwxr-xr-x 11 root root 4096 Jul 26 11:35 nginx drwxrwxr-x 2 1000 1000 4096 Nov 13 2017 patches drwxr-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.index drwxr-xr-x 5 root root 4096 Jul 26 11:33 site drwxr-xr-x 2 root root 4096 Aug 1 10:54 testlua drwxrwxr-x 2 1000 1000 4096 Nov 13 2017 util [root@node03 openresty]#
说明：接下来我们关注两个目录 lualib 和 nginx
1.lualib: 是存放opresty所需要的集成软件包的
2.nginx： 是nginx服务目录
接下来，我们进入lualib目录一看究竟：
[root@node03 openresty]# cd lualib/ [root@node03 lualib]# ll total 116 -rwxr-xr-x 1 root root 101809 Jul 26 11:33 cjson.so drwxr-xr-x 3 root root 4096 Jul 26 11:33 ngx drwxr-xr-x 2 root root 4096 Jul 26 11:33 rds drwxr-xr-x 2 root root 4096 Jul 26 11:33 redis drwxr-xr-x 9 root root 4096 Aug 1 10:34 resty
这里我们看到了redis和ngx集成软件包，说明我们可以之间使用nginx和redis而无需导入任何依赖包！！！！
下面看看resty里面有些说明呢？？？？
[root@node03 lualib]# cd resty/ [root@node03 resty]# ll total 152 -rw-r--r-- 1 root root 6409 Jul 26 11:33 aes.lua drwxr-xr-x 2 root root 4096 Jul 26 11:33 core -rw-r--r-- 1 root root 596 Jul 26 11:33 core.lua drwxr-xr-x 2 root root 4096 Jul 26 11:33 dns drwxr-xr-x 2 root root 4096 Aug 1 10:42 kafka #这是我们自己导入的 drwxr-xr-x 2 root root 4096 Jul 26 11:33 limit -rw-r--r-- 1 root root 4616 Jul 26 11:33 lock.lua drwxr-xr-x 2 root root 4096 Jul 26 11:33 lrucache -rw-r--r-- 1 root root 4620 Jul 26 11:33 lrucache.lua -rw-r--r-- 1 root root 1211 Jul 26 11:33 md5.lua -rw-r--r-- 1 root root 14544 Jul 26 11:33 memcached.lua -rw-r--r-- 1 root root 21577 Jul 26 11:33 mysql.lua -rw-r--r-- 1 root root 616 Jul 26 11:33 random.lua -rw-r--r-- 1 root root 9227 Jul 26 11:33 redis.lua -rw-r--r-- 1 root root 1192 Jul 26 11:33 sha1.lua -rw-r--r-- 1 root root 1045 Jul 26 11:33 sha224.lua -rw-r--r-- 1 root root 1221 Jul 26 11:33 sha256.lua -rw-r--r-- 1 root root 1045 Jul 26 11:33 sha384.lua -rw-r--r-- 1 root root 1359 Jul 26 11:33 sha512.lua -rw-r--r-- 1 root root 236 Jul 26 11:33 sha.lua -rw-r--r-- 1 root root 698 Jul 26 11:33 string.lua -rw-r--r-- 1 root root 5178 Jul 26 11:33 upload.lua drwxr-xr-x 2 root root 4096 Jul 26 11:33 upstream drwxr-xr-x 2 root root 406 Jul 26 11:33 websocket
