Nginx Lua集成Kafka

第一步：進入opresty目錄

[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]#  

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]# 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  

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?。。?！

下面看看resty里面有些說明呢？？？？

[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   #這是我們自己導入的  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  

這里我們看到了熟悉的mysql.lua和redis.lua，好了其他的先不要管
