我正在尝试从 HAProxy 加载 Lua 脚本。在 Lua 脚本中，以下行导致错误：
local http = require("socket.http")
最初我收集自journalctl -xe输出表明该库未安装。我安装它使用luarocks install luasocket。这并没有解决问题。新的错误是module "socket.http" not found。继此评论之后post https://stackoverflow.com/questions/47124011/how-to-load-3rd-party-lua-libs-installed-via-luarocks-into-haproxy我意识到我必须更改 Lua 库路径的设置才能解决此问题。
现在，我想了解以下内容：
- 我是否已从源代码安装HAProxy+Lua并修改安装前的库路径？
- 如果不需要从源代码构建，那么我相信我必须使用以下命令更改路径
syslog正如上面链接的帖子的评论所建议的。如果是这种情况，我该怎么做以及我需要更改/添加哪些设置syslog.conf?
- 还有其他我忽略的解决方案比上述任何解决方案更容易吗？
提前感谢您的帮助。

我已经修改了两个LUA_PATH and LUA_CPATH如下：

我仍然遇到与之前报告的相同的错误。
EDIT 2
找到了这个post https://www.lua.org/pil/8.1.html对Lua require 函数相当有帮助。经过讨论，我尝试了以下方法：
package.path="/usr/share/lua/5.3/?/?.lua"
package.cpath="/usr/lib64/lua/5.3/?/?.so"
我在导致错误的 lua 脚本顶部添加了这些行。我还修改了环境变量，LUA_PATH and LUA_CPATH具有相同的值。错误仍然存在。
现阶段我没有所有可能的选择，如果有人能够阐明这个问题，我将很高兴。
