openresty rpm how to get lua modules

grangerx

Hi all,

I am trying to upgrade from using a compiled tar.gz version of openresty to the official RPM package version.

I am trying to use the latest openresty via the RPM file at the official RPM repo. My OS is RHEL 6.x.

I can get the openresty RPM installed no problem, but the script our app developer wrote needs the 'lzmq' module.

Our tar.gz compiled version (compiled by my predecessor who is no longer available) has the lzmq.so file under lualib, but I can't figure out how to get the latest version of that module since we are now using the RPM version.

I see that it can be installed using a luarocks util, but after installing the RPM (EPEL?) version of luarocks, I can't figure out how to configure the /etc/luarocks/* config files to properly allow installation of the module under /usr/local/openresty/site/lualib

Is there a guide somewhere or does someone know the best-practices invocation to get the lzmq module installed in the right place?

Thanks,
Justin

Did you know that this library will block Nginx worker?

Right now it is probably easiest to configure these:

https://github.com/openresty/lua-nginx-module#lua_package_cpath

https://github.com/openresty/lua-nginx-module#lua_package_path

... and use normal LuaRocks and rpm to install stuff you depend on.

(right now, because I'm not sure how opm will change that).

That's interesting. Is there a better library to use? I have seen what looked like at least one other library used in some example code, but it wasn't clear what the name of that library was.

Is there an opm-based zmq module? Last stuff I have found for that was from 2013 and mostly consisted of 'patches welcome!'.

I'm not sure. I think there is nothing that can be considered stable enough. There has been talks about it:

https://github.com/openresty/lua-nginx-module/pull/450 (this in particular will make it really easy to use official 0mq libs)
