Convert the relative path ". I don't see the reason to change. This question is very similar to this can't load module resty. Wellit seems that this is a permission problem. Otherwise it cannot resolve the file path itself. Skip to content.

Then we will start with the four functions that are typically needed for any modulefile. From there we will talk about intermediate level module functions when things get more complicated. Finally we will discuss the advanced module functions to flexibly control your site via modules. All the Lua module functions available are described at Lua Modulefile Functions. This discussion shows how they can be used. All Lmod is doing is changing the environment.
If you try to execute ddt without the module loaded you get:. After the ddt module is loaded, executing ddt now works. If you try checking the environment before loading the ddt modulefile:. The first time we check the environment we find that there is no ddt stored there.
Note that we have shorten the path-like variables to show the important changes. There are also several environment variables which have been set. After unloading the module all the references for ddt have been removed. We can see what the modulefile looks like by doing:. Modulefiles state the actions that need to happen when loading.[Solved] No module named MySQLdb
If the above modulefile is unloaded then the setenv actually unsets the environment variable. That is unload causes the functions to be reversed. The modulefile for ddt shown above contains all the basics required to create one.
Suppose you are writing this module file for ddt version 5. This is the typical way of setting a modulefile up. Namely the package name is the name of the directory, ddtand version name, 5.
We add the lua extension to all modulefile written in Lua. All modulefiles without the lua extension are assumed to be written in TCL. If another version of ddt becomes available, say 5. When a user does module help ddtthe arguments to the help function are written out to the user. The whatis function provides a way to describe the function of the application or library.
Here at TACC we also use that data to provide search capability via the web interface to modules we provide. The four basic functions describe above is all that is necessary for the majority of modulefiles for application and libraries.

This module is a core component of OpenResty. If you are using this module, then you are essentially using OpenResty. This module is not distributed with the Nginx source.
See the installation instructions. This module embeds LuaJIT 2. It is a core component of OpenResty. Since version v0. By leveraging Nginx's subrequests, this module allows the integration of the powerful Lua threads known as Lua "coroutines" into the Nginx event model.
Request contexts are segregated using lightweight Lua coroutines. Loaded Lua modules persist in the Nginx worker process level resulting in a small memory footprint in Lua even when under heavy loads. The possibilities are unlimited as the module allows bringing together various elements within Nginx as well as exposing the power of the Lua language to the user. The module provides the full flexibility of scripting while offering performance levels comparable with native C language programs both in terms of CPU time as well as memory footprint thanks to LuaJIT 2.
It is discouraged to build this module with Nginx yourself since it is tricky to set up exactly right. Note that Nginx, LuaJIT, and OpenSSL official releases have various limitations and long standing bugs that can cause some of this module's features to be disabled, not work properly, or run slower.
And then you can explicitly load the module in your nginx. While building this module either via OpenResty or with the Nginx core, you can define the following C macros via the C compiler options:.
To enable one or more of these macros, just pass extra C compiler options to the. For instance. The openresty-en mailing list is for English speakers. The openresty mailing list is for Chinese speakers. As from the v0. The -bg option can be used to include debug information in the LuaJIT bytecode file:. Please refer to the official LuaJIT documentation on the -b option for more details:.
Note that the bytecode files generated by LuaJIT 2. The support for LuaJIT 2. Attempts to load standard Lua 5. Loading bytecode files via the Lua primitives like require and dofile should always work as expected.
If you want to access the system environment variable, say, fooin Lua via the standard Lua API os. For example. The HTTP 1. So when a HTTP 1. To force curl to send HTTP 1. With LuaJIT 2. You can use the luajit executable to compile.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

So this should be a single character fix :. Hello agentzhI am new to linux and nginx. I have built the nigix with 'lua-nginx-module' and it's displaying following error in niginx error logs. To avoid such troubles, you're recommended to use the OpenResty bundle instead.
Please see. Shawkaine You need to provide enough details like how you setup openresty and the exact error log messages and your nginx.
Otherwise we cannot really help. I found out that my Lua version is 5. I guess that should be one of the reasons that caused the error.
Shawkaine Right. Lua 5. BTW, OpenResty ships with its own lua-cjson by default. Better avoid using your own to prevent any compatibility problems. It should work out of the box. Skip to content.

This library is automatically loaded by default in OpenResty 1. This library is shipped with the OpenResty bundle by default. So you do not really need to worry about the dependencies and requirements. You should use the bundled version of this library in the particular OpenResty release you are using.
Otherwise you may run into serious compatibility issues. This Lua module implements a semaphore API for efficient "light thread" synchronization, which can work across different requests but not across nginx worker processes. See the documentation for this Lua module for more details. This module provides a Lua API to spawn processes and communicate with them in a non-blocking fashion. If the user Lua code is not JIT compiled, then use of this library may lead to performance drop in interpreted mode.
You will only observe speedup when you get a good part of your user Lua code JIT compiled. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:.

Lua Branch: master. Find file. Sign in Sign up. Go back.Module is like a library that can be loaded using require and has a single global name containing a table. This module can consist of a number of functions and variables.
All these functions and variables are wrapped in to the table, which acts as a namespace. Also, a well behaved module has necessary provisions to return this table on require. The usage of tables in modules helps us in numerous ways and enables us to manipulate the modules in the same way we manipulate any other Lua table. As a result of the ability to manipulate modules, it provides extra features for which other languages need special mechanisms.
Due to this free mechanism of modules in Lua, a user can call the functions in Lua in multiple ways. A few of them are shown below. In the above sample code, you can see how flexible programming in Lua is, without any special additional code.
Lua has provided a high level function called require to load all the necessary modules. It is kept as simple as possible to avoid having too much information on module to load it. The require function just assumes the modules as a chunk of code that defines some values, which is actually functions or tables containing functions. Let us consider a simple example, where one function has the math functions. Let's call this module as mymath and filename being mymath. Now, in order to access this Lua module in another file, say, moduletutorial.
In order to run this code, we need to place the two Lua files in the same directory or alternatively, you can place the module file in the package path and it needs additional setup.

When we run the above program, we will get the following output. It is a best practice to return modules for require function and hence the module should be preferably implemented as shown above eventhough you can find other types of implementations elsewhere. Let me now rewrite the same example in the older way, which uses package. This was used in Lua versions 5. The mymath module is shown below. When we run the above, we will get the same output.
