I want to install mysql v5.5.27 and php v5.3.15 but opscode doesn't show how to do this.
I've checked the recipes and saw the attributes and modified them but still no results.
Is there a way to force this?
Thanks in advance!
For PHP, if you want to install a different version from what is what is available in the distribution's official repository, you can use the compile from source install method instead of package (default).
Simply change default['php']['install_method'] to 'source' and run the default recipe. Alternatively explicitly run php::source ;-)
NOTE: You also need to change the default['php']['url'], default['php']['version'], default['php']['checksum'], etc to suite your needs.
For MySQL, as Mark said, it is up to the distribution (the version from its repository), looking at the mysql::server there isn't easy way to change it, as there is no such option as PHP (install by compiling from source) like the PHP cookbook.
The cookbook only has logic for choosing the version when installing on windows. On Linux the cookbook simply installs the mysql package supported by the package repositories associated with your distro.

When I try to run any Go script it show me this error
I installed go lang step by step from this link
https://www.tecmint.com/install-go-in-linux/
When I setup go script like this
go get github.com/tomnomnom/waybackurls
I got error like this
github.com/tomnomnom/waybackurls
src/github.com/tomnomnom/waybackurls/main.go:191: u.Hostname undefined
(type *url.URL has no field or method Hostname)
If you are following the guide you linked by copy-pasting commands, you will have installed Go 1.7.3. The function url.Hostname() was added in Go 1.8.
I suggest completely ignoring that guide. Remove /usr/local/go, remove ~/go_projects and undo the path related stuff.
Instead, use the package manager of your OS to install Go.
Most likely, this means you should do either sudo apt install golang (for Ubuntu, Debian, ...) or sudo dnf install golang (Fedora, CentOS, ...).
That will give you the latest version that is supported by distro maintainer (which at the moment is probably 1.11 or 1.12, depending on your distro).
As an alternative to the packagemanager, download the latest version from https://golang.org/dl/.
This approach also gives you an installation that follows the Go ecosystem their conventions for paths (I'm not sure if ~/go_projects was ever a think, but it isn't today).
How would I install things on Pepper, since I don't know what package manager it uses. I usually use apt on my Ubuntu machine and want to install some packages on Pepper. I'm not sure what package manager Pepper has (if any) and want to install some packages, but also only know the name of the package using apt (not sure if the package name is the same on other package managers). And if possible, would I be able to install apt on Pepper. Thanks.
Note: From the research I've done, Pepper is using NaoQi which is based off Gentoo which uses portage.
You don't have root access on Pepper, which limits what you can install (and apt isn't on the robot anyway).
Some possibilities:
Include your content in Choregraphe projects - when you install a package, the whole directory structure is installed (more exactly, what's listed in the .pml); so you can put arbitrary files on your robot, and you can usually include whatever dependencies your code needs.
Install python packages with pip.
In NAOqi 2.5, a slightly older version of pip is installed that will not always work out of the box; I recommend upgrading it:
pip install --user --upgrade pip
... you can then use the upgraded pip to install other packages, using the upgraded pip, and always --user:
/home/nao/.local/bin/pip install --user whatever-package-you-need
Note however that if you do this and use your packages in your code running on Pepper, that code won't work on other robots until you do pip on them, which is why I usually only do this for tests; for production code I prefer packaging all dependencies in my app's package.
As a workaround if you need to install software (or just newer versions of software) using Gentoo Prefix is an option.
Gentoo Prefix builds a Gentoo OS on any location (no need of root, can be any folder). It includes it's own portage (package manager) to install new software.
I maintain a few projects to work with Pepper and use "any" software I want. Note that they are built for 64b (amd64) and 32b (x86) even though for Pepper only the 32b matter.
gentoo_prefix_ci and gentoo_prefix_ci_32b Which builds nightly the bootstrap of the Gentoo Prefix system. This is a process that takes a while to compile (3-6h depending on your machine) and that breaks from time to time (as upstream packages are updated and bugs are found, Gentoo is a rolling release distribution). Every night updated binary images ready to use can be found in the Releases section.
For ROS users that want to run it on the robot, based on the previous work, I maintain also ros_overlay_on_gentoo_prefix and ros_overlay_on_gentoo_prefix_32b. They provide nightly builds with binary releases of ROS Kinetic and ROS Melodic over Gentoo Prefix using ros-overlay. You can find ready-to-use 'ros_base' and 'desktop' releases.
For purposes related to the RoboCup#Home Social Standard Platform League where the Pepper robot is used I also maintain a specific build that contains a lot of additional software. This project is called pepper_os and it builds 270+ ROS packages, a lot of Python packages (250+ including Theano, dlib, Tensorflow, numpy...) and all the necessary dependencies for these to build (750+ packages). Note that the base image (it's built with Docker) is the actual Pepper 2.5.5.5 image, so it can be used for debugging as it if it was in the real robot (although without sensors and such).
Maybe this approach, or these projects, are useful.
The package manager on pepper is disabled. But you can copy the files to the robot and write your own service that imports any package you might need.
As a supplement on importing:
http://www.about-robots.com/how-to-import-python-files-in-your-pepper-apps.html
To get rid of error :
" SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
".
If you use python and requests package, just add verify=False at the end of your parameters.
r=requests.get(URL,params,header,verify=False)
Works with my Pepper
To get rid of
InsecurePlatformWarning: A true SSLContext object is not available.
install
/home/nao/.local/bin/pip install --user requests[security]
To get rid of:
CryptographyDeprecationWarning: Support for your Python version is deprecated.
install
/home/nao/.local/bin/pip install --user cryptography==2.2.2
If it based on Gentoo maybe we could try to install portage with pip.
pip install portage
Just a thought.
Jython Package installation issue, using pip
Hi, I have installed Jython2.7 configured with pydev in eclipse neon, also configured python 3.6 package
I am able to install packages for python using pip installer?
pip install "packagename"
Below are some of the packages in python/Lib/Site-packages directory
I was able to install all the packages
How do I use pip installer to install packages for jython?
I tried to install Jip package with
jython install setup.py
The binary File got installed in the Jython/Lib/Site-packages folder
However, I am not able to use it.
where and how do I get Jython package binaries like jip?
Also, Please let me know how to search jython packages?
Also, How to make pip install library packages in jython?
Any other configuration like jython home, etc that should be made?
This answer is going to be really generic but I just recently have slogged my way through the setup for jython/jip/pip and here's roughly what I had to do.
Firstly, I'm running Windows 7 64 Bit from behind a proxy (work machine.)
Had to install jython 2.7.0 instead of 2.7.1 because (I think anyway) 2.7.1 requires admin privileges which I don't have on my work PC.
Pip didn't install correctly during the Jython installation and I spent an obscene amount of time trying to get it installed and functioning as I knew it from my cpython days. NOTE: Just because you get pip installed, doesn't mean you can use any package on a python package repo. As of 2.7.0, Jython doesn't have end to end capability to interpret/compile some libraries that rely on certain python wrappers of native OS function calls. I believe 2.7.1 makes solid progress in the direction of supporting all needed native calls but don't quote me on that. For example, I tried to use wxPython to make a simple GUI to test my jython install. Trying to install it from pip kept causing really non-specific error info that took me a lot of time to figure out that the cause was jython simply couldn't compile the wxPython source so beware.
I had to set environment variables 'http_proxy' and 'https_proxy' in the form of http://proxyhosturl:port and https://proxyhosturl:port respectively to get out from behind the proxies without having to invoke pip with the proxy switch every time I called it.
To actually install pip, have a look here. These instructions are for Python and Linux/Unix but the principle is roughly the same. Just use jython -m instead of python -m and ignore the '$' at the start of each command line.
Also be sure to CD to your python_home/bin folder when invoking the ez_install exe.
If that doesn't work (didn't for me), try using get-pip.py script with these instructions https://pip.pypa.io/en/stable/installing/ (remember jython instead of python etc.). Download it, cd to the download location and follow the noted install steps. Worth noting is about half way down the install instructions where it details installing from local archives (source/binary zip or tar.gz archives of pip and setuptools as better described here: https://packaging.python.org/tutorials/installing-packages/#installing-from-local-archives).
The links to the bin archives of pip and setuptools are here:
https://pypi.python.org/pypi/setuptools
https://pypi.python.org/pypi/pip
It may also be worth making sure that your PATH environment variable has the jython/bin path in the variable value. The jython installer should do this but, again, mine did not.
If all goes well, you should be able to invoke pip with the --version switch and if it prints a line with the installed pip version info then you should be good to go
Another quirky issue I had was I could invoke a function of pip one time and any subsequent times I would get a stack trace ending with something along the lines of an object not having a certain property. I fixed that by finding my temp directory by opening a windows explorer instance and typing %TEMP% in the address bar and hitting enter, it should take you to a subdir of your AppData folder and there you may see a folder with the name of the package you were trying to install and the text "_pip" somewhere in the directory name. Delete the directory and try the pip install command again. I had to do this + invoke pip install pip -U to update my install to the latest version. Then pip began behaving correctly in my instance.
pip search numpy (or your library name) will generate a list of results with the same logic it uses to locate your desired package when you call pip install but, again, just because it returns a matching package doesn't mean it will compile when you install it (numpy doesn't work because of the missing java to C native function calls I described earlier.) The trade off is that you can import code artifacts from Java JAR files in your Jython script files and leverage their functionality with relative ease. Between the public Java APIs available and the python packages that work with the jython interpretor, you can (in my experience) come up with a way to accomplish your task. See the following info on JIP, Maven and IDEs.
IDE and jython integration (Eclipse)
- If you are stuck using Eclipse (like me) it actually has pretty decent support for python development. Install the PyDev plugin for Eclipse from Help -> Install Software. Put in this URL https://marketplace.eclipse.org/content/pydev-python-ide-eclipse, hit tab, and select the PyDev plugin and hit 'finish.'
- Setup the jython interpretor info from Windows -> Preferences -> PyDev. Provide the path to your jython.jar file.
- You should now be able to use File -> New PyDev project to create a basic python project and configure it to use your version of Jython and Java.
Brief Overview of Jip and Maven
- jip is a jython package that is invoked very similarly to pip but instead will download JAR files from the Maven Central Repository instead of python packages from pypi.com, for example. See the install instructions described here. Note the install procedure for a global jip install which differ from just pip install jip. https://pypi.python.org/pypi/jip/
- I never got jip to work exactly as I wished because there's not a ton of documentation on it outside of what I already linked. However, if you install a JAR using jip, you have to go to your project in Eclipse and actually add the JARs themselves to your PYTHONPATH in order for import statements and editing to have intellisense and so that you don't get a classnotfound exception at runtime. See following screen shot.
- There is a JIP config file that you can use similar to the pip config ini file but I have yet to find any exhaustive documentation on it's setup.
Note in the above screen shot the first entry in the External libraries entries. By default, pip places installed packages in that directory so to enable eclipse to find them, you need to also ensure that location is entered.
In Conclusion
- I have more to add to this answer and I will do so as soon as possible. In the meantime, see this example project I've loaded into github.
https://github.com/jheidlage1222/jython_java_integration_example
It shows basic config and how to interface with JARs from python code. I used the apache httpcomponents library as an example. Good luck amigo.
I have found this DNSimple ansible module:
http://docs.ansible.com/ansible/dnsimple_module.html
but can not find anywhere on that page to download and install it? How do I go about downloading and installing ansible modules like this. Thanks.
The accepted answer solved the questioner's problem but didn't address the broader scope of the question.
How to install an Ansible module? The documentation is currently vague as to how to achieve this simple requirement!
An excellent general guide to writing modules (I've no connection to the author) can be found here.
The quickest way is to simply have a folder called library/ in the same folder as your playbook. Inside this folder, place the python script for the Ansible Module. You should now have a corresponding task available to your playbook.
If you want to share your module across multiple projects, then you can add an entry to /etc/ansible/ansible.cfg pointing to a shared library location, eg:
library = /usr/share/ansible/library
The module itself is part of ansible since version 1.6 (as stated here). To use it, you need to have dnsimple on your host machine (also stated in the above description). Install it with sudo pip install dnsimple
It is important to know that base ansible modules are not installed by default on devel version, which is the default installed version when you build from source.
Only few modules are present for developpment purpose.
So when you'll run your playbook it'll complain about not found module with following error message
couldn't resolve module/action 'xxx'
If you have no choice but building for source, don't forget to checkout the stable branch to install all basic ansible modules!
The latex file is giving the following error:
! LaTeX Error: File `datetime.sty' not found.
Here is the Latex code: \usepackage{datetime}
Am I missing something?
I am using Debian 3.1 Linux Machine.
I don't use Debian myself, but if I look it up, Debian contains it in the package 'texlive-latex-extra'. If you installed LaTeX via the packet-manager of debian (I think so) the command 'apt-get install texlive-latex-extra' executed as root should install you the needed file. Alternatively you can use a graphical package-manager to install the package.
If your LaTeX Distribution does not load the package automatically, you can try to install it manually according to the readme file here: http://www.ctan.org/pub/tex-archive/macros/latex/contrib/datetime/ Edit: http://www.ctan.org/pkg/datetime
Yes, you are missing the datetime.sty file; you are probably missing the whole package too. What system are you using for managing your (La)TeX installation ? If you tell us you may get more specific advice than I can give.
You need to get the datetime package from CTAN or one of its mirrors and install it into your local texmf tree. Your LaTeX manager will do this for you. You may also be able to configure your LaTeX manager to automatically download and install packages the first time they are requested.
