Location of sphinx-build on CentOS - centos

I have a brand new CentOS 6 box and wanted to install sphinx, in order to compile documents as generated by readthedocs.org i.e. rst files.
In a previous ubuntu box I was running
make html
and that would invoke the
sphinx-build
command and compile the documentation.
I downloaded the latest version of sphinx and installed it as such:
sudo wget http://sphinxsearch.com/files/sphinx-2.1.9-1.rhel6.x86_64.rpm
sudo localinstall sphinx-2.1.9-1.rhel6.x86_64.rpm
Everything seems to be fine but sphinx-build is nowhere to be found.
Any pointers are more than appreciated.

You are mixing up two different tools named Sphinx: the full text search server (http://sphinxsearch.com/) and the documentaton generator (http://sphinx-doc.org/). You need the latter tool in order to compile documents usingsphinx-build.

You can also install rpm package of sphinx (Python documentation generator) with yum at CentOS 6 using:
yum install python-sphinx.noarch
at Fedora 20 using:
yum install python-sphinx-doc.noarch

A short addup, according to offical document, one just need to run
pip install Sphinx to install the python documentation generator, sphinx. Or it can be downloaded from distribution package.

Completely uninstall Eclipse 4.7 version in RHEL 7.4 Maipo

I'm trying to uninstall the current version of Eclipse IDE in my RHEL machine by simply deleting all the files like:
sudo rm -rf ~/.eclipse
sudo rm -rf ~/eclipse-workspace
I also tried
sudo yum remove 'eclipse*'
However, these didn't seem to solve the purpose.
Any help will be appreciated, thanks!
Applications on Linux systems are most often installed using so-called packages, which are managed by a package management system. In the case of RHEL, packages use the RPM format, and the package manager of choice is a tool called yum.
Both installation and removal of software (packages) should be done using yum, so as to allow the package management system keep track of all installed files and current status. Therefore, you shouldn't try to remove software by simply deleting files from the file system. Instead, use the yum command. See the RHEL System Admin Guide for a detailed explanation of how to use yum to search, install, upgrade, and remove packages: Working with Packages.
You have tried the correct command (yum remove <package-name>), but you need to use the correct package name. On RHEL 7.4, the latest version of Eclipse is available as a part of the DevTools channel, and the package name is rh-eclipse47 (see Enabling the Red Hat Developer Tools Repositories). Note that you may have also installed an older version, which would be, for example, rh-eclipse46.
To find out what is the name of the package you have installed, you can run, for example, the following command:
yum list installed | grep eclipse
There is also the possibility that you installed the software not from an RPM package but manually, e.g. from a .tar.gz file distrubuted from eclipse.org. If that's the case, you will need to use the uninstaller program supplied with that distribution of the software.
Write command as:
rpm -qa|grep eclipse
This will give a list of installed packages. Remove all the packages by giving below command:
rpm -e *package-name*
Done!!!

How Do I install specific version of monit on redhat linux

"Yum install monit" command by default will install 5.14 version. But Monit has released till 5.20 version
I tried with the below command for available packages
sudo yum --showduplicates list monit | expand
It shows up only one available package
Available Packages
monit.x86_64 5.14-1.el6
Are there any other option apart from manually downloading the tar using wget command and then installing it.
There used to be an RPM on the rpmforge/repoforge repos although these are presently down.
I believe these might resurface (based on this https://github.com/repoforge/rpms/issues/375) but in the mean time unless you want to build your own RPM for it you could grab this from a mirror.
Such as:
yum install https://www.insaneworks.co.jp/pub/el6/RPMS/x86_64/monit-5.20.0-1.el6.x86_64.rpm

Centos - how do I install a specific version of Erlang?

I'm running Centos 6.7 on my server and am trying to install Erlang/Rabbitmq following these instructions:
Erlang Installation
RabbitMQ Installation
The trouble is that at time of writing these install Erlang 19.0 with RabbitMQ 3.6.3, which leads to a pretty major bug as far as my client who occasionally looks at the management interface to monitor queues is concerned.
The guidance in the error ticket is not to use erlang 19 until RabbitMQ 3.6.4 is released. But how can I install a specific version of Erlang?
These steps worked for me:
Go to the download page here: https://packages.erlang-solutions.com/erlang/
Select your appropriate package -- you can copy/peek the link then download it using wget.
Install it using rpm.
Example:
# Download erlang 19
$ wget http://packages.erlang-solutions.com/site/esl/esl-erlang/FLAVOUR_1_general/esl-erlang_19.0~centos~7_amd64.rpm
# Install
rpm -Uvh esl-erlang_19.0~centos~7_amd64.rpm
You can always build install from source.
Go to the Erlang.org Downloads page, pick your version from the right side.
From there you can follow the instructions. Although they are for Ubuntu, the commands are the same except for the dependencies part where you can use the command below to install what you need:
sudo yum install g++ openssl-devel unixodbc-devel autoconf ncurses-devel
Another option would be to use kerl, which is similar to rvm in some sense and very (very!) easy to use. It will let you install different Erlang versions and switch between them any time you want.
I prefer this approach instead of looking up packages myself (with possible incompatibilities in the dependencies required) or downloading and compiling everything myself every time I want to try a new Erlang version.

How to run PHP 5.5.4 mcrypt run on CentOS 6.4?

I am getting the following error:
PHP Warning: PHP Startup: Unable to load dynamic library
'/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so' -
/lib64/libc.so.6: version `GLIBC_2.14' not found (required by
/usr/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so)
Does mcrypt require glibc 2.14?
We are running CentOS 6.4 (latest stable version of CentOS) and it comes with glibc 2.12 (can't really upgrade glibc as being a core part of OS, changing it will likely break lots of stuff)
How do I make my PHP 5.5.4 run mcsypt under these circumstances?
Current configuration (phpinfo output) is here.
I was also having issues installing mcrypt on my VPS dev server so I thought I would post my solution in the hopes that it helps someone. I am running Centos OS 6.5 and had upgraded PHP to 5.5.13 using the Webtatic EL yum repository. https://webtatic.com/packages/php55/
First shh into your server
ssh admin#domain.com
initially I was trying to do (which was not working):
yum update
yum install php-mcrypt
I then realized my mistake when I looked at php -v and realized php-common was conflicting as the above code was trying to load a dependency from 5.3.
I then executed the following correct commands:
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
yum update
yum install php55w-mcrypt
service httpd restart
This worked perfectly for me.
I also read while researching this issue that some people did have to add the extension to their .ini file manually by adding the following line but i did not have to do this.
extension=mcrypt.so
you can find the location of your php.ini file by looking at phpinfo(); and see which configuration it is loading. For me the following ini files were loading:
/etc/php.ini
/etc/php.d/mcrypt.ini
/var/www/vhosts/system/domain.com/etc/php.ini
If the installation is successful then you will see the extension when you echo phpinfo();
Try installing php-mcrypt using yum. That should pull in any other libraries you need to run it.
yum install php-mcrypt
In light of your update, it would appear that you are trying to use the MCrypt extension built from another PHP Source which was created by an updated GLIBC library. The only proper solution I can see is the following:
You first need to ensure you have libmcrypt, libmcrypt-devel, and mcrypt installed before continuing. Check your CentOS repository.
Download the PHP Source from http://php.net
Untar the downloaded source tar -zxf php-5.5.4.tar.gz
cd into the source cd php-5.4.4
Copy your current ./configure string. The whole thing!
Add support for Mcrypt --with-mcrypt=/usr and run the new configure command
make && make install
restart Apache and PHP-FPM
This will keep your current configuration just as CentOS has built it but with the additional support of MCrypt as you are looking to have. Once you've done this, you do not need to enable the MCrypt extension in your php.ini file as it will be built into PHP itself and will be automatically loaded for you now.
When in doubt, you can also read up on the installation here http://us1.php.net/manual/en/mcrypt.installation.php

Installing PDO-drivers for PostgreSQL on Mac (using Zend for eclipse)

How can I get PDO to work on my mac (os x 10.5)? I'm using the built in php and php in Zend/Eclipse. Can't seem to find useful drivers for it at all.
I had to install the PDO_PGSQL driver recently on Leopard, and I ran across a multitude of problems. In my search for answers, I stumbled across this question. Now I have it successfully installed, and so, even though this question is quite old, I hope that what I've found can help others (like myself) who will undoubtedly run into similar problems.
The first thing you'll need to do is install PEAR, if you haven't done so already, since it doesn't come installed on Leopard by default.
Once you do that, use the PECL installer to download the PDO_PGSQL package:
$ pecl download pdo_pgsql
$ tar xzf PDO_PGSQL-1.0.2.tgz
(Note: you may have to run pecl as the superuser, i.e. sudo pecl.)
After that, since the PECL installer can't install the extension directly, you'll need to build and install it yourself:
$ cd PDO_PGSQL-1.0.2
$ phpize
$ ./configure --with-pdo-pgsql=/path/to/your/PostgreSQL/installation
$ make && sudo make install
If all goes well, you should have a file called "pdo_pgsql.so" sitting in a directory that should look something like "/usr/lib/php/extensions/no-debug-non-zts-20060613/" (the PECL installation should have outputted the directory it installed the extension to).
To finalize the installation, you'll need to edit your php.ini file. Find the section labeled "Dynamic Extensions", and underneath the list of (probably commented out) extensions, add this line:
extension=pdo_pgsql.so
Now, assuming this is the first time you've installed PHP extensions, there are two additional steps you need to take in order to get this working. First, in php.ini, find the extension_dir directive (under "Paths and Directories"), and change it to the directory that the pdo_pgsql.so file was installed in. For example, my extension_dir directive looks like:
extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20060613"
The second step, if you're on a 64-bit Intel Mac, involves making Apache run in 32-bit mode. (If there's a better strategy, I'd like to know, but for now, this is the best I could find.) In order to do this, edit the property list file located at /System/Library/LaunchDaemons/org.apache.httpd.plist. Find these two lines:
<key>ProgramArguments</key>
<array>
Under them, add these three lines:
<string>arch</string>
<string>-arch</string>
<string>i386</string>
Now, just restart Apache, and PDO_PGSQL will be up and running.
Take a look at this PECL package: PDO_PGSQL
I haven't tried it myself, but I've been interested in playing with Postgres as an alternative to MySQL. If I have a chance to try it soon, I'll throw my results up here in case it helps.
I'm not sure this will help with the PDO drivers specifically, but you might look into BitNami's MAPPStack.
I had a ton of trouble with Postgres, PHP, and Apache on my Mac, some of it having to do with 64- vs 32-bit versions of some or all of them. So far, the BitNami MAPPStack install is working nicely in general. Maybe it will help with your PDO issues as well.
Install new php version via brew and restart server, and php -v, all issues are removed.
This is what worked for me
brew install php55-pdo-pgsql
This installs PHP 5.5.32 and PostgreSQL 9.5. I already had PostgreSQL 9.4 installed so I uninstalled the homebrew version with:
brew uninstall postgres
You then have to update /etc/apache2/httpd.conf to point to the correct PHP version and restart Apache:
LoadModule php5_module /usr/local/Cellar/php55/5.5.32/libexec/apache2/libphp5.so
My OSX version is Yosemite.
