Issue during Redmine installation - centos

We have a Redmine instance on the centos 7 server with Bitnami. I am getting following error during installation of an another Redmine instance.
Command Used:
[root#localhost htdocs]# bundle install --without development test
Error Message:
An error occurred while installing mysql2 (0.3.21), and Bundler cannot continue.
Make sure that gem install mysql2 -v '0.3.21' succeeds before bundling.

The Bitnami installer includes a ready to use Redmine stack, so I assume you're trying to install additional plugins on the vanilla Redmine install.
I suspect that you forgot to load the proper environment variables to use the Bitnami Stack mysql libraries. Go to your install directory (usually /opt/bitnami/redmine) and execute this source ./use_redmine
And then follow this instructions https://docs.bitnami.com/installer/apps/redmine/#install_plugins

Installing MySQL Client 5.6 on Ubuntu 18.04

I have a legacy project that I'm trying to modernize, and part of that involves setting up a more efficient system of automated backups using mysqldump.
The app's database is using MySQL 5.6, and is hosted via an RDS instance. To get mysqldump up and running, I believe I need to install a version of mysql-client that corresponds to 5.6.
However, running apt-get install mysql-client installs 8.0 by default. However, I can't find any version-specific versions of mysql-client available. Running sudo apt-get install mysql-client-5.7 returns a notice that there's no installation candidate available.
Is it still possible to install older versions of mysql-client? If not, is there another way to get ahold of the mysqldump functionality?
Edit: As #exussum noted below, 8.0 is backwards compatible with 5.6 and 5.7. I was hitting errors when running mysqldump, which I'd assumed indicated incompatibility, but were actually related to my app specifically.
They are backwards compatible, so you can use mysql-client 8 to dump mysql-server 5.5
to get a specific version docker is great
(sudo apt install docker) to install
docker run mysql:5.6 mysqldump
will run mysqldump though docker, and you can choose your version there easily enough

How to fix "Nothing to do" error on openproject configure?

I am installing OpenProject 8.3.1 on my apache 2.4 CentOS7 WHM/CPanel VPS using packaged installation and I've run into the following problem:
When I run openproject configure right after installation process it goes well up until the line "No package mod_ssl available". Followed by "Error: Nothing to do". Openproject can't be accessed.
I'm using PostgreSQL and auto installation/configuration option. I've tried skipping all but the most essential options in configuration, to no help.
The mod_ssl unavailable bit is the most surprising, since after I run rpm -qa|grep mod_ssl I get "ea-apache24-mod_ssl-2.4.38-3.3.1.cpanel.x86_64" - meaning I in fact do have mod_ssl available.
It looks like you are using a non-standard CentOS edition with CPanel. I don't think OpenProject can be installed on such a distribution, because it seems to come with limitations as to what packages are available. The mod_ssl package you mention is the one originally distributed by the CentOS distribution.

Install Nagios plugins - missing install instructional step?

I have Nagios XI installed and want to monitor remote Redhat machine using SSH. Installing the agent is likely not allowed in our environment.
This is from Nagios instruction from the page 2
Before you can use the check_by_ssh plugin, you must install/configure the following on the remote Linux/Unix server you want to
monitor:
● Create a nagios user
● Install Nagios plugins and/or monitoring scripts
● Install and configure the SSH daemon
I downloaded the Nagios official plugins(I believe there are 50 plugins) and extracted the files, but there is no instructional step for install command. I read the README file, but this seems to give me the steps of making the install files from the source, I think.
Is there a simple command that will run the install in order for me to install the plugins that will include check_by_ssh plugin?
This answer was given by Nagios support team:
Nagios Plugin Installation
cd /tmp/nagios-plugins-2.1.2
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install

Exception: Failed to solve dependencies: 1:perl-JSON-XS-2.27-2.el6.x86_64 requires perl(:MODULE_COMPAT_5.10.1)

Scenario: new installation of plesk 12.5 on centOS 7 into an OpenVZ container (proxmox):
Installing Plesk 12.5 I get the following error:
Exception: Failed to solve dependencies: 1:perl-JSON-XS-2.27-2.el6.x86_64 requires perl(:MODULE_COMPAT_5.10.1)
any tips?
You mention CentOS 7, but the package you are attempting to install (perl-JSON-XS-2.27-2.el6.x86_64) is for RedHat/CentOS 6, denoted by the el6 tag in the package name.
In any case, the issue appears to be due to not having the correct repositories available in yum to solve all necessary dependencies. Plesk maintains their own yum repositories to provide all of the necessary packages. Usually the install script will handle this for you (the install script is just a quick way to obtain the Plesk autoinstaller which should have the proper source repository configured).
I would suggest you examine the currently configured yum repositories in your container and make sure there are no conflicting repositories. Depending on the components you are installing with Plesk, it will want to manage nginx, apache, mysql, php, and some perl components so make sure you do not have yum repositories attempting to install related packages. Also, if you are indeed using CentOS 7, make sure you have no repositories attempting to install CentOS 6 packages. This bash one-liner should print out all the configured yum repository URLs so you can quickly scan if any are using the wrong version:
grep -re '^\(mirrorlist\|baseurl\)' /etc/yum.repos.d/
If you need further troubleshooting help, please include how you are attempting to install Plesk.

unable to install pg-native (libpq-dev) on ubuntu 14.04

I'm trying to install https://github.com/brianc/node-pg-native on a container.
Looks like I've to install postgresql (server) to install libpq-dev. I don't want to install postgresql server on a container, as it has to only connect to server.
I tried installing on postgresql-client but no use. I'm using ubuntu:14.04 . Any suggestions?
If I'm doing something completely please wrong let me know.
libpq-dev doesn't install the full server but does install a lot of development dependencies. The pg-native node module doesn't supply pre built binaries so you need to install all the dev dependencies for npm to complete the build for you.
If you are concerned about your image size, it is possible to build the node module in a build container with all the build dependencies to create a tar.gz of it. Then extract the built package into your app instead of using npm install. This can be done generally for all node modules to speed up your build process and remove all build tools from the docker image you run the application from.
