How to install MySQL in Fedora20?
Fedora uses the MariaDB fork of MySQL. It's a drop in replacement for MySQL.
To install the server package, run the following as root:
# yum install mariadb-server
To start the server, run the following as root:
# systemctl start mysqld.service
To enable the server to start on boot, run the following as root:
# systemctl enable mysqld.service
and how to open mysql prompt after installation using guest user.
This response to the second part of your question, assumes that you have already installed the server package as above, and started it, and want to connect to that server:
First, install the client package. Run the following as root:
# yum install mariadb
Then run the client (prompt), by invoking the following:
$ mysql

Problems installing MySQL 5.7 properly on fresh CentOS 7 install

I admit that I am new to back-end work in general and I seem to be stuck (for several hours) following through with completing the setting up process for Magento 2.3
I was following https://devdocs.magento.com/guides/v2.3/install-gde/prereq/mysql.html for my commands but to no success.
I managed to get the following installed:
Cent OS 7 (x86_64)
Apache 2.4.6
PHP 7.2.14 (all the extensions installed passed the Setup Wizard readiness check)
I used these commands to install MySQL 5.7 Community Release: (from the documentation)
wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum -y install mysql mysql-server
yum -y install mysql-community-server
To check if my installation went well, when I run:
mysql --version
I received an error message saying:
-bash: /usr/bin/mysql: No such file or directory
I know that there is something I definitely am missing out completely. When I try to start the MySQL service using the command:
systemctl start mysqld
I get the resulting error message:
Failed to start mysqld.service: Unit not found.
Any suggestions will much be appreciated. Thank you in advance.
Maybe it installed it as mariadb?
systemctl start mariadb
After removing MySQL 5.7 community release from my Cent OS, I decided to install MariaDB.
Inside the directory /etc/yum.repos.d/ I've created a file called MariaDB.repo and added this into the file:
# MariaDB 10.3 CentOS repository list - created 2019-01-25 05:36 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
I then performed the command in my terminal window:
sudo yum install MariaDB-server MariaDB-client
Because of this, mysql --version and systemctl start mysql works like a charm. Thanks #greenberet123 and #danblack for the suggestion.

How can i remove instance of mysql from brew info mysql

I am trying to remove mysql from my macbook pro to start from fresh.
I have followed guides on how to remove all instances and files of mysql, however if i run
brew info mysql
I still get info pertaining to mysql 8.0 as follows:-
mysql: stable 8.0.12 (bottled)
Open source relational database management system
https://dev.mysql.com/doc/refman/8.0/en/
Conflicts with:
mariadb (because mysql, mariadb, and percona install the same
binaries.)
mariadb-connector-c (because both install plugins)
mysql-cluster (because mysql, mariadb, and percona install the same
binaries.)
mysql-connector-c (because both install MySQL client libraries)
percona-server (because mysql, mariadb, and percona install the same
binaries.)

mysql is already uninstalled. See these lines in the middle of your output:
Not installed
From: https://github.com/Homebrew/homebrew-
core/blob/master/Formula/mysql.rb
Homebrew is fetching this information on mysql's dependencies and usage remotely from GitHub. I do not have mysql installed either and get the same output when I run brew info mysql. If you try running mysql from the command line, you should get -bash: mysql: command not found.

Maria DB (mysql) installation on Red Hat . How do I start service after installation

I have installed mysql (maria db) on redhat.
My question is - how do I start and stop the server?
STEPS
I ran the command
$sudo yum install mysql
It gave long messages in the console while installing and and at the end said

But now when I run the command
$ sudo service mysql start
it gives messages
Redirecting to /bin/systemctl start mysql.service Failed to issue

directory.
I am using Red hat version - Red Hat Enterprise Linux Server release 7.1 (Maipo)
I believe you've installed only the client. For the server do yum install mariadb-server. The package will install appropriate service file for you.
The name of the service though is mariadb. Well that is the case on CentOS 7 at least... So, after you install mariadb-server package do systemctl enable mariadb and systemctl start mariadb.
The service is called mysqld, not mysql. So:
$ service mysqld start
Or better yet, use the proper systemd syntax:
$ systemctl start mysqld

MySQL: Package 'mysql-server' has no installation candidate

This error is being shown whenever I want to install any software via command line.
Even if i try to install softwares which I know are present at the source from where I am downloading.
Below is the full error message i am getting :
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package mysql-server is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'mysql-server' has no installation candidate
It worked for me.
If you have followed all the previous steps successfully and after running sudo apt-get install mysql-server you are getting an error then try this
sudo apt-get install mariadb-server
I experienced this issue when trying to install MySQL Server on Debian 10.
Here's how I fixed it:
The issue is caused by the MySQL server apt repository not being included in your system's software repository list. In Debian 10 for example, MariaDB, a community fork of the MySQL project, is packaged as the default MySQL variant.
So to fix this first, add the MySQL server apt repository to your system's software repository list. Follow these steps:
Go to the download page for the MySQL APT repository at:
https://dev.mysql.com/downloads/repo/apt/
Select and download the release package for your Linux distribution. You can use:
sudo wget https://the-download-link
In my case it was:
sudo wget https://dev.mysql.com/get/mysql-apt-config_0.8.15-1_all.deb
Install the downloaded release package with the following command, replacing version-specific-package-name with the name of the downloaded package (preceded by its path, if you are not running the command inside the folder where the package is):
sudo dpkg -i version-specific-package-name.deb
In my case it was:
sudo dpkg -i mysql-apt-config_0.8.15-1_all.deb
Note: dpkg is used to install, remove, and inspect .deb software packages. The -i flag indicates that we’d like to install from the specified file.
During the installation, you’ll be presented with a configuration screen where you can specify which version of MySQL you’d prefer, along with an option to install repositories for other MySQL-related tools. The defaults will add the repository information for the latest stable version of MySQL and nothing else. This is what we want, so use the down arrow to navigate to the Ok menu option and hit ENTER.
You'll also be asked to select a repository to add. Choose 'debian buster' which has the package 'mysql-server' in it. After the adding this repository you can update the repository and use the below command to install MySQL.
sudo apt-get install mysql-server
The package will now finish adding the repository. Refresh your apt package cache to make the new software packages available:
sudo apt update
Note: If you ever need to update the configuration of these repositories, just run sudo dpkg-reconfigure mysql-apt-config, select new options, and then sudo apt-get update to refresh your package cache.
Install MySQL by the following command:
sudo apt-get install mysql-server mysql-client libmysqlclient-dev
Note: This installs the package for the MySQL server, as well as the packages for the client and for the database common files. During the installation, you are asked to supply a password for the root user for your MySQL installation.
The MySQL server is started automatically after installation. You can check the status of the MySQLserver with the following command:
sudo service mysql status
Stop the MySQL server with the following command:
sudo service mysql stop
To restart the MySQL server, use the following command:
sudo service mysql start
MySQL creates a default user called root. You can change the password to any password of your choice by logging in to MySQL console using socket authentication:
sudo mysql -u root
Then run the command below to change the password
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'your-preferred-password';

That's all.
I hope this helps
You can install mysql by
sudo apt install default-mysql-server

sudo service mysql status

Most likely you are running on ubuntu. It is important to run apt-get update first.

how to start mysql2 server?

I am trying to get some open source code running on my local machine. It uses mysql2, and I have not used this database before. I had some errors I was able to fix by running:
sudo apt-get install libmysql-ruby libmysqlclient-dev
I start up the rails server but when I go to http://localhost:3000/, I get the following error:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Do I need to start the MySQL server? How would I do that?
If you have your gem installed, start mysql before you run $ rails server
$ mysql.server start
To install MySql database:
sudo apt-get install mysql-server
To start MySql server:
/etc/init.d/mysql start
To stop MySql server:
/etc/init.d/mysql stop
To restart MySql server:
/etc/init.d/mysql restart
To check the status of MySql server:
/etc/init.d/mysql status
There is no mysql2 server. mysql2 is the name of a MySQL client gem (Ruby library). All you need is to install and start MySQL server.
It seems your server is Debian or Ubuntu. Execute apt-get install mysql-server to install MySQL. Your MySQL server will automatically start (by Upstart on Ubuntu or sysinit on Debian).
Just type command on terminal
/opt/lampp/lampp start if you have lamp server.Please let me know is it working for you,either I'll do other thing.
