Amazon linux AMI and Percona server 5.6 don't appear to be compatible right out of the box. MySQL won't start after successful install.
In Perconas docs it does say that it is supported.
Steps to get to the below:
yum install http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
yum install Percona-Server-server-56
Which installs the client + shared 56 libraries as well.
Some more accurate logs.
[root#* ec2-user]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root#* ec2-user]# service mysql restart
ERROR! MySQL (Percona Server) PID file could not be found!
Starting MySQL (Percona Server).......... ERROR! The server quit without updating PID file (/var/lib/mysql/ip-172-30-0-92.pid).
On the most recent Amazon Linux AMI, I was able to start the server after running these commands:
yum install 'perl(Data::Dumper)'
yum reinstall Percona-Server-server-56
If the perl-Data-Dumper package is not installed, mysql_install_db fails to run and perform the initial setup.
The Percona-Server-server-56 package should declare a dependency on perl-Data-Dumper, but you can work around that error (and avoid the reinstall) by installing it first.

I have been successfully installing and using MySQL V5.7 in Google Colab (with Ubuntu 18.04) for quite some time. However trying to install MySQL V8 has repeated failed. I have used the following sequence of commands ..
!apt update
!apt upgrade
#!wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.11-1_all.deb
!wget https://dev.mysql.com/get/mysql-apt-config_0.8.22-1_all.deb
!dpkg -i mysql-apt-config_0.8.*
!sudo apt update
!sudo apt install mysql-server
During the install, I provide the root password and have used both the strong password option as well as the legacy authentication. Everything goes fine upto this point and even the following command
!mysqld --version
returns the correct version
/usr/sbin/mysqld Ver 8.0.28 for Linux on x86_64 (MySQL Community Server - GPL)
After this things go wrong! The MySQL service should have started but it hasn't
!mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
and when I try to start it, it is not recognised ( neither mysql nor mysqld)
!sudo service mysqld start
mysqld: unrecognized service
in fact, even this fails
!systemctl status mysql
System has not been booted with systemd as init system (PID 1). Can't operate.
What am I doing wrong? or what else should I do? or is it that for some reason, Google Colab with Ubuntu 18.04 does not support MySQL V8
No action required ... just this will do
!apt update > null
!apt -y install mysql-server -V
!/etc/init.d/mysql restart
then check
!mysql --version
mysql Ver 8.0.31-0ubuntu0.20.04.2 for Linux on x86_64 ((Ubuntu))
earlier this used to show Ver 5.7!
Now, with this we can now use CTE, recursion and Windows functions of v8
Check with sudo service mysql start or sudo start mysql once.
Another thing is that google colab instance might not use the system init system at all. That's why it's resulting in System has not been booted with systemd as init system. Check with the sys-v init system once. Its commands look like service service_name start. The same thing happens when trying to start services in WSL.
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.)

==> Caveats
We've installed your MySQL database without a root password. To secure
it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start

How can i completely remove this? Thank you for any help!
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.
I have a dedicated server with CentOS 7 command line OS, and then I remove MariaDB from it and download MySQL RPM packages(Red Hat Enterprise Linux 7 / Oracle Linux 7 (x86, 64-bit), RPM Bundle 5.7.1 557.1M) and then run rpm -ivh --replacefiles mysql-*.rpm for install that.
after install when I try to check mysql -version I face with this error
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
when I check the mysql datadir path in /var/lib/mysql/, this path haven't any files !!
please help me how I can install and then run MySQL server from rpm packages(offline mode) and then use it in CentOS 7. and How I can fix this problem.
thanks for helps.

I am having troubles starting MySQL Community Server. I am using Ubuntu 13.04. I have downloaded MySQL Community Server 5.6 the Debian package. I don't have any previous MySQL Versions installed.
I installed the package using this command dpkg -i mysql-5.6.14-debian6.0-i686.deb and it was successful.
I found the installation files in /opt/mysql. I opened /opt/mysql/server-5.6/supported-files and then typed: ./mysql.server start.
I got the following error:
The server quit without updating PID file (/opt/mysql/server-5.6/data/ubuntu.pid)
How can I solve that problem?
Thank You.
