Ispmanager 5, CentOs 7
I just uninstall default Mysql with commands:
service mariadb stop
yum remove mariadb mariadb-server
Than upgraded it with mariadb 10.3:
cat > /etc/yum.repos.d/MariaDB.repo <<EOF
# MariaDB.repo
# MariaDB 10.3 CentOS repository list
# 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
EOF
yum -y install MariaDB-server MariaDB-client
mkdir -p /var/run/mysqld
chown -R mysql:mysql /var/run/mysqld
systemctl enable mariadb
service mariadb start
After this - all things working fine except this:
The server settings - is empty. Edit button is disabled.
PS: /etc/my.cnf is on its place, mysql --help shows than it uses /etc/my.cnf and ~/my.cnf
I edited the parameter to new path
path mysqld usr/sbin/mysqld
in /usr/local/mgr5/etc/ispmgr.conf.d/mysql.conf
Because new version of mariadb uses another path of the mysqld.
After this all things works like a charm )))

I configured 3 drives on my machine: 1 for data files, 1 for transaction logs files, and 1 for temporary files.
I would like to initialize MariaDB at its first run straight after yum installation. Here are my steps:
created /etc/my.cnf with the following parameters
[mysqld]
aria-log-dir-path=/tempdb/mysql/
datadir=/data/mysql/
tmpdir=/tempdb/mysql/
innodb_data_home_dir=/data/mysql/
innodb_log_group_home_dir=/tlogs/mysql/
innodb_undo_directory=/tlogs/mysql/
aria-log-dir-path=/tempdb/mysql/
install MariaDB
sudo yum -y update
sudo tee /etc/yum.repos.d/MariaDB.repo<<EOF
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF
sudo yum makecache fast
sudo yum -y install MariaDB-server MariaDB-client
sudo systemctl start mariadb
I get the following exception
Can't start server : Bind on unix socket: No such file or directory
Can anyone shed some light on what I'm doing wrong? is this the right procedure to achieve my goal?
Thx

I installed MariaDB on CentOS 7 but I had some problems with some configuration, now it is completely misconfigured.
Thus, I wanted to remove the MariaDB with “yum remove mariadb mariadb-server”, after that I reinstalled it with “yum install mariadb mariadb-server”.
Unfortunately, the configuration remains. It seems as if yum remove don’t delete all MariaDB Config-Files.
How can I remove MariaDB completely from CentOS 7?
These steps are working on CentOS 6.5 so they should work on CentOS 7 too:
(EDIT - exactly the same steps work for MariaDB 10.3 on CentOS 8)
yum remove mariadb mariadb-server
rm -rf /var/lib/mysql If your datadir in /etc/my.cnf points to a different directory, remove that directory instead of /var/lib/mysql
rm /etc/my.cnf the file might have already been deleted at step 1
Optional step: rm ~/.my.cnf
yum install mariadb mariadb-server
[EDIT] - Update for MariaDB 10.1 on CentOS 7
The steps above worked for CentOS 6.5 and MariaDB 10.
I've just installed MariaDB 10.1 on CentOS 7 and some of the steps are slightly different.
Step 1 would become:
yum remove MariaDB-server MariaDB-client
Step 5 would become:
yum install MariaDB-server MariaDB-client
The other steps remain the same.
To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:
rpm -qa | grep mariadb
then remove the mariadb packages using (changing to your versions):
rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"
Delete left over files and folders (which also removes any databases):
rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql
Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.
There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL
systemd
sudo systemctl stop mysqld.service && sudo yum remove -y mariadb mariadb-server && sudo rm -rf /var/lib/mysql /etc/my.cnf
sysvinit
sudo service mysql stop && sudo apt-get remove mariadb mariadb-server && sudo rm -rf /var/lib/mysql /etc/my.cnf
I have been downloaded the DEB package of mysql 5.5.23.
Install MySQL by the command as follows:
sudo dpkg -i mysql-5.5.23-debian6.0-x86_64.deb
The result said that installed successfully.
But when I type the command:
sudo service mysql start
Or
mysql
It shows me that "mysql: unrecognized service" or "mysql: command not found".
Besides, I can't find MySQL files in "/usr/include" or "/usr/bin"
Please help me. Thx.
Because MySQL 5.5.x is not packaged, in repositories only exist 5.1.x
This worked for me:
http://www.rebojo.com/debian-installing-mysql/
Why not a simple command :
sudo apt-get install mysql-server
MySQL Download URL
https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
Open the terminal and follow along:
Uninstall any existing version of MySQL
sudo rm /var/lib/mysql/ -R
Delete the MySQL profile
sudo rm /etc/mysql/ -R
Automatically uninstall mysql
sudo apt-get autoremove mysql* --purge
sudo apt-get remove apparmor
Download version 5.5.51 from MySQL site
wget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
Add mysql user group
sudo groupadd mysql
Add mysql (not the current user) to mysql user group
sudo useradd -g mysql mysql
Extract it
sudo tar -xvf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
Move it to /usr/local
sudo mv mysql-5.5.56-linux-glibc2.5-x86_64 /usr/local/
Create mysql folder in /usr/local by moving the untarred folder
cd /usr/local
sudo mv mysql-5.5.49-linux2.6-x86_64 mysql
set MySql directory owner and user group
cd mysql
sudo chown -R mysql:mysql *
Install the required lib package (works with 5.6 as well)
sudo apt-get install libaio1
Execute mysql installation script
sudo scripts/mysql_install_db --user=mysql
Set mysql directory owner from outside the mysql directory
sudo chown -R root .
Set data directory owner from inside mysql directory
sudo chown -R mysql data
Copy the mysql configuration file
sudo cp support-files/my-medium.cnf /etc/my.cnf
Start mysql
sudo bin/mysqld_safe --user=mysql &
sudo cp support-files/mysql.server /etc/init.d/mysql.server
Set root user password
sudo bin/mysqladmin -u root password '[your new password]'
Add mysql path to the system
sudo ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql
Reboot!
Start mysql server
sudo /etc/init.d/mysql.server start
Stop mysql server
sudo /etc/init.d/mysql.server stop
Check status of mysql
sudo /etc/init.d/mysql.server status
Enable myql on startup
sudo update-rc.d -f mysql.server defaults
*Disable mysql on startup (Optional)
`sudo update-rc.d -f mysql.server remove`
REBOOT!
Now login using below command, start mysql server if it's not running already
mysql -u root -p
