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

the result of the command journalctl -xeu mysql.servicePlease help I am running Ubuntu 22.04
I had MySQL running perfectly before I installed MariaDB for a project and after I uninstalled MariaDB and installed MySQL but the server won't start.
The first Error I got when I type mysql in the terminal
"ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)" in 5 steps How can I fix this MySQL error on Ubuntu 22.04?
I tried to fix this by deleting the mariaDB files I found in the mysqld directory and editing the file mysqld.sock with the following informations
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[mysqld]
socket=/var/run/mysqld/mysqld.sock
[client]
socket=/var/run/mysqld/mysqld.sock
How do I completely uninstall and restore the MySQL server.
I tried to fix this by deleting the mariaDB files I found in the mysqld directory and editing the file mysqld.sock with the following informations

!includedir /etc/mysql/mysql.conf.d/
[mysqld]
socket=/var/run/mysqld/mysqld.sock
[client]
socket=/var/run/mysqld/mysqld.sock
This didn't work and I tried to uninstall and install mysql with the following command.
sudo apt remove --purge mysql-server mysql-client
sudo apt autoremove
sudo apt autoclean
sudo apt install mysql-server
now I got the message during installation.
MySQL has been frozen to prevent damage to your system. Please see /etc/mysql/FROZEN for help.
Then I ran this set of commands:
service mysql start
systemctl unmask mysql.service
service mysql start
journalctl -xeu mysql.service
sudo less /var/log/mysql/error.log
I tried to check the error log but there is no error log file
How do I completely uninstall and restore the MySQL server.
I have been able to solve the problem using these two lines of command
sudo apt remove --purge mysql-\*
sudo apt install mysql-server mysql-client
After this, I continued with the MySQL setup and it was a good as new

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 have what seems to be a common error, but all of the solutions I've found online aren't working for me.
I've been following a tutorial to display a MySQL table to a website in realtime (found here), and one of the first steps was to edit the MYSQL config file at /etc/mysql/my.cnf
[mysqld]
server-id = 1
log_bin = /var/log/mysql/mysql-bin.log #Or c:/logs/mysql-bin.log
expire_logs_days = 10
max_binlog_size = 100M
binlog-format = row
However, when I inserted this into the config file and restarted the MYSQL server as instructed, the server wouldn't start, throwing me the error:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
In hindsight, I should have just taken out the faulty lines of code from my config file, but I instead uninstalled MySQL and MariaDB thinking it was an error on the side of MySQL and reinstalled them. I'll include the lines of code I ran to do this below to ensure I didn't miss anything.
sudo apt remove --purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*
sudo apt install mysql-server
I then tried restarting the MySQL server with the following:
service mysql restart
/etc/init.d/mysqld restart
sudo systemctl start mysql
AFter this didn't work, I tried deleting all the contents of /var/lib/mysql and running the following line as instructed in another solution to this issue, which also didn't work.
mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
Even after reinstalling, it appears I am missing the /etc/mysql folder and the my.cnf file. I tried the line below to create it, but it doesn't work:
sudo dpkg-reconfigure mysql-server-5.7
Have I missed a step? Help is definitely appreciated.
