Become root user and initialize mysqld:
#mysqld --defaults-file=/etc/my.cnf --initialize &

Get temporary password from log file:
#grep -i generate /mysql/db_name/logs/db_name.err

Start mysqld using user mysql:
$ mysqld --defaults-file=/etc/my.cnf &

mysql> alter user 'root'@'localhost' identified by '<your_code>';
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<your_code>';
mysql> select * from mysql.user \G
mysql> show databases;

Configure mysqld to start, stop using systemctl:

Shutdown mysqld:
$  mysqladmin -uroot -proot123# -S/mysql/db_name/data/<db_name>.sock shutdown

Configure systemd to start and stop mysqld:

Edit file - /usr/lib/systemd/system/mysqld.service and add following under Service
PIDFile=/mysql/db_name/data/db_name.pid
ExecStart=/usr/sbin/mysqld --defaults-file=/etc/my.cnf --daemonize --pid-file=/mysql/db_name/data/db_name.pid $MYSQLD_OPTS
Reload mysqld:
#systemctl reload-daemon
Start mysqld service using systemctl:
#systemctl start mysqld
If you get permission denied error, set SELINUX to permissive  - http://shrenikp.blogspot.com/2018/11/mysql-error-could-not-open-file.html
