systemctl status mariadb.service
mysql -u root -p

grep "password" /var/log/mariadb/mariadb.log

ALTER USER 'root'@'localhost' IDENTIFIED BY '${your passwd}';
flush privileges;

2. Install develop environment for Tars
yum install -y npm
npm i -g pm2

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
source ~/.bashrc

nvm install v8.11.3
