[root@localhost ~]# 



환경설정 파일을 복사 해 온다. (자신의 서버에 맞는 걸로...)

[root@localhost ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
cp: overwrite `/etc/my.cnf'? y
[root@localhost ~]# 

언어 설정 부분을 아래와 같이 2라인을 추가한다.

[root@localhost ~]# vi /etc/my.cnf
# Example MariaDB config file for medium systems.
#
.....
[mysqld]
# 여기 언어 설정 부분을 추가한다.
character-set-server=utf8
collation-server=utf8_general_ci
port            = 3306
socket          = /var/lib/mysql/mysql.sock
skip-external-locking
......

mariadb 서버를 시작한다.

[root@localhost ~]# service mariadb start
Redirecting to /bin/systemctl start  mariadb.service
[root@localhost ~]# 

mariadb 의 root 패스워드를 변경한다.

[root@localhost ~]# mysqladmin password
New password: 
Confirm new password: 
[root@localhost ~]# 

테스트를 위해 새로운 DB와 사용자를 추가하고 원격 또는 로컬에서도 접속이 가능하도록 해보자.

[root@localhost ~]# mysql -uroot -p 
Enter password:

이제 서비스에 등록해보자.

[root@localhost ~]# systemctl enable mariadb.service
ln -s '/usr/lib/systemd/system/mariadb.service' '/etc/systemd/system/multi-user.target.wants/mariadb.service'
[root@localhost ~]# 

서비스를 재시작해보자.

[root@localhost ~]# service mariadb restart
Redirecting to /bin/systemctl restart  mariadb.service
[root@localhost ~]# 

이제 만들어 놓은 DB에 접속을 해 보자.

[root@localhost ~]# mysql -ubinrang -p test_db
