CentOS7 에서 MariaDB 10.0 설치 하기.

1. yum repository 에 mariadb 저장소 추가

[root@binrang-db yum.repos.d]# pwd
/etc/yum.repos.d
[root@binrang-db yum.repos.d]# vi MariaDB.repo
# MariaDB 10.0 CentOS repository list - created 2016-11-03 04:33 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]

baseurl = http://yum.mariadb.org/10.0/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

2. yum을 이용하여 아래와 같이 설치한다.

[root@binrang-db ~]# yum install MariaDB-server MariaDB-client

[root@binrang-db ~]# 

3. 환경설정 파일을 Copy 한다

[root@binrang-db ~]# cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
[root@binrang-db ~]# 

4. 언어설정 부분을 my.cnf에 추가한다.

[root@binrang-db ~]# 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
......

5. mariadb 를 실행한다.

[root@binrang-db ~]# service mysql start
Starting MySQL. SUCCESS! 
[root@binrang-db ~]# 

6. mariadb 를 서비스에 등록한다.

[root@binrang-db ~]# chkconfig mysql on
[root@binrang-db ~]# 
[root@binrang-db ~]# chkconfig --list

[root@binrang-db ~]# 

7. mariadb security 설정을 한다.

[root@binrang-db ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): 
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
You already have a root password set, so you can safely answer 'n'.
Change the root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] y
 ... Success!
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y
 ... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
 ... Success!
Cleaning up...
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
[root@binrang-db ~]# 


8. mariadb 재시작을 하자.

[root@binrang-db ~]# service mysql restart
Shutting down MySQL... SUCCESS! 
Starting MySQL. SUCCESS! 
[root@binrang-db ~]# 

9. 계정 생성 및 권한 을 부여 해 보자.

[root@binrang-db ~]# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 6

헐.. 에러다.. 이유는 기존에 5. 대 버전 설치 때 남겨진 찌거기가 남은 것이다.
제거 후 명령을 다시 입력하면 된다. 다시 해보자.

DB 생성은 5. 대 버전 것 참고하시길....
