3 서비스 시작

[root@jmnote ~]# service mysqld start
Initializing MySQL database:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h jmnote password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]

4 패스워드 변경

[root@jmnote ~]# /usr/bin/mysqladmin -u root password 'P@ssw0rd'

→ MySQL의 root계정^[1] 패스워드를 P@ssw0rd로 바꾸었다.

→ 이것은 최초 설치시만 된다. MySQL을 재설치시에도 안된다...

→ 만약 패스워드를 모른다면 MySQL root 패스워드 분실 참고

5 로컬 접속 확인

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

→ 패스워드를 입력하면 잘 접속된다.
