***************************************************************
This is a normal Router with a SW module inside (NM-16ESW)
It has been preconfigured with hard coded speed and duplex

To create vlans use the command "vlan database" from exec mode
After creating all desired vlans use "exit" to apply the config

To view existing vlans use the command "show vlan-switch brief"

Warning: You are using an old IOS image for this router.
Please update the IOS to enable the "macro" command!

mariadb 외부 접속 방법 mysql 외부 접속 방법

1. mysql 접속 후 mysql database 선택 

mysql> use mysql;

2. user 테이블 살펴보기 

mysql> select host, user, password from user;

root 의 host 값들은 localhost, 127.0.0.1 등으로 기본 등록되어 있지만, 외부접속을 나타내는 값이 없다. 특정 아이피로 지정할 수도 있지만 여기선 % 기호로 어디서든 접속 가능하게 만든다. 

3. 권한 설정 

mysql> grant all privileges on *.* to 'root'@'%' identified by 'root의 패스워드';

Query OK, 0 rows affected (0.03 sec)

4. 등록확인하기

mysql> select host, user, password from user;

root 계정의 host 필드에 % 가 등록되었는지 확인한다. 

5. refrash

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

위 단계는 my.cnf 파일 수정후 서버를 재시작할 것이기 때문에 굳이 안해도 된다. 

6. my.cnf 에서 외부접속 관련사항 변경하기 

user@home:~$ sudo vim /etc/mysql/my.cnf 

파일 내용중 

bind-address = 127.0.0.1 

부분 주석처리후 저장하기 

7. mysql 재시작 

user@home:~$ sudo /etc/init.d/mysql restart 

8. 완료. 

이제 외부 클라이언트 프로그램에서 접속이 가능하다 ^^
