mysqladmin으로 MYSQL의 환경변수를 확인하기(show variables)

 

 

 

 

 

 

 

MYSQL mysqladmin유틸리티로 현재 실행되어있는 MYSQL의 환경변수들을 확인할 수 있다.

 

 

 

 

  mysqladmin variables라는 명령어를 사용하면 현재 실행중인 MYSQL에 설정된 환경변수들을 확인할 수 있다.

 

 

 

 

  사용형식은 다음과 같다.

 

 

 

 

 

 

사용형식 : mysqladmin -u root -p variables

 

아래의 예는 현재 실행되어있는 MYSQL의 환경변수들을 확인하기 위하여 mysqladmin유틸리티를 사용한 것이다.

 

 

 

 

  아래의 예와 같이 MYSQL에 직접 접속하지 않은 리눅스 쉘상태에서 간편하게 MYSQL의 환경변수들을 점검해 볼 수 있다.

[root@sulinux bin]#

 

 

 

 

 

참고로 MYSQL의 환경변수들을 확인하는 방법에는 MYSQL에 접속한 후에 “show variables”라는 명령어를 사용할 수도 있다.

 

 

 

 

  결과는 위와 동일하다.

 

 

 

 

  즉 아래는 MYSQL root로 접속한 후에 “show variables”라는 명령어를 사용하여 MYSQL의 환경변수를 확인한 예이다.

 

 

 

 

 

 

[root@sulinux bin]#/usr/local/mysql/bin/mysql -u root -p mysql

Enter password: ********

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 20

Server version: 5.1.32 Source distribution

 

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

| character_set_connection        | euckr                                  |

| character_set_database          | euckr                                  |

이하생략

 

 

 

 

위의 결과가 앞의 예와 중복되므로 결과의 앞부분만을 나타낸 것이다.

 

 

 

 

  여기서 말하고자 하는것은 MYSQL의 환경변수를 확인하는 방법이 mysqladmin을 이용하는 방법외에도 MYSQL에 접속하여 “show variables”를 이용하는 방법도있다는 것이다.

 

 

 

 

 참고로 기억해두기 바란다.
