mysqladmin으로 MYSQL의 현재 상황 자세히 살펴보기(extended-status)

 

 

 

 

 

 

  이번에는 MYSQL mysqladmin유틸리티를 이용하여 앞의 경우보다 자세한 MYSQL 실행정보들을 확인하는 방법을 알아보겠다.

 

 

 

 

 MYSQL의 자세한 실행정보를 확인하는 mysqladmin유틸리티의 사용형식은 다음과 같다.

 

 

 

 

 

 

사용형식 : mysqladmin -u root -p extended-status

 

 

 

 

 

mysqladmin유틸리티에 extended-status라는 명령어를 주어서 실행하면 아래 예에서 보는 바와같이 MYSQL의 자세한 실행상황 정보를 확인할 수 있다.

 

 

 

 

 

 

[root@RockyLinux mysql]# mysqladmin -u root -p extended-status
