[CentOS 8] 초기 세팅 | Services 확인

CentOS 8 설치 후 기본적으로 설치되는 서비스를 확인하는 방법과 불필요한 서비스를 중지하는 방법에 대해 알아보자.

 

1. 초기 세팅 | 서비스 확인

# 현재 활성화(Active)된 서비스 리스트 확인
[root@magicpipe ~]# systemctl -t service

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

64 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

2. 초기 세팅 | 서비스 실행/중지, 자동실행 등록/해제

# 특정 서비스 실행 (test 라는 서비스로 예시를 보이니, 실제 상황에서는 test 대신 실행하고자 하는 서비스를 입력한다)
[root@magicpipe ~]# systemctl start test

# 특정 서비스 중지
[root@magicpipe ~]# systemctl start test

# 특정 서비스 자동 실행 (서버 시작시 서비스 자동 실행)
[root@magicpipe ~]# systemctl enable test

# 특정 서비스 해제 (서버 시작시 서비스 자동 실행 해제)
[root@magicpipe ~]# systemctl disable test
