* 자동서비스

1> 개념

- 시스템을 재부팅하면 서버가 자동 서비스로 설정한 서비스를 딱 한 번 시작 해줌

- 자주 사용하는 서비스를 설정

- 별도로 해당 서비스를 작업시 본인이 서비스를 껏다가 다시 시작해야 함

2> 명령어

centOS 6(이하)	centOS 7
chkconfig service(daemon) on	systemctl enable service(daemon)
chkconfig service(daemon) off	systemctl disable service(daemon)
chkconfig --list service(daemon)	systemctl is-enabled service(daemon) systemctl list-dependencies --before service(daemon) systemctl list-dependencies --after service(daemon)
chkconfig --list	systemctl list-unit-files --type service(daemon)

<실습1>

nfs service와 autofs service 최종 실습

서버와 클라이언트를 스냅샷 돌리고 진행(총 2대)

nfs server

HDD(SCSI, 1GB) partition은 5개 설정, 용량은 자유롭게

nfs service 작업할 때

첫번째 호스트가 읽고 쓰기가 가능하며 nfs client의 root를 무시하지 않고 인정

두번째 네트워크 대역으로 읽고 쓰기가 가능하며 nfs client의 root를 무시

세번째 모든 네트워크가 읽기 전용으로 가능하며 nfs client의 root를 무시

auto mount

nfs service를 자동 서비스로 등록

nfs client

nfs server가 공유한 파일 시스템을 nfs service를 이용하여 설정한 뒤에 nfs server와 공유되는지 확인

nfs server가 공유한 파일 시스템을 autofs service를 이용하여 설정한 뒤에 nfs server와 공유되는지 확인

nfs server가 공유한 파일 시스템을 nfs service 또는 autofs service를 이용하여 설정한 뒤에 nfs server와

공유되는지 확인(이 때, autofs service로 설정을 했으면 반드시 재부팅하여 nfs server와 공유되는지 확인)
