Linux 에서 swapfile 만들고 적용하기

* 4GB 크기의 스왑 파일용 자리 만들기
fallocate -l 4G /swapfile.img

* 스왑 파일 퍼미션 지정
chmod 600 /swapfile.img

* 스왑 파일 만들고 켜기
mkswap /swapfile.img
swapon /swapfile.img

* /etc/fstab의 swap 파티션 자리에 이 내용 추가하기
/swapfile none swap defaults 0 0

최소설치로 한 경우만 해당
GUI서버로 설치한경우에는 이미 설치 되 있음.

dnf install libnsl

CentOS에서 설치해 봄.

firewall-cmd --add-masquerade --permanent   (fedora는 이것도 해줘야 한다)

firewall-cmd --add-forward-port=port=80:proto=tcp:toport=8080 --permanent

firewall-cmd --permanent --direct --add-rule ipv4 nat OUTPUT 0 -p tcp -o lo --dport 80 -j REDIRECT --to-port 8080

찻번째는는 외부에서 접속하는 클라이언트를 위한것
둘째는 localhost를 위한것

만약 1521포트를 oracle이라는 service명으로 만들려면
/usr/lib/firewalld/services
경로에서 만만한 smtp.xml을 oracle.xml로 복사한다.
예) cp smtp.xml oracle.xml
vi에디터로 oracle.xml을 열어서 포트를 25에서 1521로 
변경후 저장
firewall-cmd --permanent --add-port=1521/tcp
대신 
firewall-cmd --permanent --add-service=oracle
하면 포트대신 service명으로 개방할 수 있다.

/usr/lib/firewalld/services 이경로에 없는 것들은 
다 포트로 직접 개방해야 하지만 직접 service명.xml을
만들어 놓으면 service명으로 개방이 가능하다.
개인적으로 포트번호보다는 service명으로 개방하는 
것을 선호하기에....

service명으로 추가할 때
firewall-cmd --permanent --add-service=ftp

port로 직접 추가할때
firewall-cmd --permanent --add-port=1521/tcp

추가한 내용 적용은
firewall-cmd --reload
