- 코드
- INS-41112
- 원인
- RAC 설치과정중에 두개의 Node간 ping이나 SSH등은 가능하지만 firewalld , iptables가 종료되지 않을때 발생
- 해결
- Step - 1
(차후 문제 발생을 예방하기 위해 firewalld 서비스도 종료시킨다)
# service iptables stop
Redirecting to
/bin/systemctl stop iptables.service
# chkconfig iptables off
Note: Forwarding
request to 'systemctl disable iptables.service'.
# systemctl stop firewalld
# systemctl disable firewalld
rm
'/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm
'/etc/systemd/system/basic.target.wants/firewalld.service'
- Step - 2
보안 관련 서비스를 종료시킨 이후에 검증과정을 위해 GRID_HOME의 소유권자 계정
으로 아래 Script를 실행시킨뒤 pass / fail을 확인한다
$ cd
/u01/media/grid/
$ ./runcluvfy.sh
comp nodecon -n rac1,rac2 -verbose
