5. Jenkins 설정

Jenkins는 기본 포트 8080으로 설정되어 있어 Tomcat과 충돌하기 때문에 9090으로 변경한다.

• 편집

[root@localhost ~]# vi /etc/sysconfig/jenkins

• 수정

JENKINS_PORT="9090"

6. 서비스 시작 및 종료

• 시작

[root@localhost ~]# service jenkins start
Starting jenkins (via systemctl):                          [  OK  ]
[root@localhost ~]#

• 종료

[root@localhost ~]# service jenkins stop
Stopping jenkins (via systemctl):                          [  OK  ]
[root@localhost ~]#

7. 방화벽 설정

설정한 포트 9090을 열어준다.

[root@localhost ~]# firewall-cmd --zone=public --permanent --add-port=9090/tcp
success
[root@localhost ~]# firewall-cmd --reload
success
[root@localhost ~]#

8. 웹 접속

• 접속 주소: http://서버주소:9090
• 초기 비밀번호: /var/lib/jenkins/secrets/initialAdminPassword에 있음

[root@localhost ~]# vi /var/lib/jenkins/secrets/initialAdminPassword
