Install Jenkins CI on CentOS 6.x

젠킨스 Flow

환경

OS : CentOS release 6.8 (Final)

JDK 기설치 : java version "1.7.0_79"

yum을 이용한 설치

wget, lrzsz, JDK 설치.

# yum -y install wget

# yum -y install lrzsz

# java -version

java version "1.7.0_79"

Java(TM) SE Runtime Environment (build 1.7.0_79-b15)

Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

Jenkins 설치.

# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo

# rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key

# yum -y install jenkins

# service jenkins start

Starting Jenkins bash: /usr/bin/java: No such file or directory

[FAILED]

에러발생

해결방법 :

Jenkins needs java to start and in your case in /usr/bin/ directory java is not available

If you go to /etc/init.d/ and open jenkins file you will find:

# vi /etc/init.d/Jenkins

(현재)

candidates="

/etc/alternatives/java

/usr/lib/jvm/java-1.6.0/bin/java

/usr/lib/jvm/jre-1.6.0/bin/java

/usr/lib/jvm/java-1.7.0/bin/java

/usr/lib/jvm/jre-1.7.0/bin/java

/usr/lib/jvm/java-1.8.0/bin/java

/usr/lib/jvm/jre-1.8.0/bin/java

/usr/bin/java

"

These are the paths where jenkins looks for java, and in your case java was not present in any of the above paths.

So look for the path where you are having java and add that path in the above jenkins file.

Since you are having java in /opt/jdk/bin, then add this in jenkins file:

# which java

/opt/java/jdk7/latest/bin/java

# vi /etc/init.d/Jenkins

(아래와 같이 수정)

candidates="

/opt/java/jdk7/latest/bin/java <----Add here (이 부분을 추가 해준다.)

/etc/alternatives/java

/usr/lib/jvm/java-1.6.0/bin/java

/usr/lib/jvm/jre-1.6.0/bin/java

/usr/lib/jvm/java-1.7.0/bin/java

/usr/lib/jvm/jre-1.7.0/bin/java

/usr/lib/jvm/java-1.8.0/bin/java

/usr/lib/jvm/jre-1.8.0/bin/java

/usr/bin/java

다시 실행

# service jenkins start

웹브라우저로 http://서버ip:8080 접속

페이지 가 나오지 않는다면 다음과 같이 port 설정

# vi /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

를 추가하여 Jenkins 기본 포트인 8080으로 접속이 가능하게 한다.

# service iptables restart

iptables: 방화벽 규칙을 지웁니다: [ OK ]

iptables: 체인을 ACCEPT 규칙으로 설정 중: filter [ OK ]

iptables: 모듈을 언로드하는 중: [ OK ]

iptables: 방화벽 규칙 적용 중: [ OK ]

웹브라우저로 http://서버ip:8080 접속.
