jenkins安裝

jenkins是通用的持續集成工具，應用很是普遍。下面開始在服務器安裝jenkins，記錄安裝過程。

一、添加yum repos，而後安裝

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key

sudo yum install jenkins

二、若是未安裝java還需安裝java

三、啓動和中止

sudo service jenkins start
sudo service jenkins stop
sudo service jenkins restart

四、若是啓動報錯，一般是由於配置文件設置的jdk環境不對。修改配置文件  

vi /etc/rc.d/init.d/jenkins

找到以下類似地方：

# Search usable Java as /usr/bin/java might not point to minimal version required by Jenkins.
# see http://www.nabble.com/guinea-pigs-wanted-----Hudson-RPM-for-RedHat-Linux-td25673707.html
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/bin/java

能夠把本身本機java路徑加入進來。

 

五、若是提示權限問題，能夠修改默認USER或者修改文件owner，簡單起見咱們直接把默認用戶從jenkins換成root。

固然，安全起見，真實的線上環境不建議這麼操做。

修改配置文件  /etc/sysconfig/jenkins

修改下面的參數爲相應的用戶，好比JENKINS_USER="root"

## Type:        string
## Default:     "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"

 

六、修改相應文件或目錄的權限

/var/lib/jenkins/
/var/log/jenkins/
/var/cache/jenkins/
/usr/lib/jenkins/jenkins.war
/etc/sysconfig/jenkins

chown -R root:root /var/lib/jenkins/
chown -R root:root /var/log/jenkins/
chown -R root:root /var/cache/jenkins/
chown root:root /usr/lib/jenkins/jenkins.war
chown root:root /etc/sysconfig/jenkins

 

七、重啓jenkins：service jenkins restart

八、修改端口號:

vim /etc/sysconfig/jenkins

找到相似：

## Type:        integer(0:65535)
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8080"

直接將默認8080修改成本身指定的端口便可。

 

登錄時默認初始密碼地址：

/var/lib/jenkins/secrets/initialAdminPassword
