jenkins yum 安裝

文章出處

jenkins 用過yum的方式安裝：服務的啟動和關閉等管理會很方便，版本升級也會變的很容易。
參考官方的說明：https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Red+Hat+distributions

jenkins安裝

#將jenkins的穩定版加入到yum 庫中
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
#安裝jenkins
sudo yum install jenkins

#jenkins 需要jdk1.8，如果低于1.8，啟動jenkins會報錯。
#安裝jdk1.8
yum remove java
rpm -ivh jdk-8u144-linux-x64.rpm

啟動或停止jenkins

sudo service jenkins start/stop/restart
sudo chkconfig jenkins on

修改jenkins默認的端口和啟動用戶

sudo vi /etc/sysconfig/jenkins

## 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="hadoop"


## Type:        integer(0:65535)
## Default:     8080
## ServiceRestart: jenkins
#
# Port Jenkins is listening on.
# Set to -1 to disable
#
JENKINS_PORT="8099"

修改jenkins默認的java的啟動參數：
sudo vi /etc/sysconfig/jenkins

#支持設置郵件發送starttls和信任列表
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Dmail.smtp.starttls.enable=true -Dmail.smtp.auth=true -Dmail.smtp.ssl.trust=mail.service.mtime.com"

如果修改默認啟動用戶，需要修改如下幾個目錄的權限

sudo rm -rf  /var/cache/jenkins/*
sudo rm -rf  /var/lib/jenkins/*

sudo chown -R hadoop:hadoop /var/log/jenkins
sudo chown -R hadoop:hadoop  /var/cache/jenkins/
sudo chown -R hadoop:hadoop /var/lib/jenkins

原有的jenkins配置拷貝到jenkins默認的目錄下
cp -R .jenkins/* /var/lib/jenkins/

啟動jenkins

sudo service jenkins start
sudo service jenkins status

歷史任務配置遷移后的異常：

jenkin --> 系統配置 --> 節點管理：
Host Key Verification Strategy 選擇：non verifying verification Strategay.

重啟之后就沒了。
