jenkins yum 安装

jenkins yum 安装

jenkins 用过yum的方式安装：服务的启动和关闭等管理会很方便，版本升级也会变的很容易。
参考官方的说明：https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Red+Hat+distributions

• jenkins安装

#将jenkins的稳定版加入到yum 库中
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
#安装jenkins
sudo yum install jenkins

#jenkins 需要jdk1.8，如果低于1.8，启动jenkins会报错。
#安装jdk1.8
yum remove java
rpm -ivh jdk-8u144-linux-x64.rpm

• 启动或停止jenkins

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

• 修改jenkins默认的端口和启动用户

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默认的java的启动参数：
  sudo vi /etc/sysconfig/jenkins

#支持设置邮件发送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"

• 如果修改默认启动用户，需要修改如下几个目录的权限

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配置拷贝到jenkins默认的目录下
  cp -R .jenkins/* /var/lib/jenkins/
• 启动jenkins

sudo service jenkins start
sudo service jenkins status

历史任务配置迁移后的异常：

jenkin --> 系统配置 --> 节点管理：
Host Key Verification Strategy 选择：non verifying verification Strategay.

重启之后就没了。
