CentOS 7 部署 jenkins

环境: CentOS 7.6

方式一(不推荐使用yum安装)

• 获取安装源

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

• 安装公钥

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

• 安装Jenkins

yum install jenkins

• 修改配置

vim /etc/sysconfig/jenkins

修改如下:

JENKINS_PORT="8080"  #Jenkins服务访问端口
JENKINS_USER="root"  #用户为root

• 修改目录权限

chown -R root:root /var/lib/jenkins
chown -R root:root /var/cache/jenkins
chown -R root:root /var/log/jenkins

• 启动Jenkins

service jenkins start
ps -ef | grep jenkins

错误信息:

Starting Jenkins bash: /usr/bin/java: No such file or directory      #未找到java文件

解决方法,创建java文件软连接:

ln -s /usr/local/java/jdk1.8.0_171/bin/java /usr/bin/java

• 重新启动Jenkins

service jenkins restart

• 访问Jenkins控制台
  浏览器输入http://ip:8080,提示输入密码,执行如下命令查看:

#查看初始密码
cat /var/lib/jenkins/secrets/initialAdminPassword

提示实例已离线,解决办法:

访问: http://ip:8080/pluginManager/advanced 

修改升级站点为:
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
或者
http://mirror.xmission.com/jenkins/updates/current/update-center.json

#镜像仓库仓库网站:
http://mirrors.jenkins-ci.org/status.html
#重启Jenkins
service jenkins restart

方式二(推荐使用docker安装)

• 拉取镜像

docker pull jenkins/jenkins

• 添加用户

useradd jenkins

• 挂载目录

mkdir -p /home/jenkins            #新增jenkins目录
vim /home/jenkins/log.properties  #编辑日志配置文件

添加如下配置:

handlers=java.util.logging.ConsoleHandler
jenkins.level=FINEST
java.util.logging.ConsoleHandler.level=FINEST

• 赋予权限

chmod -R 777 /home/jenkins                    #给目录赋权
chown -R jenkins:jenkins /home/jenkins        #赋予用户权限
chown -R 1000:1000 /home/jenkins
#查看权限是否设置成功
ls -nd /home/jenkins

如下显示证明赋权成功:

drwxrwxrwx 2 1000 1000 4096 Aug  8 10:40 /home/jenkins

• 启动容器

docker run -d --name jenkins \
-p 8080:8080 -p 50000:50000  \
--privileged=true \
--restart=always \
-v /etc/timezone:/etc/timezone \
-v /etc/localtime:/etc/localtime \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $(which docker):/usr/bin/docker \
-v /home/jenkins:/var/jenkins_home \
-v /usr/bin/mv:/usr/bin/mv \
-v /usr/java/jdk-11.0.4/bin/java:/usr/local/jdk/bin/java \
-v /usr/local/maven:/usr/local/maven \
-v /usr/java/jdk-11.0.4:/usr/local/jdk \
-v /usr/lib64/libltdl.so.7:/usr/lib/x86_64-linux-gnu/libltdl.so.7 \
-u 0 jenkins/jenkins \
--prefix=/jenkins

• 访问jenkins控制台
  http://ip:8080/jenkins,提示输入密码,因将jenkins容器挂载至 /home/jenkins,直接执行如下命令:

cat /home/jenkins/secrets/initialAdminPassword

若提示该实例似乎已离线,参考yum安装方式该问题处理办法即可.
