Jenkins安装
1.检测是否有java环境
java -version
2.启用Jenkins仓库
wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo
rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key
3.安装Jenkins
yum install jenkins
4.启动Jenkins服务,有需要可以执行第二条命令将Jenkins设置成开机自启动
service jenkins start
chkconfig jenkins on
5.访问服务器地址的8080 端口,初始化密码在以下文件夹
cat /var/jenkins/secrects/initialAdminPassword
几个遇到的问题
1.更新默认插件、安装新插件失败

1.修改插件中的配置
将http://ip:8080/jenkins/pluginManager/advanced替换成http://updates.jenkins.io/update-center.json,然后重启服务
2.进入Jenkins站点修改默认json配置
cd /var/lib/jenkins/updates/
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json
sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
3.查找证书所在路径并将这个路径添加到配置文件中
-Djavax.net.ssl.trustStore=/etc/pki/ca-trust/extracted/java/cacerts
find / -type f -name cacerts
vi /etc/sysconfig/jenkins
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djavax.net.ssl.trustStore=/etc/pki/ca-trust/extracted/java/cacerts"
2.链接Git失败
Failed to connect to repository : Command "git ls-remote -h -- https://gitee.com/***/***.git HEAD" returned status code 128:
stdout:
stderr: remote: [31mIncorrect username or password ( access token )[0m
fatal: Authentication failed for 'https://gitee.com/***/***.git/'
在配置中设置默认用户名密码 Jenkins默认生成的用户名密码是Jenkins/Jenkins
docker安装
1.添加软件包
yum install -y yum-utils device-mapper-persistent-data lvm2
2.添加yum源
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
3.安装最新版本
yum install docker-ce -y
4.尝试启动docker
systemctl start docker
systemctl enable docker
5.如果出现以下错误,说明当前内核不支持selinux,编辑docker配置文件关闭selinux再重新启动就行
Error starting daemon: SELinux is not supported with the overlay2 graph driver on this kernel. Either boot into a newer kernel or disable selinux in docker (--selinux-enabled=false)
vi /etc/sysconfig/docker
将这个文件中的OPTIONS='--selinux-enable '改成--selinux-enabled=false即可
