1、安装jenkins
1.1 安装jdk
要求：11及以上版本
yum install yum install java-11-openjdk1.2 安装jenkins
导入镜像
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
出现以下错误
执行以下命令
sudo yum install -y ca-certificates
导入key
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key安装jenkins
yum install jenkins2 配置jenkins
2.1 配置服务端口
vim /usr/lib/systemd/system/jenkins.service修改Environment="JENKINS_PORT=9080"
2.2 配置 jenkins 用户组
Jenkins 安装好后，会自动创建一个 jenkins 用户。jenkins 在构建工程时，默认的权限是不够写入文件的。这时就需要把它的权限提升为root。
将 jenkins 账号加入到 root 组中。
gpasswd -a jenkins root修改vim /usr/lib/systemd/system/jenkins.service文件，修改如下配置。
重启服务
systemctl daemon-reload
systemctl restart jenkins2.3 配置jenkins镜像加速
配置jenkins镜像加速
vim /var/lib/jenkins hudson.model.UpdateCenter.xml原配置
<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<url>https://updates.jenkins.io/update-center.json</url>
</site>
</sites>修改为以下配置
<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url>
</site>
</sites>也可在登录Jenkins后在插件的高级设置里配置镜像加速，如下图所示
3 初始化配置jenkins
访问web页面（http://IP:端口）
3.1 获取初始密码登录
cat /var/lib/jenkins/secrets/initialAdminPassword输入初始密码
3.2 安装插件，推荐的即可
3.3 创建用户 并登录
3.4 安装插件
1、安装maven插件
3、安装Pipeline Utility Steps
4、安装Nodejs
5、安装Blue Ocean
4 全局工具配置
4.1、maven 配置
4.2、nodejs 配置
4.2 maven配置修改
vim /var/lib/jenkins/tools/hudson.tasks.Maven_MavenInstallation/maven-3.9.4/conf/settings.xml5 创建多分支流水线
1、打开Blue Ocean
2、创建新的流水线
配置仓库和凭证信息
退出Blue Ocean，打开流水线项目
3、扫描多分支流水线
6、docker 镜像推送到Habour及部署到远程服务器
项目的Jenkinsfile

7、webhook触发自动化构建部署
环境：Gogs
1、创建钩子
2、配置推送地址
3、测试验证
4、推送失败问题
如果提示
Did not find any jobs with GenericTrigger configured!\nA token was supplied.\n
是因为创建多分支流水线后，jenkins没有重启，gogs推送过去jenkins说找不到token对应的job，重启下jenkins服务即可。这算jenkins的一个bug吧！
