安装步骤
导入秘钥
sudo wget -O /etc/yum.repos.d/jenkins.repo \
https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key更新yum源
sudo yum upgrade安装JDK（已安装可忽略）
sudo yum -y install fontconfig java-17-openjdk-devel
# 也可以选择安装JDK21
# sudo yum -y install fontconfig java-21-openjdk-devel安装Jenkins-2.426.2
sudo yum install -y jenkins-2.426.2重新加载 systemd 守护进程配置文件
sudo systemctl daemon-reload 启动 Jenkins
Jenkins 服务在启动时启动
sudo systemctl enable jenkins启动 Jenkins 服务
sudo systemctl start jenkins检查 Jenkins 服务的状态
sudo systemctl status jenkins如果一切都已正确设置，您应该会看到如下输出

如果安装了防火墙，则必须将 Jenkins 添加为例外。 您必须在下面的脚本中更改为要使用的端口
YOURPORT=8080 PERM="--permanent" SERV="$PERM --service=jenkins" firewall-cmd $PERM --new-service=jenkins firewall-cmd $SERV --set-short="Jenkins ports" firewall-cmd $SERV --set-description="Jenkins port exceptions" firewall-cmd $SERV --add-port=$YOURPORT/tcp firewall-cmd $PERM --add-service=jenkins firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload
使用
首次访问新的 Jenkins 实例时，系统会要求您使用 自动生成的密码
1. 浏览到（或您为其配置的任何端口） Jenkins）并等待 Unlock Jenkins 页面出现
http://localhost:8080
2. 从 Jenkins 控制台日志输出中，复制自动生成的 字母数字密码（在 2 组星号之间）
也可以执行命令查看密码
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
