Jenkins安装——Yum安装和Docker安装

Jenkins安装

Yum安装Jenkins

要在CentOS 7上安装Jenkins，您可以按照以下步骤进行操作：

1. 更新系统软件包：

sudo yum update

1. 安装Java Development Kit (JDK)。Jenkins需要Java来运行。您可以选择安装OpenJDK或Oracle JDK。以下是安装OpenJDK的示例命令：

sudo  yum install fontconfig java-11-openjdk

2. 导入Jenkins存储库的GPG密钥：

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key --no-check-certificate

3. 安装Jenkins：

sudo yum install jenkins

4. 启动Jenkins服务：

sudo systemctl start jenkins && sudo systemctl daemon-reload

5. 配置Jenkins开机自启动：

sudo systemctl enable jenkins

6. 打开防火墙端口以允许访问Jenkins的Web界面：

sudo firewall-cmd --permanent --zone=public --add-port=8080/tcp
sudo firewall-cmd --reload

现在，您可以通过在Web浏览器中输入http://your_server_ip:8080来访问Jenkins的Web界面，并按照屏幕上的指示完成Jenkins的安装设置。

请注意，安装Jenkins可能需要一些时间，具体取决于您的互联网连接速度和系统配置。
