centos6.9安装Jenkins服务

1.安装javajdk，默认centos6.9只能下载到java8，安装成功后Jenkins会有一堆插件用不了，使用这里手动安装java17，在官网找对应安装包

https://www.oracle.com/java/technologies/downloads/#java17

这里下载了jdk-17_linux-x64_bin.rpm格式

 

rpm -ivh 文件名
java -version 查看下版本，有输出就安装成功了

设置JAVA_HOME：为了方便使用Java 17，您可以设置JAVA_HOME环境变量。编辑/etc/profile文件，并在文件末尾添加以下行：

export JAVA_HOME=/usr/java/jdk-17
export PATH=$JAVA_HOME/bin:$PATH

保存文件并退出。然后运行以下命令以使更改生效：

source /etc/profile

至此java环境安装成功

 

安装Jenkins

2. 添加Jenkins仓库的GPG密钥：
```
sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key
```

3. 添加Jenkins仓库到yum源列表：
```
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
```

4. 导入Jenkins仓库的GPG密钥：
```
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
```

6. 安装Jenkins：
```
sudo yum install jenkins

注意这里默认会装上最新的，根据你本地的环境可能会下不了，我安装的时候就报错了

解决方法：到Jenkins仓库官网看下https://pkg.jenkins.io/redhat-stable/ 有什么版本可以用

 

 sudo yum install jenkins-2.361.1

指定这个版本我就安装成功了

```

7. 启动Jenkins服务：
```
sudo service jenkins start
```

8. 配置Jenkins服务开机自启动：
```
sudo chkconfig jenkins on
```

9. 打开防火墙端口，允许Jenkins流量通过：
```
sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent
sudo firewall-cmd --reload
```

10. 完成安装后，通过以下URL访问Jenkins Web界面：
```
http://your_server_ip:8080
```

11. 在首次访问时，您将需要提供Jenkins管理员密码。您可以通过以下命令找到该密码：
```
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
```

复制密码并粘贴到Jenkins Web界面中进行验证。
