解决方法:
1.更新站点
https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
2.下载插件Skip Certificate Check的安装文件
https://plugins.jenkins.io/skip-certificate-check/
3.在Jenkins离线安装插件
还是刚刚更换站点的那个页面,把刚刚下载下来的文件上传然后点击deploy即可
安装完成后重启Jenkins即可解决
二.jenkins启动失败: jenkins: failed to find a valid Java installation
解决办法
首先要确保java环境变量可以用
1.查看java环境变量的命令
which java
2.检查配置文件
vim /etc/init.d/jenkins
vim /etc/sysconfig/jenkins
检查配置文件中的JAVA环境变量是否都配置正确, 如果有问题就更改为正确的 , 然后执行如下命令使配置重新生效
systemctl daemon-reload
如果配置正确 , 也可以执行上面的命令 , 然后重启 , 如果还是启动失败 , 并且通过
journalctl -xe
命令看到报错
那么可以使用ln -s的方式建立软连接
3.建立软连接
ln -s /usr/local/jdk/jdk1.8/bin/java /usr/bin/java
4.重新载入配置
systemctl daemon-reload
5.重启Jenkins
systemctl start jenkins
