官网下载安装包比较慢，推荐去清华源进行下载。

# 使用sed命令修改
[root@centos7 jenkins]#sed -i 's@https://updates.jenkins.io/update-center.json@https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json@i' /var/lib/jenkins/hudson.model.UpdateCenter.xml
[root@centos7 jenkins]#sed -i 's@https://updates.jenkins.io/download/@https://mirrors.tuna.tsinghua.edu.cn/jenkins/@g' /var/lib/jenkins/updates/default.json
# 修改后重启Jenkins
[root@ubuntu1804:~]# systemctl restart jenkins.service
