在启动Jenkins以后提示该Jenkins实例似乎已离线。

也没当回事就跳过了离线了

结果在安装插件全部报错这个....反正各种插件都连接超时

翻了很多文章我做了一下操作,终于连接上了

1.卸载,重新安装,找一个没有空格的目录(我是在Windows安装的Jenkins报错)

2.在启动以后,输入密码,然后界面在缓冲 / 提示实例离线的时候, 打开http://localhost:8080/pluginManager/advanced

在最下面设置http://mirror.esuni.jp/jenkins/updates/update-center.json,然后提交,然后chenk now一下

3.确定右下角不报红了,然后重启jenkins服务.

4.重新输入密码,然后等待.就好了

(最重要的是我开了fanqiang软件)灵感来自下面的连接,我安装Windows是在搜索不到这个路径和配置,liunx也可以参考一下找找看

解决：安装Jenkins时web界面出现该jenkins实例似乎已离线

 

 

 

二更解决版本:

即使fanqiang也有插件链接不上,那就手动复制那个下载连接 下载到本地.

连接失败,看到错误中的http://mirrors.jenkins-ci.org/plugins/locale/1.4/locale.hpi (就是插件下载)这种网址了么,自己手动放到浏览器打开,下载下来以后放到jenkins/plugins里面

然后到http://localhost:8080/pluginManager/advanced这个界面自己安装就好了
