Jenkins 第一次访问时提示Unlock Jenkins

Jenkins启动后，录入网址提示：Unlock Jenkins，To ensure Jenkins is securely set up by the administrator, a password has been written to the log (not sure where to find it?) and this file on the server:
 C:\Users\123\.jenkins\secrets\initialAdminPassword，Please copy the password from either location and paste it below.

解决办法：C:\Users\123\.jenkins\secrets\initialAdminPassword去这个路径下找到password，复制粘贴到unlock的页面上即可。

也许打开initialAdminPassword会报错，提示“系统找不到指定的路径”，我猜是文件夹访问的问题，此时我们把initialAdminPassword复制到桌面再打开就可以了。
