Jenkins FAQ

在使用Jenkins的一些问题的整理

离线安装插件

http://updates.jenkins-ci.org/download/plugins/

http://mirror.bit.edu.cn/jenkins/plugins/

下载需要的plugin,选择匹配的版本号,下载到本地,然后打开:系统管理---插件管理—高级---找到”上传插件”(浏览,找到扩展名为.hpi的插件，上传之后默认直接就安装了。重启jenkins，安装的插件就可以使用了。

Q1. 关于添加node连接Slave时连接不上的原因
已经在Slave 上已经添加了authorized_keys文件，开始在连接时还是报错

A1. 修改authorized_keys权限

chmod 755 authorized_keys

Q2. 关于首次构建"ERROR: Timeout after 10 minutes"

ERROR: Timeout after 10 minutes
ERROR: Error cloning remote repo 'origin'

分析：

vim /etc/default/jenkins
JAVA_ARGS="-Djava.awt.headless=true -Dorg.jenkinsci.plugins.gitclient.Git.timeOut=60"

还是行不通。其实这个与git clone下载没有多大关系，而是SSH 连接限制时间造成，由于一般的项目代码Code 都比较大，出错的项目code包含.git目录有20G。

A2:
在项目配置下 Additional Behaviours-->Add 添加-->Advanced clone Behaviours-->Timeout (in minutes) for clone and fetch operation 修改时间
