jenkins

jenkins 市场占有率90%

gitlab和jekins的过程

提交代码到gitlab
jenkins触发器（可以是使用githook 主动触发，或者jenkins定时轮询gitlab）查看代码是否有变化，有变化以后会获取代码重新构建
自动或手动同步代码到需要部署的机器
利用shell脚本触发构建过程
jenkins就是写一些shell脚本，会在不同的过程中执行

jenkins 安装

可以利用待编包直接安装

修改配置后重启jenkins
修改jenkins的插件源

// /var/lib/jenkins/updates下的default.json
sed -i 's/www.google.com/www/baidu.com/g/' default.json
sed -i 's/updates.jenkins-ci.org\/download/mirrors.tuma.tsinghua.edu.cn\/jenkins/g' default.json

sed -i 's/updates.jenkins.io\/download/mirrors.tuna.tsinghua.edu.cn\/jenkins/g'  default.json

service jenkins restart

登录jenkins，首次登录会提示去某个路径查看密码，查看后填入即可
安装插件, 全选即可
创建管理员
然后创建实例进入管理页面
界面上提示错误的话，点击纠正
安装插件：gitlab、publish over ssh、git parameter

使用

新建任务，输入任务名
丢弃构建历史部分，配置构建缓存的保存天数或者个数
点源码管理，输入git仓库的地址
指定拉取的分支名，例如*/master
在jenkins上生成密钥加到gitlab上
构建选择ssh（先在Dashboard->系统管理->系统配置上创建所有的生产机器）
source file一般填入*/
remote directory 填入部署项目时候，要部署到的目录
exec command 里面填写shell命令，可以执行shell脚本，重新执行编译过程等
构建触发器：
- 轮询scm 定时去查看代码是否发生了变化，如果发生了变化，就更新，使用crontab格式填写日程表
- 定时构建，定时拉取，不管代码是否有更新，使用crontab格式填写日程表分钟小时日期月份星期
- 手工构建，在jenkins中手工点击构建
多台机器构建，点击add server
