【持续集成】jenkins安装部署从git获取代码
一:持续集成的概念:
1.1:总体的概括
持续集成Continuous Integration 持续交付Continuous Delivery 持续部署Continuous Deployment
1.2:什么是持续集成:
持续集成是指开发者在代码的开发过程中,可以频繁的将代码部署集成到主干,并进程自动化测试
1.3:什么是持续交付:
持续交付指的是在持续集成的环境基础之上,将代码部署到预生产环境
1.4:持续部署:
在持续交付的基础上,把部署到生产环境的过程自动化,持续部署和持续交付的区别就是最终部署到生产环境是自动化的。
二:安装部署持续集成工具jenkins:
2.1:安装部分:
2.1.1:执行安装:
下载jdk-8u111-linux-x64.rpm
# rpm -ivh jdk-8u111-linux-x64.rpm # vim /etc/profile export JAVA_HOME=/usr/java/jdk1.8.0_111 export PATH=$JAVA_HOME/bin:$PATH
安装jenkins
方法①yum方式安装
# cd /etc/yum.repos.d/ # wget http://pkg.jenkins.io/redhat/jenkins.repo # rpm --import http://pkg.jenkins.io/redhat/jenkins.io.key # yum install -y jenkins # systemctl start jenkins
方法②通过war包的方式安装下载地址:http://updates.jenkins-ci.org/download/war/2.60.1/jenkins.war
unzip apache-tomcat-8.0.37.zip mv apache-tomcat-8.0.37 /usr/local/ cd /usr/local ln -s /usr/local/apache-tomcat-8.0.37 /usr/local/tomcat useradd jenkins # 将jenkins.war放到/usr/local/tomcat/webapps目录下,解压 unzip -d jenkins jenkins.war chown -R jenkins.jenkins /usr/local/apache-tomcat-8.0.37 bin/startup.sh
2.1.2:打开web界面:第一次打开要输入随机生成的密码:
http://192.168.3.199:8080/jenkins
查看密码
$ cat /home/jenkins/.jenkins/secrets/initialAdminPassword 8743f91ff1474a85a0abcd841fc74eb6
输入密码点下确认之后选择插件,选择默认安装插件即可,此过程需要一段时间,而且根据网络不同有些插件安装不成功,但是之后可以自己再安装即可
报错:
An error occurred
An error occurred during installation: No such plugin: cloudbees-folder
解决办法:
下载cloudbees-folder.hpi放在目录/usr/local/tomcat/webapps/jenkins/WEB-INF/detached-plugins/下,重启tomcat即可
设置用户名密码
3.1配置邮件通知,系统管理–系统设置
添加管理员邮箱,添加邮件
点击保存或测试邮件,系统会给目标邮箱发送一封测试邮件:
安装gitlab插件,系统管理–管理插件–可选插件
插件安装界面,会额外安装一些依赖关系的插件,jenkins基于ruby开发,所以会有ruby环境:
在gitlab管理界面将用户添加到一个项目,下一步要用此用户拉取项目代码
三:使用jenkins:
3.1:添加一个认证用户,拉取git代码的时候使用:
创建任务 --> 构建一个自由风格的软件项目
项目描述信息:
配置git项目地址,我们先进行其他配置,等会再继续配置git相关的选项
系统管理 --> Global Tool Configuration
Kind 选择 SSH Username with private key
Username 填 root
PrivateKey 选择 From a file on jenkins master ,然后将服务器的 私钥的存放路径(私钥、私钥、私钥,再说三遍) 粘贴进去
passphrase 填创建SSH秘钥时的设置的密码,未设置可不填
如果没报错,说明成功了,点击页面底部的“apply”。如果出错了,会在“Repository URL”和“Credentials”之间显示红色的错误信息。
jenkins job默认对master分支进行构建,你也可以自定义分支。这要求你的Gitlab代码仓库中要存在这个分支,一般来说,就是要向代码仓库提交一次更改,请 自行完成(Gitlab项目刚创建时是空的,一个分支也没有,这样的话,自动构建时会出错)

如下配置,jenkins服务器上root用户生成密钥对
[root@node1 ~]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub.

查看公钥,id_rsa.pub是公钥。文件中的内容就是公钥。
gitlab上配置web-demo项目设置private deploy key
把key复制进去,同时title起一个简单明了的名字
在jenkins服务器192.168.3.199上测试下是否能够正常获取代码
[root@node1 tmp]# git clone git@192.168.3.198:web/web-demo.git Cloning into 'web-demo'... The authenticity of host '192.168.3.198 (192.168.3.198)' can't be established.

jenkins拉取代码没问题,继续配置jenkins的认证,这里应该输入私钥
复制jenkins拉取git代码服务器root的私钥

添加描述,点击OK
继续编辑配置
这样就不报错了,下面还可以指定从哪个分支拉取,默认从master拉取,有些公司使用release分支
源码浏览器,去gitlab上找到http的url:http://192.168.3.198/web/web-demo.git
找出gitlab的版本,输入url和版本,版本只支持2位,拉到最下面保存
[root@web01 ~]# rpm -qa|grep gitlab gitlab-ce-8.10.5-ce.0.el7.x86_64
点击立即构建,查看控制台,可以看到构建的详细输出
