工具详解 - Jenkins+Gitlab

我在尝试在容器中安装Jenkins时，初衷是希望使用docker in docker 的模式来实现Jenkins slave容器按需创建。在实现的时候需要在Jenkins 中安装Kubernetes插件。 kubernetes的插件目前来看存在一个Bug，这个bug很小但是会导致我们无法设置和kubernetes mastert认证的机制。Bug是由于配置代理时候是用的IP地址，但是jenkins必须加入http协议，可惜的是加入http协议后更新的代理又不能使用了，进入这种死循环了。所以这种方案暂时搁置。

So，这里我会写常用的实现自动化部署的方案之Jenkins+Gitlab这种模式，在小型的开发时候完全够用了，从来没有一致的最佳方案，只有适不适合咱们的团队方案。

Jenkins的安装

RedHat Linux RPM packages for Jenkins - https://pkg.jenkins.io/redhat-stable/

To use this repository, run the following command:

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

If you've previously imported the key from Jenkins, the "rpm --import" will fail because you already have a key. Please ignore that and move on.

You will need to explicitly install a Java runtime environment, because Oracle's Java RPMs are incorrect and fail to register as providing a java dependency. Thus, adding an explicit dependency requirement on Java would force installation of the OpenJDK JVM.

2.54 (2017-04) and newer: Java 8 1.612 (2015-05) and newer: Java 7 With that set up, the Jenkins package can be installed with:

yum install jenkins

See Wiki for more information, including how Jenkins is run and where the configuration is stored, etc.

Gitlab的安装

自己网上找吧，但是安装8.0+的版本，因为后面webhooks是有版本的要求的。

自动化部署配置

创建普通编译Job

Jenkins创建一个Job，并配置git信息

注意，这里连接Gitlab需要配置认证

同时，保证jenkins机器安装了Java， maven。

Maven 中需要配置成我们自己的仓库，配置settings.xm即可。

[root@jenkins ~]# find / -name settings.xml
/etc/maven/settings.xml
/var/lib/jenkins/.m2/settings.xml
/usr/share/maven/conf/settings.xml
[root@jenkins ~]# cat /usr/share/maven/conf/settings.xml

更改成公司artificatory配置

   <mirror>
      <id>mirrorId_2</id>
      <mirrorOf>*</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
    </mirror>-->
   <mirror>
      <id>mirrorId_1</id>
      <mirrorOf>*</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://139.24.120.251:58086/artifactory/list/maven2/</url>
    </mirror>

加入CI Trigger功能

Jenkins Trigger配置

Gitlab配置webhook

测试webhook:

加入CD功能

自动化运行脚本编写

[root@jenkins ~]# cat run.sh
#!/bin/bash
echo 'Checking scic document system status...'
SCIC_APP_PID=$(ps -ef | grep scic_paas_doc | grep -v grep | awk '{ print $2 }')
if [ -z "$SCIC_APP_PID" ]
  then
      echo Starting scic document...
      nohup java -jar scic_paas_doc-0.0.1-RELEASE.jar > doc.log 2>&1 &
      echo Started successfully.
else
    echo killing old service -  $SCIC_APP_PID ...
    kill $SCIC_APP_PID
    echo Restarting scic document...
    nohup java -jar scic_paas_doc-0.0.1-RELEASE.jar > doc.log 2>&1 &
    echo Restarted successfully.
fi

Global配置SSH Server

Build Job中配置PostBuild，Over SSH

通过SSH上传jar，并使用脚本运行

更新并提交代码
