目的

Continuous integration as a practice of software development,Its fast and frequent integration allows products and projects to iterate at high speed while maintaining high quality.

而JenkinsAs an excellent open source continuous integration tool,provided for development、测试、Powerful automatic construction support for each role of operation and maintenance.

Testing is an important phase in continuous integration,使用JenkinsThe need to perform automated testing is self-evident,利用JenkinsDo an automated build（编译、打包、部署、自动化测试）Problems in software can be found early,Corresponding to testing left shift,The sooner the test is involved in the project phase,The less expensive it is to find and fix problems.

依赖安装

Java

 
由于Jenkins是基于Java开发,所以我们需要先安装JDK
JDK推荐使用1.8版本,Too high to support,If it is too low, you can only use the old versionJenkins

两种下载方式：
1.离线安装
JDK下载地址： Java Downloads

After downloading it will be via remote toolstarThe package is placed in the path specified by the server

在对应目录中进行tarUnpacking the package

tar zxf jdk-8u181-linux-i586.tar.gz

     

      
1.
     

If necessary, you can rename and move the extracted folder（非必要）

mv jdk1.8.0_181 /指定目录/指定文件夹

     

      
1.
     

2.在线安装
使用yum search jdkCommand to search for downloadableJDK安装包

 

After finding the corresponding version, download and install it online

yum install -y java-1.8.0-openjdk.x86_64

     

      
1.
     

安装完成后开始配置环境变量（This step is required for both offline and online installations）

编辑profile文件

vim /etc/profile

     

      
1.
     

Add variables at the very end of the file,内容如下：

export JAVA_HOME=/usr/local/jdk/jdk1.8.0_321
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

     

      
1.
      
2.
      
3.
      
4.
     

这里需要说明的是JAVA_HOMEThe address is configured according to the actual path of your installation,Don't get it wrong,Because the next three variables need to use the address in the first variable.

保存退出后,Use the command to modify the environment variables to take effect

source /etc/profile

     

      
1.
     

验证Java安装成功与否

java -version

     

      
1.
     

Maven

Maven是一个依赖管理工具,构建项目的时候MavenThe required dependencies are automatically downloaded and built.
 
MavenThe installation can also be divided into online and offline,方法和Java类似,这里不再赘述.
Maven下载地址： Downloading Apache Maven

安装完毕后,Still configure environment variables

编辑profile文件

vim /etc/profile

     

      
1.
     

Add variables at the very end of the file,内容如下：

export M2_HOME=/opt/server/apache-maven-3.8.5
export PATH=$PATH:$M2_HOME/bin

     

      
1.
      
2.
     

验证Java安装成功与否

mvn -v

     

      
1.
     

软件安装

Jenkis

下载地址： Jenkins Redhat Packages

Here is the introduction to useyum install的方式来进行安装,Other methods can also be viewed on this page

先添加Jenkins's official website source

创建jenkins.repo文件

vim /etc/yum.repos.d/jenkins.repo

     

      
1.
     

Add the following to the file：

[jenkins]
name=Jenkins-stable
baseurl=http://pkg.jenkins.io/redhat-stable
gpgcheck=1

     

      
1.
      
2.
      
3.
      
4.
     

安装Jenkins

yum install -y jenkins

     

      
1.
     

If necessary, it can be modified accordinglyJenkins配置文件（非必要）

vim /etc/sysconfig/jenkins

     

      
1.
     

这里可以修改Jenkinsprogram account

 

这里可以修改Jenkins的运行端口,默认为8080

 

完成后启动Jenkins

systemctl start jenkins

     

      
1.
     

 
查看服务状态

systemctl status jenkins

     

      
1.
