Jenkins及其所必备环境安装

Jenkins运行需要jdk环境，实现自动打包部署我们需要maven，因此我们除了安装jenkins还需要安装jdk和maven。自动化构建需要我们从代码仓库获取代码，因此Git也是必须的。

安装JDK8

yum install java-1.8.0-openjdk
yum install -y java-devel
java #检查是否安装成功

安装jenkins

首先我们需要下载Jenkins (opens new window)的war包，并上传到服务器中，我下载后上传到了我服务器的/usr/local/software/jenkins目录下

nohup java -jar jenkins.war >jenkinslog.log 2>&1 &  #运行jenkins

运行后，浏览器输入ip:8080访问jenkins

或者查看日志 cat nohup.out

等待两分钟左右出现安装插件的页面，然后安装推荐的插件，安装完成后按照提示创建第一个管理员用户

安装Maven

我们访问Maven官网 (opens new window)下载maven的安装包，并上传到/usr/local/software/maven目录下

cd /usr/local/software/maven
tar zxvf apache-maven-3.8.6-bin.tar.gz
mv apache-maven-3.8.6 maven
/usr/local/software/maven/maven/bin/mvn
/usr/local/software/maven/maven/bin/mvn -v #如果有版本信息代表安装成功

配置maven镜像

vim /usr/local/software/maven/maven/conf/settings.xml

将mirrors标签包裹的内容替换为如下内容

<mirror>
    <!--This sends everything else to /public -->
    <id>nexus</id>
    <mirrorOf>*</mirrorOf> 
    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>
<mirror>
    <!--This is used to direct the public snapshots repo in the 
          profile below over to a different nexus group -->
    <id>nexus-public-snapshots</id>
    <mirrorOf>public-snapshots</mirrorOf> 
    <url>http://maven.aliyun.com/nexus/content/repositories/snapshots/</url>
</mirror>
<mirror>
    <!--This is used to direct the public snapshots repo in the 
          profile below over to a different nexus group -->
    <id>nexus-public-snapshots1</id>
    <mirrorOf>public-snapshots1</mirrorOf> 
    <url>https://artifacts.alfresco.com/nexus/content/repositories/public/</url>
</mirror>

安装git

yum install git
