CentOS7下安装配置Jenkins(rpm包) 并新建项目打包到nexus

一、安装

Jenkins官网下载地址： https://jenkins.io/download/

rpm -ivh jenkins-2.138-1.1.noarch.rpm

二、配置

1. jenkins的默认JENKINS_PORT是8080，JENKINS_AJP_PORT默认端口是8009，这同tomcat的默认端口冲突。我这更改为8088和8089。

vi /etc/sysconfig/jenkins

2. 检测jdk是否安装，若没有安装jdk，则安装jdk

java -version

3. 检查jenkins是否配置jdk，在candidates后面加上自己的jdk路径，如下：

vi /etc/rc.d/init.d/jenkins

三、启动.

service jenkins start

------

http://192.168.84.131:8088

四、新建项目

1. 安装maven插件

系统管理 -> 插件管理 -> 可选插件： Maven Integration

2. 全局工具配置

settings.xml文件添加：

<servers>
<server>
<id>releases</id>
<username>admin</username>
<password>admin123</password>
</server>
<server>
<id>snapshots</id>
<username>admin</username>
<password>admin123</password>
</server>
<server>
<id>thirdparty</id>
<username>admin</username>
<password>admin123</password>
</server>
</servers>

<mirrors>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<name>192.168.84.131:8081</name>
<url>http://192.168.84.131:8081/nexus/content/groups/public</url>
</mirrors>

<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>central</id>
<url>http://192.168.84.131:8081/nexus/content/groups/public</url>
<releases><enabled>true</enabled></releases>
<snapshots><enabled>true</enabled></snapshots>
<thirdparty><enabled>true</enabled></thirdparty>
</repository>
</repositories>
</profile>
</profiles>

<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>

3. 新建maven项目

4. 该maven项目配置

if [ ${env} == "master" ]
then
mvn -B release:clean release:prepare release:perform
else
mvn clean
mvn deploy
fi

五、配置问题解决

1. Failed to connect to repository ...

(jenkins用户添加公钥)

A.由root切换到jenkins

passwd jenkins

su jenkins

B. 添加github公钥

执行： cd ~/.ssh

如果返回“… No such file or directory”，说明没有生成过SSH Key，直接进入D步。否则进入C步备份!

C. 备份： mkdir key_backup

mv id_isa* key_backup

D. 生成新的Key：（引号内的内容替换为你自己的邮箱） ssh-keygen -t rsa -C "[email protected]"

一直直接回车到生成公钥

E. cd ~/.ssh，打开“id_rsa.pub”

打开 https://github.com/settings/ssh ，点击 Add SSH Key 按钮，粘贴进去保存即可

id_rsa.pub 为公钥，id_rsa为私钥

F. jenkins中maven项目配置，复制私钥进去

2. Jenkins needs to know where your Maven is installed ....

全局工具配置 ->

3. 打包时出现 java找不到 ...

全局工具配置 ->

六、项目pom文件maven依赖

<scm>
 <connection>scm:git:[email protected]:jiekou0000/helloworld.git</connection>
 <developerConnection>scm:git:[email protected]:jiekou0000/helloworld.git</developerConnection>
 <url>https://github.com/jiekou0000/helloworld/tree/master</url>
 <tag>v1.0.0-SNAPSHOT</tag>
</scm>

<build>
 <pluginManagement>
  <plugins>
   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin</artifactId>
    <version>2.5.3</version>
    <configuration>
     <autoVersionSubmodules>true</autoVersionSubmodules>
     <tagNameFormat>v@{project.version}</tagNameFormat>
    </configuration>
   </plugin>
   <!--关闭java doc 警告-->

      </configuration>
     </execution>
    </executions>
   </plugin>

   <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
     <encoding>UTF-8</encoding>
    </configuration>
   </plugin>

   <plugin>

   </plugin>
  </plugins>
 </pluginManagement>
</build>

打包mster分支时会打包到nexus Releases下，必须先有SNAPSHOT版本
