一、安裝

Jenkins官網下載地址： https://jenkins.io/download/

rpm -ivh jenkins-2.138-1.1.noarch.rpm

二、配置

1. jenkins的預設JENKINS_PORT是8080，JENKINS_AJP_PORT預設埠是8009，這同tomcat的預設埠衝突。我這更改為8088和8089。

vi /etc/sysconfig/jenkins

2. 檢測jdk是否安裝，若沒有安裝jdk，則安裝jdk

java -version

3. 檢查jenkins是否配置jdk，在candidates後面加上自己的jdk路徑，如下：

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

三、啟動.

service jenkins start

------

http://192.168.84.131:8088

四、新建專案

1. 安裝maven外掛

系統管理 -> 外掛管理 -> 可選外掛 ： Maven Integration

2. 全域性工具配置

settings.xml檔案新增： 

<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專案

4. 該maven專案配置

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

五、配置問題解決

1. Failed to connect to repository ...

(jenkins使用者新增公鑰)

A.由root切換到jenkins

passwd jenkins

su jenkins

B. 新增github公鑰

執行： cd ~/.ssh

如果返回“… No such file or directory”，說明沒有生成過SSH Key，直接進入D步。否則進入C步備份!

C. 備份： mkdir key_backup

                  mv id_isa* key_backup

D. 生成新的Key：（引號內的內容替換為你自己的郵箱）   ssh-keygen -t rsa -C "[email protected]"

一直直接回車到生成公鑰

E. cd ~/.ssh，開啟“id_rsa.pub”

開啟 https://github.com/settings/ssh ，點選 Add SSH Key 按鈕，貼上進去儲存即可

id_rsa.pub 為公鑰，id_rsa為私鑰

F. jenkins中maven專案配置，複製私鑰進去

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

全域性工具配置 ->     

3. 打包時出現 java找不到 ...

全域性工具配置 ->    

六、專案pom檔案maven依賴

 <connection>scm:git:[email protected]:jiekou0000/helloworld.git</connection>
 <developerConnection>scm:git:[email protected]:jiekou0000/helloworld.git</developerConnection>

ps：案例專案      https://github.com/jiekou0000/helloworld

打包mster分支時會打包到nexus  Releases下，必須先有SNAPSHOT版本
