Jenkins-部署java代碼項目

實驗環境：

Jenkins：192.168.1.12

tomcat：192.168.1.7

 

1、新建遠程代碼Java項目倉庫

 

說明：這邊測試是在coding上註冊帳戶，創建遠程倉庫，coding地址： https://coding.net/login ，也可使用gitlub和github做爲遠程倉庫，自由選擇。

 

1：新建test-java項目

 

 

2：在Jenkins機器上生成祕鑰對

[root@Jenkins ~]# ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /root/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

a6:08:32:2e:1d:a6:85:bb:7e:64:dd:92:f7:60:b2:67 root@ghs

The key’s randomart image is:

+–[ RSA 2048]—-+

| |

| |

| |

| . |

|+ = . o S |

|.O = * B |

|+.+ . B o |

|.. . . E . |

|o.. o |

 

3：將id_rsa.pub公鑰內容複製到遠程倉庫上

[root@jenkins .ssh]# cat id_rsa.pub

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDy68qc7DtK09hWzrEv0jJXI28sluvpOK8oGR7Dhz2JDvbAxZ2jalipalIAxt8Hg3GbqYrzJIi6MTEYMbCKA7/XJ07dDfGvvwEnEyZb9fp1xgVzFCe5Vx9K5Qll/FpP0XtLK69QGMjrA1dsG1DRPyGqAySlYLo66TziSTG/RYI6NEPf40i7qaBQXobTNXj9Rv0b4fkJXlWHMZ+4zvo37UhhsgRt2SKJRupoKJpbONf3+H1u35KSsu5D5Qd4u7RCRJW2JGj9zyJt5VUiCUzQkyYiHRwarETC0HHGaqgFQltUJBC4SGkYVmYp3PDKZfhYNBE+JFvSJxkdz3Gyj63O9Nqz root@host1

 

 

4：Jenkins機器上建立java項目目錄，並操做初始化和克隆遠程倉庫

[root@jenkins ~]# mkdir /home/java

[root@jenkins test-java]# git clone git@e.coding.net:ghs-test/test-java.git

正克隆到 'test-java'...

warning: 您彷佛克隆了一個空版本庫。

[root@jenkins test-java]# cd test-java

[root@jenkins test-java]# echo "# test-java" >> README.md

[root@jenkins test-java]# git add README.md

[root@jenkins test-java]# git commit -m "first commit"

[master（根提交） c286ffe] first commit

1 file changed, 1 insertion(+)

create mode 100644 README.md

[root@jenkins test-java]# git push -u origin master

Counting objects: 3, done.

Writing objects: 100% (3/3), 213 bytes | 0 bytes/s, done.

Total 3 (delta 0), reused 0 (delta 0)

To git@e.coding.net:ghs-test/test-java.git

* [new branch] master -> master

分支 master 設置爲跟蹤來自 origin 的遠程分支 master。

 

 

2、下載zrlog的Java包

 

1：Jenkins上下載zrlog

[root@jenkins test_java]# wget https://codeload.github.com/94fzb/zrlog/zip/master

[root@jenkins test_java]# ls

master README.md

 

2：unzip解壓

[root@jenkins test_java]# unzip master

 

3：提交到遠程倉庫

[root@jenkins test-java]# git add .

[root@jenkins test-java]# git commit -m "add zrlog"

[root@jenkins test-java]# git push -u origin master

Counting objects: 606, done.

Compressing objects: 100% (554/554), done.

Writing objects: 100% (605/605), 1.89 MiB | 0 bytes/s, done.

Total 605 (delta 80), reused 0 (delta 0)

remote: Resolving deltas: 100% (80/80), done.

To git@e.coding.net:ghs-test/test-java.git

c286ffe..84a7318 master -> master

分支 master 設置爲跟蹤來自 origin 的遠程分支 master。

 

4：遠程倉庫上查看是否存在zrlog

 

 

3、安裝maven編譯打包

maven官網下載地址： https://maven.apache.org/download.cgi

 

1：下載maven二進制包

[root@jenkins src]# wget https://www-eu.apache.org/dist/maven/maven-3/3.6.2/source/apache-maven-3.6.2-bin.tar.gz

 

2：解壓

[root@jenkins src]# tar zxvf apache-maven-3.6.2-bin.tar.gz

 

3：移動到/usr/local目錄下

[root@jenkins src]# mv apache-maven-3.6.2 /usr/local/maven

 

4：執行mvn -v，檢查maven是否配置成功

[root@jenkins src]# /usr/local/maven/bin/mvn -v

Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T23:06:16+08:00)

Maven home: /usr/local/maven

Java version: 1.8.0_222, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64/jre

Default locale: zh_CN, platform encoding: UTF-8

OS name: "linux", version: "3.10.0-957.27.2.el7.x86_64", arch: "amd64", family: "unix"

 

4、配置tomcat

 

1：設置tomcat管理界面用戶和密碼，用戶admin，密碼abc-123。

[root@tomcat ~]# vim /usr/local/tomcat/conf/tomcat-users.xml

加入如下內容

<role rolename="admin"/>

<role rolename="admin-gui"/>

<role rolename="admin-script"/>

<role rolename="manager"/>

<role rolename="manager-gui"/>

<role rolename="manager-script"/>

<role rolename="manager-jmx"/>

<role rolename="manager-status"/>

<user name="admin" password="abc-123" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />

 

2：開放管理界面訪問IP限制，讓Jenkins能夠訪問管理界面並部署

[root@tomcat src]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml

修改成如下內容

allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1| 192.168.1.*" />

 

5、配置Jenkins

 

1：安裝完成後，到Jenkins web頁面配置maven

 

 

 

 

2：設置jdk路徑，這邊是存在在/usr/local/目錄下

 

 3：構建Maven項目前，需先安裝Maven Integration 和Deploy to container這兩個插件

 

 

 

6、構建job任務，實現部署Java代碼項目

 

1：構建test_java項目job

 

2：配置git，username：git用戶、Private key選擇Enter dirctly，私鑰和你Git服務器中存放的公鑰是配對的。

 

3：設置POM，Root POM爲pom.xml, Goals and options 填寫 clean install -D maven.test.skip=true

Post Steps、構建設置保持默認。

 

4：構建後操做，點擊「增長構建後操做步驟—選擇Deploy war/ear to a container選項

5：WAR/EAR files」填寫「**/*.war」，Contex path留空，Containers選擇須要發佈對應的tomcat，這邊是9.0版本，Cretentials配置tomcat的管理界面用戶名和密碼

6：Tomcat URL填寫要把war包發佈到的那臺機器的url，如http://192.168.1.13

 

 7：保存以後，返回項目首頁，點擊執行biud now開始部署，便可發佈到遠程機器上
