第7章 Jenkins与Nexus集成

Nexus3安装部署​

1.二进制安装JDK​

tar zxf jdk-8u351-linux-x64.tar.gz -C /opt/
ln -s /opt/jdk1.8.0_351 /opt/jdk
cp /etc/profile /etc/profile.bak
cat >> /etc/profile << 'EOF'
export JAVA_HOME=/opt/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=$PATH:${JAVA_HOME}/bin
EOF
source /etc/profile
java -version
echo $JAVA_HOME
echo $JRE_HOME

2.下载并安装Nexus​

安装命令：

tar zxf nexus-3.23.0-03-unix.tar.gz -C /opt/
cd /opt/
ln -s nexus-3.23.0-03 nexus

3.创建普通用户并更改权限​

useradd nexus -s /sbin/nologin
chown -R nexus:nexus /opt/nexus*
chown -R nexus:nexus sonatype-work

4.创建systemd启动服务​

cat >/usr/lib/systemd/system/nexus.service<<EOF
[Unit]
Description=nexus

[Service]
Environment=JAVA_HOME=/opt/jdk
ExecStart=/opt/nexus/bin/nexus start
ExecStop=/opt/nexus/bin/nexus stop
Type=forking
User=nexus
Group=nexus

[Install]
WantedBy=multi-user.target
EOF

5.修改JVM内存使用大小​

内存调整

默认2G内存，我们修改为1G。

vim /opt/nexus/bin/nexus.vmoptions
-Xms1024m
-Xmx1024m
-XX:MaxDirectMemorySize=1024m

6.启动并检查​

systemctl daemon-reload
systemctl start nexus
netstat -lntup|grep 8081
ps -ef|grep nexus

7.配置账户密码​

打开浏览器并登陆：http://10.0.0.202:8081/

登陆信息

默认账号为admin，初始密码保存在文件里：

cat /opt/sonatype-work/nexus3/admin.password

1717330507692-55e98d03-ade9-43a1-b993-e2689b403d79.webp

1717330507830-ec5d347a-69a3-466f-b602-a764383f7b53.webp

8.初始化操作​

登录后需要我们修改密码:

1717330507826-efa2d9f3-0d60-45ff-a11e-b0d085032cb7.webp

然后禁用匿名用户访问：

1717330507834-2d07db15-3a6b-4afd-a85e-e252ce44bfbe.webp

9.修改maven仓库地址​

1717330508767-6578c53c-4037-42dd-b65a-a99ff0e65fc1.webp

1717330508755-6df3dd24-b37c-4a5f-ab91-95823b4be852.webp

将代理地址修改为阿里源：

https://maven.aliyun.com/nexus/content/groups/public

10.复制maven-public地址​

1717330509236-1ce86fa6-5c93-4e82-83b2-c7bcdea59ddd.webp

11.将Maven配置文件提交到代码仓库里​

这里我们也可以把settins.xml文件放到代码目录里，以后随着代码拉取后让mvn命令指定settings.xml文件来进行构建

[root@jenkins-201 /opt/kaoshi]# ls
mvnw  mvnw.cmd  pom.xml  README.md  settings.xml  src

[root@jenkins-201 /opt/kaoshi]# cat settings.xml

[root@jenkins-201 ~/ansible_kaoshi]# cat jenkins_deploy.sh
#!/bin/bash

# 1.构建镜像
export JAVA_HOME=/opt/jdk8
/opt/maven/bin/mvn -s settings.xml clean package


# 2.代码扫描
if [ "$sonarSkip" == "false" ];then
  /opt/sonar-scanner/bin/sonar-scanner -Dsonar.host.url=http://10.0.0.203:9000 \
  -Dsonar.projectKey=kaoshi-maven-service \
  -Dsonar.projectName=kaoshi-maven-service \

# 3.替换系统变量
cd /root/ansible_kaoshi/
sed -i "/APP_VERSION=/c APP_VERSION=$releaseVersion" kaoshi.env
sed -i "/APP_ENV=/c APP_ENV=${deployEnv,,}" kaoshi.env


# 4.调用Ansible剧本
ansible-playbook -l $deployHosts ansible_kaoshi.yaml -e "app_version=$releaseVersion"

第2章 制品库实战

1.制品相关概念​

基本概念
  • 制品 → 编译后的代码包 → jar包
  • 制品库 → 按照一定规则存放制品的仓库 → nexus
  • SNAPSHOT → 还没有开发完毕，临时的版本
  • release → 已经开发完毕，可以直接对外发布

例如：

  • <version>3.9.3-SNAPSHOT</version>
  • <version>3.9.3-release</version>
  • xzs-3.9.0-SNAPSHOT.jar
  • xzs-3.9.0-release.jar

2.创建制品库​

1719736528095-e8d74c13-9228-44be-8f61-3935503b0d03.png

3.上传制品​

3.1 SNAPSHOT版本上传​

修改pom.xml文件为SNAPSHOT版本

[root@jenkins-201 /var/lib/jenkins/workspace/test-jdk]# cat pom.xml |grep SNAPSHOT
    <version>3.9.2-SNAPSHOT</version>

构建完成后查看jar包

[root@jenkins-201 /var/lib/jenkins/workspace/test-jdk]# ll target/
total 48576
drwxr-xr-x 5 root root      234 Jun 30 16:44 classes
drwxr-xr-x 3 root root       25 Jun 30 16:44 generated-sources
drwxr-xr-x 2 root root       28 Jun 30 16:44 maven-archiver
drwxr-xr-x 3 root root       35 Jun 30 16:44 maven-status
-rw-r--r-- 1 root root 40521522 Jun 30 16:44 xzs-3.9.2-SNAPSHOT.jar
-rw-r--r-- 1 root root  9218768 Jun 30 16:44 xzs-3.9.2-SNAPSHOT.jar.original

maven上传制品命令：

mvn -s settings.xml deploy:deploy-file \
-DgroupId=com.mindskip \
-DartifactId=xzs \
-Dversion=3.9.2-SNAPSHOT \
-Dpackaging=jar \
-Dfile=target/xzs-3.9.2-SNAPSHOT.jar \
-Durl=http://10.0.0.202:8081/repository/kaoshi-snapshot/ \
-DrepositoryId=snapshots

查看制品库中上传后的制品

3.2 RELEASE版本上传​

查看版本信息

[root@jenkins-201 /var/lib/jenkins/workspace/test-jdk]# cat pom.xml |grep "3.9.2"
    <version>3.9.2</version>

maven构建

mvn -s settings.xml clean package

查看构建后制品

[root@jenkins-201 /var/lib/jenkins/workspace/test-jdk]# ll target/
total 48576
drwxr-xr-x 5 root root      234 Jun 30 16:59 classes
drwxr-xr-x 3 root root       25 Jun 30 16:59 generated-sources
drwxr-xr-x 2 root root       28 Jun 30 16:59 maven-archiver
drwxr-xr-x 3 root root       35 Jun 30 16:59 maven-status
-rw-r--r-- 1 root root 40521496 Jun 30 16:59 xzs-3.9.2.jar
-rw-r--r-- 1 root root  9218741 Jun 30 16:59 xzs-3.9.2.jar.original

制品上传命令

mvn -s settings.xml deploy:deploy-file \
-DgroupId=com.mindskip \
-DartifactId=xzs \
-Dversion=3.9.2 \
-Dpackaging=jar \
-Dfile=target/xzs-3.9.2.jar \
-Durl=http://10.0.0.202:8081/repository/kaoshi-release/ \
-DrepositoryId=releases

4.下载制品​

4.1 下载SNAPSHOT版本制品​

因为SNAPSHOT制品有时间戳，所以需要先查询

curl -u admin:admin -X GET "http://10.0.0.202:8081/service/rest/v1/search/assets?repository=kaoshi-snapshot&maven.groupId=com.mindskip&maven.artifactId=xzs&maven.baseVersion=3.9.2-SNAPSHOT"

使用jq结构化解析查询结果:

[root@jenkins-201 ~/test]# curl -s -u admin:admin -X GET "http://10.0.0.202:8081/service/rest/v1/search/assets?repository=kaoshi-snapshot&maven.groupId=com.mindskip&maven.artifactId=xzs&maven.baseVersion=3.9.2-SNAPSHOT" | jq '.items[] | .downloadUrl'
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.jar"
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.jar.md5"
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.jar.sha1"
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.pom"
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.pom.md5"
"http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.pom.sha1"

获取到jar包地址后就可以下载了:

curl -s -u admin:admin -o xzs-3.9.2-SNAPSHOT.jar http://10.0.0.202:8081/repository/kaoshi-snapshot/com/mindskip/xzs/3.9.2-SNAPSHOT/xzs-3.9.2-20240630.085043-1.jar

4.2 下载release版本制品​

### 4.2 下载release版本制品
```bash
curl -s -u admin:admin -o xzs-3.9.2.jar http://10.0.0.202:8081/repository/kaoshi-release/com/mindskip/xzs/3.9.2/xzs-3.9.2.jar

5.使用插件获取版本信息​

安装插件Maven Artifact ChoiceListProvider (Nexus)可以动态列出nexus上的包列表

1719739065786-628bdf77-7298-4632-b5ba-baec1b7b64b4.png

在任务中，选择添加参数：Extensible Choice

1719739718106-8219e16b-6f21-444e-8291-7d668a6cd1b1.png

然后在Choice Provider中选择Nexus3

1719739691591-dce6105f-e0ff-48a2-a72e-ae884f34002d.png

最终执行时的效果:
