nexus3 docker部署 log

搭建私服好处

1. 方便团队协作，A开发完成的代码，提交的私服上，B添加pom.xml就可以使用A的代码了
2. 公司内部员工，不需要连接外网就可以从内网拉取依赖了。

安装步骤

1. 查看镜像

docker search nexus3

查询内容

[dingguo@dingguodeMacBook-Pro:~]$ docker search nexus3
NAME                                  DESCRIPTION                                     STARS               OFFICIAL            AUTOMATED

home1oss/nexus3                       An auto configured nexus3                       2                                       [OK]
madmuffin/nexus3                      Sonatype Nexus3 Milestone7 docker image         2                                       [OK]

2. 拉取第一个镜像

docker pull sonatype/nexus3

3.查看镜像

[dingguo@dingguodeMacBook-Pro:~]$ docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             SIZE
sonatype/nexus3                    latest              87d9a097d22c        2 weeks ago         634MB

4. 修改镜像名称

docker tag sonatype/nexus3 nexus3

查看镜像

[dingguo@dingguodeMacBook-Pro:~]$ docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             SIZE
nexus3                             latest              87d9a097d22c        2 weeks ago         634MB

5. 创建容器

docker run -id --privileged=true --name=nexus3 --restart=always -p 8081:8081 -v /Users/dingguo/nexus3/nexus-data:/var/nexus-data 87d

查看docker日志

docker logs -f 9b

会返回一大串的内容，等几分钟，直到出现下面表示启动成功

6. 在页面输入地址  http://localhost:8081/

点击右上角登录，默认账号/密码，admin/admin123

如果出现报错：如下

解决方案：

进入容器内部，查看 /nexus-data/admin.password

docker exec -it b8 bash

bash-4.4$ dir
bin   dev  help.1  lib	  licenses    media  nexus-data  proc  run   srv  tmp		     uid_template.sh  var
boot  etc  home    lib64  lost+found  mnt    opt	 root  sbin  sys  uid_entrypoint.sh  usr
bash-4.4$ more nexus-data/admin.password 
e7a42a55-6188-4dea-bad7-3989998f03b5
bash-4.4$

在页面输入密码：e7a42a55-6188-4dea-bad7-3989998f03b5

登录成功会弹出框，点击next，输入新的密码就可以了。

Nexus私服配置

如果我们要把写好的代码传到私服上，怎么配置呢？

1. 查看我们Nexus私服的地址

点击 maven-public 一行的copy，将地址复制保存

2. 修改maven的settings.xml文件

找到 settings.xml 文件，打开，需要添加两个部分

第一个部分

配置nexus私服地址,<url>标签的地址是 maven-public

<!-- Nexus私服配置 -->
<profile>
    <id>dev</id>
    <repositories>
        <repository>
            <id>nexus</id>
            <url>http://localhost:8081/repository/maven-public/</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
    </repositories>
</profile>

第二个部分

配置 Nexus私服发布的用户名密码，和私服登录密码一致

<!-- Nexus私服发布的用户名密码 -->
</servers>
  <server>  
    <id>maven-releases</id>  
    <username>admin</username>  
    <password>123456</password>  
  </server>  
  <server>  
    <id>maven-snapshots</id>  
    <username>admin</username>  
    <password>123456</password>  
  </server> 
</servers>

ok，settings.xml的配置就完成了。

2. 配置pom.xml文件

同理复制下图地址

pom.xml新增内容

<!--私服仓库-->
<distributionManagement>
    <repository>
        <id>maven-releases</id>
        <name>Nexus Release Repository</name>
        <url>http://localhost:8081/repository/maven-releases/</url>
    </repository>
    <snapshotRepository>
        <id>maven-snapshots</id>
        <name>Nexus Snapshot Repository</name>
        <url>http://localhost:8081/repository/maven-snapshots/</url>
    </snapshotRepository>
</distributionManagement>

3. 编写代码测试

新增一个类 HelloNexus 

package com.wjx;

/**
 * @Description:
 * @Author: dingguo
 * @Date: 2020/1/10 下午12:40
 */
public class HelloNexus {
    
    public void hello(){
        System.out.println("this is test");
    }
}

接下来就是将代码推到私服，代码版本

如图，点击 deploy

当出现下面这个表示已经上传成功

进入 maven-release 如下图，表示代码已经上传成功

右下角会有maven的依赖，如果在其他项目使用，把依赖拷贝过去就可以使用了。

可能遇到的问题

如果，相同版本再点击deploy就会报错

解决方案：

再次上传就不报错了。

附上 settingx.xml 的完全配置

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
