笔者官方没有下载成功，源码打包ui报错也没有成功

将下载的包上传到服务器，执行命令:

#将nexus 解压到/usr/local/ 目录
tar -zxvf nexus-3.54.1-01-unix.tar.gz -C /usr/local/
#创建nexus用户
useradd nexus
#更改/usr/local/目录的所有者未nexus
chown -R nexus:nexus /usr/local/nexus-3.54.1-01

jdk安装

#搜索jdk
yum search openjdk
#安装需要的jdk版本
yum install java-1.8.0-openjdk.x86_64
#安装成功查看jdk版本
java -version

3.运行

查看系统要求:https://help.sonatype.com/en/sonatype-nexus-repository-system-requirements.html#instance-resource-sizing-profiles

#切换用户 nexus
su - nexus
#进入到安装目录
cd /usr/local/nexus-3.54.1-01
#后台启动 nexus相关命令:{start|stop|run|run-redirect|status|restart|force-reload}
./bin/nexus start 
# 运行，关闭窗口程序停止运行，调试的时候使用
./bin/nexus run
#停止
./bin/nexus stop

4.nexus 配置

nexus 启动以后，访问web管理页面 http://ip:8081
点击右上角登录,弹出登录框，显示admin默认密码路径:/usr/local/sonatype-work/nexus3/admin.password

登录成功,根据向导设置
修改密码以后，设置匿名访问：

启用匿名访问意味着默认情况下，用户可以在没有凭据的情况下从存储库搜索、浏览和下载组件。请考虑对您的组织的安全影响。

禁用匿名访问应该谨慎选择，因为它需要所有用户和/或构建工具的凭据。

允许仓库部署和更新:

5.maven上传jar到nexus

本地settings.xml配置:

idea maven配置:
File->Settings->Maven->

创建maven项目，pom.xml新增部署仓库配置:

<!-- 指定项目的部署仓库 -->
    <distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://10.10.1.185:8081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://10.10.1.185:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

注意：id的内容需要和settings.xml配置中的server id一致

上传jar包到nexus：
方式一：选中项目-》右键->run Maven->deploy

方式二：maven命令

mvn clean deploy

上传成功:

注意：如果版本号是以 SNAPSHOT结尾的如"1.0-SNAPSHOT",部署成功，jar被部署到maven-snapshots仓库。以其他则部署到maven-releases仓库。

新建maven项目，添加最近上传的依赖:

 <dependency>
            <groupId>cn.nexus.demo</groupId>
            <artifactId>nexus-demo-biz2</artifactId>
            <version>3.0.0</version>
        </dependency>

执行打包命令:

mvn clean package

打包成功输出:
