Linux 使用nexus搭建maven私服

系统：LINUX

          JDK：已安装

          Maven：已安装

          Nexus

Nexus是一个强大的Maven仓库管理器，它极大地简化了自己内部仓库的维护和外部仓库的访问。

一、搭建

1.下载nexus

https://www.sonatype.com/download-oss-sonatype

2.上传到/root

3.解压

tar -zxvf nexus-3.12.1-01-unix.tar.gz -C /usr/local/

4.修改配置文件

♦端口

vim /usr/local/nexus-3.12.1-01/etc/nexus-default.properties

♦防火墙

vim  /etc/sysconfig/iptables
		-A INPUT -m state --state NEW -m tcp -p tcp --dport 8081 -j ACCEPT

5.登陆浏览器打开

http://192.168.56.102:8081/
	账号admin
	密码 admin123
	System Requirement: max file descriptors [4096] likely too low, increase to at least [65536].

6.修改ulimit

vim /etc/security/limits.conf
 	新增
 	* soft nofile 65535
	* hard nofile 65535

7.设置开机自启动

二、使用

1.仓库类型

proxy:代理仓库，用于代理远程仓库
group:仓库组，通常包含了多个代理仓库和宿主仓库，在项目中只要引入仓库组就可以下载到代理仓库和宿主仓库中的包
hosted:宿主仓库，内部项目、付费jar
	releases  发布内部release版本的仓库
	snapshots 发布内部snapshots版本的仓库
	third 自建第三方jar

2.配置代理

选择阿里云http://maven.aliyun.com/nexus/content/groups/public/

3.本地maven配置

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 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">

            </pluginRepository>
        </pluginRepositories>
    </profile>
</profiles>

</settings>

4.修改pom

<!--pom.xml 远程仓库的配置  id要跟本地maven的setting.xml相同 -->
  <distributionManagement>
        <repository>
            <id>releases</id>
            <name>Ruizhi Release Repository</name>
            <url>http://192.168.56.101:8081/repository/maven-releases/</url>
        </repository>

        <snapshotRepository>
            <id>snapshots</id>
            <name>Ruizhi Snapshot Repository</name>
            <url>http://192.168.56.101:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

5.测试是否nexus搭建成功

pom添加本地没有的依赖，看nexus会不会代理
mvn deploy 看是否成功推送至nexus

三、nexus图片观赏

　　

　　

四、pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
