nexus repository oss 是免费的通用格式文件的存储库。

1.Docker安装

1.1 创建目录并授权

mkdir -p nexus3/sonatype-work/nexus3
chmod -R 777 nexus3

1.2 创建docker-compose.yml并将文件放在根目录

version: '3.8'
networks:
   nexus3:
    driver: bridge
services:
  nexus3:
    image: sonatype/nexus3:3.37.3
    container_name: nexus3
    restart: always
    environment:
            - "INSTALL4J_ADD_VM_PARAMS=-Xms1500m -Xmx1500m"
    volumes:
      - ./sonatype-work/nexus3:/nexus-data
    ports:
      - 8081:8081    
    networks:
      - nexus3

注：首次启动需要加载超多配置，启动时间很长，请耐心等待，切记不要退出，否则再次启动时会出现各种诡异的问题。

2.Centos安装

2.1 下载安装包

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

2.2 编辑配置文件

配置文件/nexus-3.xx.xx/etc/nexus-default.properties，默认开始http，可选开启https

## DO NOT EDIT - CUSTOMIZATIONS BELONG IN $data-dir/etc/nexus.properties
##
# Jetty section
nexus-context-path=/
application-host=0.0.0.0
# http端口
#application-port=8081
# http访问
#nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-http.xml,${jetty.etc}/jetty-requestlog.xml
# https端口
application-port-ssl=8081
# https访问
nexus-args=${jetty.etc}/jetty.xml,${jetty.etc}/jetty-https.xml,${jetty.etc}/jetty-requestlog.xml
# Nexus section
nexus-edition=nexus-pro-edition
nexus-features=\
 nexus-pro-feature

2.3 https配置（可选）

2.3.1 生成ssl证书

使用 nexus-ssl-generate-keystore.sh 生成ssl证书，将shell放在/nexus-3.xx.xx/根目录下。
nexus-ssl-generate-keystore.sh 脚本内容如下：

NEXUS_DOMAIN='Nexus'
if [[ -z $1 ]]; then
        echo 'please input your ip_address!'
        exit
fi
NEXUS_IP_ADDRESS=$1
PASSWORD='password'
keytool -genkeypair -keystore keystore.jks -storepass ${PASSWORD}  -keypass ${PASSWORD} -alias nexus -keyalg RSA -keysize 2048 -validity 5000 -dname "CN=${NEXUS_DOMAIN}, OU=Nexus, O=Nexus, L=Beijing, ST=Beijing, C=CN" -ext "SAN=IP:${NEXUS_IP_ADDRESS}" -ext "BC=ca:true"
mv keystore.jks etc/ssl/
#keytool -export -alias nexus -keystore keystore.jks -file keystore.cer -storepass ${PASSWORD}
#mv keystore.cer etc/ssl/

2.3.2 shell脚本使用方式

sh nexus-ssl-generate-keystore.sh {ip}

示例：

sh nexus-ssl-generate-keystore.sh 192.168.3.77

2.3.3 https证书

生成后的https证书存放位置：/nexus-3.xx.xx/etc/ssl/keystore.jks

2.4 启动

启动脚本：/nexus-3.xx.xx/bin/nexus
启动命令：./nexus {start | stop | run | run-redirect | status | restart | force-reload }

2.5 访问

http[s]://ip:port

3.nginx 域名映射

3.1 nginx配置maven私服

        upstream nexus3.com {
        server 127.0.0.1:8081;
    }
    server {
        access_log /var/logs/nexus3.access.log main; 
        error_log  /var/logs/nexus3.error.log error;
        listen 443 ssl;
        server_name  your domain; # 配置域名
        charset utf-8;
        ssl_certificate /path/ssl证书.pem; # 域名对应的ssl证书
        ssl_certificate_key /path/ssl证书.key; # 域名对应的ssl证书
        ssl_session_cache shared:SSL:1m;
        ssl_session_timeout 5m;
        #ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        # 阿里云加固建议
        ssl_protocols TLSv1.2;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_prefer_server_ciphers on;
        # 阿里云加固建议
        server_tokens off;
        location / {
            proxy_connect_timeout 60;
            proxy_send_timeout 60;
            proxy_read_timeout 60;
            proxy_pass https://nexus3.com/;
            proxy_set_header  Host  $host;
            proxy_set_header  X-Real-IP  $remote_addr;
            proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
        }
        }

4.开发环境集成Maven私服

4.1 开发环境maven配置

4.1.1 maven版本统一使用3.5.4

下载地址：https://dlcdn.apache.org/maven/maven-3/3.5.4/binaries/

4.1.2 配置maven环境变量

参考文档：https://www.runoob.com/maven/maven-setup.html

4.1.3 配置settings.xml，需要替换以下几个节点

4.1.3.1 maven依赖存放位置

<localRepository>/Users/username/repository</localRepository>

4.1.3.2 maven打包上传时需要验证管理员账号和密码

<server>
  <id>private-maven-snapshots</id>
  <username>username</username>
  <password>password</password>
</server> 
<server>
  <id>private-maven-releases</id>
  <username>username</username>
  <password>password</password>
</server>

4.1.3.3 镜像替换，第1个为自己私服主用，第2个为阿里云私服备用

<mirror>
  <id>privatenexus</id>
  <name>privatenexus</name>
  <mirrorOf>central</mirrorOf> 
  <url>https://your domain/repository/maven-public/</url>
</mirror>
<mirror>
  <id>aliyun</id>
  <name>aliyun</name>
  <mirrorOf>central</mirrorOf>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>

4.2 maven项目开发配置

在pom.xml中增加以下配置
注：snapshotRepository和repository，这2个节点下的id要与4.1.3.2的server节点下的id一致，才可以使用deploy命令打包上传

    <!-- 下载快照 -->
    <repositories>
        <repository>
            <id>private-maven-public</id>
            <name>private-maven-public</name>
            <url>https://your domain/repository/maven-public/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
            <releases>
                <enabled>true</enabled>
            </releases>
        </repository>
    </repositories>
    <!-- 打包上传 -->
    <distributionManagement>
        <snapshotRepository>
            <id>private-maven-snapshots</id>
            <name>private-maven-snapshots</name>
            <url>https://your domain/repository/maven-snapshots/</url>
        </snapshotRepository>
        <repository>
            <id>private-maven-releases</id>
            <name>private-maven-releases</name>
            <url>https://your domain/repository/maven-releases/</url>
        </repository>
        </distributionManagement>

4.3 手动上传jar包到Maven私服

参考下方截图，请使用有管理员权限的账号登录。红框中的选项一定要勾选，否则在项目中引用不了。
