docker安装nexus3私有仓库
一、部署
安装nexus
docker pull sonatype/nexus3 docker run -dti --name nexus \ --restart=always \ -p 8081:8081 \ -p 8082:8082 \ -p 8083:8083 \ -p 8084:8084 \ -v /data/program/nexus3/nexus-data:/nexus-data \ sonatype/nexus3
二、设置
访问 http://IP地址:8081进入nexus3，登陆admin账户
创建Blob Stores，这里主要创建maven和docker的存储空间。
maven仓库配置
Browse可以查看当前有多少仓库，搭建好的Nexus，默认会带有一些maven仓库，一般使用这些仓库就足够了。
1.默认仓库说明
maven-central：maven中央库，默认从https://repo1.maven.org/maven2/拉取jar maven-releases：私库发行版jar，初次安装请将Deployment policy设置为Allow redeploy maven-snapshots：私库快照（调试版本）jar maven-public：仓库分组，把上面三个仓库组合在一起对外提供服务，在本地maven基础配置settings.xml或项目pom.xml中使用
2.仓库类型
Group：这是一个仓库聚合的概念，用户仓库地址选择Group的地址，即可访问Group中配置的，用于方便开发人员自己设定的仓库。maven-public就是一个Group类型的仓库，内部设置了多个仓库，访问顺序取决于配置顺序，3.x默认Releases，Snapshots， Central，当然你也可以自己设置。 Hosted：私有仓库，内部项目的发布仓库，专门用来存储我们自己生成的jar文件 3rd party：未发布到公网的第三方jar (3.x去除了) Snapshots：本地项目的快照仓库 Releases： 本地项目发布的正式版本 Proxy：代理类型，从远程中央仓库中寻找数据的仓库（可以点击对应的仓库的Configuration页签下Remote Storage属性的值即被代理的远程仓库的路径），如可配置阿里云maven仓库 Central：中央仓库 Apache Snapshots：Apache专用快照仓库(3.x去除了)
3.添加仓库
(1)按照步骤添加新的代理源
(2)选择添加maven2的代理
(3)添加代理（Cache统一设置为200天 288000）
(4)逐个增加常用代理
1. aliyun http://maven.aliyun.com/nexus/content/groups/public 2. apache_snapshot https://repository.apache.org/content/repositories/snapshots/ 3. apache_release https://repository.apache.org/content/repositories/releases/ 4. atlassian https://maven.atlassian.com/content/repositories/atlassian-public/ 5. central.maven.org http://central.maven.org/maven2/ 6. datanucleus http://www.datanucleus.org/downloads/maven2 7. maven-central （安装后自带，仅需设置Cache有效期即可） https://repo1.maven.org/maven2/ 8. nexus.axiomalaska.com http://nexus.axiomalaska.com/nexus/content/repositories/public 9. oss.sonatype.org https://oss.sonatype.org/content/repositories/snapshots 10.pentaho https://public.nexus.pentaho.org/content/groups/omni/
(5) 设置maven-public 将这些代理加入Group，最好将本地的maven库放到最上面
(6)设置私用仓库可重复发布
三、配置域名及nginx代理
1.设置域名解析
maven.example.com –>公网ip
2.编辑nginx配置文件
upstream nexus_web {
server 172.17.0.2:8081;
}
server {
listen 80;
server_name maven.example.com;
index index.html index.htm index.php;
access_log /var/log/nginx/maven.example.com.log main;
location / {
proxy_pass http://nexus_web;
proxy_set_header Host $host;
client_max_body_size 512m;
proxy_connect_timeout 3600;
proxy_send_timeout 3600;
proxy_read_timeout 3600;
proxy_buffering off;
proxy_request_buffering off;
}
}
四、使用
1.设置用户setting.xml文件
设置用户密码
<server> <id>releases</id> <username>admin</username> <password>admin</password> </server> <server> <id>snapshots</id> <username>admin</username> <password>admin</password> </server>
配置镜像
<mirror>

</mirror>
<mirror>
<id>central</id>
