# 用Docker Compose方式安装Nexus 3 #

## 参考文档 ##

*  [https://www.dockerheart.com/r/sonatype/nexus3][https_www.dockerheart.com_r_sonatype_nexus3]
 *  [https://access.redhat.com/containers/\#/registry.connect.redhat.com/sonatype/nexus-repository-manager][https_access.redhat.com_containers_registry.connect.redhat.com_sonatype_nexus-repository-manager]
 *  [https://github.com/sonatype/docker-nexus3][https_github.com_sonatype_docker-nexus3]

## 前置条件 ##

Nexus 3推荐使用`4vCPU`

*  [https://help.sonatype.com/repomanager3/system-requirements][https_help.sonatype.com_repomanager3_system-requirements]

## 一键自动化安装脚本 ##

参见：

*  [https://github.com/cookcodeblog/OneDayDevOps/blob/master/components/nexus-docker/install\_nexus.sh][https_github.com_cookcodeblog_OneDayDevOps_blob_master_components_nexus-docker_install_nexus.sh]

## Nexus 3 Docker Compose文件 ##

参见：

*  [https://github.com/sonatype/docker-nexus3/blob/master/docker-compose.yml][https_github.com_sonatype_docker-nexus3_blob_master_docker-compose.yml]

一个整理好的`docker-compose.yml`例子：

version: '2'
    
    services:
      nexus:
          restart: always
          image: sonatype/nexus3:3.17.0
          volumes:
            - /srv/docker/nexus/nexus-data:/nexus-data:Z
          ports:
            - "8081:8081"

*  [https://github.com/cookcodeblog/OneDayDevOps/blob/master/components/nexus-docker/docker-compose.yml][https_github.com_cookcodeblog_OneDayDevOps_blob_master_components_nexus-docker_docker-compose.yml]

## 安装和运行Nexus ##

mkdir -p /opt/nexus
    cp docker-compose.yml /opt/nexus
    
    mkdir -p /srv/docker/nexus/nexus-data && chown -R 200 /srv/docker/nexus/nexus-data
    
    cd /opt/nexus
    docker-compose up -d

查看日志：

docker-compose logs -f

Debug:

docker-compose exec nexus /bin/bash

## 打开防火墙端口 ##

在防火墙上打开HTTP端口：

firewall-cmd --list-all
    
    # http port
    firewall-cmd --zone=public --add-port=8081/tcp
    firewall-cmd --zone=public --add-port=8081/tcp --permanent
    
    firewall-cmd --reload
    firewall-cmd --list-all

## 访问Nexus ##

在浏览器中访问http://<nexus\_host>:8081

缺省管理员账号是admin，执行命令`cat /srv/docker/nexus/nexus-data/admin.password`获取管理员缺省密码。

打开Admin / Security / Anonymous，勾选“Allow anonymous users to access the server“，来允许匿名访问Nexus拉取jar包。

## 配置Maven代理仓库和中央仓库同步 ##
