一、Nexus
Nexus是一個強大的Maven倉庫管理器，它極大地簡化了自己內部倉庫的維護和外部倉庫的訪問。利用Nexus你可以只在一個地方就能夠完全控制訪問 和部署在你所維護倉庫中的每個Artifact。Nexus是一套“開箱即用”的系統不需要數據庫，它使用文件系統加Lucene來組織數據。Nexus 使用ExtJS來開發界面，利用Restlet來提供完整的REST APIs，通過m2eclipse與Eclipse集成使用。Nexus支持WebDAV與LDAP安全身份認證。
二、部署規划
| 服務器IP | 192.168.113.48 |
|---|---|
| 端口 | 8931 |
| 安裝目錄 | /home/work/docker-nexus |
| 數據映射目錄 | /home/work/docker-nexus/data |
三、安裝Nexus
-
創建安裝目錄，進入到安裝目錄中編輯並保存docker-compose.yml文件
vim docker-compose.ymlversion: '3' services: nexus: image: 'sonatype/nexus3' container_name: nexus restart: always environment: - TZ=Asia/Shanghai ports: - '8931:8081' volumes: - '/home/work/docker-nexus/data:/nexus-data' -
在安裝目錄下啟動服務

啟動后查看日志，發現提示權限不足，為數據映射目錄加上權限即可
[root@node03 docker-nexus]# chmod 777 /home/work/docker-nexus/data/ You have new mail in /var/spool/mail/root [root@node03 docker-nexus]# docker-compose ps Name Command State Ports ----------------------------------------------------------------------- nexus sh -c ${SONATYPE_DIR}/star ... Up 0.0.0.0:8931->8081/tcp
四、驗證Nexus
-
在瀏覽器中輸入IP:端口，點擊頁面右上角登錄，根據頁面提示查找到初始密碼，然后將初始密碼復制
若輸入ip:端口后，瀏覽器無法訪問頁面，可以稍等一會，查看日志確保nexus啟動完成后再訪問
[root@node03 docker-nexus]# cat data/admin.password b05c1771-6be1-4cb2-9b4e-5cffb610099d
-
登錄后會有一個彈窗，要求給admin用戶重新設置一個新的密碼，請記住這個設置的密碼（本次安裝設置的密碼為admin_qazwsx）
-
點擊"next"，彈窗提示是否允許匿名用戶訪問，根據自己需求選擇即可，本次安裝選擇"開啟匿名訪問"
-
Nexus安裝成功，再根據需求進行相關配置即可。
