2. 拉取nexus3鏡像

docker pull docker.io/sonatype/nexus3

控制檯輸出

[root@xxx ~]# docker pull docker.io/sonatype/nexus3
Using default tag: latest
latest: Pulling from sonatype/nexus3
c65691897a4d: Pull complete 
641d7cc5cbc4: Pull complete 
c508b13320cd: Pull complete 
79e3bf9d3132: Pull complete 
Digest: sha256:2c33632ccd1f8c5f9023a3d7f5f541e211831e402219f8c5a83a29d1721457ca
Status: Downloaded newer image for sonatype/nexus3:latest
docker.io/sonatype/nexus3:latest

3. 查看鏡像

docker images

控制檯輸出

[root@xxx ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
sonatype/nexus3     latest              8eb898be2a53        2 weeks ago         611MB

4.運行nexus容器

docker run -id --privileged=true --name=nexus3 --restart=always -p 8081:8081 -v /wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3

控制檯輸出

[root@xxx ~]# docker run -id --privileged=true --name=nexus3 --restart=always -p 8081:8081 -v /wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3
980f3759783f3ba7e59302848f816e371b229957f2c12b8f92934d468e061b00

解釋： -id 建立守護式容器 --privileged=true 授予root權限（掛載多級目錄必須爲true，不然容器訪問宿主機權限不足） --name=名字 給你的容器起個名字 -p 宿主機端口：容器端口映射 -v 宿主機目錄：容器目錄 目錄掛載 這裏須要些許時間才能啓動並訪問nexus 事機器配置而定 5.訪問nexus3 請先確保服務器的8081(視上面運行nexus容器時配置的端口而定)端口在安全組裏已開啓!!! 瀏覽器訪問http://ip:8081 6.登陸 進入nexus3頁面後右上角有個登陸的按鈕點擊顯示登陸框 nexus3默認的帳號依舊是admin可是密碼已經變了具體的密碼存儲在nexus3的容器的nexus-data路徑內的admin.password文件內 具體操做： 1.查看nexus3容器id

docker ps

控制檯顯示

[root@ecs-s6-xlarge-2-linux-20190927141629 ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
980f3759783f        sonatype/nexus3     "sh -c ${SONATYPE_DI…"   4 minutes ago       Up 4 minutes        0.0.0.0:8081->8081/tcp   nexus3

記下CONTAINER ID:980f3759783f 2.進入容器控制檯

docker exec -it 980f3759783f bash

控制檯顯示

[root@ecs-s6-xlarge-2-linux-20190927141629 ~]# docker exec -it 980f3759783f bash
bash-4.4$ ls
bin   etc     lib       lost+found  nexus-data  root  srv  uid_entrypoint.sh  var
boot  help.1  lib64     media       opt         run   sys  uid_template.sh
dev   home    licenses  mnt         proc        sbin  tmp  usr

3.進入nexus-data文件夾

bash-4.4$ cd nexus-data/
bash-4.4$ ls
admin.password  db             generated-bundles  karaf.pid  log     restore-from-backup
blobs           elasticsearch  instances          keystores  orient  tmp
cache           etc            javaprefs          lock       port

4.打開admin.password 文件

bash-4.4$ vi admin.password

第一行就是密碼啦，複製密碼用admin賬號登陸，登陸之後系統會自動提示你更換admin的密碼
