拉取nexus3镜像

docker pull docker.io/sonatype/nexus3

控制台输出

[root@xxx ~]# docker pull docker.io/sonatype/nexus3
Using default tag: latest
latest: Pulling from sonatype/nexus3

Status: Downloaded newer image for sonatype/nexus3:latest
docker.io/sonatype/nexus3:latest

查看镜像

docker images

控制台输出

[root@xxx ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

4.运行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

控制台输出

[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

解释： -id 创建守护式容器 --privileged=true 授予root权限（挂载多级目录必须为true，否则容器访问宿主机权限不足） --name=名字给你的容器起个名字 -p 宿主机端口：容器端口映射 -v 宿主机目录：容器目录目录挂载这里需要些许时间才能启动并访问nexus 事机器配置而定 5.访问nexus3 请先确保服务器的8081(视上面运行nexus容器时配置的端口而定)端口在安全组里已开启!!! 浏览器访问http://ip:8081

访问

6.登录进入nexus3页面后右上角有个登录的按钮点击显示登录框

nexus3默认的账号依旧是admin但是密码已经变了具体的密码存储在nexus3的容器的nexus-data路径内的admin.password文件内具体操作： 1.查看nexus3容器id

docker ps

控制台显示

[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
记下CONTAINER ID:980f3759783f

2.进入容器控制台

docker exec -it 980f3759783f bash

控制台显示

[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.进入nexus-data文件夹

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.打开admin.password 文件

bash-4.4$ vi admin.password

第一行就是密码啦，复制密码用admin帐号登录，登录以后系统会自动提示你更换admin的密码
