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
在这里插入图片描述
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
登录
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
