解决方案：

先把容器删除

docker rm nexus

再运行启动新命令

在原先的命令基础上加了“--privileged=true”

docker run -p 8081:8081 --privileged=true --name nexus -v /usr/local/docker/nexus/nexus-data:/nexus-data 8716903d1912

注：--privileged，该参数可以设置是否给docker容器特权，如果该参数为true，使得docker容器内的root权限为宿主机的root权限，而非只是容器内的root权限

看下服务是否启动正常

docker ps

为挂载的路径赋权限：

chmod 777 /usr/local/docker/nexus/nexus-data

场景：

给技术经理找了几款Docker开源镜像仓库，为什么经理选中了Sonatype Nexus(上)
