系统环境：Centos 7
环境架构：docker 虚拟机
第一步：安装docker的yum源、
rpm -ivh http://aliyun.com/epel/centos7
第二步
安装docker
#yum install docker -y
查看docker都安装哪些包
#rpm -ql docker

最主要的就在/etc/docker 目录。关于docker安装就到此结束了
下面就是主角上场了。我们说的主题是使用docker环境下搭建nextcloud私钥云
下面介绍docker几个常用的命令吧
p_w_picpaths 查看本地镜像
pull 拉取仓库镜像
run --name 运行镜像的名字
-d 指运行的版本号
-p 端口号（注意：这里将本地端口映射到虚拟机的端口号）
-v 本地目录存储路径。这里也是将映射到虚拟机的目录路径
好了。就让我一起试下docker的强大之处吧
Nextcloud私钥云是一个开源的存储软件。
搭建架构是lamp lnmp
那我们从仓库到一个nextcloud镜像就可以了
首先，先下载一个数据库
docker pull mysql
运行与启动
docker run --name owncloud_db -v /data/owncloud_db:/var/lib/mysql:Z -e MYSQL_ROOT_PASSWORD=name -p 3306：3306 -d percona:5.7.11
查看镜像是否启动成功
docker ps -a
#d86a055a77a2 mysql "docker-entrypoint.sh" 9 days ago Up 9 days 0.0.0.0:3306->3306/tcp mysql
然后下载一个nextcloud镜像运行就可以了
#docker pull nextcloud
# docker run --name nextcloud -d -p 80:80 wonderfall/nextcloud
查看启动是否成功
5e492405ed62 wonderfall/nextcloud "/sbin/tini -- run.sh" 9 days ago Up 9 days 0.0.0.0:80->80/tcp distracted_kilby
好了。两个镜像都启动好了。
现在配置数据库添加一个nextcloud数据库让用户对它有执行权限。设置一个管理员用户密码。我们的nextcloud私钥云就搭建好了后续相信大家也比较简单我就没有做。我相信你们可以的。
