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。
