系统版本
debian8.0
1、部署docker环境
- 配置并更新源，使用aptitude安装
deb http://mirrors.ustc.edu.cn/debian jessie main contrib non-free
deb-src http://mirrors.ustc.edu.cn/debian jessie main contrib non-free
deb http://mirrors.ustc.edu.cn/debian jessie-proposed-updates main contrib non-free
deb-src http://mirrors.ustc.edu.cn/debian jessie-proposed-updates main contrib non-free
deb http://mirrors.ustc.edu.cn/debian jessie-updates main contrib non-free
deb-src http://mirrors.ustc.edu.cn/debian jessie-updates main contrib non-free
deb [arch=amd64] https://download.docker.com/linux/debian jessie stable
- 配置Docker加速器
编辑配置文件
root@linux:~# vim /etc/default/docker
添加
DOCKER_OPTS="–insecure-registry $DOCKER_OPTS --insecure-registry registry.mirrors.aliyuncs.com"
重启dokcer服务
root@linux:~# systemctl restart docker
- 直接使用安装包安装，相关包位置：172.16.0.200:/opt/package，根据提示安装相关依赖包,涉及的安装包如下:

└── unattended-upgrades_0.83.3.2+deb8u1_all.deb
2、部署mysql 5.7
- mysql版本:5.7
使用docker下载mysql5.7 images：
root@linx:~# docker pull mysql：5.7
Using default tag: latest
latest: Pulling from library/mysql
be8881be8156: Pull complete
c3995dabd1d7: Pull complete

Digest: sha256:e42cbb3afa80aa210aa1245b930619c12641a8de57a486e6f1b11858307bd378
Status: Downloaded newer image for mysql:latest
- 启动mysql
root@linx:/data/mysql# docker run -d -p 3306:3306 -v /data/mysql/conf/:/etc/mysql -v /data/mysql/data-v5.7:/var/lib/mysql -v /data/mysql/add/:/opt/add -e MYSQL_ROOT_PASSWORD=R0ck9 --name mysqlv5.7 mysql:5.7
OPTIONS说明：
-d: 后台运行容器，并返回容器ID；
-p: 端口映射
--name="nginx-lb": 为容器指定一个名称；
-e username="ritchie": 设置环境变量；
- 容器查询
root@nextcloud:~# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d1a49bf5bf7b mysql:5.7 "docker-entrypoint.s…" 41 hours ago Up 4 hours 0.0.0.0:3306->3306/tcp mysqlv5.7
- 设置mysql远程连接
root@nextcloud:~# mysql -uroot -p

root@linux:~# mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
3、nextcloud
使用docker pull nextcloud下载最新的nextcloud images，同mysql
启动nextcloud镜像
root@linx:/data/nextcloud# docker run -d -p 80:80 -v /data/nextcloud/data/:/var/www/html/data -v /data/nextcloud/add/:/opt/add --name nextcloud-mysqlv5.7 --link mysqlv5.7 nextcloud
779071bb2789d19799a6e74a62cc2f1b02f2bf644d7330cb549e8ba1bf98585f
- 查看容器
root@linx:/data/nextcloud# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
779071bb2789 nextcloud "/entrypoint.sh apac…" 4 seconds ago Up 3 seconds 0.0.0.0:80->80/tcp nextcloud-mysqlv5.7
d1a49bf5bf7b mysql:5.7 "docker-entrypoint.s…" 18 minutes ago Up 18 minutes 0.0.0.0:3306->3306/tcp mysqlv5.7
- 进入容器
root@linux:~#docker exec -it 779071bb2789 bash
4、 修改之后提交images
- 在对docker中的应用配置进行修改之后，docker不会自动提交，需要使用docker commit命令来提交成新的images，以免当前运行的iamges出现问题之后导致数据或者配置丢失。
root@linux:~#docker ps 查看container_id
root@linux:~#docker commit container_id [new_images_name:tag ]
options：
-a, --author="" Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
-m, --message="" Commit message
- 如果需要使用新提交的images启动 命令docker run,具体见启动mysql nextcloud镜像，需要修改映射端口，也可以将已经运行的容器停止并删除，使用原来的启动命令，不需要任何修改
5、 常见问题
- 迁移或者回滚之后nextcloud跳到创建管理员账户界面,由于数据库中已经创建过管理员用户，目前可尝试将数据库nextcloud中表oc_users中管理员用户删除的方法，来重建管理员账户跳过创建管理员用户页：
root@linux:~# mysql> delete from oc_users where uid = 'admin';
