1、通过 RPM 安装 docker 17.03.0 版本并且配置 docker 阿里加速
[root@centos7 ~]#wget -P /etc/yum.repos.d/ https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@centos7 ~]#yum install -y --setopt=obsoletes=0 docker-ce-17.03.1.ce-1.el7.centos docker-ce-selinux-17.03.1.ce-1.el7.centos
[root@centos7 ~]#systemctl enable --now docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
[root@centos7 ~]#docker version
Client:
Version: 17.03.1-ce
API version: 1.27
Go version: go1.7.5
Git commit: c6d412e

[root@centos7 ~]#mkdir -p /etc/docker
[root@centos7 ~]#tee /etc/docker/daemon.json <<EOF
> {
> "registry-mirrors":["https://fof8w27e.mirror.aliyuncs.com"]
> }
> EOF
[root@centos7 ~]#systemctl daemon-reload
[root@centos7 ~]#systemctl restart docker
2、通过 docker 安装一个 LAPM 架构
[root@centos7 ~]#docker search -s 10 lamp
Flag --stars has been deprecated, use --filter=stars=3 instead

[root@centos7 ~]#mkdir /mysql_data
[root@centos7 ~]#docker run -d --name=lamp -p 80:80 -p 3306:3306 -v /mysql_data:/var/lib/mysql docker.io/mattrayner/lamp
[root@centos7 ~]#docker exec -it lamp bash
root@f7abb18696ca:/# mysql_secure_installation
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: y
There are three levels of password validation policy:
LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0
New password:
Re-enter new password:
Estimated strength of the password: 50
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
Remove anonymous users? (Press y|Y for Yes, any other key for No) :y
Normally, root should only be allowed to connect from
‘localhost‘. This ensures that someone cannot guess at
the root password from the network.
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
... skipping.
By default, MySQL comes with a database named ‘test‘ that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
Remove test database and access to it? (Press y|Y for Yes, any other key for No) :y
- Dropping test database...
Success.
- Removing privileges on test database...
Success.
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
Reload privilege tables now? (Press y|Y for Yes, any other key for No) :y
All done!
该镜像是基于ubuntu1804系统的
查看php mysql apache都是哪个版本
root@f7abb18696ca:~# dpkg -l
得知
php7.4 MySQL5.7.30 apache2.4.29
下载个包查看端口信息
root@f7abb18696ca:/# apt-get install net-tools
查看端口
root@f7abb18696ca:/# netstat -aptn
Active Internet connections (servers and established)

root@f7abb18696ca:~# cd /var/www/html/
root@f7abb18696ca:/var/www/html# vim index.php
<?php
echo phpinfo();
?>
3、写出 docker run 命令的延申指令，如怎么在停止一个 docker 容器的时候自动删除该容器
[root@centos7 ~]#docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@centos7 ~]#docker run -it --rm centos bash
[root@719deb51f412 /]# exit
exit
[root@centos7 ~]#docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4、写出 docker run 命令在自动启动 docker 服务时通过什么参数能够启动 docker 中的容器，从而实现容器随着 docker 服务的启动而自动启动
[root@centos7 ~]#docker run -d --name centos1 --restart=always centos
