vagrant + virtualbox安装centos环境+docker安装

1. 下载vagrant 并安装，安装完成后，输入vagrant回车查看是否安装成功

2. 下载virtualbox.box并安装，安装完成后。

3. 创建虚拟机文件夹，例如、F:/vmimg/first-docker-centos 在此目录下运行 vagrant init 生成Vagrantfile文件(可以自定义一些属性)

然后绑定centos的操作系统镜像virtualbox.box所在路径 

F:vmimgfirst-docker-centos>vagrant box add centos/7 E:BaiduNetdiskDownloadcentos7.0virtualbox.box
==> box: Box file was not detected as metadata. Adding it directly...
==> box: Adding box 'centos/7' (v0) for provider:
box: Unpacking necessary files from: file:///E:/BaiduNetdiskDownload/centos7.0/virtualbox.box
box:
==> box: Successfully added box 'centos/7' (v0) for 'virtualbox'!

输入vagrant list 查看当前box

F:vmimgfirst-docker-centos>vagrant box list
centos/7 (virtualbox, 0)

然后输入vagrant up命令创建并启动虚拟机

F:vmimgfirst-docker-centos>vagrant up

vagrant ssh 进入虚拟主机

F:vmimgfirst-docker-centos>vagrant ssh

[vagrant@localhost ~]$ sudo -i   切换到根目录

[root@localhost ~]# ip a   查看虚拟机ip等信息

exit退出到下面目录

F:vmimgfirst-docker-centos>vagrant ssh-config  查看配置信息
Host default
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no  设置为yes
IdentityFile F:/vmimg/first-docker-centos/.vagrant/machines/default/virtualbox/private_key
IdentitiesOnly yes

登录设置

vagrant ssh 见使用root用户登录：

查看centos一些相关信息

F:vmimgfirst-docker-centos>vagrant ssh-config
Host default
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile F:/vmimg/first-docker-centos/.vagrant/machines/default/virtualbox/private_key
IdentitiesOnly yes
LogLevel FATAL

Xshell连接：

Ip：127.0.0.1

port:2222

username:vagrant

password:vagrant

文件 identityfile所指向的路径

使用root用户登录：

sudu -i

vi /etc/ssh/sshd_config  查找 ESC /  输入Pass 回车 找到后 按i 修改

修改PasswordAuthentication yes  按esc ：wq保存即可

命令行输入passwd修改密码 root1234   账号 root  密码 root1234

systemctl restart sshd

root vagrant 登录

BOX打包分发：

01退出虚拟机  vagrant halt

02打包 vagrant package --output first-docker-centos.box

03得到first-docker-centos.box

04 将first-docker-centos.box添加到其他vagrant环境中

　　vagrant box add first-docker-centos first-docker-centos.box

05 得到vagrantfile

　　vagrant init  first-docker-centos

06 根据vagrantfile启动虚拟机

　　vagrant up （网络可能需要从新配置）

安装docker

1.进入centos7 

vagrant ssh

2.卸载之前的docker

$ sudo yum remove docker  docker-common docker-selinux docker-engine

3.安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

4.设置yum源

$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

阿里云还可以根据账号生成镜像加速器

https://promotion.aliyun.com

1、docker添加阿里云镜像加速器
登录aliyun

2、配置阿里云加速器
阿里云会根据账号生成一个账号加速器地址，例如：
https://k9e55i4n.mirror.aliyuncs.com

将加速器地址配置到docker的daemon.json文件中：
# 编辑daemon.json
vim /etc/docker/daemon.json
# 设置加速器地址
{
  "registry-mirrors": ["https://k9e55i4n.mirror.aliyuncs.com"]
}
查看设置
cat /etc/docker/daemon.json
最后重新加载和重启docker：
systemctl daemon-reload
systemctl restart docker
下载镜像慢的话一定要设置

如果设置了阿里云的镜像加速下载一些比较大的镜像如 pxc还慢

解决办法：

1.我是默认安装的，文件是这个/etc/docker/daemon.json

直接进去修改

{ "registry-mirrors" :["https://docker.mirrors.ustc.edu.cn"]}

以下都可以替换上面的网址，个人比较喜欢科大的

国内较快的镜像原地址:

#Docker 官方中国区:https://registry.docker-cn.com

#网易 http://hub-mirror.c.163.com

#ustc中国科技大学 https://docker.mirrors.ustc.edu.cn

参考我改过的配置，下载速度哗哗的

{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn","http://hub-mirror.c.163.com"]
}

7、安装docker

$ sudo yum install docker-ce docker-ce-cli containerd.io

8、启动并加入开机启动

$ sudo systemctl start docker
$ sudo systemctl enable docker

9、查看docker是否安装成功(有client和service两部分表示docker安装启动都成功了)

$ docker version
