使用Vagrant快速创建虚拟机

1
vagrant init centos/7
1
2
vagrant up
vagrant up --provider=vmware_desktop

若提示找不到provider则需要安装对应的utility：

列如：这里的provider是VMware，参考步骤:

  1. 安装Download Vagrant VMWare Utility
  2. 运行vagrant plugin install vagrant-vmware-desktop或vagrant plugin install vagrant-vmware-workstation

如果还是搞不好的话就还是用Vagrant默认支持的VirtualBox吧Download

如果出现如下下载慢的情况的话可以使用链接手动下载然后导入：

先查看本地安装的box：

1
vagrant box list

再将得到的box文件手动添加进去：

1
vagrant box add --name centos/7 D:\VirtualMachine_centerOS7\virtualbox.box

添加完之后再run一下命令vagrant up：

当虚拟机安装完成之后会自动启动，启动完成会出现以下提示：

使用ssh连接虚拟机：

1
vagrant ssh

查看当前用户：whoami

退出ssh连接：exit;

端口转发

可以直接在VirtualBox设置->网络->连接方式：网络地址转换(NAT)->端口转发 里面设置

也可通过修改Vagrantfile配置文件来改

通过修改Vagrantfile配置文件来配置虚拟机IP

可以看到IP地址已经是192.168.33.10了

ping 192.168.33.10
ping 192.168.2.148

测试一下都可以ping通即可

配置Docker

安装docker engine

Install Docker Engine on CentOS

按照官方文档配即可，不再赘述

设置Docker开机自启动

[vagrant@localhost ~]$ sudo systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

配置镜像加速

登录阿里云，然后访问容器镜像服务->镜像中心->镜像加速器

eg: https://sb0h74rp.mirror.aliyuncs.com

}

sudo systemctl daemon-reload
sudo systemctl restart docker

-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/var/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7

sudo docker ps

-p表示端口映射

-v挂载docker容器内部目录到外部目录

-d表示后台运行

进入mysql容器内部

1
sudo docker exec -it mysql /bin/bash

-d redis redis-server /etc/redis/redis.conf

docker start c24743e3c322
docker rm -f c24743e3c322

-d后面的是启动额外命令，表示以该配置文件启动
