Vagrant Tips

共享目录

问题

共享文件夹失效, 提示：

Vagrant was unable to mount VirtualBox shared folders. This is usually

because the filesystem “vboxsf” is not available. This filesystem is

made available via the VirtualBox Guest Additions and kernel module.

Please verify that these guest additions are properly installed in the

guest. This is not a bug in Vagrant and is usually caused by a faulty

Vagrant box.

解决

1	vagrant plugin install vagrant-vbguest

磁盘扩容

# 停止虚拟机
vagrant halt <machine_name>

# 进入VirtualBox VMs目录，查看并记录原磁盘uuid，留作后用
vboxmanage showhdinfo box-disk1.vmdk

# 克隆磁盘，vmdk格式无法调整大小，需要转成vdi格式
vboxmanage clonehd box-disk1.vmdk new-virtualdisk.vdi --format vdi

# 调整克隆磁盘的大小，这里调整为400G
vboxmanage modifyhd new-virtualdisk.vdi --resize 409600

# 在克隆磁盘的基础上再克隆vdi格式的磁盘
vboxmanage clonehd new-virtualdisk.vdi resized.vmdk --format vmdk

# 覆盖原磁盘（如果担心磁盘数据出现不可逆损坏，请先做好备份）
mv resized.vmdk box-disk1.vmdk

# 此时节已删除中间文件
rm new-virtualdisk.vdi

# !!!此时启动虚机或查看磁盘信息会报错，提示uuid不匹配，因为磁盘已经变了，需要改回之前记录的uuid
vboxmanage internalcommands sethduuid box-disk1.vmdk <old_uuid>

# done，可以重启虚机了，可根据需要在虚机上进行磁盘分配，这里不再展开
vagrant up <machine_name>

Docker运行权限设置

1. sudo groupadd docker # 一般安装docker后已经创建
2. sudo gpasswd -a vagrant docker # 用户vagrant加入docker组
3. sudo service docker restart # 重启docker
4. exit -> vagrant ssh # 退出 & 重新进入

SSH免密登录Permission denied

# Log in as root
# Edit ssh config: 
sudo vim /etc/ssh/sshd_config

# Change this line:
# PasswordAuthentication no
# to
# PasswordAuthentication yes

# Restart daemon: 
sudo systemctl restart sshd

# Do ssh-copy-id:
ssh-copy-id someuser@<my-ip>

Vagrant ssh使用本机私钥

# 启动虚机 & ssh 进入虚机 
vagrant up (—provision)

#	生成密钥对
ssh-keygen -t rsa 

#	本地主机拷贝公钥到虚机 ~/.ssh/authorized_keys
ssh-copy-id -i ~/.ssh/id_rsa.pub vagrant@虚机

# 停止虚机
 vagrant halt
 
# 修改配置 
sudo vim Vagrantfile

# Add code
Vagrant.configure("2") do |config|
  config.ssh.private_key_path = "~/.ssh/id_rsa"
  config.ssh.forward_agent = true
end

# 重启 & vagrant ssh
vagrant up & vagrant ssh
