vagrant扩容教程
前期操作
1.找到Vagrantfile 文件所在的目录,本机所在目录为
dl@dldeMacBook-Pro Pro2 % pwd
/Users/myself/vagrant/php/machine/Pro2
dl@dldeMacBook-Pro Pro2 % ls
Vagrantfile box share2 virtual2
2.启动项目
dl@dldeMacBook-Pro Pro2 % vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
3.启动成功后会生成对应的vbox目录
dl@dldeMacBook-Pro / % cd /Users/dl/VirtualBox\ VMs/Pro2_default_1618586539591_12542 dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % pwd /Users/dl/VirtualBox VMs/Pro2_default_1618586539591_12542 dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % ls Logs Pro2_default_1618586539591_12542.vbox-prev box-disk1.vmdk Pro2_default_1618586539591_12542.vbox dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 %
4.查看当前可用空间,只有8.4G长期使用肯定不够,所以需要扩充虚拟机硬盘
[root@localhost vagrant]# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/mapper/centos-root 8.4G 1.2G 7.2G 15% /
devtmpfs 488M 0 488M 0% /dev
tmpfs 497M 0 497M 0% /dev/shm
tmpfs 497M 6.5M 491M 2% /run
tmpfs 497M 0 497M 0% /sys/fs/cgroup
/dev/sda1 497M 119M 379M 24% /boot
vagrant 224G 178G 46G 80% /vagrant
var_www_html 224G 178G 46G 80% /var/www/html
5\. 停止虚拟机,因为下面需要扩容了,需要先停止虚拟机
vagrant halt

1.开始保存 老的uuid,进入VirtualBox VMs目录，查看并记录原磁盘uuid，留作后用,其中 902de835-da8e-467e-ab01-b8e1643c6422 为现在的uuid
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage showhdinfo "box-disk1.vmdk"
UUID: 95942ed1-608b-4443-b705-429a2c73db02
Parent UUID: base
State: created
Type: normal (base)
Location: /Users/dl/VirtualBox VMs/Pro2_default_1618586539591_12542/box-disk1.vmdk
Storage format: VMDK
Format variant: dynamic default
Capacity: 10140 MBytes
Size on disk: 1591 MBytes
Encryption: disabled
In use by VMs: Pro2_default_1618586539591_12542 (UUID: f49f7c04-9386-46f3-be68-5a05de6ff23a)
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 %
2. 克隆磁盘，vmdk格式无法调整大小，需要转成vdi格式
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage clonehd ./box-disk1.vmdk new-virtualdisk.vdi --format vdi
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Clone medium created in format 'vdi'. UUID: c8bcaf5d-f4b7-407c-8c49-8f3cd3c8856f
3.# 调整克隆磁盘的大小，这里调整为200G(多了不影响,数字可以大了填写)
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage modifyhd new-virtualdisk.vdi --resize 209600
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
4.# 在克隆磁盘的基础上再克隆vdi格式的磁盘
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage clonehd new-virtualdisk.vdi resized.vmdk --format vmdk
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Clone medium created in format 'vmdk'. UUID: 992d2453-af92-4ab9-891d-ea647d330a0b
5.替换以及备份
windows:
ren box-disk1.vmdk box-disk1-backup.vmdk
ren resized.vmdk box-disk1.vmdk
linux:
mv box-disk1.vmdk box-disk1-backup.vmdk
mv resized.vmdk box-disk1.vmdk
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % mv box-disk1.vmdk box-disk1-backup.vmdk
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % mv resized.vmdk box-disk1.vmdk
6.这一步没用,主要记录命令的,不用操心
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage list vms
"Pro1_default_1548122083943_7572" {138d01ed-7f35-4e2d-a3d2-4b11382ab159}
"Pro2_default_1618586539591_12542" {f49f7c04-9386-46f3-be68-5a05de6ff23a}
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage showvminfo f49f7c04-9386-46f3-be68-5a05de6ff23a
Name: Pro2_default_1618586539591_12542
Groups: /
Guest OS: Red Hat (64-bit)
UUID: f49f7c04-9386-46f3-be68-5a05de6ff23a
Config file: /Users/dl/VirtualBox VMs/Pro2_default_1618586539591_12542/Pro2_default_1618586539591_12542.vbox
Snapshot folder: /Users/dl/VirtualBox VMs/Pro2_default_1618586539591_12542/Snapshots
Log folder: /Users/dl/VirtualBox VMs/Pro2_default_1618586539591_12542/Logs
7. !!!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
dl@dldeMacBook-Pro Pro2_default_1618586539591_12542 % vboxmanage internalcommands sethduuid box-disk1.vmdk 95942ed1-608b-4443-b705-429a2c73db02
UUID changed to: 95942ed1-608b-4443-b705-429a2c73db02
8 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
正式扩容
1.进入虚拟机
vagrant reload #重新开启虚拟机
vagrant ssh # 进入虚拟机
2.查看磁盘详情
[root@localhost vagrant]# fdisk -l
磁盘 /dev/sda：219.8 GB, 219781529600 字节，429260800 个扇区
Units = 扇区 of 1 * 512 = 512 bytes

3.操作下面的,一定要按照下面的步骤操作,其中 t 3 8e 很重要
fdisk /dev/sda
按p显示分区表，默认是 sda1 和 sda2。
按n新建主分区。
按p设置为主分区。
输入3设置为第三分区。
输入一次回车设置默认磁盘位置。
再输入一次回车设置默认磁盘位置。
输入t改变分区格式
输入3选择第三分区
输入8e格式成LVM格式
输入w执行保存
4.创建物理卷
[root@localhost vagrant]# pvcreate /dev/sda3
Physical volume "/dev/sda3" successfully created5.显示物理卷属,并找到物理卷的名字
[root@localhost vagrant]# pvdisplay | grep "VG Name"
VG Name centos VG Name6.显示所有卷组的属性
[root@localhost vagrant]# vgdisplay
--- Volume group --- VG Name centos System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 3 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 9.41 GiB PE Size 4.00 MiB Total PE 2409 Alloc PE / Size 2399 / 9.37 GiB Free PE / Size 10 / 40.00 MiB VG UUID NJWfOH-An0K-Hm9Q-8Tjs-yq2x-ZWXi-L2vP7i 7.使用vgextend命令可以动态扩展卷组，它通过向卷组中添加物理卷来增加卷组的容量。
[root@localhost vagrant]# vgextend centos /dev/sda3
Volume group "centos" successfully extended 8.查看文件系统的名字 为 /dev/mapper/centos-root
[root@localhost vagrant]# df -h
文件系统 容量 已用 可用 已用% 挂载点
/dev/mapper/centos-root 8.4G 1.2G 7.2G 15% /
devtmpfs 488M 0 488M 0% /dev
tmpfs 497M 0 497M 0% /dev/shm

vagrant 224G 178G 46G 80% /vagrant
var_www_html 224G 178G 46G 80% /var/www/html
9.扩展逻辑卷 lvextend指令用于在线扩展逻辑卷的空间大小，而不中断应用程序对逻辑卷的访问。
[root@localhost vagrant]# lvextend /dev/mapper/centos-root /dev/sda3
Size of logical volume centos/root changed from 8.38 GiB (2145 extents) to 203.16 GiB (52009 extents). Logical volume root successfully resized
10.同步文件系统
[root@localhost vagrant]# xfs_growfs /dev/mapper/centos-root
meta-data=/dev/mapper/centos-root isize=256 agcount=4, agsize=549120 blks
= sectsz=512 attr=2, projid32bit=1 = crc=0 finobt=0data = bsize=4096 blocks=2196480, imaxpct=25

= sectsz=512 sunit=0 blks, lazy-count=1realtime =none extsz=4096 blocks=0, rtextents=0
data blocks changed from 2196480 to 53257216
11.重启虚拟机
[root@localhost vagrant]# reboot
Connection to 127.0.0.1 closed by remote host.
Connection to 127.0.0.1 closed.
12.重启并校验
dl@dldeMacBook-Pro Pro2 % vagrant reload
==> default: Attempting graceful shutdown of VM...
dl@dldeMacBook-Pro Pro2 % vagrant ssh
