下载

下载url ,然后选择Proxmox VE 5.x ISO Installer

https://www.proxmox.com/en/downloads/item/proxmox-ve-5-1-iso-installer

下载完成后 和官网 SHA256SUMS 对比一下 用下面的命令

evan@evanpc:~/iso/proxmox$ sha256sum  proxmox-ve_5.1-722cc488-1.iso 
e279547f07402cae615834cc7ea1cebd1ec05028e892e93c2327d0bc049fc914  proxmox-ve_5.1-722cc488-1.iso

使用

一些要注意的

1)写入U盘得用 dd才行
dd if=pve-cd.iso of=/dev/XYZ bs=1M
http://pve.proxmox.com/wiki/Install_from_USB_Stick 


proxmox 上传镜像
在create vm时可以不用物理光驱,此处是proxmox的母机
/var/lib/vz/template/iso

vm 安装centos7

来不及设置密码 启动机器后 单用户进去就行了

Centos7单用户模式

win user

win32 disk imager 推荐这个写入

usb

我是直接在web界面添加然后添加你穿入的USB

硬件--> 添加--> usb设备--> 使用usb端口--> --> -->

proxmox VE 4.4 增加USB 重定向功能

修改Proxmox VE 5的储存方式，不使用 lvmthin


修改Proxmox VE 5的储存方式，不使用 lvmthin

Proxmox VE 5 使用的是lvmthin这种方式来存放vm的磁盘镜像文件，据Proxmox的说明文档中所述，这种方式是block型的存储，速度会更快，而且是按实际使情况来分配空间，所以可以分配出看上去比实际要大的空间出来（存在一定风险），让终端用户看起来有很多空间，总之好处很多。
但对于单位内部来说，我觉得不必去节省这些存在风险的成本，而且我还有不少的KVM旧文件需要迁到这里来，用这种存储方式不太方便。所以将这种方式改为传统方式。以下是在新安装没有创建任何VM或CT的前提下操作。

一、修改storage配置文件

cd /etc/pve/
cp storage.cfg storage.cfg.1

nano storage.cfg
将文件从
--------------
dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

lvmthin: local-lvm
        thinpool data
        vgname pve
        content rootdir,images
------------
注：vgname pve (这个是vg名，在/dev目录下可找到，可使用 pvs, vgs, lvs等命令查看)

改为：
---------------------
dir: local
        path /var/lib/vz
        content rootdir,content iso,images,vztmpl,backup
--------------------

二、将 lvmthin 变回传统文件系统格式，并挂载。

mkfs.ext4 /dev/pve/data
mount /dev/pve/data /mnt
cp -r /var/lib/vz/* /mnt
mount /dev/pve/data /var/lib/vz/

三、修改fstab
nano /etc/fstab
--------------------
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext4 errors=remount-ro 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
/dev/pve/data /var/lib/vz/ ext4 defaults 0 0

修改Proxmox VE 5的储存方式，不使用 lvmthin

Proxmox 删除local-lvm 操作步骤

ProXmoX VE升级

vim /etc/apt/sources.list.d/pve-enterprise.list
#deb https://enterprise.proxmox.com/debian/pve stretch pve-enterprise
#也可以直接删除掉
rm -f /etc/apt/sources.list.d/pve-enterprise.list

#5
echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list

wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

#5 to 6

echo "deb http://download.proxmox.com/debian/pve buster pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
sed -i 's/stretch/buster/g' /etc/apt/sources.list

apt update
apt dist-upgrade

#6 to  7
Update the configured APT repositories

First, make sure that the system is using the latest Proxmox VE 6.4 packages:

apt update
apt dist-upgrade

Update all Debian repository entries to Bullseye.

sed -i 's/buster\/updates/bullseye-security/g;s/buster/bullseye/g' /etc/apt/sources.list

#也可直接换成国内的源 
vi /etc/apt/sources.list

deb https://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye main non-free contrib
deb https://mirrors.aliyun.com/debian-security/ bullseye-security main
deb-src https://mirrors.aliyun.com/debian-security/ bullseye-security main
deb https://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye-updates main non-free contrib
deb https://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib
deb-src https://mirrors.aliyun.com/debian/ bullseye-backports main non-free contrib


#Add the Proxmox VE 7 Package Repository

echo "deb https://enterprise.proxmox.com/debian/pve bullseye pve-enterprise" > /etc/apt/sources.list.d/pve-enterprise.list
sed -i -e 's/buster/bullseye/g' /etc/apt/sources.list.d/pve-install-repo.list 

#Upgrade the system to Debian Bullseye and Proxmox VE 7.0
apt update && apt dist-upgrade

升级完成后，可以执行pveversion -v查看下最新的软件版本。然后执行reboot重启物理服务器

trouble shooting

1.在 dell 服务器上安装出错

command 'chroot /target dpkg --force-confold --configure -a' failed with exit code 1 at /usr/bin/proxinstall line 385

原来raid 没有初始化

2. TASK ERROR: Failed to run vncproxy.

可能是没打开虚拟化

3 升级问题

 
 If you are unsure why 'proxmox-ve' would be removed, please verify
W: (pve-apt-hook) 	- your APT repository settings
W: (pve-apt-hook) 	- that you are using 'apt full-upgrade' to upgrade your system
E: Sub-process /usr/share/proxmox-ve/pve-apt-hook returned an error code (1)
E: Failure running script /usr/share/proxmox-ve/pve-apt-hook
root@pve:~# /etc/apt/sources.list.d/pve-install-repo.list^C

-bash: etc/apt/sources.list.d/pve-install-repo.list: No such file or directory
root@pve:~# cat /etc/apt/sources.list.d/pve-install-repo.list
#deb http://download.proxmox.com/debian/pve stretch pve-no-subscription
deb http://download.proxmox.com/debian/pve buster pve-no-subscription
root@pve:~# sed -i -e 's/buster/bullseye/g' /etc/apt/sources.list.d/pve-install-repo.list 



少了一步 
 sed -i -e 's/buster/bullseye/g' /etc/apt/sources.list.d/pve-install-repo.list

clone出来的VM启动不了 
Proxmox trying to acquire lock... TASK ERROR: can't lock file '/var/lock/qemu-server/lock-102.conf' - got timeout

If Proxmox won't start aVM with an error like this:

trying to acquire lock...
TASK ERROR: can't lock file '/var/lock/qemu-server/lock-102.conf' - got timeout

rm /var/lock/qemu-server/lock-102.conf

Then try to restart the VM and it should be good.
