# 编辑sources.list
nano /etc/apt/sources.list
# 将原有的源链接在句首加 # 注释掉，更换以下清华源信息
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm main contrib non-free non-free-firmware
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bookworm-updates main contrib non-free non-free-firmware

deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bookworm-security main contrib non-free non-free-firmware

2）PVE更换企业源

# 编辑pve-enterprise.list
nano /etc/apt/sources.list.d/pve-enterprise.list
# 将原有的源链接在句首加 # 注释掉，更换以下清华源信息
deb https://mirrors.tuna.tsinghua.edu.cn/proxmox/debian bookworm pve-no-subscription

3）修复更新源时报401错误

# 编辑ceph.list
nano /etc/apt/sources.list.d/ceph.list
# 将原有的源链接在句首加 # 注释掉，添加中科大ceph源
deb https://mirrors.ustc.edu.cn/proxmox/debian/ceph-quincy bookworm no-subscription
# 执行更新
apt update

4）LXC容器更换源

# 备份APLInfo.pm
cp /usr/share/perl5/PVE/APLInfo.pm /usr/share/perl5/PVE/APLInfo.pm_back
# 替换为清华源：
sed -i 's|http://download.proxmox.com|https://mirrors.tuna.tsinghua.edu.cn/proxmox|g' /usr/share/perl5/PVE/APLInfo.pm
# 重启服务后生效
systemctl restart pvedaemon.service

5）删除local-lvm将空间合并到local

# 使用命令删除local-lvm
lvremove /dev/pve/data
# 输入y，确认，输出以下信息即成功
Do you really want to remove active logical volume pve/data? [y/n]: y
  Logical volume "data" successfully removed.
# 再将local-lvm的空间转移到pve-root
lvextend -rl +100%FREE /dev/pve/root
# 输出以下信息即合并local分区成功
Size of logical volume pve/root changed from <9.75 GiB (2495 extents) to <19.50 GiB (4991 extents).
  Logical volume pve/root successfully resized.
resize2fs 1.47.0 (5-Feb-2023)
Filesystem at /dev/mapper/pve-root is mounted on /; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 3
The filesystem on /dev/mapper/pve-root is now 5110784 (4k) blocks long.

删除了lvm-thin之后，还需要在Web删除local-lvm才算完成。

6）禁止PVE修改网卡名称, 使用 ethX 命名
使用nano命令编辑/etc/default/grub在GRUB_CMDLINE_LINUX=""加入这个参数即可net.ifnames=0 biosdevname=0

# 更新GRUB
update-grub

7）将PVE设置成DHCP方式获取IP
使用nano命令编辑nano /etc/network/interfaces将里面的内容全部删除，替换以下信息，重启生效

auto lo
iface lo inet loopback

iface eth0 inet manual

auto vmbr0
iface vmbr0 inet dhcp
        bridge-ports eth0
        bridge-stp off
        bridge-fd 0


source /etc/network/interfaces.d/*

改为DHCP方式后，PVE的管理地址将会由路由设备随机分配一个IP给PVE。需要登录到PVE输入ip -c a查看实际获取到的IP。

8）将DHCP获取到的IP输入到控制台显示
前面说了控制台显示的IP是写死静态的，那么我们让其能正常输出正确IP。

使用nano命令编辑nano /usr/bin/pvebanner将里面的内容全部删除，替换以下信息，重启生效

#!/usr/bin/perl
sleep(8);
$ip .= `hostname -I`;

$banner = <<__EOBANNER;

__EOBANNER

print "$ip";


open(ISSUE, ">/etc/issue");
print ISSUE $banner;
close(ISSUE);
exit (0);

重启PVE后，控制台就可以返回DHCP所获取到的正确IP了。
