proxmox更改登陆banner

修改pve banner 参考http://blog.jason.tools/2019/05/proxmox-ve-ip-banner.html

/etc/systemd/system/getty.target.wants/pvebanner.service 内容如下：
[Unit]
Description=Proxmox VE Login Banner
ConditionPathExists=/usr/bin/pvebanner
DefaultDependencies=no
After=local-fs.target
Before=console-getty.service

[Service]
ExecStart=/usr/bin/pvebanner
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=getty.target

/usr/bin/pvebanner内容如下：

#!/usr/bin/perl

use strict;
use PVE::INotify;
use PVE::Cluster;

my $nodename = PVE::INotify::nodename();
my $localip = PVE::Cluster::remote_node_ip($nodename, 1);

my $xline = '-' x 78;

my $banner = '';

if ($localip) {
    $banner .= <<__EOBANNER;

$xline

Welcome to the Proxmox Virtual Environment. Please use your web browser to
configure this server - connect to:

  https://${localip}:8006/

$xline

__EOBANNER

}

open(ISSUE, ">/etc/issue");

print ISSUE $banner;

close(ISSUE);

exit (0);

首先 cp /usr/bin/pvebanner /usr/bin/pvebanner.bak
然后修改下面这段内容

Welcome to the Proxmox Virtual Environment. Please use your web browser to
configure this server - connect to:

  https://${localip}:8006/

修改完毕后，需要systemctl restart pvebanner 然后exit console既可以立即看到效果， 推荐将 https://${localip}:8006/ 行去掉避免被看到访问的入口。
