PVE LXC安裝PNETLAB

PVE內安裝PNETLAB可建立VM正常安裝，但是虛擬機在PVE裡經過多層虛擬化效能不佳，故使用CT安裝來接近本機效能

運行環境

• PVE 7
• LXC ubuntu-18.04

PVE設定

確認PVE已安裝openvswitch-switch

systemctl status openvswitch-switch

若未安裝執行

apt update
apt install openvswitch-switch

 

 

建立CT

取消勾選無特權容器，範本選擇ubuntu-18.04，建立容器後選擇不開機

進入PVE SHELL修改LXC設定，編輯/etc/pve/lxc/<lxc-id>.conf，新增以下設定後啟動CT

features: nesting=1
lxc.cgroup2.devices.allow: c 10:200 rwm
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file
lxc.cgroup2.devices.allow: c 10:232 rwm
lxc.mount.entry: /dev/kvm dev/kvm none bind,create=file

安裝PNETLAB

PVE網頁上開啟CT視窗，修改允許root SSH登入

sed -i -e "s/.*PermitRootLogin .*/PermitRootLogin yes/" /etc/ssh/sshd_config

service sshd restart

重新登入PNETLAB，編輯/etc/apt/sources.list新增repository

deb [trusted=yes] http://repo.pnetlab.com ./

開始安裝

echo "nameserver 8.8.8.8" > /etc/resolv.conf
apt-get update
apt-get purge netplan.io
apt-get install pnetlab -y

安裝到這裡時會卡住，因為PNETLAB和CT網路設定會衝突

To activate the new configuration, you need to run:
  systemctl restart apache2
Considering dependency proxy for proxy_html:
Enabling module proxy.
Considering dependency xml2enc for proxy_html:
Enabling module xml2enc.
Enabling module proxy_html.
To activate the new configuration, you need to run:
  systemctl restart apache2

將CT的網路設定靜態並移除IP後重啟CT

重新登入PNETLAB後開始初始化安裝，完成後會再次重啟

重啟後確認可進入PNETLAB網頁

若出現file_get_contents訊息

file_get_contents(http://127.0.0.1/html5/api/tokens): failed to open stream: HTTP request failed! HTTP/1.1 5XX Service Unavailable

於PNETLAB內修正

sed -i '/skip_ssl/d' /etc/mysql/mysql.conf.d/mysqld.cnf
echo "skip_ssl" >> /etc/mysql/mysql.conf.d/mysqld.cnf
service mysql restart

qemu啟動需安裝net-tools

apt install net-tools

測試虛擬機

測試建立的虛擬機可正常執行

若啟動失敗，觀察詳細報錯紀錄
