MySQL replication is a process that enables data from one MySQL database server (the master) to be copied automatically to one or more MySQL database servers (the slaves). Replication is asynchronous by default. Slaves do not need to be connected permanently to receive updates from the master. Depending on the configuration, you can replicate all databases, selected databases, or even selected tables within a database.

If you want to replace the certificate for your hostname with a custom certificate but you had enabled Let’s Encrypt, you will need to disable Let’s Encrypt for the hostname first. The following command let’s DirectAdmin know that it does not need to renew the Let’s Encrypt certificate. This is required as DirectAdmin will renew the certificate +/- 60 days after the last renewal, even when the Let’s Encrypt certificate is not installed.
rm -rf /usr/local/directadmin/data/users/user_name/domains/domain_name.lt.san_config rm -rf /usr/local/directadmin/data/users/user_name/domains/domain_name.lt.cert.creation_time
LVM, or Logical Volume Management, is a storage device management technology that gives users the power to pool and abstract the physical layout of component storage devices for easier and flexible administration. Utilizing the device mapper Linux kernel framework, the current iteration, LVM2, can be used to gather existing storage devices into groups and allocate logical units from the combined space as needed.

Proxmox VE 5.4 has been released, this version is based on Debian 9. (Linux Kernel 4.15) It includes allot of new features, but sadly updates are still pointing to the enterprise repository for updates. This results in ugly error message when trying
apt-get update
such as:
[email protected]:~# apt-get update Hit:1 http://security.debian.org stretch/updates InRelease Ign:2 http://ftp.debian.org/debian stretch InRelease Hit:3 http://ftp.debian.org/debian stretch-updates InRelease Hit:4 http://ftp.debian.org/debian stretch Release Ign:5 https://enterprise.proxmox.com/debian/pve stretch InRelease Ign:6 https://enterprise.proxmox.com/debian/pve stretch Release Ign:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Ign:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Ign:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Ign:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Ign:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Err:7 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise amd64 Packages 401 Unauthorized Ign:8 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise all Packages Ign:10 https://enterprise.proxmox.com/debian/pve stretch/pve-enterprise Translation-en Reading package lists... Done W: The repository 'https://enterprise.proxmox.com/debian/pve stretch Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch https://enterprise.proxmox.com/debian/pve/dists/stretch/pve-enterprise/binary-amd64/Packages 401 Unauthorized E: Some index files failed to download. They have been ignored, or old ones used instead.
To fix this, its similar to V3.X and V4.X. We need to add one repository:
nano /etc/apt/sources.list
add:
deb http://download.proxmox.com/debian stretch pve-no-subscription
Then disable or remove
rm -f /etc/apt/sources.list.d/pve-enterprise.list
(for disable add a # in front of the first line starting with deb)
Now you can run those updates take note only
apt-get update
and
apt-get dist-upgrade
are supported by Proxmox!
