Create a local mirror of a Percona repository¶

Enterprises introduce various security policies: for example, allow Internet access only on one server or deny root privileges to database administrators.

To comply with these policies and install Percona software in your environment, a solution is to set up the local mirror of Percona repositories. This document provides instructions how to do it.

Important

The instructions below are for AMD/Intel x64 architectures.

Prerequisites¶

To create a local mirror of a Percona repository, you need the following software:

Rsync to download packages from Percona repositories and upload them to your mirror
Repository creation tools:
- dpkg-dev for Debian and Ubuntu
- createrepo for RHEL and derivatives

Debian and Ubuntu¶

Run the following commands as the root user or via sudo:

Install dpkg-dev utility to unpack, build and upload Debian source packages.
```
$ sudo apt install dpkg-dev
```
Create the folder where your mirror repository resides. For example, /opt/debs/
```
$ sudo mkdir -p /opt/debs/
```
Download the .deb packages relevant to your operating system from Percona repository into your repository using rsync:
```
$ sudo rsync -avrt rsync://rsync.percona.com/rsync/<repo-name>/apt/pool/main/p/<product_name>/*.<os-version>*.deb /opt/debs/
```
For example, to download Percona Backup for MongoDB packages on Ubuntu 22.04, the command is the following:
```
$ sudo rsync -avrt rsync://rsync.percona.com/rsync/pbm/apt/pool/main/p/percona-backup-mongodb/*.jammy*.deb /opt/debs/
```
Check the list of available repositories for MySQL, MongoDB, PostgreSQL and Percona Tools.
Create the Packages file. This is the file that the package manager uses to retrieve the information about new and updated packages when you run apt-get update. Use the dpkg-scanpackages command:
```
$ cd /opt/debs
$ sudo dpkg-scanpackages . /dev/null > Packages
```
The command adds the latest version of the packages to the Packages file.

Import the GPG key to sign the repository.

$ sudo curl -fsSL https://github.com/percona/percona-repositories/raw/main/deb/percona-keyring.gpg | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/percona-keyring.gpg >/dev/null

Add your repository to the etc/apt/sources.list file for the package manager to find new or updated packages from your repository:
```
$ echo "deb [trusted=yes] file:///opt/debs ./" | sudo tee -a /etc/apt/sources.list
```
Run apt-get update to check that the package manager can read from your repository.

(Optional) Check your mirror repository contents:

$ sudo apt-cache policy percona-backup-mongodb

Sample output

percona-backup-mongodb: 
 Installed: (none) 
 Candidate: 2.3.1-1.jammy 
 Version table: 
    2.3.1-1.jammy 500 
       500 file:/opt/debs ./ Packages

RHEL and derivatives¶

Run the following commands as the root user or via sudo:

Install the createrepo utility. It creates yum repositories and their metadata caches
```
$ sudo yum install createrepo
```
Create the directory where your mirror repository resides. For example, /opt/rpms
```
$ sudo mkdir /opt/rpms
```
Download RPM packages from Percona repository to your local mirror using rsync:
```
$ sudo rsync -avrt rsync://rsync.percona.com/rsync/<repo_name>/yum/release/<os_version>/RPMS/x86_64/ /opt/rpms/
```
For example, to download packages for Percona Distribution for PostgreSQL 15 on Oracle Linux 9, the command is the following:
```
$ sudo rsync -avrt rsync://rsync.percona.com/rsync/ppg-15/yum/release/9/RPMS/x86_64/ /opt/rpms/
```
Check the list of available repositories for MySQL, MongoDB, PostgreSQL and Percona Tools.
Create the repository metadata using createrepo:
```
$ sudo createrepo --update /opt/rpms
```

Import the GPG key to sign the repository:

$ sudo rpm --import https://raw.githubusercontent.com/percona/percona-repositories/release-1.0-27/rpm/RPM-GPG-KEY-Percona

Check that the key has been imported successfully:

$ sudo rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'

Sample output

gpg-pubkey-8507efa5-5b02c2fb    gpg(Percona MySQL Development Team (Packaging key) <mysql-dev@percona.com>)

Create the repository configuration file. It must meet the following criteria:
- It must be located in /etc/yum.repos.d/
- It must have the extension .repo to be recognized by yum.
The following is the example of the configuration file:
/etc/yum.repos.d/percona-local.repo
```
[percona-local]
name=Local Percona repository
baseurl=file:///opt/rpms/
gpgcheck=1
enabled=1
```

Check the setup:

$ sudo yum repolist

Sample output

percona-local                       Local Percona repository

Keep the mirror repository up-to-date¶

To update your local mirror, do the following:

Debian and UbuntuRHEL and derivatives

Download new packages relevant to your operating system from Percona repository

$ rsync -avrt rsync://rsync.percona.com/rsync/<repo-name>/apt/pool/main/p/<product_name>/*.<os-version>*.deb /opt/debs/

Update the Packages file.

$ cd /opt/debs
dpkg-scanpackages . /dev/null > Packages

Update the local cache.
```
$ apt update
```

Download new packages from Percona repository

$ rsync -avrt rsync://rsync.percona.com/rsync/<repo_name>/yum/release/<os_version>/RPMS/x86_64/ /opt/rpms/

Update the repository metadata
```
$ sudo createrepo --update /opt/rpms
```

Tip

You can automate the download process by adding the task to crontab.
