Upgrade using standalone packages

Make a full backup (or dump if possible) of your database. Move the database configuration file, my.cnf, to another direction to save it. Stop the server with /etc/init.d/mysql stop.

Debian-derived distributionRed Hat-derived distributions

1. Remove the installed packages with their dependencies: sudo apt autoremove percona-server percona-client

2. Do the required modifications in the database configuration file my.cnf.

3. Download the following packages for your architecture:

   • percona-server-server

   • percona-server-client

   • percona-server-common

   • libperconaserverclient21

   The following example downloads Percona Server for MySQL 8.4.3-3 packages for Debian 11.0:

   $ wget https://downloads.percona.com/downloads/Percona-Server-innovative-release/Percona-Server-8.4.3-3/binary/debian/bullseye/x86_64/Percona-Server-8.4.3-3-r582ebeef-bullseye-x86_64-bundle.tar
   

4. Unpack the bundle to get the packages: tar xvf Percona-Server-8.4.3-3-x86_64-bundle.tar.

   After you unpack the bundle, you should see the following packages:

   $ ls *.deb
   

   Expected output

   llibperconaserverclient21-dev_8.4.3-3.bullseye_amd64.deb  
   percona-server-dbg_8.4.3-3.bullseye_amd64.deb
   libperconaserverclient21_8.4.3-3.bullseye_amd64.deb      
   percona-server-rocksdb_8.4.3-3.bullseye_amd64.deb
   percona-mysql-router_8.4.3-3.bullseye_amd64.deb
   percona-server-server_8.4.3-3.bullseye_amd64.deb
   percona-server-client_8.4.3-3.bullseye_amd64.deb     
   percona-server-source_8.4.3-3.bullseye_amd64.deb
   percona-server-common_8.4.3-3.bullseye_amd64.deb     
   percona-server-test_8.4.3-3.bullseye_amd64.deb
   

5. Install Percona Server for MySQL:

   $ sudo dpkg -i *.deb
   

   This command installs the packages from the bundle. Another option is to download or specify only the packages you need for running Percona Server for MySQL installation (libperconaserverclient21-dev_8.4.3-3.bullseye_amd64.deb, percona-server-client-8.4.3-3.bullseye_amd64.deb, percona-server-common-8.4.3-3.bullseye_amd64.deb, and percona-server-server-8.4.3-3.bullseye_amd64.deb.

   Warning

   When installing packages manually, you must resolve all the dependencies and install missing packages yourself. At least the following packages should be installed before installing Percona Server for MySQL 8.4.3-3: * libmecab2, * libjemalloc1, * zlib1g-dev, * libaio1.

6. Running the upgrade:

   The mysqld binary automatically runs the upgrade process. To find more information, see MySQL Upgrade Process Upgrades

7. Restart the service with service mysql restart. After the service has been successfully restarted use the new Percona Server for MySQL 8.4.3-3.

1. Check the installed packages:

   $ rpm -qa | grep percona-server
   

   Expected output

   percona-server-shared-8.4.3-3.el9.x86_64
   percona-server-shared-compat-8.4.3-3.el9.x86_64
   percona-server-client-8.4.3-3.el9.x86_64
   percona-server-server-8.4.3-3.el9.x86_64
   

   You may have the shared-compat package, which is required for compatibility.

2. Remove the packages without dependencies with rpm -qa | grep percona-server | xargs rpm -e --nodeps.

   It is important that you remove the packages without dependencies as many packages may depend on these (as they replace mysql) and will be removed if omitted.

   To remove the listed packages, run:

   $ rpm -qa | grep '^mysql-'| xargs rpm -e --nodeps`
   

3. Download the packages of the desired series for your architecture from the download page. The easiest way is to download the bundle which contains all the packages. The following example downloads Percona Server for MySQL 8.4.3-3 packages for CentOS 9:

   $ wget https://downloads.percona.com/downloads/Percona-Server-innovative-release/Percona-Server-8.4.3-3/binary/redhat/9/x86_64/Percona-Server-8.4.3-3-r582ebeef-el9-x86_64-bundle.tar
   

4. Unpack the bundle to get the packages

   $ tar xvf Percona-Server-8.4.3-3-r582ebeef-el9-x86_64-bundle.tar
   

   After you unpack the bundle, you should see the following packages: ls \*.rpm

5. Install Percona Server for MySQL:

   $ sudo rpm -ivh percona-server-server-8.4.3-3.el9.x86_64.rpm \
   > percona-server-client-8.4.3-3.el9.x86_64.rpm \
   > percona-server-shared-8.4.3-3.el9.x86_64.rpm \
   > percona-server-shared-compat-8.4.3-3.el9.x86_64.rpm
   

   This command installs only packages required to run the Percona Server for MySQL 8.4.3-3.

6. You can install all the packages (for debugging, testing, etc.) with sudo rpm -ivh \*.rpm.

   Note

   When manually installing packages, you must resolve all the dependencies and install missing ones.

7. Modify your configuration file, my.cnf, and install the plugins if necessary.

RHEL/CentOS automatically backs up the previous configuration file to /etc/my.cnf.rpmsave and installs the default my.cnf. After the upgrade/install process completes you can move the old configuration file back (after you remove all the unsupported system variables).

1. The schema of the grant table has changed, the server must be started without reading the grants. Add a line to my.cnf in the [mysqld] section,

[mysqld]
skip-grant-tables

Restart the mysql server with service mysql start.

1. Running the upgrade:

   The mysqld binary automatically runs the upgrade process. To find more information, see MySQL Upgrade Process Upgrades

2. Restart the server with service mysql restart. After the service has been successfully restarted you can use the new Percona Server for MySQL 8.4.3-3.
