Upgrade PMM Client¶
There are two primary methods to update PMM Clients, depending on your initial installation method:
- Using your operating system’s package manager.
- Updating from a tarball.
1. Package Manager method¶
The package manager method is generally more convenient and efficient. Percona provides the percona-release package, which helps you install Percona software, including the PMM Client. The PMM Client is available from the pmm-client repository.
To deploy a new version of the Client via package manager, simply replace the currently installed package with the latest version of the PMM Client or with a specific version.
Install the latest PMM Client version¶
Run the commands below to install the latest PMM Client version via package manager and keep your existing Client configuration during the update process.
For example, to install the latest version of the PMM Client on Red Hat or its derivatives:
percona-release enable pmm-client
yum update pmm-client
Deploy a specific version¶
To deploy a specific version of the PMM Client via package manager, check the available versions and then provide the full name of the package. For example:
```sh
yum --showduplicates search pmm-client
pmm-client-3.0.0-6.el9.x86_64 : Percona Monitoring and Management Client (pmm-agent)
pmm-client-3.0.1-6.el9.x86_64 : Percona Monitoring and Management Client (pmm-agent)
yum update pmm-client-3.0.1-6.el9.x86_64
```
2. Tarball method¶
If you initially installed the PMM Client from a tarball, you can update it by replacing the currently installed package with the latest version:
- Download
tar.gzwithpmm-client. - Extract the tarball.
- Run
./install_tarballscript with the-uflag.
Important
The configuration file will be overwritten if you do not provide the -u flag while the pmm-agent is updated.
