This page explains how to update Piwik to the latest version. We hope you will always use the latest version of Piwik and have made upgrading a very easy and safe process. There are two main methods:
The One-Click Piwik Update
You can use the one-click upgrade and update your Piwik in 10 seconds – in just one click of a button!
Step 1: Set Write Permissions on the Piwik folder with FTP
To carry out the one-click update, the Piwik folder needs to have the correct permissions on your web server, to allow Piwik to download the file, extract Piwik and overwrite the existing files.
Please give write permission via your FTP software (CHMOD 0755) to your piwik root folder. In some cases, the auto update might still not work, try to change the owner of the piwik to your web server user, or temporarily CHMOD 0777.
After the one click update has successfully completed, you may also choose to change back your Piwik folder and files to read only permissions (except the tmp/ folder which must be writable at all times).
Click on the Alert Box in Piwik
When you use Piwik, the info box looks like this:
When a new version of Piwik is available, you’ll be alerted in this box.
Once a new Piwik version is released, the message may take up to 8 hours to appear in the alert box.
Read the Message and Click Update Automatically
Watch the magic!
Your Piwik is now updated! Why not share your experience with others by writing a blog post, or spend some time doing new analysis on the Piwik numbers? Have you tried looking at your top websites referrers or sorted by decreasing bounce rate?
Or simply sit back for a few moments and enjoy the beauty of life!
The Manual Three-Step Update
If for some reason the one-click update doesn’t work for you, you can still update Piwik using FTP.
1) Back up your Configuration File
Please back up your Piwik configuration file. You can find this at:
This file contains the details for your existing installation, e.g. your database sign-in information and list of enabled plugins.
2) Replace the Piwik files with the latest version
You can download the latest Piwik release from builds.piwik.org/piwik.zip. After downloading it, you can extract it to your computer.
If you upload these files using FTP to your Piwik server, please make sure all files are transferred in binary mode. The new files should overwrite all the old files with the same names.
If you have SSH access to your server you can download the latest version and extract it directly from the server hosting Piwik:
# go into the the directory that contains your existing "piwik/" installation $ wget http://builds.piwik.org/piwik.zip # download latest version $ unzip -o piwik.zip # extract it to "piwik/" directory $ rm piwik.zip # delete the archive and read below the next step
3) Update Piwik
Visit your Piwik installation in your web browser. If your new instance of Piwik requires changes to be made to the database, you will see this screen:
This will update your database so that it is compatible with the latest code.
Please be patient: database updates (for example adding a new index) can take a few minutes. Do not close your browser or click refresh during this process. If you fail to carry out this step correctly your Piwik installation may display incorrectly or not work at all.
Database Upgrade for High Traffic Piwik Servers
For high traffic websites, where the update process could take from a few minutes to a few hours, it is highly recommended that you run the database update process in the command line. You can trigger the Piwik update by calling in your shell
$ ./path/to/piwik/console core:update
For Medium and High traffic Piwik servers, we also recommend that you turn off Visitor Tracking & turn off the Piwik User Interface while you run the upgrade on the command line. This will ensure that the DB Schema updates are finished as soon as possible and without concurrent read/write errors.
