Upgrading on Debian 10 (Buster)
Update HAProxy Enterprise to the latest build
The update procedure installs the latest build for your current HAProxy Enterprise version in order to benefit from the newest bug fixes.
Run the following command:
apt update apt upgrade
Upgrade to HAProxy Enterprise 2.0r1 from a previous version
The following upgrade procedure installs a new major version of HAProxy Enterprise.
Take the server that you want to upgrade out of the cluster.
Install HAProxy Enterprise 2.0r1 by running the following command and replacing <HAProxy Enterprise Key> with the key you received when you registered:
curl -s https://cdn.haproxy.com/static/install_haproxy_enterprise.sh | sudo bash /dev/stdin 2.0r1 <HAProxy Enterprise key>
Update additional modules: you may be running additional modules with HAProxy Enterprise, which you must also reinstall when you upgrade to a new release. Install a package using its name, for example:
sudo apt-get install hapee-2.0r1-lb-update
/etc/hapee-2.0/hapee-lb.cfgand any associated files (maps/certificates/etc).
Disable the old HAProxy Enterprise version from starting with the system, as follows:
systemctl disable hapee-<previousversion>-lb
Ensure that the new HAProxy Enterprise version starts with the system, as follows:
systemctl enable hapee-2.0-lb
Stop the old HAProxy Enterprise daemon and start the new daemon:
systemctl hapee-<previousversion>-lb stop systemctl hapee-2.0-lb start
On older systems that do not have
sudo service hapee-2.0-lb start
tail -f /var/log/syslog(or distribution equivalent) to check for warnings or errors.
wget localhostto ensure that HAProxy is responding. Adjust address/port as needed, and use a local address that is currently active on the box and not a VRRP IP.
Put the upgraded server back into the cluster.
Repeat this procedure on secondary servers.
For the additional modules, see their corresponding documentations for instructions on how to enable and configure each package.
After the new HAProxy Enterprise version has been running for a while, you can uninstall the old HAProxy Enterprise version. To uninstall a package:
apt purge <package_name>
