You can upgrade HAProxy Enterprise to version 2.4r1 on the following operating systems:
Upgrade to HAProxy Enterprise 2.4r1
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 2.4r1 by running the following command and replacing <HAProxy Enterprise Key> with the key you received when you registered:
$ wget https://www.haproxy.com/static/install_haproxy_enterprise.sh && sudo bash ./install_haproxy_enterprise.sh 2.4r1 <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:
$ # On Debian/Ubuntu $ sudo apt-get install hapee-2.4r1-lb-update
$ # On CentOS/RedHat/Oracle/Photon OS $ sudo yum install hapee-2.4r1-lb-update
$ # On SUSE $ sudo zypper install hapee-2.4r1-lb-update
$ # On FreeBSD $ sudo pkg install hapee-2.4r1-lb-update
Copy /etc/hapee-[previous-version]/hapee-lb.cfg over to /etc/hapee-2.4/hapee-lb.cfg and any associated files (maps, certificates, etc).
Disable the old HAProxy Enterprise version from starting with the system, as follows:
$ sudo systemctl disable hapee-<previous-version>-lb
Ensure that the new HAProxy Enterprise version starts with the system, as follows:
$ sudo systemctl enable hapee-2.4-lb
Stop the old HAProxy Enterprise daemon and start the new daemon:
$ sudo systemctl stop hapee-<previous-version>-lb $ sudo systemctl start hapee-2.4-lb
On older systems that do not have
$ sudo service hapee-2.4-lb start
tail -f /var/log/syslog(or distribution equivalent) to check for warnings or errors.
curl localhostto ensure that HAProxy Enterprise 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.
After you upgrade, see the section on additional packages on how to enable and configure each one.
After the new HAProxy Enterprise version has been running for a while, you can uninstall the old HAProxy Enterprise version. To uninstall a package:
$ # On Debian or Ubuntu $ sudo apt purge hapee-<previous-version>-lb $ # On CentOs/RedHat/Oracle/Photon OS $ sudo yum remove hapee-<previous-version>-lb $ # On SUSE $ sudo zypper remove hapee-<previous-version>-lb
