Upgrade HAProxy Enterprise
To upgrade to HAProxy Enterprise 2.1r1 from a previous version you will need to install HAProxy Enterprise 2.1r1 and any additional modules you were using before you can switch to it and uninstall the previous version.
Supported Operating Systems
HAProxy Enterprise can be upgraded to version 2.1r1 on the following Operating Systems.
Upgrade to HAProxy Enterprise 2.1r1
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 2.1r1 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 2.1r1 <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 or Ubuntu sudo apt-get install hapee-2.1r1-lb-update # On CentOS or RedHat yum install hapee-2.1r1-lb-udpate # On SUSE zypper install hapee-2.1r1-lb-update
/etc/hapee-2.1/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-2.1-lb
Stop the old HAProxy Enterprise daemon and start the new daemon:
systemctl hapee-<previousversion>-lb stop systemctl hapee-2.1-lb start
On older systems that do not have
sudo service hapee-2.1-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:
# On RedHat or CentOS yum remove <package_name> # On Debian or Ubuntu apt purge <package_name> # On SUSE zypper remove <package_name>
