To perform appliance updates manually:
MWG 7.7.2 will use the engine update proxy for system updates such as yum:
- Open the MWG Manager.
- Click Configuration, Central Management.
- Scroll down to Automatic Engine Updates and select Enable update proxies.
- Click Add and enter the details of your next hop proxy. For example, host name or IP, port.
- Save your changes and start your system update:
- Select Configuration, Appliances.
- On the appliances tree, select the appliance where you want to perform the upgrade. The appliance toolbar appears on the upper-right corner of the tab.
- Click Update Appliance Software.
The upgrade starts, and you are logged off from the interface. When the upgrade is complete, a message is displayed to inform you about the completion.
IMPORTANT: The service will be restarted during the update. During this time, the proxy is not accessible for end users.
In MWG versions earlier than 7.7.2, you will need to set the update proxy using the command line.
- Log on to the MWG appliance via SSH with the root user.
- Use one of the following commands to perform the update:
http_proxy="http://192.168.100.120:3128" yum update -y
If username and password are required to access the next hop proxy, use the following syntax:
http_proxy="http://<username>:<password>@192.168.100.120:3128" yum update -y
In both of these examples:
- 192.168.100.120 represents an example proxy IP address and 3128 is an example proxy port.
- yum update -y performs the update by downloading all updated packages and installing them.
The updates are performed without additional warnings. After the installation completes, McAfee strongly recommends that you perform a complete reboot by typing the following command in the command line:
reboot
