Install Memcached Server

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

To install Memcached Server, follow these steps:

Download the memcache server.
Extract the zip file.
From the command prompt, navigate to memcached directory.
Run the following command:

memcached.exe -d install

For example, c:/memcached/memcached.exe -d install
Start the server from the Services or by running one of the following commands:
- c:/memcached/memcached.exe -d start
- net start memcached Server
  
  Now your memcached server is installed and is listening to port 11211.
By default, the server is set to 64MB memory limit, which is too small. To add the extra memory allocation, edit the registry to add the information. To increase the default memory size, in the Windows Run windows, type Regedit to display the Registry Editor window:
In the Registry Editor window, navigate to the following key:

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/memcached Server.
In the key, change the ImagePath entry with the following:

C:/memcached/memcached.exe -d runservice -m 2048

This way you will use 512 MB memory limit for your server.

If you now go back to the service section you should now see memcached installed, shown below:

If you are not seeing the above result, restart your computer. You now have memcached running.

Configure Load Balancers for Sending Host Information in Multinode

When user is installing Volt MX Foundry on multinode environment, the user should check whether the parameter: proxypreserveHost is set to On in the Loadbalancer configuration file to send host in the headers.

If the proxypreserveHost is not configured, the loadbalancer will not send host in the headers. Users cannot launch Volt MX Foundry Console.

The above configuration is based on the loadbalancer.

For example:

For Apache: preserveHost On
For HAProxy: preserve host flag is not required.
