I'm trying to run Elastic search in an Ubuntu EC2 machine (t2.medium).
But I'm getting the message:
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
How can I increase the vm.max_map_count value?

The maximum map count check checks that the kernel allows a process to have at least 262,144 memory-mapped areas and is enforced on Linux only. To pass the maximum map count check, you must configure vm. max_map_count via sysctl to be at least 262144 .
On Linux, you can increase the limits by running the following command as root: sysctl -w vm.max_map_count=262144 To set this value permanently, update the vm.max_map_count setting in /etc/sysctl.conf. To verify after rebooting, run sysctl vm.max_map_count.
When vm.max_map_count is larger, processes are allowed to make the kernel allocate more memory for this purpose. 4. Does the kernel preallocate memory according to this setting? No. The memory is allocated only when a process actually needs the map areas.
The default operating system limits on mmap counts is likely to be too low, which may result in out of memory exceptions. On Linux, you can increase the limits by running the following command as root: To set this value permanently, update the vm.max_map_count setting in /etc/sysctl.conf.
The vm.max_map_count=262144 setting should be set permanently in /etc/sysctl.conf Show activity on this post. Thanks for contributing an answer to Stack Overflow!

To make it persistent, you can add this line:
vm.max_map_count=262144
in your /etc/sysctl.conf and run
$ sudo sysctl -p
to reload configuration with new value

I use
# sysctl -w vm.max_map_count=262144
And for the persistence configuration
# echo "vm.max_map_count=262144" >> /etc/sysctl.conf

Note that
From version 207 and 21x, systemd only applies settings from /etc/sysctl.d/*.conf and /usr/lib/sysctl.d/*.conf. If you had customized /etc/sysctl.conf, you need to rename it as /etc/sysctl.d/99-sysctl.conf. If you had e.g. /etc/sysctl.d/foo, you need to rename it to /etc/sysctl.d/foo.conf.
See https://wiki.archlinux.org/index.php/sysctl#Configuration
So add vm.max_map_count=262144 in /etc/sysctl.d/99-sysctl.conf and then run
sudo sysctl --system

sysctl -w vm.max_map_count=262144
When:
permission denied on key 'vm.max_map_count'
sudo sysctl -w vm.max_map_count=262144
