How to install Memcached using brew?

Let’s get started:

Approach-1)

Step-1 – Installation

Open Mac Terminal and type command brew install memcached.

bash$ brew install memcached

==> Installing dependencies for memcached: openssl and libevent
==> Installing memcached dependency: openssl
==> Downloading https://homebrew.bintray.com/bottles/openssl-1.0.2q.mojave.bottle.tar.gz
######################################################################## 100.0%
==> Pouring openssl-1.0.2q.mojave.bottle.tar.gz
==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have openssl first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find openssl you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl/include"

==> Summary
  /usr/local/Cellar/openssl/1.0.2q: 1,794 files, 12.1MB
==> Installing memcached dependency: libevent
==> Downloading https://homebrew.bintray.com/bottles/libevent-2.1.8.mojave.bottle.tar.gz
######################################################################## 100.0%
==> Pouring libevent-2.1.8.mojave.bottle.tar.gz
  /usr/local/Cellar/libevent/2.1.8: 846 files, 2.2MB
==> Installing memcached
==> Downloading https://homebrew.bintray.com/bottles/memcached-1.5.12.mojave.bottle.tar.gz
######################################################################## 100.0%
==> Pouring memcached-1.5.12.mojave.bottle.tar.gz
==> Caveats
To have launchd start memcached now and restart at login:
  brew services start memcached
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/memcached/bin/memcached
==> Summary
  /usr/local/Cellar/memcached/1.5.12: 11 files, 198.9KB
==> Caveats
==> openssl

  brew services start memcached
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/memcached/bin/memcached

Step-2: Verification

Verify that it’s started successfully.

Type command ps -few | grep memcached.

bash-3.2$ ps -few | grep memcached
110048994 88258 88202   0 12:31PM ttys000    0:00.00 grep memcached

You will see memcached process as part of a result.

By default Memcached runs on port 11211.

Using brew is the safest and easiest way to install Memcached on Mac OS X. If you don’t have brew installed locally then follow below manual approach.

Approach-2)

Install libevent manually.
