Installing Redis 6.0.3 w/ TLS via Homebrew

README.md

Redis 6.0 w/ TLS

Redis 6 introduced native TLS support. This means that you can now use redis-cli to connect to AWS, GCP, Azure Redis instances that require TLS connections using the -tls flag. Unfortunately TLS is disabled by default and installing Redis via homebrew won't inlcude the TLS features enabled. Below is a quick guide on how to install Redis w/ TLS enabled.

Installation Guide

1. Install the OpenSSL development library dependencies

   $ brew install openssl 

2. Create relevant symlinks so that the Redis make install script can locate the OpenSSL development libraries

   cd /usr/local/include
   ln -s ../opt/openssl/include/openssl .
   cd /usr/local/lib
   ln -s ../opt/openssl/lib/libssl.a .
   ln -s ../opt/openssl/lib/libcrypto.dylib .

3. Install Redis w/ BUILD_TLS=yes enabled

   $ brew install https://gist.githubusercontent.com/dmlittle/1a449c1b22b58a76316c0bddbf97585b/raw/66ac95390527c1698296d3a7f72cfcca9ad242c6/redis.rb
