I followed instructions on installing mysql using brew from here https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e
brew services list shows below output
Name Status User Plist
mysql started <username> /Users/<username>/Library/LaunchAgents/homebrew.mxcl.mysql.plist
But when I run 'mysql' or 'mysqladmin -u root password '' I get error.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Can anybody tell the issue here.

What is your MySQL version? Recently MySQL v8 was released and it is causing problems.
I suggest to first stop the MySQL service via brew services stop mysql and then uninstall MySQL via brew uninstall mysql.
Next, please remove its data folder by executing rm -rf /usr/local/var/mysql.
After that please do brew upgrade.
If you want to install MySQL v5.7 just do
brew install mysql@5.7 && brew link --force mysql@5.7 && brew services start mysql@5.7
This also works for mysql@5.6 and mysql@5.5.
