Installing and Running MySQL on Mac

Writing by on Friday, 27 of May , 2016 at 7:35 am

Painful process, but you will need to see what works for you.

Say you’ve done the following:

  • Downloaded the DMG and installed MySQL on your Mac (and it provided you a password)
  • Started it from System Preferences -> MySQL
  • Now you tried different ways to connect to MySQL but are not able to login to localhost
  • So, then you tried brew and it didn’t work. Go ahead and remove mysql from brew
    • sudo brew remove mysql
    • brew cleanup

Now, here’s what worked for me, thanks to the following:


# Start MySQL in Safe Mode
$ sudo /usr/local/mysql/bin/mysqld_safe –skip-grant-tables

# Connect to MySQL as root (without password)
$ sudo /usr/local/mysql/bin/mysql -u root

# Update the password
mysql>use mysql;
mysql>show tables;
mysql> update user set authentication_string=password(‘new_password’) where user=’root’;

# Kill the mysql safe process and start it from System Preferences -> MySQL
alias mysql=’/usr/local/mysql/bin/mysql -uroot -ppassword’

That worked for me and I was able to kill the mysql safe-mode process and connect to MySQL through CLI as well as a GUI like Sequel Pro.

Optionally, to add python drivers that will fail further if the following is not done.

# add this to your $PATH
export PATH=$PATH:/usr/local/mysql/bin

# pip install in the right venv
pip install MySQL-python

Connection refused while trying to ssh localhost on Mac

Writing by on Sunday, 15 of May , 2016 at 4:04 am

Although SSH is available on the Mac, you need to enable Remote Login. Otherwise you will see

$ ssh localhost
ssh: connect to host localhost port 22: Connection refused

Good article from StackOverflow describes this

System Preferences -> (under) Internet & Networking -> Sharing -> check Remote Login and select the users

Mac : Show all users login after restart

Writing by on Tuesday, 22 of September , 2015 at 5:34 am

If FileVault encryption is on and you’re not able to see other user accounts to login with:

System Preferences -> Privacy & Security -> FileVault -> Enable users…
Select the account and provide the user’s password.
Restart and you should see that user to login with

sed: 1: “x.log”: extra characters at the end of x command

Writing by on Tuesday, 26 of May , 2015 at 5:25 am

While using sed in-place edit through sed -i on MacOS X, you will run into the following error.

This will ERROR out

mac:tmp shivdev$ sed -i “s/Apr/May/g” x.log
sed: 1: “x.log”: extra characters at the end of x command

Using an empty extension as shown below Will PASS

mac:tmp shivdev$ sed -i “” “s/Apr/May/g” x.log

The reason that it works fine on Ubuntu but not on MacOS is that it uses a BSD sed (not GNU sed like Ubuntu)

-i extension
Edit files in-place, saving backups with the specified extension.
If a zero-length extension is given, no backup will be saved. It
is not recommended to give a zero-length extension when in-place
editing files, as you risk corruption or partial content in situ-
ations where disk space is exhausted, etc.

iTerm Word Shortcuts

Writing by on Tuesday, 14 of April , 2015 at 6:32 am

I’m so used to iTerm now and really need word navigation. (I do miss Windows some of the time)

Well Meta Key to the rescue. Great article by Serge Émond. But, in a nutshell…

Esc + f (Move forward one word)
Esc + b (Move back one word)
Esc + d (Delete word to the right)
Esc + delete (Delete word to the left)

Connect to a Linux Samba Share from your Mac

Writing by on Friday, 13 of March , 2015 at 7:48 pm

Pretty straightforward. If you don’t have a samba share here’s How to Create a Network Share Via Samba Via CLI (Command-line interface/Linux Terminal). So now you have a Samba Share on Linux.

Here’s a snippet of my /etc/samba/smb.conf that contains the Linux folder on my VM that I would like to access from the Mac. (In your Mac: it will show up under /Volumes/vm_codebase).
Of course you can ssh into your Linux env, but this is more like mounting onto your Mac.

path = /home/shivdev/codebase
available = yes
valid users = shivdev
read only = no
browseable = yes
public = yes
writable = yes

From your Mac. Open Finder : Go –> Connect to Server… –> smb://vm –> Chose vm_codebase

Now you will see it under /Volumes/vm_codebase and is accessible like a regular folder.
