Question or issue on macOS:

I’m trying to setup up MySQL on mac os 10.6 using Homebrew by brew install mysql 5.1.52.

Everything goes well and I am also successful with the mysql_install_db.
However when I try to connect to the server using:

I get:

I’ve tried to access mysqladmin or mysql using -u root -proot as well,
but it doesn’t work with or without password.

This is a brand new installation on a brand new machine and as far as I know the new installation must be accessible without a root password. I also tried:

but I also get

How to solve this problem?

Solution no. 1:

I think one can end up in this position with older versions of mysql already installed. I had the same problem and none of the above solutions worked for me. I fixed it thus:

Used brew’s remove & cleanup commands, unloaded the launchctl script, then deleted the mysql directory in /usr/local/var, deleted my existing /etc/my.cnf (leave that one up to you, should it apply) and launchctl plist

Updated the string for the plist. Note also your alternate security script directory will be based on which version of MySQL you are installing.

Step-by-step:

I then started from scratch:

1. installed mysql with brew install mysql

2. ran the commands brew suggested: (see note: below)

3. Start mysql with mysql.server start command, to be able to log on it

4. Used the alternate security script:

5. Followed the launchctl section from the brew package script output such as,

Note: the --force bit on brew cleanup will also cleanup outdated kegs, think it’s a new-ish homebrew feature.

Note the second: a commenter says step 2 is not required. I don’t want to test it, so YMMV!

Solution no. 2:

Here are detailed instructions combining getting rid of all MySQL from your Mac then installing it The Brew Way as Sedorner wrote above:

Remove MySQL completely per The Tech Lab

• ps -ax | grep mysql
• stop and kill any MySQL processes
• sudo rm /usr/local/mysql
• sudo rm -rf /usr/local/var/mysql
• sudo rm -rf /usr/local/mysql*
• sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• sudo rm -rf /Library/StartupItems/MySQLCOM
• sudo rm -rf /Library/PreferencePanes/My*
• launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
• edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
• rm -rf ~/Library/PreferencePanes/My*
• sudo rm -rf /Library/Receipts/mysql*
• sudo rm -rf /Library/Receipts/MySQL*
• sudo rm -rf /private/var/db/receipts/*mysql*
• sudo rm -rf /tmp/mysql*
• try to run mysql, it shouldn’t work

Brew install MySQL per user Sedorner from this StackOverflow answer

• brew doctor and fix any errors

• brew remove mysql

• brew cleanup

• brew update

• brew install mysql

• unset TMPDIR

• mysql.server start

• run the commands Brew suggests, add MySQL to launchctl so it automatically launches at startup

mysql should now work and be running all the time as expected

Godspeed.

Solution no. 3:

Had the same problem. Seems like there is something wrong with the set up instructions or the initial tables that are being created. This is how I got mysqld running on my machine.

If the mysqld server is already running on your Mac, stop it first with:

launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

Start the mysqld server with the following command which lets anyone log in with full permissions.

mysqld_safe --skip-grant-tables

Then run mysql -u root which should now let you log in successfully without a password. The following command should reset all the root passwords.

UPDATE mysql.user SET Password=PASSWORD('NewPassword') WHERE User='root'; FLUSH PRIVILEGES;

Now if you kill the running copy of mysqld_safe and start it up again without the skip-grant-tables option, you should be able to log in with mysql -u root -p and the new password you just set.

Install Mysql 5.7 Mac Catalina

Solution no. 4:

If brew installed MySQL 5.7, the process is a bit different than for previous versions.
In order to reset the root password, proceed as follows:

A temporary password will be printed to the console and it can only be used for updating the root password:

Solution no. 5:

Okay I had the same issue and solved it. For some reason the mysql_secure_installation script doesn’t work out of the box when using Homebrew to install mysql, so I did it manually. On the CLI enter:

That should get you into mysql. Now do the following (taken from mysql_secure_installation):

Now exit and get back into mysql with: mysql -u root -p

Solution no. 6:

I had the same problem just now. If you brew info mysql and follow the steps it looks like the root password should be new-password if I remember correctly. I was seeing the same thing you are seeing. This article helped me the most.

It turned out I didn’t have any accounts created for me. When I logged in after running mysqld_safe and did select * from user; no rows were returned. I opened the MySQLWorkbench with the mysqld_safe running and added a root account with all the privs I expected. This are working well for me now.

Solution no. 7:

Can I Install Mysql On Mac

If mysql is already installed

Stop mysql completely.

1. mysql.server stop <– may need editing based on your version
2. ps -ef | grep mysql <– lists processes with mysql in their name
3. kill [PID] <– kill the processes by PID

Remove files. Instructions above are good. I’ll add:

1. sudo find /. -name '*mysql*'
2. Using your judgement, rm -rf these files. Note that many programs have drivers for mysql which you do not want to remove. For example, don’t delete stuff in a PHP install’s directory. Do remove stuff in its own mysql directory.

Install

Hopefully you have homebrew. If not, download it.

I like to run brew as root, but I don’t think you have to. Edit 2018: you can’t run brew as root anymore

1. sudo brew update
2. sudo brew install cmake <– dependency for mysql, useful
3. sudo brew install openssl <– dependency for mysql, useful
4. sudo brew info mysql <– skim through this… it gives you some idea of what’s coming next
5. sudo brew install mysql --with-embedded; say done <– Installs mysql with the embedded server. Tells you when it finishes (my install took 10 minutes)

Afterwards

1. sudo chown -R mysql /usr/local/var/mysql/ <– mysql wouldn’t work for me until I ran this command
2. sudo mysql.server start <– once again, the exact syntax may vary
3. Create users in mysql (http://dev.mysql.com/doc/refman/5.7/en/create-user.html). Remember to add a password for the root user.

Solution no. 8:

brew info mysql

mysql.service start

or mysql -u root

I’m looking for a solution for some time but I can not solve my problem. I tried several solutions in stackoverflow.com but no this helping me.

Solution no. 9:

TL;DR

MySQL server might not be running after installation with Brew. Try brew services start mysql or just mysql.server start if you don’t want MySQL to run as a background service.

Full Story:

I just installed MySQL (stable) 5.7.17 on a new MacBook Pro running Sierra and also got an error when running mysql_secure_installation:

Say what?

According to the installation info from Brew, mysql_secure_installation should prompt me to… secure the installation. I figured the MySQL server might not be running and rightly so. Running brew services start mysql and then mysql_secure_installation worked like a charm.

Solution no. 10:

Here is an update for MySQL 5.7

Hope this helps!

Getting Started with 'Terminal' - MUST READ Before You Start Programming

Programmers use 'Terminal' to issue commands, instead of the graphical user interface - which is meant for common users.

You MUST have some basic knowledge on using the Terminal and the file system. Read 'Unix Survival Guide for Mac & Ubuntu - Terminal, File System and Users'.

Programming Text Editors for Mac

TextEdit for Mac

TextEdit (the default text editor in Mac OS X) is NOT a programming text editor, as it lacks features like syntax highlighting. I strongly suggest you install a programming text editor.

To use TextEdit to write source file, you need to open a new file ⇒ choose 'Format' ⇒ 'Make Plain Text'.

You can open an existing file in TextEdit from Terminal by issuing:

nano (or pico) Command-line Text Editor

nano is a GNU text editor that is available for Unix Systems (including Mac OS X), that is suitable for creating/editing small files. To start nano, open a Terminal and issue:

You can run nano with superuser (for accessing restricted directories), as follows:

How to Install MySQL 5.6 on Mac OS X 10.7 Lion

Install MySQL using the DMG Package

Reference: 'Installing MySQL on Mac OS X' @ http://dev.mysql.com/doc/refman/5.6/en/macosx-installation.html.

Step 1: Download and Install MySQL

Download the MySQL 'DMG Archive':

1. Go to http://dev.mysql.com/downloads/mysql/. In platform, select the 'Mac OS X'.
2. Select the appropriate 'DMG Archive' for your specific Mac OS version:
   • Click the Apple logo ⇒ 'About this Mac' to check your Mac OS version.
   • Read http://support.apple.com/kb/ht3696 to check if your OS is 32-bit or 64-bit.
   For example, Choose 'Mac OS X ver. 10.7 (x86, 64-bit), DMG Archive (117.5M)' for Lion and Core i7 processor.
3. Click 'No thanks, just start my download'.

To install MySQL:

1. Go to 'Downloads' ⇒ Double-click '.dmg' file downloaded.
2. Double-click 'mysql-5.5.{xx}-osx10.x-xxx.pkg' ⇒ Follow the instructions to install MySQL. Click continue if 'unindentified developer' warning dialog appeared.
3. MySQL will be installed in '/usr/local/mysql-5.5.{xx}-osx10.x-x86_xx' directory. A symbolic link '/usr/local/mysql' will be created automatically to the MySQL installed directory.
4. Eject the '.dmg' file.

Step 2: Configuring MySQL - Change TCP Port Number for MySQL Server

1. The default TCP port number used by MySQL Server is 3306.
2. [For novices: SKIP THIS STEP to run the MySQL Server on port 3306. Goto Step 3.]
   You can change the port number by editing the configuration file 'my.cnf' at directory '/usr/local/mysql'. To create this file, open a new 'Terminal' and run the 'nano' editor using this command: Modify the lines in green and add in the lines in red; and press ctrl-X to exit. (We use the 'nano' editor in this case, you can use any text editor, but run in superuser.)

Notes: On Unix/Mac, the MySQL read the options file in this order: '/etc/my.cnf', 'SYSCONFDIR/mf.cnf', '$MYSQL_HOME/my.cnf', '~/.my.cnf'.

Step 3: Start/Shutdown the MySQL Server

Open a new 'Terminal' and issue these commands to start the MySQL server:

To shutdown the server, start a new terminal and issue:

Step 4: Start/Stop a MySQL Client

Install Mysql Mac Catalina Operating System

Open a new 'Terminal' and issue this command to start a MySQL client with superuser root:

To terminate the client, issue command 'exit' (or 'quit') from the 'mysql>' prompt:

Notes:

1. You can use 'Activity Monitor' (under Applications/Utilities) to check if the MySQL Server is running. Look for process starting with mysqld.
2. The log messages are written to /usr/local/mysql/data/xxx.err, where xxx denotes your machine name. Issue 'sudo cat /usr/local/mysql/data/xxx.err' to view the messages.
3. If you get the following error message when starting a client: 'Can't connect to local MySQL server through socket '....', check your 'Activity Monitor' to see if the MySQL server has been started.

Step 5: (For Java Programmers) Install MySQL JDBC Driver

1. Download the latest JDBC driver from http://www.mysql.com/downloads ⇒ MySQL Connectors ⇒ Connector/J ⇒ Compressed TAR archive (e.g., mysql-connector-java-{5.x.xx}.tar.gz, where {5.x.xx} is the latest release number).
2. Double-click on the downloaded TAR file to expand into folder 'mysql-connector-java-{5.x.xx}'.
3. Open the expanded folder. Copy the JAR file 'mysql-connector-java-{5.x.xx}-bin.jar' to JDK's extension directory at '/Library/Java/Extension'.

How to Uninstall and Remove MySQL 5

1. Open a Terminal ⇒ Run the 'nano' editor to edit /etc/hostconfig, as follows: Delete this line if present: 'MYSQLCOM=-YES-'. Press cntl-x to exit 'nano' and enter 'Y' to save the file. The line 'MYSQLCOM=-YES-' starts MySQL automatically during startup.
2. Make sure that MySQL is not running (Open the 'Activity Monitor' under the 'Applications/Utilities', and check for the process 'mysqld'). Open a Terminal and issue 'rm -r' to remove these directories and their sub-directories (with 'f' indicating no confirmation prompt).

That's all!

How to Install Tomcat 7 on Mac

Step 1: Download and Install Tomcat

1. Goto http://tomcat.apache.org ⇒ Download ⇒ Tomcat 7.0 ⇒ 7.0.{xx} (where {xx} denotes the latest release) ⇒ Binary distribution ⇒ Core. Download the 'tar.gz' package (e.g., 'apache-tomcat-7.0.{xx}.tar.gz').
2. To install Tomcat:
   1. Goto '~/Downloads', double-click the downloaded TAR file (e.g., 'apache-tomcat-7.0.{xx}.tar.gz') to expand it into a folder (e.g., 'apache-tomcat-7.0.{xx}').
      (Notes for Advanced Users) Alternatively, you can use the tar command to expand the tarball as follow:
   2. Move the extracted folder (e.g., 'apache-tomcat-7.0.{xx}') to '/Applications'.
   3. Rename the folder 'tomcat', for ease of use.

(Notes for Advanced Users):

1. It is probably better to keep the tomcat in '/usr/local' or '/Library'.
2. Instead of renaming the tomcat's folder, it it better to create a symlink called tomcat as follows:
3. For security reason, you should not run Tomcat as root user. Instead, assign Tomat to user nobody (of group nobody):

Step 2: Configure Tomcat Server

Read 'Configure Tomcat Server'.

Step 3: Start the Tomcat Server

To start the Tomcat server, open a new 'Terminal' (Go ⇒ Utilities ⇒ Terminal) and issue:

Check for the Tomcat server's TCP port number from the console messages. The default is 8080.

To verify if the Tomcat server is started, start a browser (Safari) and issue URL http://localhost:8080, suppose that Tomcat is running on the default TCP port number of 8080.

Also try URL http://localhost:8080/examples which shows the Servlet/JSP examples.

Step 4: Shutdown the Tomcat Server

To shutdown the Tomcat server, you can simply press control-c (NOT command-c) on the tomcat console, or issue command:

Step 5: Servlet API

To write Java servlets, you need to COPY the Servlet API JAR file ('servlet-api.jar') from '/Applications/tomcat/lib' to the JDK's extension directory at '/Library/Java/Extension'.

Mac's Tips & Tweaks

Root (or Superuser, or Administrator)

In some cases (such as installing software and starting server), you need to be the so-called root user (or superuser or administrator) of your machine to complete some commands that require high privilege. Put 'sudo' (superuser do) in front of your command to run the command as root user, and provide the your password. Only authorized user can issue sudo command. For example, to start the MySQL server:
