Download Mysqldump Mac

We're going to create a MySQL dump on an EC2 instance, compress and download this file to our local (Mac) machine.

This tutorial explains how to backup and restore MySQL or MariaDB databases from the command line using the mysqldump utility. The backup files created by the mysqldump utility are basically a set of SQL statements that can be used to recreate the original database. Mysqldump -all-databases alldatabasesdump.sql Because this command exports all databases, there is no need to specify a database name. All databases stored in mySQL will be dumped into the 'alldatabasesdump.sql' export file in the present working directory.

First of all let's connect to the instance using a ssh command:

We suggest that you use the MD5 checksums and GnuPG signatures to verify the integrity of the packages you download. MySQL Community Edition is a freely downloadable version of the world's most popular open source database that is supported by an active community of open source developers and enthusiasts.

where

• /path/to/your/*.pem is the location where the PEM key is stored.
• EC2_USERNAME is the username you log in with. If you used Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user.
• PUBLIC_DNS_NAME is the IP or DNS alias of the instance.

Then use the mysqldump utility to export a dump file from the database:

This file can be compressed

Note!-f option forcefully compresses a file named .sql even if there already exists a file named as .sql.gz.

Use scp to download the backup file from the EC2 instance to your local machine:

Note!scp means 'secure copy', which can copy files between computers on a network.

If needed the backup file can be removed on the EC2 instance:

macOS Update: While these instructions still work, there are new posts for recent versions of macOS, the latest being Install Apache, PHP, and MySQL on macOS Mojave.

I have installed Apache, PHP, and MySQL on Mac OS X since Leopard. Each time doing so by hand. Each version of Mac OS X having some minor difference. This post serves as much for my own record as to outline how to install Apache, MySQL, and PHP for a local development environment on Mac OS X Mountain Lion Mavericks.

I am aware of the several packages available, notably MAMP. These packages help get you started quickly. But they forego the learning experience and, as most developers report, eventually break. Personally, the choice to do it myself has proven invaluable.

It is important to remember Mac OS X runs atop UNIX. So all of these technologies install easily on Mac OS X. Furthermore, Apache and PHP are included by default. In the end, you only install MySQL then simply turn everything on.

First, open Terminal and switch to root to avoid permission issues while running these commands.

Enable Apache on Mac OS X

Note: Prior to Mountain Lion this was an option for Web Sharing in System Prefrences → Sharing.

Verify It works! by accessing http://localhost

Enable PHP for Apache

OS X Mavericks Update: You will need to rerun the steps in this section after upgrading an existing install to Mac OS X Mavericks.

Mysqldump Example

First, make a backup of the default Apache configuration. This is good practice and serves as a comparison against future versions of Mac OS X.

Now edit the Apache configuration. Feel free to use TextEdit if you are not familiar with vi.

Uncomment the following line (remove #):

Restart Apache:

Install MySQL

1. Download the MySQL DMG for Mac OS X
2. Install MySQL
3. Install Preference Pane
4. Open System Preferences → MySQL
5. Ensure the MySQL Server is running
6. Optionally, you can enable MySQL to start automatically. I do.

The README also suggests creating aliases for mysql and mysqladmin. However there are other commands that are helpful such as mysqldump. Instead, I updated my path to include /usr/local/mysql/bin.

Note: You will need to open a new Terminal window or run the command above for your path to update.

I also run mysql_secure_installation. While this isn't necessary, it's good practice.

Connect PHP and MySQL

You need to ensure PHP and MySQL can communicate with one another. There are several options to do so. I do the following:

Creating VirtualHosts

You could stop here. PHP, MySQL, and Apache are all running. However, all of your sites would have URLs like http://localhost/somesite/ pointing to /Library/WebServer/Documents/somesite. Not ideal for a local development environment.

OS X Mavericks Update: You will need to rerun the steps below to uncomment the vhostInclude after upgrading an existing install to Mac OS X Mavericks.

To run sites individually you need to enable VirtualHosts. To do so, we'll edit the Apache Configuration again.

Uncomment the following line:

Now Apache will load httpd-vhosts.conf. Let's edit this file.

Here is an example of VirtualHosts I've created.

The first VirtualHost points to /Library/WebServer/Documents. The first VirtualHost is important as it behaves like the default Apache configuration and used when no others match.

The second VirtualHost points to my dev workspace and I can access it directly from http://jason.local. For ease of development, I also configured some custom logs.

Note: I use the extension local. This avoids conflicts with any real extensions and serves as a reminder I'm in my local environment.

Restart Apache:

In order to access http://jason.local, you need to edit your hosts file.

Add the following line to the bottom:

I run the following to clear the local DNS cache:

Now you can access http://jason.local.

Note: You will need to create a new VirtualHost and edit your hosts file each time you make a new local site.

A note about permissions

You may receive 403 Forbidden when you visit your local site. This is likely a permissions issue. Simply put, the Apache user (_www) needs to have access to read, and sometimes write, your web directory.

If you are not familiar with permissions, read more. For now though, the easiest thing to do is ensure your web directory has permissions of 755. You can change permissions with the command:

In my case, all my files were under my local ~/Documents directory. Which by default is only readable by me. So I had to change permissions for my web directory all the way up to ~/Documents to resolve the 403 Forbidden issue.

See Full List On Mariadb.com

Note: There are many ways to solve permission issues. I have provided this as the easiest solution, not the best.

Install PHPMyAdmin

Unless you want to administer MySQL from the command line, I recommend installing PHPMyAdmin. I won't go into the details. Read the installation guide for more information. I install utility applications in the default directory. That way I can access them under, in this case, http://localhost/phpmyadmin.

Closing

A local development environment is a mandatory part of the Software Development Process. Given the ease at which you can install Apache, PHP, and MySQL on Mac OS X there really is no excuse.
