Let WordPress remember your FTP credentials

I’ve found it quite useful to let WordPress remember my FTP information, so that adding new plugins/themes and doing security updates can happen quite quickly.

First, gather up your FTP username, password and host.
Next, open up the ./wp-config.php file. I like to put in the FTP information after the MySQL settings area:

[php]
/** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);

/** The Database Collate type. Don’t change this if in doubt. */
define(‘DB_COLLATE’, ”);

define(‘FTP_HOST’, ‘yourFTP_Hostname’);
define(‘FTP_USER’, ‘yourFTP_Username’);
define(‘FTP_PASS’, ‘yourFTP_Password’);
define(‘FTP_SSL’, false);
[/php]

To test it out, try to install a plugin.

In case of problems

2-3% of the time, WordPress has problems doing the FTP, even though I know that the information is correct. In that case, here is a workaround.

[sourcecode language=”plain”]
mysql>
mysql> select * from wp_options where option_name = ‘ftp_credentials’;
+———–+—————–+———————————————————————————————————-+———-+
| option_id | option_name | option_value | autoload |
+———–+—————–+———————————————————————————————————-+———-+
| 876 | ftp_credentials | a:3:{s:8:"hostname";s:12:"example.com";s:8:"username";s:8:"someUsername";s:15:"connection_type";s:3:"ftp";} | yes |
+———–+—————–+———————————————————————————————————-+———-+
1 row in set (0.00 sec)

[/sourcecode]

Take a look at what’s there, copy and paste it to a temporary safe place, then delete it from inside of MySQL:

[sourcecode language=”plain”]
mysql> delete from wp_options where option_name = ‘ftp_credentials’;
Query OK, 1 row affected (0.00 sec)

mysql>
[/sourcecode]

Switch back to your browser, and try installing the plug-in again. This time it should work.

Stash your mysql password in the .my.cnf file

Hopefully you are using usernames and passwords when accessing your MySQL databases. Security can make it hard to quickly jump in and start working in the MySQL shell if your password is quite complicated.

Here’s the solution:

create a ~/.my.cnf file and fill it with:

[client]
database=yourDBname
user=yourDBusername
password=yourSuperSecretPassword

Next, make sure that only you can read it:

chmod 600 ~/.my.cnf

Lastly, test it out:

user@host:~$ mysql
