After “MariaDB with Secure Connections.”, my SQL server has Secure Connections. Now I have to add some options to phpMyAdmin and WordPress settings.
Their versions are MariaDB 10.2.9 win 32-bit, phpMyAdmin 4.7.4 and WordPress 4.8.2 on Windows 7 32-bit HE SP1.
Before this I confirmed SQL sever status when I connected to it by using CA information. I logged in the server by
mysql -u root -p --ssl-ca=/path/to/my_ca.crt and did
s. I had the result below:
-------------- mysql Ver 15.1 Distrib 10.2.9-MariaDB, for Win32 (AMD64) Connection id: 221 Current database: Current user: root@localhost SSL: Cipher in use is DHE-RSA-AES256-SHA Using delimiter: ; Server: MariaDB Server version: 10.2.9-MariaDB-log mariadb.org binary distribution Protocol version: 10 Connection: localhost via TCP/IP Server characterset: latin1 Db characterset: latin1 Client characterset: cp932 Conn. characterset: cp932 TCP port: 3306 Uptime: 25 min 57 sec Threads: 7 Questions: 14327 Slow queries: 18 Opens: 215 Flush tables: 1 Open tables: 209 Queries per second avg: 9.201 --------------
DHE-RSA-AES256-SHA is TLS v1.0. As I set
ssl_cipher=TLSv1.2, the server gave
have_ssl|DISABLED. I cannot use TLS v1.2 because of MariaDB Windows version built with YaSSL.
Next, I change my WordPress SQL user account settings on the server which requires TLS whenever the user connects to it.
GRANT SELECT,INSERT,UPDATE,DELETE on *.* to wpuser@localhost IDENTIFIED by 'password' require ssl;
I ended working on the command line.
Add the following lines to the config.inc.php file. See cfg_Servers_ssl.
In my case, the file already had
$cfg['Servers'][$i]['ssl_verify'] = false; because of this. I change this ‘false’ to ‘true’.
$cfg['Servers'][$i]['ssl'] = true;
$cfg['Servers'][$i]['ssl_key'] = '/path/to/MySQL.key';
$cfg['Servers'][$i]['ssl_cert'] = '/path/to/MySQL.crt';
$cfg['Servers'][$i]['ssl_ca'] = '/path/to/my_ca.crt';
$cfg['Servers'][$i]['ssl_verify'] = true;
I logged in phpMyAdmin as wpuser@localhost. It accepted me but required two more options. So I added the next lines to the config.inc.php file.
$cfg['Servers'][$i]['ssl_ca_path'] = '/path/to/';
$cfg['Servers'][$i]['ssl_ciphers'] = 'DHE-RSA-AES256-SHA';
Now I can connect to MariaDB secure server as wpuser@localhost from phpMyAdmin. Of course, you can set a user as ‘require ssl’ privilege by phpMyAdmin not by command line.
See “Secure DB Connection”.
define('MYSQL_CLIENT_FLAGS', MYSQLI_CLIENT_SSL); to the wp-config.php file. This time my CA cert is self-signed one, so I also added
I updated phpMyAdmin from 4.7.9 to 4.8.0 the day before yesterday. Although they wrote that…
