phpMyAdmin with PHP v. 7.0

Description

phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web. phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc) can be performed via the user interface, while you still have the ability to directly execute any SQL statement.

MySQL DB Server

MySQL DB Server

Description

MySQL is a very fast, multi-threaded, multi-user and robust SQL (Structured Query Language) database server.

WWW: http://www.mysql.com.

Preparation for Installation

Start PuTTY on a Windows PC, Terminal on a Mac or similar terminal application on a Linux PC.

In this example Terminal on a Mac is used.

Open a remote SSH session to the server with:

Mac:~ user$ ssh user@192.168.1.4 [enter]
N.B.: Replace user@192.168.1.4 with User ID and IP Address on Your server!
[user@server ~]$

Enable superuser privileges with:

[user@server ~]$ sudo -s [enter]
Password: <-- passwd [enter]
[root@server /usr/home/user]#

N.B.: Enter user password, not the root password!

Securing MySQL

Protect the MySQL installation with:

[root@server /usr/home/user]# mysql_secure_installation [enter]

Securing the MySQL server deployment.

Connecting to MySQL server using password in '/root/.mysql_secret'

VALIDATE PASSWORD PLUGIN can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: Y [enter]

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2 [enter]
Using existing password for root.

Estimated strength of the password: 100 
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N [enter]

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y [enter]
Success.


Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : [enter]

 ... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.


Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y [enter]
 - Dropping test database...
Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y [enter]
Success.

All done! 
[root@server /usr/home/user]#

N.B.: The root password for MySQL can be found in file /root/.mysql_secret!

[root@server /usr/home/user]# cat /root/.mysql_secret
# Password set for user 'root@localhost' at 2017-02-20 21:33:40 
{passwd}
[root@server /usr/home/user]#

Logon to the MySQL service as root with:

[root@server /usr/home/user]# mysql -u root -p [enter]

MySQL User Administration

To set the MySQL root password for the first time:

[root@server /usr/home/user]# mysqladmin -u root password 'passwd' [enter]
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
[root@server /usr/home/user]#

To change the MySQL root password:

[root@server /usr/home/user]# mysqladmin -u root -p'oldpassword' password 'newpasswd' [enter]
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
[root@server /usr/home/user]#

Tweaking MySQL

Default minimum character search length in MySQL is 4 characters. This can easily be adjusted to let’s say 2 characters.

[root@server /usr/home/user]# ee /usr/local/etc/my.cnf

…and add the following text:

[mysqld]
ft_min_word_len=2

[myisamchk]
ft_min_word_len=2

[mysqldump]
ignore-table=mysql.event

Manually restart MySQL Server with;

[root@server /usr/home/user]# service mysql-server restart [enter]
Stopping mysql.
Waiting for PIDS: 939.
Starting mysql.
[root@server /usr/home/user]#

Optional: packet filter (pf)

Network access to the MySQL Server service must be enabled in the packet filter (pf) configuration file.

Start editing file /etc/pf.conf with:

[root@server /usr/home/user]# ee /etc/pf.conf [enter]

…and add default port information to enable access to the MySQL Server service from clients on the local network as in this example:

.
.
# Ports:
# 123 TCP       Network Time Protocol
.
.
# 3306 TCP      MySQL database system

tcp_pass="{ 123, 3306 }"
.
.

Check /etc/pf.conf for errors, but do not load ruleset with:

[root@server /usr/home/user]# pfctl -vvnf /etc/pf.conf [enter]

…and then reload /etc/pf.conf with:

[root@server /usr/home/user]# service pf reload [enter]
Reloading pf rules.
[root@server /usr/home/user]#

Move a MySQL Database from one server to another via SSH

Create a new empty database on the receiving server, srv2:

On the server with the database, srv1:

[root@srv1 ~]# mysqldump -u{user} -p{password} {db_name} | ssh user@{IP Address srv2} "mysql -u{user} -p{password} {db_name}" [enter]
[root@srv1 ~]#

Using the parameters -e -f -q -Q -K for mysqldump a good idea and will make the insert faster and more secure. Look them up in the docs!
