ติดตั้ง MySQL Server และ phpMyAdmin บน Alma Linux
ก่อนติดตั้ง ให้ทำการติดตั้ง Apache HTTPd Server และ PHP ก่อน
– การติดตั้ง Apache
– การติดตั้ง PHP 8
————————
1. ติดตั้ง MySQL Server
dnf install mysql-server mysql -y
2. สั่งสต๊าทการใช้งาน MySQL พร้อมกำหนดให้ทำงานตอนบู๊ตระบบ
[root@agriserv html]# systemctl start mysqld
[root@agriserv html]# systemctl enable mysqld
Created symlink /etc/systemd/system/multi-user.target.wants/mysqld.service → /usr/lib/systemd/system/mysqld.service.
3. ตรวจสอบสถานะ
systemctl status mysqld
4. กำหนดรหัสผ่าน MySQL ด้วยคำสั่ง mysql_secure_installation
[root@agriserv html]# mysql_secure_installation
Securing the MySQL server deployment.
Connecting to MySQL using a blank password.
VALIDATE PASSWORD COMPONENT 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 component?
Press y|Y for Yes, any other key for No: กดปุ่ม Enter
Please set the password for root here.
New password: รหัสผ่าน
Re-enter new password: ยืนยันรหัสผ่าน
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
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) : y
Success.
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
– 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
Success.
All done!

# dangerous unless properly secured by SSL
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin
<Directory /usr/share/phpMyAdmin/>
AddDefaultCharset UTF-8
Require all granted
