= How To Allow Remote Access MySQL/MariaDB/MYSQL Community
|
||
|
||
== Add New Rule to Firewalld
|
||
|
||
Open SQL port (3306) on FireWalld:
|
||
|
||
----
|
||
sudo firewall-cmd --permanent --zone=public --add-service=mysql
|
||
----
|
||
|
||
## OR ##
|
||
|
||
----
|
||
sudo firewall-cmd --permanent --zone=public --add-port=3306/tcp
|
||
----
|
||
|
||
== Restart firewalld.service
|
||
|
||
----
|
||
systemctl restart firewalld.service
|
||
----
|
||
|
||
== Editing Conf. Files:
|
||
|
||
Configuration files:
|
||
|
||
* MySQL -> `/etc/my.cnf/`
|
||
* MySQL Community -> `/etc/my.cnf.d/community-mysql-server.cnf`
|
||
* MariaDB -> `/etc/my.conf`
|
||
|
||
NOTE: you can ensure that with the following command `rpm -qc [package]`.
|
||
|
||
Navigate to the line that begins with the bind-address directive. It will look like this:
|
||
you could set this directive to a wildcard IP address, either *, ::, or 0.0.0.0:
|
||
|
||
----
|
||
bind-address = 0.0.0.0
|
||
----
|
||
|
||
After changing this line, save and close the file and then restart the MySQL service:
|
||
|
||
----
|
||
sudo systemctl restart {mysqld|mariadb}
|
||
----
|
||
|
||
== Creating a USER
|
||
|
||
----
|
||
CREATE USER 'your_username'@'host_ip_addr' IDENTIFIED BY 'your_password';
|
||
----
|
||
|
||
NOTE: Replace your_username and your_password depending on what you want the username and password to be. Here, host_ip_addr is the hostname or IP address of the computer from where you want to connect to the MySQL/MariaDB server. You can also use % as host_ip_addr if you want to connect from any computer. It can also be something like 192.168.2.% if you want to connect from computers from the IP range 192.168.2.1 – 192.168.2.254.
|
||
|
||
== Allow Access
|
||
|
||
----
|
||
GRANT ALL PRIVILEGES ON *.* TO 'your_username'@'%';
|
||
IDENTIFIED BY 'my-new-password' WITH GRANT OPTION;
|
||
----
|
||
|
||
#OR
|
||
|
||
It is common for people to want to create a "root" user that can connect from anywhere, so as an example, we'll do just that, but to improve on it we'll create
|
||
a root user that can connect from anywhere on the local area network (LAN)
|
||
|
||
----
|
||
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.100.%'
|
||
IDENTIFIED BY 'my-new-password' WITH GRANT OPTION;
|
||
----
|
||
|
||
----
|
||
FLUSH PRIVILEGES;
|
||
----
|
||
|
||
== Connecting
|
||
|
||
----
|
||
mysql -u [USER] -h [IP] -p
|
||
----
