Fedora 28 setup (After install)

17 May 2018 | 7 min read

What is about?

Fedora 28 already released maybe this is a perfect time to do clean format instead of upgrading the newest version because previously started from Fedora 25, I just upgrade when each time new version released.

Todo

Yes, there is lot of thing need to be configure again after clean formating. Here few of thing on my list :

1 - Change the hostname (note : Need to reboot after change the host name)

$ hostnamectl status # view current hostname
$ hostnamectl set-hostname --static "robbinespu" # set up new hostname

2 - Configure DNF : Use delta and fastest mirror (edit /etc/dnf/dnf.conf file)

[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
fastestmirror=true
deltarpm=true

Reset the MariaDB Root Password

29 March 2018 | 1 min read

If you forget your root MariaDB password, don’t worry and be sad because it can be reset easily with this tutorial.

  1. Stop the current MariaDB server instance, then restart it with an option to not ask for a password:

     $ sudo systemctl stop mariadb
     $ sudo mysqld_safe --skip-grant-tables &
    
  2. Reconnect to the MariaDB server with the MariaDB root account:

     $ mysql -u root
    
  3. Use the following commands to reset root’s password. Replace password with a strong password:

     use mysql;
     update user SET PASSWORD=PASSWORD("password") WHERE USER='root';
     flush privileges;
     exit
    
  4. Then restart MariaDB:

     $ sudo systemctl start mariadb
    

Done, everything will be fine. Now you should be able to access again with new password we update before.
