Yum update -y klappt nicht?

Regelmäßiges update ist unverlässlich – doch was tun, wenn die Meldung kommt:

Error Summary
Disk Requirements: At least 11MB more space needed on the /boot filesystem.

Folgender Lösungsvorschlag:

To check the free space on /boot I ran the following command: df -h

Which gave the following output:

Filesystem Size Used Avail Use% Mounted on
/dev/vda3 136G 60G 70G 46% /
tmpfs 5.3G 0 5.3G 0% /dev/shm
/dev/vda1 99M 77M 17M 82% /boot
/usr/tmpDSK 1.3G 35M 1.2G 3% /tmp

As you can see the boot partition is 82% full.

To list installed kernels use this command:

rpm -qa | grep kernel

The result:

kernel-2.6.32-220.7.1.el6.x86_64
kernel-headers-2.6.32-358.2.1.el6.x86_64
dracut-kernel-004-303.el6.noarch
kernel-2.6.32-279.19.1.el6.x86_64
kernel-firmware-2.6.32-358.2.1.el6.noarch
kernel-2.6.32-279.9.1.el6.x86_64

So to remove the oldest kernel, I ran:

rpm -e kernel-2.6.32-220.7.1.el6.x86_64

Then: df -h

Output:

Filesystem Size Used Avail Use% Mounted on
/dev/vda3 136G 60G 70G 46% /
tmpfs 5.3G 0 5.3G 0% /dev/shm
/dev/vda1 99M 52M 42M 56% /boot
/usr/tmpDSK 1.3G 35M 1.2G 3% /tmp

As you can see that freed up more than the 11MB needed. So I retried yum -y update kernel and this time it works.

MySQL startet nicht?

Unit mysqld.service failed to load: No such file or directory.

Wenn die Datenbank nicht starten will, viellicht liegt es daran, dass MariaDB installiert ist und dann ein anderer Befehl erforderlich ist:

systemctl start mariadb.service
