Yum localinstall

by Ulysses · Dec 24, 2020

Here’s how to install a RPM locally. Download the RPM first.

wget https://domain.com/path/to/file/rpmfile1.rpm
wget https://domain.com/path/to/file/rpmfile2.rpm

wget https://domain.com/path/to/file/rpmfile1.rpm wget https://domain.com/path/to/file/rpmfile2.rpm

Then install RPM from a local file.

yum localinstall /path/to/rpmfile1.rpm
yum localinstall /path/to/rpmfile2.rpm

yum localinstall /path/to/rpmfile1.rpm yum localinstall /path/to/rpmfile2.rpm

GCP Load Balancer Local Routing Table

by Ulysses · Jul 29, 2019

Test if the GCP Load Balancer is working by sending a curl command from the backend VM.

Assume the load balancer IP address is 10.1.2.99, and the VM is called vm-a1.

curl http://10.1.2.99

curl http://10.1.2.99

The end result is …

Page served from: vm-a1

Page served from: vm-a1

Make sure there’s an entry in the local table that matches the IP of the load balancer.

ip route show table local | grep 10.1.2.99

ip route show table local | grep 10.1.2.99

If not, add it.

ip route add to local 10.1.2.99/32 dev eth0 proto 66

ip route add to local 10.1.2.99/32 dev eth0 proto 66
