remove and reinstall/update stackdriver-agent

Question

Is there another method of removing and reinstalling/updating stackdriver-agent after pinning it to a certain version beyond removing to reinstall the latest?

• stackdriver-agent.x86_64 5.5.2-1001.el7
• stackdriver-agent.x86_64 5.5.2-1002.el7

Running "install -y stackdriver-agent" still uses stackdriver-agent.x86_64 0:5.5.2-1002.el7 even after "remove stackdriver-agent".

Is there a config file to make this change before pulling/installing the latest version which is 6.*?

Answer 1

Try going over the "Installing the Cloud Monitoring agent on a single VM" documentation which I've went through.

I was able to install, start, stop, remove and install another version of the agent.

Here's how I did it (using CentOS 6 box):

I've created a new CentOS 6 VM, added agent's repository to package list:

[wbogacz@centos ~]$ curl -sSO https://dl.google.com/cloudagents/add-monitoring-agent-repo.sh
[wbogacz@centos ~]$ sudo bash add-monitoring-agent-repo.sh
Adding agent repository for Red Hat.

Then listed all available versions for this OS:

[wbogacz@centos ~]$ sudo yum list --showduplicates stackdriver-agent

Version 6 of the agent is not available for CentOS 6 (it shows in CentOS 8).

I then installed 1001 version:

Listed installed agent's again and got nothing:

[wbogacz@centos ~]$  sudo yum list installed | grep stack
stackdriver-agent.x86_64

Started the agent:

[wbogacz@centos ~]$ sudo service stackdriver-agent start

Answer 2

The ONLY way I was able to get the new version installed was to remove from all prod systems the logging agent first, then the agent, then reinstall.

stackdriver-agent.x86_64 0:6.0.5-1.el7
