Puppet automated O & M troubleshooting case

Puppet automated O & M troubleshooting case

Recently, the following error is reported for a group of Puppet Agent machines maintained by Alibaba Cloud:

[Root @ client src] # puppetd -- test -- server server.bkjia.com

Notice: Run of Puppet configuration client already in progress; skipping

Solution:

Previously, use the online method to delete the puppet. lock file. The command is as follows:

Rm/var/lib/puppet/state/puppet. lock

The fault persists. Later, it was found that the fault occurred due to/etc/puppet/manifests/site. if the pp configuration file is not correctly written, we can correct it. In fact, it will be like the site in puppet server. pp and init. when there are major changes to the pp, it is best to first check with the puppet parser validate command, for example:

[Root @ server manifests] # puppet parser validate site. pp

Err: cocould not parse for environment production: Syntax error at 'source'; expected'}'

/Etc/puppet/manifests/site. pp: 8

Err: Try 'puppet help parser validate' for usage

As shown above, it is obvious that there is an error in line 8th of site. pp, prompting us to correct the error and troubleshooting after correction. In fact, the puppet parser validate command is very useful in puppet server syntax, for example:

Puppet parser validate node. pp

The node. pp syntax is incorrect. The error code} is missing in row 10th. The error message is as follows:

Err: cocould not parse for environment production: Syntax error at end of file; expected '}' at/etc/puppet/manifests/node. pp: 10

Err: Try 'puppet help parser validate' for usage
