Iv. Puppet configuration file Introduction

Put the master configuration files of Puppet in the/etc/puppet directory. Versions 3.8.7 have the following files:

Auth. conf modules puppet. conf

Where:

Puppet. conf is the Master configuration file of the Master daemon. It defines the running environment of the Master and starts loading files. The daemon performs a pre-check based on the file before it starts.

Daemon.

Auth. conf is mainly used to define the Agent's permission to access the directory on the Master. Without permission control, the Agent can access all resources on the Master server.

5. Install the nginx package and start the nginx Service

To install the nginx package, run the puppet resource command to generate the template and edit it.

[Root @ master1 ~] # Puppet resource package nginx
Package {'nginx ':
Ensure => 'absent ',
}
[Root @ master1 ~] # Puppet resource service nginx
Service {'nginx ':
Ensure => 'stopped ',
Enable => 'false ',
}

Puppet resource package is the template for generating the installation package, and puppet resource service is the template for generating the service.

Finally, the configuration file of the nginx package is as follows:

Package {'nginx ':
Ensure => 'present ',
}
Service {'nginx ':
Ensure => 'running ',
}

Apply the configuration file locally

# Puppet apply nginx. pp

Notice: Compiled catalog for master1.localdomain in environment production in 0.56 seconds
Notice:/Stage [main]/Main/Package [nginx]/ensure: created
Notice:/Stage [main]/Main/Service [nginx]/ensure: ensure changed 'stopped 'to 'running'
Notice: Finished catalog run in 5.76 seconds

Check whether the nginx package is installed and whether the service is started.

[Root @ master1 ~] # Rpm-qa | grep nginx
Nginx-1.6.3-9.el7.x86_64
Nginx-filesystem-1.6.3-9.el7.noarch
[Root @ master1 ~] # Ps-ef | grep nginx
Root 3094 3070 0 00:00:00 pts/2 tailf/var/log/nginx/error. log
Root 3423 1 0? 00:00:00 nginx: master process/usr/sbin/nginx
