How to deploy apache in batches with Saltstack? I believe that many novice rookies have not yet learned this skill, through the summary of this article, I hope you can learn to use Saltstack to deploy apache in batches.

The experimental environment prepares the name, role address, centos7-minmaster192.168.142.172centos7-min2client192.168.142.110 experiment step 1, the main server-- control node

Install the epel source and install the control side

Yum install-y epel-release / / install the epel source yum-y install salt-master / / install the console

Modify the control side master configuration file

The vi / etc/salt/master// is modified as follows: 15 lines interface: 192.168.142.172 / / listening address line 215 auto_accept: True / / avoid running salt-key to confirm the root location of the certificate authentication 416 line file_roots: base:-/ srv/salt / / saltstack file, the directory needs to manually create 710 line group categories: (here there is only one client in the experimental environment Only one can be set) nodegroups: group1: 'web01.saltstack.com'552 line pillar_opts: True / / enable pillar function, synchronize file function 529line pillar_roots: base:-/ srv/pillar / / pillar's home directory, which needs to be created manually

Set up a salt&pillar directory

Mkdir / srv/saltmkdir / srv/pillar

Start the service and turn off the core protection function

Systemctl start salt-mastersystemctl enable salt-master// turns off the core function setenforce 0

Check the status of service startup

Netstat-anpt | egrep '4505 | the dedicated port for message publishing of salt / / 4506 is the port tcp 0 0192.168.142.172LISTEN 13704/pythontcp 0192.168.142.172LISTEN 13704/pythontcp 0192.168.142.172LISTEN 13704/pythontcp: 36688 ESTABLISHED 13704/pythontcp 0 192.168.142.172 ESTABLISHED 13692/python 4505 192.168.142.110 ESTABLISHED 13692/python II, Slave server-controlled node

Install the epel source and install the controlled terminal

Yum install-y epel-release / / install the epel source yum-y install salt-minion / / install the controlled side

Modify the configuration file of the controlled side

The configuration of vi / etc/salt/minion// is modified as follows: 16 lines master: 192.168.172.142 / / specify IP78 line id: web01.saltstack.com / / specify the hostname of the controlled side

Start the service

/ / start the service systemctl start salt-minion of the controlled side

Check at the main control terminal

/ / Test the communication status between the master terminal and the controlled terminal (the * symbol represents all the controlled hosts) salt'* 'test.pingweb01.saltstack.com: True// check the key salt-key-LAccepted Keys:web01.saltstack.comDenied Keys:Unaccepted Keys:web01.saltstack.comRejected Keys: note:

The following occurs during the inspection:

Salt request timed out. The master is not responding. If this error persists after verifying the master is up, worker_threads may need to be increased.

Please check the configuration file format yourself or restart the server.
