SaltStack management tools allow administrators to create a consistent management system for multiple operating systems, including VMware vSphere environments.

SaltStack acts on servant and master topologies. SaltStack in combination with specific commands can be executed on one or more subordinates. To achieve this, Salt Master can issue commands such as salt'* 'cmd.run' ls-l /'.

In addition to running remote commands, SaltStack allows administrators to use "grain". Grain can run remote queries on SaltStack servants, so collect status information for servants and allow administrators to store information in a central location. SaltStack can also help administrators define the expected state on the target system. These states are applied using .sls files, which contain very specific requirements on how to obtain the desired state on the system.

Server installation

1) download the corresponding version of the extended source configuration file epel.repo from the Ali Cloud image address http://mirrors.aliyun.com/repo/ and upload it to the local / etc/yum.repos.d directory

2) yum install salt-master

Systemctl enable salt-master.service

Mkdir-p / srv/salt/ {dev,prod}

Edit configuration file / etc/salt/master

[

File_roots:

Base:

/ srv/salt/

Dev:/srv/salt/dev

Prod:/srv/salt/prod

]

Systemctl start salt-master.service

Client installation

1) just like the server installation, upload epel.repo to the local / etc/yum.repos.d directory

2) yum install salt-minion

Systemctl enable salt-minion.service

Edit configuration file / etc/salt/minion

[

Master: 192.168.233.100

Id: test01

]

Systemctl start salt-minion.service

Add Host

Execute salt-key-L on the master node to view the minion nodes that can be added

Execute salt-key-A to add all nodes, select y, and then use salt-key-L to view the following:

4. Common command

1) Test connectivity salt 'test01' test.ping

2) execute the command salt 'test01' cmd.run' df-h' remotely

3) File distribution salt-cp''/ etc/hosts / etc

4) use sls script
