Salt error Job for salt-master.service failed because the control process exited with error code .,
Problem

& Amp; emsap ;? When I use salt on a virtual machine, I can't use salt because I read the document and learned it.

ps aux | grep salt

& Amp; emsap ;? We found that both salt-maste and salt-minion are there. You have to restart the salt-master service and try:

sudo service salt-master restart

However, an error is reported:

Job for salt-master.service failed because the control process exited with error code. See "systemctl status salt-master.service" and "journalctl -xe" for details.

Run the prompt command to view the error message:

?? According to the prompt, it is displayed that port 4505 cannot be bound (Port 4505 is used by default when you install salt, and can be modified in/etc/salt/master), and then use

netstat -lnput

?? Check the port number and find that no process occupies port 4505. Then I went to the Internet to find many methods-fruitless.
?? In the end, I found that my IP address had changed. Because of the virtual machine I used, the IP address suddenly changed and I was not given a little defense.
?? You can modify the IP address in/etc/salt/master. (for the normal operation of other services, I changed the default IP address 0: 0: 0: 0 to the IP address of the virtual machine, so the virtual machine cannot run successfully after the IP address is changed ).

??I would like to warn you that if you learn to use salt on a virtual machine and have no other requirements, do not change the IP settings in the master.

Update it in half an hour: Remember to change the IP address in minion, and in/etc/salt/minion, do not say it, and cry in the toilet ~~
