Troubleshooting of samba error in Linux configuration startup

systemctl start SMB indicates an error and the firewall needs to be closed. Set SELinux to disabled through sudo VI/etc/SELinux/config, and systemctl start SMB succeeds again. Windows connects to Linux through samba and prompts an error. You need to turn off the firewall through sudo systemctl stop firewalld. Then, connect again and succeed
