La solución
El permiso de /var/spool/squid/ era incorrecto.
# ls -ld /var/spool/squid drwxr-xr-x 2 root root 6 Apr 26 20:29 /var/spool/squid
1. Modifique la propiedad del directorio de root a squid con el siguiente comando:
# chown squid:squid /var/spool/squid
2. Verifique el permiso del directorio con el siguiente comando:
# ls -ld /var/spool/squid drwxr-xr-x 2 squid squid 6 Apr 26 20:29 /var/spool/squid
3. Inicie el servicio squid con el siguiente comando:
# systemctl start squid
4. Verifique el estado del servicio squid con el siguiente comando:
# systemctl status squid
