has been solved. The reason for the problem is that both
1 and / etc/hosts files do not add domain names and network ip
2, nginx secondary domain name configuration files do not set domain names, just set localhost or 127.0.0.1 to domain names
3, the above 2 depends on 1, so if 1 does not change successfully, 2 will not succeed
