Strange BINDlogging problems ~~~

Strange BINDlogging problems ~~~ -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Log configuration is as follows:
Logging {
Channel "query_log "{
File "/var/named/query. log" versions 3 size 2 m;
Severity info;
Print-time yes;
Print-category yes;
};

Channel "bind_log "{
File "/var/named/bind. log" versions 3 size 2 m;
Severity info;
Print-time yes;
Print-severity yes;
Print-category yes;
};

Category queries {"query_log ";};
Category default {"bind_log ";};
};

Two machines are used for testing. When one machine is mounted, the following occurs:
Isc_log_open '/var/named/bind. log' failed: permission denied error. After modifying bing. log permissions, you can add logs. However, on an external server, you cannot modify the file permissions, disable SElinux, or modify the file ownership.
What's the reason?
