ubuntu用bind9自建DNS服务器时logging日志出现failed: permission denied解决方法
ubuntu用bind9自建DNS服务器时logging日志出现failed: permission denied解决方法：
日志文件要放在/var/log/named/目录下，比如：/var/log/named/bind.log
/etc/bind/目录下创建named.conf.log文件，内容如下：
logging {
channel bind_log {
file "/var/log/named/bind.log" versions 3 size 10m;
severity info;
print-category yes;
print-severity yes;
print-time yes;
};
category queries { bind_log; };
};
/etc/bind/named.conf后面添加：
include "/etc/bind/named.conf.log";修改文件用户：
chown bind:bind /var/log/named/bind.log原因是/etc/apparmor.d/usr.sbin.named这个文件中有:
/var/log/named/** rw,
/var/log/named/ rw,你也可以修改成你指定的目录。
