在Linux环境下，也提供了广泛流行的BIND服务器，它是构建DNS服务器最常用的服务器软件。介绍BIND的安装的文章现在很多，现在我们就一起来谈一下维护的话题。
我们如何才能够了解DNS服务器的运行情况下呢，它忙不忙、负载大不大?这一切，对于系统管理员而言，是比较重要的。
# touch /var/named/chroot/var/named/named.log
# chown named.named /var/named/chroot/var/named/named.log
# chmod 755 /var/named/chroot/var/named/named.log
# service named restart
并且确保 selinux是关闭状态(查看/etc/sysconfig/selinux配置信息)
然后查看采集到的/var/named/chroot/var/named/named.log是否存在故障信息
#LOG 配置信息
logging {
channel default_syslog { syslog local2; severity error; };
channel audit_log {
file "named.log" versions 3 size 20m;
severity info;
print-time yes;
print-category yes;
};
category default { audit_log; };
category general { audit_log; };
category security { audit_log; default_syslog; };
category config { default_syslog; };
category resolver { audit_log; };
category xfer-in { audit_log; };
category xfer-out { audit_log; };
