在Linux操作系统上配置DNS服务器地日志

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
