本文主要是介绍FreeIPA安装后Named service无法启动 - RHEL6.5，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
在RHEL6.5的环境下，安装FreeIPA后Named service无法启动。错误如下:
Configuring DNS (named)[1/9]: adding DNS container[2/9]: setting up our zone[3/9]: setting up reverse zone[4/9]: setting up our own record[5/9]: setting up kerberos principal[6/9]: setting up named.conf[7/9]: restarting named
named service failed to start[8/9]: configuring named to start on boot[9/9]: changing resolv.conf to point to ourselves
Done configuring DNS (named).
检查/var/log/message， 显示如下：
Oct 24 19:15:46 ipa named-sdb[10721]: Failed to parse the principal name DNS/ipa.xionghuilin.com (Configuration file does not specify default realm)
Oct 24 19:15:46 ipa named-sdb[10721]: loading configuration: failure
Oct 24 19:15:46 ipa named-sdb[10721]: exiting (due to fatal error)
参考这个链接, 这个问题的原因可能是chroot导致的某些文件无法正确读取， 标准的解决方案是Howto/FreeIPA with integrated BIND inside chroot，简单的解决方案是卸载bind-chroot软件包。
