服务器重装，环境配置正常，domain没有变动，启动AdminServer失败。

==============================================
经过查阅资料了解到，原来当机器存在多个网卡时，服务器可能会无法确认选择正确的适配器，而我的机器由于有虚拟机和无线网卡，确实存在多个适配器，这个解决办法是修改/etc/hosts文件
127.0.0.1 localhost.localdomain localhost 【机器名】【IP】【域名】
添加后发现问题依旧，后经测试发现，由于重装后未给用户 /etc/hosts的读权限，导致无法识别DNS。
增加权限后，问题解决~！
