直奔主题!!!
每次sendmail启动特别慢,查看日志
[root@drbd01 ~]# tail -f /var/log/maillog May 22 14:25:23 drbd01 sendmail[5731]: My unqualified host name (drbd01) unknown; sleeping for retry May 22 14:26:23 drbd01 sendmail[5731]: unable to qualify my own domain name (drbd01) -- using short name
修改hosts文件
vim /etc/hosts 127.0.0.1 localhost.localdomain localhost drbd0
将当前的主机名drbd0添加到hosts文件中!
重启噌噌的.
