如何在VPS上设置'hostname fqdn'

我最近买了一台安装有DirectAdmin的vps服务器。一切工作正常，但我不能发送电子邮件。的管理向导的消息系统发出了这样的通知：如何在VPS上设置'hostname fqdn'

Cannot find your hostname using the command '/bin/hostname --fqdn'. Please check this >command to ensure it works properly. If you get the error: hostname: Name or service not known

Check your /etc/resolv.conf and try setting it to use 127.0.0.1Unable to resolve your >hostname, . This will cause major issues when sending email.

Solution:

Create an A record for your hostname (.) in your DNS control panel. Point the hostname to >your server's main IP address. Also check /etc/hosts to ensure that the server ip is >correctly set.

我的/ etc/hosts文件包含此：

# Do not remove the following line, or various programs 
# that require network functionality will fail. 
127.0.0.1 localhost.localdomain localhost 
127.0.1.1 srvubu100.screweb.com srvubu100  ::1  localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 

178.162.145.82  srv771.screweb.com 
178.162.145.82  srv771.bitcommand.com 
178.162.145.82  server1.novinhost.net

你应该使用脚本/usr/local/directadmin/scripts/hostname.sh这样设置主机名：

/usr/local/directadmin/scripts/hostname.sh host.yourdomain.com

那么你应该编辑你的/etc/hosts文件，并保持这样：

127.0.0.1 localhost.localdomain localhost 
::1 localhost ip6-localhost 

178.162.145.82 host.yourdomain.com

然后重新启动您的exim（service exim restart），它应该可以正常工作。
