CentOS Start SendMail Service long time Problem solving method

The host name is not set up to cause the following 2 issues:

1, CentOS start time sendmail, sm-client wait long.

2, SendMail Error

Workaround: Correct the hostname and restart it.

two places need to be modified : One is/etc/sysconfig/network and the other is/etc/hosts, and it is not enough to modify one place at a.

Switch to the root user under the character interface (CentOS uses ALT+CTAL+F6).

/etc/sysconfig/network
Open the file with any of your favorite editors, with a line of Hostname=localhost.localdomain (if default), and modify Localhost.localdomain to your hostname.

Like Hostname=yes81.localdomain.

/etc/hosts
Open the file, there will be a line 127.0.0.1 localhost.localdomain localhost. Where 127.0.0.1 is the local loop address, Localhost.localdomain is the hostname (hostname), which is what you want to modify. LocalHost is the alias of the hostname, which appears under the Konsole prompt. Change the second item to your hostname, and the third option is optional.

I modified to: 127.0.0.1 yes81.localdomain localhost

After modifying the above two documents, it will not be effective immediately. If you want to take effect immediately, you can use hostname your-hostname for temporary modification, it just temporarily modifies the hostname, the system restarts will be restored as is. However, modifying the above two files is permanent, and rebooting the system will give you a new host name.

Finally, check the hostname uname-n after rebooting.

Reboot, basically without waiting. Launch directly into the wait screen.
