Share a script that automates the configuration of xinetd and rsync

Installing the configuration xinetd Super daemon and rsync is very simple. In the study, I wrote an automated deployment of the script, after testing can be used, has done the basic optimization, although simple, but still want to record, for everyone to reference, look forward to you can help me to guide twos.

The script is as follows:

#! /bin/bash# determine whether to download the installation xinetd service  rpm -qa |grep xinetd >/dev/null# if not installed if [ [ $? == 1 ]] thenyum install xinetd -yif [[ $? == 1 ]];thenecho  "xinetd download failed! Check to see if your network is unblocked. "exitfiecho " XINETD installed successfully! "fi# See if Rsync installs rpm -qa |grep rsync >/dev/null# if not installed if [[ $? == 1  ]]thenyum install rsync -yif [[ $? == 1 ]];thenecho  " rsync Download failed!
