使用rpm(Red Hat Package Manager)或yum(Yellowdog Updater / Modifier)

1)RPM

rpm -qa > to_be_installed; while read -r package; do yum -y install "$package"; done < to_be_installed

2)YUM

yum list installed | awk '{print $1}' > to_be_installed; while read -r line; do yum -y install "$line"; done < to_be_installed

希望这能为您提供一些如何做到这一点的想法.
