系统升级次数多了，系统中经常保留了多个内核文件，下面的办法可以限制数量。
1、限制安装的内核数量，，比如2个
# grep limit /etc/yum.confinstallonly_limit=2
此时，如果要安装一个新的内核，必须删掉一个空闲的内核
# rpm -qa kernelkernel-2.6.32-431.11.2.el6.x86_64kernel-2.6.32-431.5.1.el6.x86_64# uname -rkernel-2.6.32-431.11.2.el6.x86_64# yum install kernel-2.6.32-431.el6.x86_64Loaded plugins: fastestmirrorLoading mirror speeds from cached hostfileSetting up Install ProcessResolving Dependencies–> Running transaction check—> Package kernel.x86_64 0:2.6.32-431.el6 will be installed–> Finished Dependency Resolution–> Running transaction check—> Package kernel.x86_64 0:2.6.32-431.5.1.el6 will be erased–> Finished Dependency ResolutionDependencies Resolved============================================================================================================================================================= PackageArchVersionRepositorySize=============================================================================================================================================================Installing: kernelx86_642.6.32-431.el6base28 MRemoving: kernelx86_642.6.32-431.5.1.el6@updates121 MTransaction Summary=============================================================================================================================================================Install1 Package(s)Remove1 Package(s)Total download size: 28 MIs this ok [y/N]:
2、限制保留的内核
yum install yum-utilspackage-cleanup –oldkernels –count=2
