服务器的安全升级却是必须的，所以，下面介绍一个yum插件：yum-plugin-security 来进行安全性升级。
$ sudo yum install yum-security 2. 如果是red hat 6，yum-plugin-security现在增加了了一个updateinfo命令。这个命令用来查看可安全更新的软件列表(只查看，不更新)，输入下面的命令： 复制代码 代码如下:$ sudo yum updateinfo list security
输出： 复制代码 代码如下:Loaded plugins: security, versionlock
CVE-2013-1619 security gnutls-2.8.5-10.el6_4.1.x86_64 CVE-2013-1493 security java-1.6.0-openjdk-1:1.6.0.0-1.57.1.11.9.el6_4.x86_64 CVE-2013-0809 security java-1.6.0-openjdk-1:1.6.0.0-1.57.1.11.9.el6_4.x86_64 CVE-2013-0268 security kernel-uek-2.6.39-400.17.2.el6uek.x86_64 CVE-2013-0268 security kernel-uek-firmware-2.6.39-400.17.2.el6uek.noarch CVE-2012-4929 security openssl-1.0.0-27.el6_4.2.x86_64 CVE-2013-0166 security openssl-1.0.0-27.el6_4.2.x86_64 CVE-2013-0169 security openssl-1.0.0-27.el6_4.2.x86_64 updateinfo list done
对于 red hat 或者 centos 5.x 版本而言，则使用下面的命令来查看可安全更新的软件列表： 复制代码 代码如下:$ sudo yum list updates --security
升级需要安全更新的软件包，输入命令： 复制代码 代码如下:$ sudo yum update --security
输出如下： 复制代码 代码如下:Loaded plugins: security, versionlock
