服務器的安全升級卻是必須的，所以，下面介紹一個yum插件：yum-plugin-security 來進行安全性升級。

1.一般系統默認安裝了yum-plugin-security，如果沒有，則輸入命令安裝yum-plugin-security ：

$ sudo yum install yum-security

2. 如果是red hat 6，yum-plugin-security現在增加了了一個updateinfo命令。這個命令用來查看可安全更新的軟件列表(只查看，不更新)，輸入下面的命令：

復制代碼

代碼如下:

$ sudo yum updateinfo list security

輸出：

復制代碼

代碼如下:

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-2013-0169 security openssl-1.0.0-27.el6_4.2.x86_64
updateinfo list done

對于 red hat 或者 centos 5.x 版本而言，則使用下面的命令來查看可安全更新的軟件列表：

復制代碼

代碼如下:

$ sudo yum list updates --security

升級需要安全更新的軟件包，輸入命令：

復制代碼

代碼如下:

$ sudo yum update --security

輸出如下：
