我要评论
我要评论这篇文章主要介绍了在CentOS系统中使用yum命令升级插件的方法,即yum-plugin-security命令的相关的使用来安全升级插件,需要的朋友可以参考下
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。
1.一般系统默认安装了yum-plugin-security，如果没有，则输入命令安装yum-plugin-security ：
$ 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

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
