有些时候，我们在对系统进行更新操作时，又不需要对某些软件包进行升级操作，要把该包锁定在某个特定版本下。比如mysql-server，为了避免更新遇到不可预知的错误，禁止对该包进行升级。
那么该如何锁定包在特定版本下呢？文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/
在上一篇《CentOS / RHEL 防止Kernel升级》，该方法也可以实现。文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/
下面我来介绍另一种方法。使用yum versionlock 命令来锁定版本。文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/
1. 安装文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/
# yum install yum-plugin-versionlock.noarch
2. 添加锁定包文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/

使用该指令就可以避免误升级软件包到最新版本。特别是在生产环境下的软件包，版本的更新可以有些配置参数不兼容到服务停止，从而影响正常的访问。文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/ 文章源自运维生存时间-https://www.ttlsa.com/linux/centos-rhel-lock-package-version-at-a-particular-version/
