 您可以尝试添加 --skip-broken 选项来解决该问题
 您可以尝试执行：rpm -Va --nofiles --nodigest

缺少libmysqlclient.so.18，这玩艺不能自动下载？OH，原来是没配MYSQL的源，下载的时候没下载下来

到官网（https://dev.mysql.com/downloads/mysql/）下载mysql-community-libs-compat-8.0.30-1.el7.x86_64.rpm

具体下载哪个版本建议和你的mysql版本一致，聪明的程序员都知道，右边这个链接后面的版本是可以改的，https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-community-libs-compat-8.0.28-1.el7.x86_64.rpm

下载完成后，将其放入离线库中，并更新本地源或私有源

createrepo --update /yum/local
#需要执行一下更新操作，否则无法找到刚刚更新的包
yum makecache

测试安装

yum install keepalived

这回是真成功了
