问题一:Centos7在安装Mysql依赖(libs)或客户端(client)时失败

warning: mysql-community-libs-8.0.28-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY

error: Failed dependencies:

   mariadb-libs is obsoleted by mysql-community-libs-8.0.28-1.el7.x86_64

解决方案

• 先卸载mysql-libs
  
• 再执行安装
  

# 先卸载mysql-libs

yum remove mysql-libs

# 再执行安装

rpm -ivh mysql-community-libs-8.0.28-1.el7.x86_64.rpm

问题二:Centos7在安装Mysql服务器(server)时失败

warning: mysql-community-server-8.0.28-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY

error: Failed dependencies:

   mysql-community-icu-data-files =8.0.28-1.el7 is needed by mysql-community-server-8.0.28-1.el7.x86_64

解决方案

• 解决的方法就是在rpm 语句后面加上 --nodeps --force，安装时忽略依赖关系
  

# 在rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm 添加参数--force --nodeps

rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm --force--nodeps
