[系统运维]MySQL 客户端安装(centos)

yum安装客户端，依次执行以下命令

yum -y install http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql
yum install -y mysql-server
mysql -uroot -h 127.0.0.1 -p   # 密码为：root

问题总结

warning: /var/cache/yum/x86_64/7/mysql57-community/packages/mysql-community-libs-5.7.37-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql


The GPG keys listed for the "MySQL 5.7 Community Server" repository are already installed but they are not correct for this package.
Check that the correct key URLs are configured for this repository.


 Failing package is: mysql-community-libs-5.7.37-1.el7.x86_64
 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

原因

GPG对于包的源key的验证没有通过

解决办法：绕过检验 --nogpgcheck

yum install mysql-community-server --nogpgcheck
