安装 server 还可能报错:
rpm -ivh mysql-community-server-5.7.39-1.el7.x86_64.rpm warning: mysql-community-server-5.7.39-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY error: Failed dependencies: net-tools is needed by mysql-community-server-5.7.39-1.el7.x86_64
执行以下命令安装 net-tools 解决:
yum install net-tools -y
systemctl start mysqld
cat /var/log/mysqld.log | grep 'password is generated'
