1.下载软件之后上传到服务器,可通过xftp或者其他工具

2.解压压缩包到指定文件夹,可随意指定

tar -xvf Percona-Server-5.7.23-23-r500fcf5-el7-x86_64-bundle.tar -C /home/software/mysql/

3.卸载废弃的依赖包

yum remove mariadb*

4.进入到解压目录进行rpm安装,注意顺序不能乱

cd /home/software/mysql
rpm -ivh Percona-Server-57-debuginfo-5.7.23-23.1.el7.x86_64.rpm
rpm -ivh Percona-Server-shared-compat-57-5.7.23-23.1.el7.x86_64.rpm
rpm -ivh Percona-Server-shared-57-5.7.23-23.1.el7.x86_64.rpm
rpm -ivh Percona-Server-client-57-5.7.23-23.1.el7.x86_64.rpm
rpm -ivh Percona-Server-server-57-5.7.23-23.1.el7.x86_64.rpm

5.启动MySQL服务

service mysqld start

6.修改默认密码

cat /var/log/mysqld.log | grep "A temporary password" | awk -F " " '{print$11}'

mysql -u root -p

  • 首先,修改validate_password_policy参数的值
    mysql> set global validate_password_policy=0;
  • 再修改密码的长度
    mysql> set global validate_password_length=1;

ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
