Centos7中安装Mysql8并修改密码策略并远程连接
安装Mysql8
1、yum仓库下载MySQL:
yum localinstall https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
2、yum安装MySQL:
yum install mysql-community-server
3、启动MySQL服务:
service mysqld start
4、检查MySQL服务状态:
service mysqld status
5、查看初始密码(如无内容直接跳过):
grep 'temporary password' /var/log/mysqld.log
修改密码策略(在mysql中执行下面命令)
set global validate_password.policy=0;
set global validate_password.length=4;
set global validate_password.check_user_name=OFF;
set global validate_password.number_count=0;
set global validate_password.special_char_count=0;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';
查看当前密码策略(没有修改初始密码时不能查看)
SHOW VARIABLES LIKE 'validate_password%';
远程连接:
执行命令为:mysql -u root -p
使用mysql数据库:use mysql;
更改 host 的默认配置
update user set host='%' where user='root';
刷新
flush privileges;
