wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm
rpm -ivh mysql57-community-release-el7-8.noarch.rpm
yum -y install mysql-server
默认配置文件路径:
配置文件:/etc/my.cnf
日志文件:/var/log/var/log/mysqld.log
服务启动脚本:/usr/lib/systemd/system/mysqld.service
socket文件:/var/run/mysqld/mysqld.pid
启动mysql服务
service mysqld restart (systemctl start mysqld.service)
查看mysql服务状态
service mysqld status (systemctl status mysqld.service)
重置密码
grep "password" /var/log/mysqld.log
登录成功以后修改密码
默认是有对密码长度的限制的,所以设置的密码太简单的话,是通不过的
1 mysql> SHOW VARIABLES LIKE ‘validate_password%‘; 2 +--------------------------------------+--------+ 3 | Variable_name | Value | 4 +--------------------------------------+--------+ 5 | validate_password_check_user_name | OFF | 6 | validate_password_dictionary_file | | 7 | validate_password_length | 8 | 8 | validate_password_mixed_case_count | 1 | 9 | validate_password_number_count | 1 | 10 | validate_password_policy | MEDIUM | 11 | validate_password_special_char_count | 1 | 12 +--------------------------------------+--------+ 13 7 rows in set (0.01 sec) 14 15 mysql> set global validate_password_policy=0; 16 Query OK, 0 rows affected (0.00 sec) 17 18 mysql> set global validate_password_length=1; 19 Query OK, 0 rows affected (0.01 sec)
通过15行和18行的设置,就可以把密码设置成诸如root之类的简单密码了
修改完密码刷新权限
flush privileges;
把在所有数据库的所有表的所有权限赋值给位于所有IP地址的root用户
grant all on *.* to ‘root‘@‘%‘ identified by ‘root‘ with grant option;
但此时还有一个问题,就是因为安装了Yum Repository,以后每次yum操作都会自动更新,需要把这个卸载掉:
yum -y remove mysql57-community-release-el7-8.noarch
