安装mysql
 
1）rpm安装mysql5.7
 
mysql-community-devel-5.7.12-1.el6.x86_64.rpm
 
mysql-community-libs-5.7.12-1.el6.x86_64.rpm
 
mysql-community-test-5.7.12-1.el6.x86_64.rpm
 
mysql-community-client-5.7.12-1.el6.x86_64.rpm
 
mysql-community-common-5.7.12-1.el6.x86_64.rpm
 
mysql-community-server-5.7.12-1.el6.x86_64.rpm
 
如果有冲突的安装，先卸载，如：
 
rpm -e mysql-libs-5.1.66-2.el6_3.x86_64 --nodeps
 
2）启动mysql
 
service mysqld start
 
3）修改mysql 的root用户密码
 
如果在/etc/my.cnf修改了socket文件位置，则也应该同时修改[mysql]的socket文件位置；
 
#mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
 
#mysql -u root mysql
 
//mysql5.6
 
// mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
 
//mysql5.7
 
mysql> UPDATE user SET authentication_string=PASSWORD('aaa123') where USER='root';
 
//使用desc user查看表字段描述
 
mysql> FLUSH PRIVILEGES;
 
mysql> quit
 
重新执行：
 
Mysql>SET PASSWORD = PASSWORD('123456');
 
或者
 
Mysql>alter user root@localhost identified by ‘aaAA1234!@#$’;
 
*rpm安装，basedir为/usr
 
4）root用户登录mysql
 
[root@vm1 ~]# mysql -uroot -p
