• 将my_default.cnf上传至support-files文件夹中

cp my_default.cnf /usr/local/mysql/support-files

• 创建data文件夹

cd usr/local/mysqlmkdir data 

• 注册和初始化MYSQL服务

bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

• 复制上述的my_default.cnf和mysql.server配置文件到etc目录，它这里提示是否覆盖，输入Y覆盖

cp -a /usr/local/mysql/support-files/my_default.cnf /etc/my.cnfcp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

• 启动MYSQL服务

cd bin/./mysql_safe --user=mysql/etc/init.d/mysqld restart

• 连接至MYSQL，默认没有密码，直接回车后连接至MYSQL

./mysql -u root -p

• 修改MYSQL的root密码

 set password = password('123456');

• 修改可远程访问

 update user set host = '%' where user = 'root';

• 重启MYSQL服务

 /etc/init.d/mysqld restart
