# ./bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
(4)设置环境变量
# vi /root/.bash_profile
在PATH=$PATH:$HOME/bin添加参数为：
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin:/usr/local/mysql/lib
#source /root/.bash_profile

------------------------------------------安全设置--------------------------------------
创建数据库：
create database 数据库名 default charset utf8 collate utf8_general_ci;
创建一个最小权限的用户test
create user 'test'@'%' IDENTIFIED by '123456';
grant select,insert,update,delete,create,drop,alter on 数据库名.* to 'test'@'%';
grant lock tables on 数据库名.* to 'test'@'%';
flush privileges;
修改root用户名和密码，限制远程访问
update mysql.user set user="admin" where user="root";
flush privileges;
update user set host='localhost' where user='admin';
flush privileges;//只允许root在本机登录
SET PASSWORD FOR 'admin'@'localhost' = PASSWORD('复杂的密码');
flush privileges;
