1、使用源码安装MySQL 5.7
（1）安装开发工具和开发包
[root@bogon ~]#yum install make gcc gcc-c++ cmake bison-devel ncurses-devel -y
[root@bogon ~]#yum install libaio libaio-devel openssl-devel -y
[root@bogon ~]#yum install perl-Data-Dumper -y
[root@bogon ~]#yum install net-tools -y （2）安装MySQL
（3）解压
[root@bogon~mysql-5.7.14]# tar xf mysql-boost-5.7.14.tar.gz -C /usr/local/src/（4）检查
[root@bogon ~ mysql-5.7.14]# cd /usr/local/src/mysql-5.7.14/
[root@bogon ~ mysql-5.7.14]# cmake . -DWITH_BOOST=/usr/local/src/mysql-5.7.14/boost/boost_1_59_0/（5）编译
[root@bogon ~ mysql-5.7.14]# make
（6）安装
[root@bogon ~ mysql-5.7.14]# make install（7）创建用户和组
[root@bogon ~]# useradd -r -u 333 -g 36 -c 'MySQL Server' mysql
[root@bogon ~]# groupadd -r -g 333 mysql（8）初始化
[root@bogon local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/date（9）提供配置文件和脚本
#提供配置文件
[root@bogon ~]# \cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
修改：datadir
[root@bogon ~]# vim /etc/my.cnf
datadir = /usr/local/mysql/data
#提供服务脚本
[root@bogon ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld（10）启动服务
#添加到系统服务
[root@bogon ~]# chkconfig --add mysqld
#启动服务
[root@bogon ~]# systemctl start mysqld
#开机自启动
[root@bogon ~]# chkconfig mysqld on（11）添加环境变量
#添加环境变量
[root@bogon ~]# vim /etc/profile.d/mysql.sh

mysql> 2、创建数据库school，字符集为utf8
mysql> create database if not exists school character set utf8;
Query OK, 1 row affected (0.00 sec)
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| school |
| sys |
+--------------------+
5 rows in set (0.00 sec)3、在school数据库中创建Student和Score表
（1）应用school数据库
mysql> use school;
Database changed
mysql> select database();
+------------+
| database() |
+------------+
| school |
+------------+
1 row in set (0.00 sec)（2）创建student表
mysql> create table student(
-> ID int(10) primary key unique auto_increment comment '学号',
-> Name varchar(20) not null comment '姓名',
-> Sex enum('M','F') comment '性别',
-> Birth year comment '出生年份',
-> Department varchar(20) not null comment '院系',
-> Address varchar(50) comment '家庭住址'
-> )comment = '学生信息表';
Query OK, 0 rows affected (0.01 sec)

mysql> create table score(
-> ID int(10) primary key unique auto_increment comment '编号',
-> Stu_id int(10) not null comment '学号',
-> C_name varchar(10) comment '课程名',
-> Grade int(10) comment '分数'
-> )comment = '成绩信息表';
Query OK, 0 rows affected (0.01 sec)（4）查看school中创建的表
（5）查看表的结构
4、授权用户tom，密码mysql，能够从任何地方登录并管理数据库school
（1）关闭mysql服务
[root@bogon ~]# systemctl stop mysqld
（2）修改配置文件
vim /etc/my.cnf
添加： validate_password=off
（3）重新启动mysqld服务
