1.安装MySQL
解压：
root@13 \~# tar -xvf mysql-8.0.33-linux-glibc2.12-x86_64.tar
mysql-test-8.0.33-linux-glibc2.12-x86_64.tar.xz
mysql-8.0.33-linux-glibc2.12-x86_64.tar.xz
mysql-router-8.0.33-linux-glibc2.12-x86_64.tar.xz
继续解压：
root@13 \~# tar -xf mysql-8.0.33-linux-glibc2.12-x86_64.tar.gz
2.进入解压后目录：
root@13 \~# cd mysql-8.0.33-linux-glibc2.12-x86_64/
root@13 mysql-8.0.33-linux-glibc2.12-x86_64#
root@13 mysql-8.0.33-linux-glibc2.12-x86_64# ls
bin docs include lib LICENSE man README share support-files
root@13 mysql-8.0.33-linux-glibc2.12-x86_64#
3.配置文件：
root@13 mysql-8.0.33-linux-glibc2.12-x86_64# vim support-files/mysql.server
4.移动文件
root@13 \~# cp -r mysql-8.0.33-linux-glibc2.12-x86_64/ /usr/local/mysql/
5.创建用户：
useradd -r -s /sbin/nologin mysql
6.创建目录：
root@13 \~# cd /usr/local/mysql
root@13 mysql# mkdir mysql-files
7.修改新创建的目录mysql-files权限：
root@13 mysql# chown mysql:mysql /usr/local/mysql/mysql-files/
root@13 mysql# chmod 750 /usr/local/mysql/mysql-files/
- 初始化数据库，找初始密码
root@13 \~# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql/

9.安全加密：
root@13 \~# /usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
10.其他配置：
方便启动：
root@13 \~# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql8
11.启服务：
root@13 mysql# service mysql8 start
Starting MySQL... SUCCESS!
12.创建用户：
create user '用户名'@'%' identified by '密码'
mysql> create user 'hh'@'%' identified by '1Mysql@1'
-> ;
Query OK, 0 rows affected (0.29 sec)
mysql> exit
Bye
13.登录hh用户，查看全部表：
root@15 \~# mysql -u hh -p
Enter password:1Mysql@1
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| performance_schema |
+--------------------+
2 rows in set (0.03 sec)
mysql> exit
Bye
14.退出hh用户，进入root给hh用户添加权限：
root@15 \~# mysql -u root -p
mysql> grant all on *.* to "hh";
Query OK, 0 rows affected (0.06 sec)
mysql> exit
15.进入hh用户，查看全部表：
root@15 \~# mysql -u hh -p
