　　　　8.4查看密码策略:

mysql> show variables like '%password%';
+---------------------------------------+--------+
| Variable_name                         | Value  |
+---------------------------------------+--------+
| default_password_lifetime             | 0      |
| disconnect_on_expired_password        | ON     |
| log_builtin_as_identified_by_password | OFF    |
| mysql_native_password_proxy_users     | OFF    |
| old_passwords                         | 0      |
| report_password                       |        |
| sha256_password_proxy_users           | OFF    |
| validate_password_check_user_name     | OFF    |
| validate_password_dictionary_file     |        |
| validate_password_length              | 8      |
| validate_password_mixed_case_count    | 1      |
| validate_password_number_count        | 1      |
| validate_password_policy              | MEDIUM |
| validate_password_special_char_count  | 1      |
+---------------------------------------+--------+
14 rows in set (0.01 sec)

　　　　8.5如果不需要密码策略，添加my.cnf文件中添加如下配置禁用即可：

validate_password = off

　　　　8.6重新启动mysql服务使配置生效：

systemctl restart mysqld

MySQL使用

1、进入MySQL命令：

mysql -u 用户名 -p
例：

输入的命令行: mysql -u root -p (输入同样后会让你输入ySQL的密码)
2、在MySQL-Front中新建你要建的数据库，这时只是空数据库：

mysql>create database 数据库名字

例：

输入的命令行: mysql>create database blog; (新建一个名为blog的目标数据库)
3、使用创建的数据库：

mysql>use 数据库名字
例：

输入的命令行: mysql>use blog; (目标数据库名)
4、导入文件：

mysql>source 导入的文件名;
例：

输入的命令行：mysql>source blog.sql; (导入blog.sql文件)

5.exit 退出

测试 ECS

新建文件hello.js。

cd ~ 
touch hello.js

　　　　2.使用vim编辑器打开

yum install vim

vim hello.js

　　　　　　输入 i，进入编辑模式

　　　　　　使用Esc按钮，退出编辑模式，输入:wq，回车，保存文件内容并退出。

const http = require('http');

const hostname = '0.0.0.0';

const port = 80;

const server = http.createServer((req, res) => {

res.statusCode = 200;

res.setHeader('Content-Type', 'text/plain');

res.end('Hello World\n');

});

server.listen(port, hostname, () => {

console.log(`Server running at http://${hostname}:${port}/`);

});

　　　　3.运行

node ~/hello.js
