    安装 nvm

    1. 直接使用git将源码克隆到本地的~/.nvm目录下,并检查最新版本。
      1. git clone https://github.com/cnpm/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`
    2. 激活NVM。

      1. echo ". ~/.nvm/nvm.sh" >> /etc/profile
    3. 直接使用git将源码克隆到本地的~/.nvm目录下,并检查最新版本。

    4. 激活NVM。

      1. echo ". ~/.nvm/nvm.sh" >> /etc/profile
      2. source /etc/profile
    5. 列出Node.js的所有版本。

      1. nvm list-remote
    6. 安装多个Node.js版本。

      1. nvm install v6.9.5
      2. nvm install v7.4.0
    7. 运行 nvm ls 查看已安装Node.js版本,当前使用的版本为v6.9.5。返回结果如下所示。

      1. [root@iZXXXXZ .nvm]# nvm ls
      2. v6.9.5
      3. -> v7.4.0
      4. system
      5. stable -> 7.4 (-> v7.4.0) (default)
      6. unstable -> 6.9 (-> v6.9.5) (default)
    8. 运行 nvm use v7.4.0 切换Node.js版本至v7.4.0。返回结果如下所示。

      1. [root@iZXXXXZ .nvm]# nvm use v7.4.0
      2. Now using node v7.4.0

    完毕!

        5.启动MySQL服务

    systemctl start mysqld
        6.查看MySQL启动状态
    systemctl status mysqld
    [root@izuf6dt5e7ronm1meixuipz ~]# systemctl status mysqld
    ● mysqld.service - MySQL Server
       Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

    [root@izuf6dt5e7ronm1meixuipz ~]# 

        7.设置MySQL开机启动

    systemctl enable mysqld
    systemctl daemon-reload
        8.修改root密码
          8.1 查看默认密码
     grep 'temporary password' /var/log/mysqld.log
    [root@izuf6dt5e7ronm1meixuipz ~]#  grep 'temporary password' /var/log/mysqld.log
    2018-07-17T02:33:24.001978Z 1 [Note] A temporary password is generated for root@localhost: kbY0Xw3gf>)e

          8.2 修改密码(密码输入上一步的默认密码)

    [root@izuf6dt5e7ronm1meixuipz ~]# mysql -uroot -p

    Enter password: 

    Welcome to the MySQL monitor.  Commands end with ; or g.

    Your MySQL connection id is 3

    Server version: 5.7.22

    Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

     

    mysql> 

    mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '密码'; 
    Query OK, 0 rows affected (0.00 sec)
    
    
    mysql> set password for 'root'@'localhost'=password('密码'); 
        8.3密码不符合规范报错:

            mysql5.7默认安装了密码安全检查插件(validate_password),默认密码检查策略要求密码必须包含:大小写字母、数字和特殊符号,并且长度不能少于8位。否则会提示ERROR 1819 (HY000)

    ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

        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
    ');
    
    });
    
    server.listen(port, hostname, () => {
    
    console.log(`Server running at http://${hostname}:${port}/`);
    
    });

        3.运行

    node ~/hello.js
