1.下载地址:https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.30-winx64.zip

2.安装

• 解压：解压到D盘，改名为：mysql-5.7.30

• 设置环境变量

  • 系统—>高级系统设置—>环境变量—>系统变量
    
    新建 变量名：MYSQL_HOME 值：D:\mysql-5.7.30
  • Path最后添加：;%MYSQL_HOME%\bin

• mysql-5.7.30下创建my.ini，内容如下：

  [mysqld]
  #端口号
  port = 3306
  #mysql-5.7.30-winx64的路径
  basedir=D:\mysql-5.7.30
  #mysql-5.7.30-winx64的路径+\data
  datadir=D:\mysql-5.7.30\data
  #最大连接数
  max_connections=200
  #编码
  character-set-server=utf8
  default-storage-engine=INNODB
  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
  skip-grant-tables  #无需密码验证
  [mysql]
  #编码
  default-character-set=utf8
  

• 管理员运行cmd

  • mysqld -install 成功：Service successfully installed
  • mysqld –initialize 成功：没有提示
  • net start mysql 启动

• 修改密码

  • mysql -u root -p 回车
  • use mysql
  • update user set authentication_string=password(“123456”) where user=“root”
  • net stop mysql 停止服务器

• 删除my.ini 中 skip-grant-tables

• net start mysql 启动

• mysql -u root -p 回车输入密码

• alter user user() identified by “123456”;

3. Ubuntu16.04 安装MySQL ODBC驱动

• 下载：https://cdn.mysql.com/archives/mysql-connector-odbc-5.2/mysql-connector-odbc-5.2.7-linux-glibc2.5-x86-64bit.tar.gz

• 安装

  • 解压到 /use/local 命名为：mysql-connector-odbc-5.2.7
  • cd /usr/local/mysql-connector-odbc-5.2.7/bin
  • sudo ./myodbc-installer -d -a -n “MYSQL” -t “DRIVER=/usr/lib/libmyodbc5a.so;SETUP=/usr/lib/libmyodbc5a.so”
  • sudo cp -r /usr/local/mysql-connector-odbc-5.2.7/lib/. /usr/lib
  • sudo cp -r /usr/local/mysql-connector-odbc-5.2.7/lib/. /usr/lib64

• 配置ODBC驱动

  • sudo vi /etc/odbcinst.ini (与执行myodbc-installer 冲突)
    
    [MYSQL]
    
    Description=ODBC for MySQL
    
    Driver=/usr/lib/libmyodbc5a.so
    
    SETUP=/usr/lib/libmyodbc5a.so
    
    Driver64=/usr/lib64/libmyodbc5a.so
    
    SETUP64=/usr/lib64/libmyodbc5a.so
    
    FileUsage=1

• 配置访问数据库信息

  • 创建echat 数据库
  • sudo gedit /etc/odbc.ini
    
    [echat]
    
    Driver = /usr/lib/libmyodbc5a.so
    
    SERVER = 192.168.2.111
    
    PORT = 3306
    
    DATABASE = echat
    
    USER = root
    
    PASSWORD = 123456
    
    OPTION = 67108864
    
    SocketBufferSize = 4096
    
    FetchBufferSize = 100
    
    CHARSET = UTF8

• 测试：isql -v echat
