前言
这几天，在测试程序中要用mysql client api 去数据库插入记录和查询记录。
好久不用mysql client api, 没有封装好的存货。只能用api直接干活。
前天闲下来了，将mysql client api的使用封装成类，对执行sql语句的操作封装了成员函数，实现库的建立，表的建立，use database, 记录的增删改查. 等下次再用到，就直接用这个类干活了。
实验环境
debian8.8 + mysql5.5.60-0+deb8u1
前置任务
如果连接的不是本地mysql数据库，需要在数据库改用户权限，使远程访问数据库成为可能。
这活，如果是在工作中，已经由运维人员搞好了。
如果是自己做实验，这步要自己做。
# 在debian8.8中安装mysql
aptitude install mysql-server mysql-client
# 登陆mysql客户端 ，连接本地数据库
mysql -h 127.0.0.1 -u root -p
# 如果不是回环ip访问, 需要在配置文件中绑定允许访问的客户端ip
vi /etc/mysql/my.cnf
# bind-address = 127.0.0.1
# ref https://dev.mysql.com/doc/refman/8.0/en/server-options.html
bind-address = *
# 重启mysql服务
/etc/init.d/mysql restart
# 修改mysql配置之后, 就可以用回环地址或者本地IP地址登陆msyql客户端工具了
mysql -h 192.168.11.140 -u root -p
建立供远程访问的mysql用户
mysql> select host,user,password from mysql.user;
mysql口令的用户长度是定长的
mysql> create user remote_user identified by password '12345678901234567890123456789012345678901';
Query OK, 0 rows affected (0.00 sec)
给刚建立远程用户设置所有数据库操作的权限.设置完后，就可以用本地活远程用服务器的IP来登陆mysql了
实际的工作数据库，运维人员都设置好了，我们不管.
grant all privileges on *.* to remote_user identified by '12345678901234567890123456789012345678901';
其他一些可能用到的mysql客户端的命令. 其实到了这步，就可以在windows上搞个图形化的数据库工具来做实验了.
mysql> SHOW DATABASES; //显示数据库
mysql> USE my_db //进入数据库
mysql> SHOW TABLES; //显示表
mysql> DESCRIBE mytable; //显示表结构
mysql> CREATE DATABASE abccs; //创建一个数据库
mysql> select version(); // 显示数据库版本
