mysql中使用tee实现类似oracle spool功能

本文主要是介绍mysql中使用tee实现类似oracle spool功能，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

  在mysql中我们可以通过tee来实现类似oracle 中spool的功能，实现方式有如下三种：

1.在/etc/my.cnf中的[client]部分加入类似如下内容

tee =/root/tee.log

##这样在新的客户端登录数据库时就会记录他所有的操作

 mysql -uroot -p -S /tmp/mysql3306.sock
Logging to file '/root/tee.log' <span style="color:#ff0000;"> >>已经生成了日志</span>
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1

执行show databases;操作后查看tee.log

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| shao               |
| test               |
+--------------------+
5 rows in set (0.00 sec)

vi /root/tee.log

vi /root/tee.log

| performance_schema |
| shao               |
| test               |
+--------------------+
5 rows in set (0.00 sec)

2.在登录的时候指定--tee参数

mysql -uroot -p -S /tmp/mysql3306.sock --tee=/root/tee.log
Logging to file '/root/tee.log'  <span style="color:#ff0000;">>>生成日志</span>
Enter password:

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| shao               |
| test               |
+--------------------+
5 rows in set (0.00 sec)

3.登录mysql后执行tee命令

mysql> tee /root/tee.log
Logging to file '/root/tee.log'
mysql> show variables like 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)mysql> 

查看日志

 vi tee.log 
mysql> show variables like 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)
