在做LAMP实验的过程中，配置MySQL，提示如下错误：
[root@localhost /]# /usr/local/mysql/bin/mysqld_multi --config-file=/usr/local/mysql/etc/mysqld_multi.cnf start 0,1,2
WARNING: my_print_defaults command not found.
Please make sure you have this command available and
in your path. The command is available from the latest
MySQL distribution.
ABORT: Can't find command 'my_print_defaults'.
This command is available from the latest MySQL
distribution. Please make sure you have the command
in your PATH.
原因是之前实验装了多个版本的MySQL，解决办法是输入如下命令：
[root@localhost /]# export PATH=/usr/local/mysql/bin:$PATH
将/usr/local/mysql/bin加到$PATH环境变量里
