对mysql数据库初始化过程中，会有如下报错信息：

 

1 2 3 4 5 6 7

[root@localhost scripts] # ./mysql_install_db --user=mysql FATAL ERROR: Could not find . /bin/my_print_defaults If you compiled from source , you need to run 'make install' to copy the software into the correct location ready for operation. If you are using a binary release, you must either be at the top level of the extracted archive, or pass the --basedir option pointing to that location.

 

按照报错信息，去mysql安装目录的bin目下查找是否有_print_defaults，在第一列的第七行有发现这个文件

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

看来其实不是没有这个文件，不是这个问题。

认真查看报错信息，可注意到那个路径是相对路径，是以mysql的安装目录为起始。

而初始化则是进去初始化脚本目录里运行脚本，而在这个目录下不会有./bin/my_print_defaults的。

所以回到安装目录以相对路径去执行初始化脚本。

[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql Installing MySQL system tables... OK Filling help tables... OK To start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: ./bin/mysqladmin -u root password 'new-password' ./bin/mysqladmin -u root -h localhost.localdomain password 'new-password' Alternatively you can run: ./bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default.  This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; ./bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd ./mysql-test ; perl mysql-test-run.pl Please report any problems with the ./bin/mysqlbug script! [root@localhost mysql]#

 

OK！初始化成功！

希望能对大家有帮助
