第一次启动MySQL时报错

[root@localhost~]#/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql

Installing MySQL system tables...

ERROR: 1  Can't create/write to file '/tmp/#sql_2b11_0.MYI' (Errcode: 13)

120807 17:40:27 [ERROR] Aborting

120807 17:40:27 [Note] /usr/local/webserver/mysql/libexec/mysqld: Shutdown complete

Installation of system tables failed!  Examine the logs in

/data0/mysql/3306/data for more information.

You can try to start the mysqld daemon with:

shell> /usr/local/webserver/mysql/libexec/mysqld --skip-grant &

and use the command line tool /usr/local/webserver/mysql/bin/mysql

to connect to the mysql database and look at the grant tables:

shell> /usr/local/webserver/mysql/bin/mysql -u root mysql

mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log

gives you a log in /data0/mysql/3306/data that may be helpful.

Please consult the MySQL manual section

'Problems running mysql_install_db', and the manual section that

describes problems on your OS.  Another information source are the

MySQL email archives available at http://lists.mysql.com/.

Please check all of the above before mailing us!  And remember, if

you do mail us, you MUST use the /usr/local/webserver/mysql/scripts/mysqlbug script!

[root@localhost ~]#

解决方法：

/tmp目录没有写入权限，使用chmod 777 /tmp即可
