今天我升級MYSQL到5.1的時(shí)候遇到的。寫出來共享以下，供大家參考。

1、

[root@localhost mysql]# scripts/mysql_install_db

Neither host 'localhost.localdomain' nor 'localhost' could be looked up with

/resolveip

Please configure the 'hostname' command to return a correct

hostname.

If you want to solve this at a later stage, restart this script

with the --force option

這個(gè)主要是修改/etc/hosts文件

echo "127.0.0.1 localhost.localdomain localhost" >> /etc/hosts

然后再初始化數(shù)據(jù)，如果還是同樣的錯(cuò)誤，那就直接加--force開關(guān)。

我今天碰到的就是這個(gè)情況。

[root@localhost mysql]# scripts/mysql_install_db --force

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:

/usr/local/mysql//bin/mysqladmin -u root password 'new-password'

/usr/local/mysql//bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

See the manual for more instructions.

You can start the MySQL daemon with:

cd . ; /usr/local/mysql//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!

這樣就成功初始化數(shù)據(jù)了。
