求助！编译安装mysql时，最后一步启动服务出错

[coolman366]

我用的是ubuntu8.04版的, mysql.5.0.22.tar.gz
按照以下要求安装
首先下载编译需要的一些工具,这些工具在默认安装的ubuntu上可能没有,需要手动安装 sudo apt-get install g++ gcc make automake perl 安装好所有需要的工具

下载需要的libncurses5-dev、kdelibs_dev 和 kdelib

sudo apt-get update

apt-get install build-essential

sudo apt-get install libncurses5-dev

sudo apt-get install kdelibs4-dev

sudo apt-get install kdelibs4c2a

安装mysql，使用root权限

shell> groupadd mysql

shell> useradd -g mysql mysql

shell> gunzip < mysql-VERSION.tar.gz | tar -xvf -

shell> cd mysql-VERSION

shell> ./configure --prefix=/usr/local/mysql

shell> make

shell> make install

shell> cp support-files/my-medium.cnf /etc/my.cnf

shell> cd /usr/local/mysql

shell> chown -R mysql .

shell> chgrp -R mysql .

shell> bin/mysql_install_db --user=mysql

shell> chown -R root .

shell> chown -R mysql var
shell> bin/mysqld_safe --user=mysql &




但是最后一步sudo bin/mysqld_safe --user=mysql & 时出错
administrator@administrator-desktop:/usr/local/mysql$ sudo bin/mysqld_safe --user=mysql&
[3] 26929
administrator@administrator-desktop:/usr/local/mysql$ nohup: 忽略输入重定向错误到标准输出端
Starting mysqld daemon with databases from /usr/local/mysql/var
STOPPING server from pid file /usr/local/mysql/var/administrator-desktop.pid
090420 11:49:38 mysqld ended


[3]- Done sudo bin/mysqld_safe --user=mysql

我该怎么纠正？
