求助！mysql无法启动

暮雪清浊

以下是日志信息

以下是安装过程：
./configure --prefix=/usr/local/mysql && make && make install
useradd mysql
cp support-files/my-medium.cnf /etc/my.cnf 控制文件
cd /usr/local/mysql 进入安装目录
chown -R mysql.mysql .
./bin/mysql_install_db --user=mysql 关联mysql用户到mysql
chown -R root  .
chown -R mysql var/
./bin/mysqld_safe --user=mysql


呵呵，幸得bergwolf兄指点，解决了
需要从源码的sql文件夹里面把share目录的东东拷贝到/usr/share/mysql
muxueqz, 或者在/etc/mysql/my.cnf的[mysqld]中添加basedir，指向你安装mysql的prefix目录
还有把/etc/mysql/my.cnf中的--skip-bdb注释掉，那是mysql 5.0的配置遗留下来的
