解决办法：

这主要是没有权限读取，给个权限就OK了

1： 初始化数据库做了没有？

/usr/local/mysql/bin/mysqld_install_db --user=mysql

2：权限问题

chown -R root.mysql /usr/local/mysql/

chown -R mysql /usr/local.mysql/var/

调整lib库路径：

echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf

重新加载配置

ldconfig

启动mysql

/usr/local/mysql/bin/mysql_safe --user=mysql &

查看是否启动了

netstat -ntpl | grep 3306
