执行mysqld_safe报错：

[root@edu data]# /usr/local/mysql5.7/bin/mysqld_safe --user=mysql

160427 12:41:28 mysqld_safe Logging to '/renqinglei/mysql/log/mysql_error.log'.

160427 12:41:28 mysqld_safe The file /usr/local/mysql/bin/mysqld

does not exist or is not executable. Please cd to the mysql installation

directory and restart this script from there as follows:

./bin/mysqld_safe&

后台错误日志报：

160427 12:41:28 mysqld_safe The file /usr/local/mysql/bin/mysqld

根据网上所说重新初始化数据库也不好使，

依据  mysqld_safe只认识/usr/local/mysql/bin/mysqld路径的mysqld

于是调整在当前目录创建了一个软链接，问题解决。

[root@edu local]# ln -s mysql5.7/  mysql

记录此错，仅为以后提醒。
