mysqld_safe启动报错问题

在我启动第一次启动mysql脚本时候发现

[root@template 3306]# /data/3306/mysql_3306 start
Starting MySQL...
220226 21:20:32 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&
See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information

1、mysqld_safe只认识/usr/local/mysql/bin/mysqld（也许是配置问题）

2、my.cnf只能放置在/etc/下面，不然使用–defaults-file也不能读取my.cnf文件（疑惑？？？）解决方法

配置一个软连接指向 /usr/local/mysql/bin

mkdir /usr/local/mysql/bin
​
[root@template bin]# ln -s /appmysql/mysql-5.6.34-linux-glibc2.5-x86_64/bin/mysqld /usr/local/mysql/bin/mysqld

再次启动查看结果

[root@template 3306]# /data/3306/mysql_3306 start
