开启mysql：
./support-files/mysql.server start
报错:
./support-files/mysql.server: line 276: cd: /usr/local/mysql: No such file or directory
Starting MySQL ERROR! Couldn't find MySQL server (/usr/local/mysql/bin/mysqld_safe)
mysql的tar.gz安装包的默认安装目录为/usr/local/mysql， 这时候我们需要修改/support-files/mysql.server文件的basedir和datadir目录路径为我们环境所在的mysql的basedir和datadir路径
