安装时运行

./scripts/mysql_install_db --defaults-file=/home/gzwangweihao/local/mysql/my.cnf -user=gzwangweihao --basedir=/home/gzwangweihao/local/mysql --datadir=/home/gzwangweihao/local/mysql/data --socket=/home/gzwangweihao/tmp/mysql.sock

./bin/mysqld_safe --defaults-file=/home/gzwangweihao/local/mysql/my.cnf --sock=/home/gzwangweihao/tmp/mysql.sock --user=gzwangweihao &

指定了sock等路径
安装完毕后，运行

查看33306端口mysqld再执行。
然后

./bin/mysqladmin -u gzwangweihao password '123456' -P33306

报错

./bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

配置文件如下：

basedir = /home/gzwangweihao/local/mysql
datadir = /home/gzwangweihao/local/mysql/data
port = 33306
socket = /home/gzwangweihao/tmp/mysql.sock

求助是哪里出了问题啊，感激不尽
