安装数据库时有毛病，不知道是怎么回师！

[root@net mysql]./configure --prefix=/usr/local/mysql
[root@net mysql]make
[root@net mysql]make install
[root@net mysql]scripts/mysql_install_db
[root@net mysql]/usr/sbin/groupadd mysqlgrp
[root@net mysql]/usr/sbin/useradd -g mysqlgrp mysqlusr
[root@net mysql]cd /usr/local/mysql
[root@net mysql]chown -R mysqlusr.mysqlgrp var
[root@net mysql]chmod -R go-rwx var
[root@net mysql]bin/safe_mysqld --user=mysqlusr &
[root@net mysql]bin/mysqladmin -u root status
//然后就出这种错//
mysqladmin:connect to server at'local host'failed
error:'can't connect to local mysql server through socket '/tmp/mysql.sock'(2)'
check that mysqd is running and that the socket:'/tmp/mysql.sock'exists!
[root@net mysql]
-----------------------------------------------------------------------------
//然后输入//
./saft_mysqld -user=mysql&
//出现了//
[3]491
[2] Exit 127 ./saft_mysqld -user=mysql
[root@net bin] ./saft_mysqld :no such file or directory
[3]127 ./saft_mysqld -user=mysql
//这是怎么回事//
