还有我现在新建了一个用户，用mysql -h localhost -u user01 -p 可以进去，但用
mysql -h 192.168.0.1 -u user01 -p 出现error 1045:Access denied for user:'user01@hostname'<Using password:YES>我该如何更改我的设置，谢谢！

输入mysql -h 192.168.0.1 -P 3306 -u root -p 后出现如下信息，
mysql Ver 11.16 Distrib 3.23.49, for Win95/Win98 (i32)
Copyright (C) 2000 MySQL AB & MySQL Finland AB & TCX DataKonsult AB
This software comes with ABSOLUTELY NO WARRANTY. This is free software,
and you are welcome to modify and redistribute it under the GPL license

Usage: mysql [OPTIONS] [database]

-?, --help Display this help and exit.
-A, --no-auto-rehash No automatic rehashing. One has to use 'rehash' to
get table and field completion. This gives a quicker
start of mysql and disables rehashing on reconnect.
-B, --batch Print results with a tab as separator, each row on
a new line. Doesn't use history file.
--character-sets-dir=...
Directory where character sets are located.
-C, --compress Use compression in server/client protocol.
-D, --database=.. Database to use.
--default-character-set=...
Set the default character set.
-e, --execute=... Execute command and quit. (Output like with --batch)
-E, --vertical Print the output of a query (rows) vertically.
-f, --force Continue even if we get an sql error.
-g, --no-named-commands
Named commands are disabled. Use \* form only, or
use named commands only in the beginning of a line
ending with a semicolon (;) Since version 10.9 the
client now starts with this option ENABLED by
default! Disable with '-G'. Long format commands
still work from the first line.
-G, --enable-named-commands
Named commands are enabled. Opposite to -g.
-i, --ignore-space Ignore space after function names.
-h, --host=... Connect to host.
-H, --html Produce HTML output.
-L, --skip-line-numbers
Don't write line number for errors.
--no-tee Disable outfile. See interactive help (\h) also.
-n, --unbuffered Flush buffer after each query.
-N, --skip-column-names
Don't write column names in results.
-O, --set-variable var=option
Give a variable an value. --help lists variables.
-o, --one-database Only update the default database. This is useful
for skipping updates to other database in the update
log.
-p[password], --password[=...]
Password to use when connecting to server
If password is not given it's asked from the tty.
-W, --pipe Use named pipes to connect to server

-P, --port=... Port number to use for connection.
-q, --quick Don't cache result, print it row by row. This may
slow down the server if the output is suspended.
Doesn't use history file.
-r, --raw Write fields without conversion. Used with --batch
-s, --silent Be more silent.
-S --socket=... Socket file to use for connection.
-t, --table Output in table format.
-T, --debug-info Print some debug info at exit.
--tee=... Append everything into outfile. See interactive help
(\h) also. Does not work in batch mode.
-u, --user=# User for login if not current user.
-U, --safe-updates[=#], --i-am-a-dummy[=#]
Only allow UPDATE and DELETE that uses keys.
-v, --verbose Write more. (-v -v -v gives the table output format)
-V, --version Output version information and exit.
-w, --wait Wait and retry if connection is down.

Default options are read from the following files in the given order:
C:\WINNT\my.ini C:\my.cnf
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit
--no-defaults Don't read default options from any options file
--defaults-file=# Only read default options from the given file #
--defaults-extra-file=# Read this file after the global files are read

Possible variables for option --set-variable (-O) are:
connect_timeout current value: 0
max_allowed_packet current value: 16777216
net_buffer_length current value: 16384
select_limit current value: 1000
max_join_size current value: 1000000

假设你的 MySQL 安装在 192.168.0.1 上
TCP/IP 端口为 3306
用户名为 root
密码为 123

mysql -h 192.168.0.1 -P 3306 -u root -p

to swotcoder,但是外面的机器是，不认你的机器名，我也试过用域名/端口号，也是上面同样的错误。

刚装的时候是没有密码，但是我用mysqladmin改密码后就进不去了。另外，机器是刚重装系统，上面只有一个mysql，通过localhost:3306是可以访问的，我想MySQL服务器的TCP/IP的端口是3306，应该是没有问题的，但是为什么我从其它机器上访问就出错呢？还望高手指点一二！谢谢！

你的MySQL访问要使用机器名/端口号码，不是用ip/port访问。

这是因为你寻的用户是这样的

+--------------+--------------+---------------+
| Host | User | Password |
+--------------+--------------+---------------+
| localhost | user01 | ************* |
+--------------+--------------+---------------+

你只有建立一个
Host = 192.168.0.1 的用户，
你才能使用 IP

error 1045:Access denied for user:'root@localhost'<Using password:YES>

权限问题,
如果你的 MySQL 是刚安装的,
那你的 root 是没有密码的,
用下面的语句试试
mysql -h localhost -u root

Cannot connect to MySQL server on 192.168.0.1:3306.Is there a MySQL server running on the machine/port you are trying to connect to?

192.168.0.1 是你的 MySQL 服务器的地址吧,你的 MySQL 服务器的TCP/IP的端口是 3306 吗?
如果都是,你要问我这是为什么,
呵呵,我不知了
