問(wèn)題描述

1、mysql 新安裝的，環(huán)境變量也配置了，正常使用了半個(gè)月了，今天想改一下mysql的密碼，結(jié)果不知道哪些弄錯(cuò)了，就出現(xiàn)問(wèn)題了。重新啟動(dòng)mysql,輸入賬號(hào)密碼后就跳出一大堆內(nèi)容后，但卻進(jìn)不了mysql.2、跳出一大堆的內(nèi)容如下

mysql Ver 14.14 Distrib 5.5.53, for Win32 (AMD64)Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Usage: mysql [OPTIONS] [database] -?, --help Display this help and exit. -I, --help Synonym for -? --auto-rehash Enable automatic rehashing. One doesn’t need to use ’rehash’ to get table and field completion, but startup and reconnecting may take a longer time. Disable with --disable-auto-rehash. (Defaults to on; use --skip-auto-rehash to disable.) -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. --auto-vertical-output Automatically switch to vertical output mode if the result is wider than the terminal width. -B, --batch Don’t use history file. Disable interactive behavior. (Enables --silent.) --character-sets-dir=name Directory for character set files. --column-type-info Display column type information. -c, --comments Preserve comments. Send comments to the server. The default is --skip-comments (discard comments), enable with --comments. -C, --compress Use compression in server/client protocol. -#, --debug[=#] This is a non-debug version. Catch this and exit. --debug-check Check memory and open file usage at exit. -T, --debug-info Print some debug info at exit. -D, --database=name Database to use. --default-character-set=name Set the default character set. --delimiter=name Delimiter to be used. --enable-cleartext-plugin Enable/disable the clear text authentication plugin. -e, --execute=name Execute command and quit. (Disables --force and history file.) -E, --vertical Print the output of a query (rows) vertically. -f, --force Continue even if we get an SQL error. -G, --named-commands

跳出的內(nèi)容很多，上面是剛開始的一部分。有誰(shuí)能幫忙看下是什么問(wèn)題嗎？

問(wèn)題解答

你應(yīng)該命令輸錯(cuò)了，然后跳出了一大推幫助說(shuō)明，試試下面的命令。

mysql -u root -p
