我是Ubuntu的新手.我正在运行Ubuntu 12.10.我正在尝试安装apache,php,mysql.但是我已经安装了apache并且运行正常.

sudo apt-get install apache2

但是当我尝试使用以下命令安装mysql时

sudo apt-get install mysql-server

下载后,它要求输入密码,但输入并确认密码后.我收到以下错误消息.

Unable to set password for the Mysql "root" user

An error occurred while setting password for the mysql

administrative user.This may have happened because the account already has a password, or because of a communication problem with the Mysql server.

You should check the account's password after the package installation.

Please read the /usr/share/doc/mysql-server-5.5/README.Debian file for more information.

点击提示上的确定按钮后,我在终端上收到以下消息

Setting up mysql-server-5.5 (5.5.29-0ubuntu0.12.10.1) ...

start: Job failed to start

invoke-rc.d: initscript mysql, action "start" failed.
