I am new to Ubuntu. I am running Ubuntu 12.10. I am trying to install apache,php,mysql. However I have installed apache and it is running perfectly.
sudo apt-get install apache2
But when I tried to install mysql using following command
sudo apt-get install mysql-server
After download, it asked for password but after entering and confirming password. I get following error message.
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.
after clicking on the ok button on the prompt I am getting following message on terminal
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. dpkg: error processing mysql-server-5.5 (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: mysql-server-5.5 E: Sub-process /usr/bin/dpkg returned an error code (1)
Mysql error log says
