MySql won't start after installation on Ubuntu server 14.04.1

Question

I'm new to Ubuntu server and MySql. I'm attempting to create a server in VirtualBox that I can use for web development and testing before deploying to a real server. I have Ubuntu server 14.04.1 installed and running in a virtual machine. PHP is working fine. I can access anything I put in the /var/www/html folder from my web browser on my host machine. I cannot get MySql to start. I tried uninstalling the version that came with Ubuntu and reinstalling from the MySql repository at dev.mysql.com and it still won't start. The previous version was giving me an error with a ".sock" file, the name of which I cannot remember. Now it simply says it cannot start, stating only that the log files are inaccessible. I have been searching google for almost two days and have not found any solutions that work. I am fairly new to Unix terminals, so forgive me if I misunderstand things.

MySql service status:

eric@Server:~$ sudo service mysql status
sudo: /var/lib/sudo owned by uid 1000, should be uid 0
[sudo] password for eric:
* MySQL Community Server 5.6.21 is not running

Here is what I get when I try to start MySql:

eric@Server:~$ sudo service mysql start
sudo: /var/lib/sudo owned by uid 1000, should be uid 0
[sudo] password for eric: 
No directory, logging in with HOME=/

......
* MySQL Community Server 5.6.21 did not start. Please check logs for more details.

And here is mysql --verbose --help (I cut out the help section from the top)

eric@Server:~$ sudo mysql --verbose --help

Let me know if you need any other information. I really want to get this working so I can start my web development.

Thank you in advance for any and all help!

Solution 1

Yes, it seems to be permission problem. From your logs, your MySQL cannot create any log files in /var/log/mysql , so you should change the permission to mysql user : chown -R /var/log/mysql and then restart mysql process again.

Solution 2

I suspect that this might an issue with the permission MySQL user to run the execute. Please try running the below command and check whether your issue is fixed.

chown mysql /var/run/mysqld

Show the output for ls -lF /var/log/mysql

[muru]

Pretty certain you did chown $USER:$USER -R /.
