Chrome and mysql do not open after changing permission in the /opt folder

Question

I ask for help to solve the following problem.

was using the XAMPP to run PHP applications, and I had to edit the file php.ini which gets into /opt/lampp/etc/

OBS: dentro da pasta opt/ tem outras 2 pastas google/ e lampp/

when saving the file php.ini error appeared permission, so I opened Terminal logging me as ROOT

# sudo su

I went to the root folder and entered the following command:

# chown -R meu_usuario /opt

( then I knew it would have been better chown -R meu_usuario /opt/lampp/etc/php.ini, but the poop was already made )

after that I managed to save the php.ini, however... after restarting the machine. the browser Google Chrome and the database MYSQL of XAMPP no longer work :'(

I’m back to the opt/ folder permission for root

# chown -R root /opt

but still, neither Chrome nor MYSQL database works.

My system

Distributor ID: Ubuntu
Description:    Ubuntu 14.04.1 LTS
Release:        14.04
Codename:       trusty

I thank you in advance for the strength

Answer 1

The default permission is this:

drwxr-xr-x 11 root root 4096 Mar 18 19:17 opt

See if your folder is like this too, if you don’t run the command sudo chmod -R 755 /opt

Then try to reinstall the packages using apt-get install --reinstall <pacote> or removing and installing again;
