ubuntu - LAMPP's mysql and apache2's mysql are overlapped


I have LAMPP and apache2 both are installed on my ubuntu.
I installed mysql using
Code:
sudo apt-get install mysql-server mysql-common mysql-client
for apache2.
But I don't know how my lampp's mysql and apache2's mysql have been overlapped.

If I want to run my apache2's project which are in /var/www directory.
I have to run following process
1) stop lampp first (for starting apache2 otherwise it gives another weserver is runing error), then
2) start apache2, then
3) start lampp again (for running LAMPP's mysql).

service start mysql does not work for me, I have to run LAMPP's mysql to run my apache2's project.
status of mysql should be stopped otherwise LAMPP's mysql is not started and if LAMPP's mysql is not started, it does connect my database.

Even I am not able to connect on command line from service start mysql, I have to run LAMPP for mysql prompt.

LAMPP is working fine, it does not depend on apache2 and default mysql package.
Any help would be appreciated.

Hi,

You have following packages in your ubuntu

1. apache2 provided by ubtuntu: this installed mysql along with php mysql extension I guess.

2. LAMP: This includes sepaarate apache and a separae mysql

It seems that you are using mysql provided by LAMP for both web servers.

Now, your issue is that you want to run apache2 along with mysql provided by LAMP.

>> But I don't know how my lampp's mysql and apache2's mysql have been overlapped.

This is how it is. Each service is running in a port. Apache is running on 80 port and mysql on 3306 port. So, you can't run 2 web servers or database servers at a time.

However, you can change port of the apache & mysql to make all of them run at a time. However, this involves configuration changes.

If you are ready to do this, LQ forum users can help you.

YES I am using lampp`s mysql for both servers but I dont want to run apache2 with lampp's mysql. It is already running with lampp's mysql. I want to run apache2 with it's mysql.

NO I don't want to run both servers together. I stop lampp when I run apache2 &vice versa. I just want both apache should use their own mysqls. Why apache2's projects show database connectivity with lampp's mysql. Apache2 is independent,why it depends on lampp's mysql. Why dont it use it's own mysql.

what does it show when you stop lampp completely and run apache2 & it's mysql.
First, forget that you have lampp, stop it completely and rename it.

Now run apache2 and try to log into your project. You can't because mysql is not running, it will give database error.
Now start mysql using
$ service start mysql
and try to login again.
If it gives error, what is that?
Try to open phpmyadmin, if it gives error, what is that?

Actually your apache2's mysql is damage, definitely it is giving some error and instead of fixing it, you are using lampp's mysql.
Simply they share same port, you have to close one before starting other.

If you fix your apache2's mysql, you do not need to use lampp's mysql.

I have removed LAMPP completely. Now I start apache2 and try to log-into my project but I am not able to log-in. Invalid username & password
Now I start mysql using service start mysql and try to log into my php project but still I am not able to login. Invalid username & password
If I try to open phpmyadmin, it gives #2003:can't connect to host on 127.0.0.1
Now there is no LAMPP, even I have forget about LAMMP. Now how to start php project using apache2?

Ok, So you have forgotten LAMPP... Good... :-)

when you start apache2 and try to log in to your project, it shows Invalid username & password because mysql is not started.
when you start mysql and try to log in to your project and it shows Invalid username & password. here can be two reasons.
1) You have not created database here in this mysql (Remember this is different than lampp because lampp's database directory is /opt/lampp/var/mysql and apache2's mysql directory is /var/lib/mysql so don't compare and confuse with these two, both are different)
2) and most probably your database configuration is damage because you have said in above comment

If I try to open phpmyadmin, it gives #2003:can't connect to host on 127.0.0.1
so try to open mysql on command prompt using
Code:
$ mysql -h your-host-name -u your username -p
it will give some error, fix the error first and then connect your project with the database.
