Mysql (+ more) errors in new droplet

Hi,

Hey everyone, for the past 15 days i’ve been strugling with problems on my droplet since I’ve lost permission rights on my old one and hence decided to create a new droplet. But it seems im still on a dead end with this one.

So the story goes something like this: I tried several times to upload files through FTP and didn’t work, tried to see if there was a problem with the permissions and couldn’t figure that out and then I’ve noticed that the small files (e.g 54bytes ) were sent just fine, so I then tried to increase the limit from 1024 to something 102400 . During that procedure I found out that under /etc/my.cnf did not exist. So I created a modified copy from /usr/share/doc/mysql-server-5.5/examples/my-small.cnf Then I increased the limits from etc/security/limits.conf And also installed nhm in order for the “show” command to be displayed. (Running: show global variables like ‘open%’; ) to verify that the limit was increased.

After this I tried " service mysqld restart " and got an error: unrecognized service.

Then a apache restart: service apache2 restart

Postfix was not set up. Start with cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf . If you need to make changes, edit /etc/postfix/main.cf (and others) as needed. To view Postfix configuration values, see postconf(1).

After modifying main.cf, be sure to run ‘/etc/init.d/postfix reload’.

So I logged into mysql (mysql -u root -p ) and got a: mysql -u root -p Enter password: ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)

And here is my systems info:

Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-36-generic x86_64)

System information as of Tue Oct 21 07:10:59 EDT 2014

System load: 0.02 Processes: 86 Usage of /: 9.0% of 29.40GB Users logged in: 0 Memory usage: 21% IP address for eth0: 188.226.242.58 Swap usage: 0%

Any help or thoughts whatsoever please, I’m really confused right now.


Also, some extra info that might help:

Ahh.

OK. This may be easier than thought.

First, have you copied your my.cnf file over as well? It would be best to get the file as close as possible (generally speaking), then run this:

chown mysql:mysql /var/lib/mysql -R

then

service mysql start

Thank you for your replies !

@asb I was able to start MySql on this droplet, and yes i tried to move a database from my previous droplet to this one, but since I couldn’t login to mysql on that droplet, and couldn’t use rsync I copied the database through FTP.

@jon231325 trying to run: mysqldump --all-databases > dump.sql I get: mysqldump: Got error: 2002: Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (111) when trying to connect

Thats why I tried copy them through Filezilla and then upload them again to the new one. So at this point im currently unable to login to mysql through both of my droplets…

Any suggestions?
