Mysql (+ more) errors in new droplet

Posted October 21, 2014 6.6k views

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

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

Also, some extra info that might help:

    This error seems to be your main problem. It’s why it will not MySql will not start up correctly:

    141021 8:24:22 [ERROR] /usr/sbin/mysqld: Incorrect information in file: './mysql/db.frm'
141021 8:24:22 [ERROR] Fatal error: Can't open and lock privilege tables: Incorrect 
information in file: './mysql/db.frm'

    Were you ever able to start MySql on this droplet? Did you try to import a database from somewhere else? My initial guess is that the database was not imported correctly or was corrupt.

    Agree with @asb
    It appears that this was imported via the data files from an older version of MySQL.

    You need to do a database dump on the old system via 

    mysqldump --all-databases > dump.sql

    then copy the file over, and run

    mysql -u root -p < dump.sql

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?

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

    Have you modified MySQL in any way after installing it? If not, try completely uninstalling it and re-installing it again (ALL DATA will be erased):

    sudo apt-get purge 'mysql*'
sudo rm -r /var/lib/mysql
sudo apt-get install mysql-server mysql-client

  • qooshie October 23, 2014

    ok. I will do that, but is there a way I can migrate my sql databases from one droplet to another through Ftp even if its a different MYSQL version between the two droplets?

    If MySQL is running on the origin server, run this:

    mysqldump -u root -p --all-databases > full_dump.sql

    ^^^ Run this on the origin server, not the destination.

    copy full_dump.sql over to the new server, then run this on the destination:

    (Thanks @kamaln7 for the syntax so I didn’t have to grab it)

    apt-get purge 'mysql*'
rm -rf /var/lib/mysql
rm -rf /etc/mysql/
apt-get install mysql-server mysql-client
service mysql start
mysql -u root -p < full_dump.sql

    This will reset MySQL on the destination server, then re-import the data.

    As the error says:

    E: Unable to fetch some archives, maybe run apt-get update or try with –fix-missing?

    Try running apt-get update and then running apt-get install mysql-server mysql-client again.

    apache2: Syntax error on line 239 of /etc/apache2/apache2.conf: Could not open configuration file /etc/phpmyadmin/apache.conf: No such file or directory

    Apache is trying to load /etc/phpmyadmin/apache.conf but it doesn’t exist. Open /etc/apache2/apache2.conf and delete the line that says Include /etc/phpmyadmin/apache.conf:

    nano +239 /etc/apache2/apache2.conf

    Thank you so much kamain7, that seems to have worked just fine.
    The only thing left now its that I seem to have a problem login in, I know that my default mysql password now is “password” , but still cant run mysql -u root - p without getting an error
    mysqladmin: connect to server at ‘localhost’ failed
    error: 'Access denied for user 'root’@'localhost’ (using password: YES)’

    It may have something to do with the result of running service apache2 restart
    and getting a

    • Restarting web server apache2
      apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName … waiting apache2: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName

    Thank you.

    error: ’Access denied for user ‘root’@'localhost’ (using password: YES)’

    The error is basically saying that you are supplying the wrong password for MySQL’s root user. Make sure you are not passing your system’s root user’s password which is unrelated to MySQL’s root user.

    If you’ve forgotten the password, you can reset it: Recover MySQL root Password - nixCraft.
