    How much free space do you have on your droplet?

    You appear to be out of space. From '/' if you run this command it will tell you your top 10 directories in terms of disk space used.

    du -aBM 2>/dev/null | sort -nr | head -n 10

    You can change the '10' into any value you want ... 20, 30, etc.

    There is another more "pretty" tool I found but you may not have enough space to install the utility.

  • mformainuddin August 23, 2017

    ok i typed:

    du -aBM 2>/dev/null | sort -nr | head -n 10

    and it shows:

    Then what i need to do???

  • iteagle03 August 23, 2017

    And you ran this command from the root of the directory ( '/' )? If you run 'pwd' and get something other than '/' you are not at the root directory. Once you are at root ('cd /') and run that du command, you should get something like this:

    1936M   .
1209M   ./usr
361M    ./usr/src
327M    ./usr/lib
264M    ./usr/share
246M    ./var
222M    ./usr/bin
212M    ./lib
173M    ./var/lib
159M    ./lib/modules

    Most of my disk usage is in the '/usr' directory, which is fine. I'm only using about 2GB out of 30GB for my droplet. :)

  • iteagle03 August 23, 2017

    Ouch. You have so little space you have literally no wiggle room to work with.

    Well, let's wander into the /var/log directory and run the command 'ls -halt' and see if we have any large log files we could possibly clear out.

    What are you using this droplet for that has used up so much disk space?

    I'd delete any log file that is a .gz or .1 file that is larger than 5 MB.

    auth.log.1 & btmp.1 are both pretty big.

    I think you need to determine whether you need to keep around any log files older than two months as well (that is a .gz file).

    Then go into either apache2 or nginx (whichever is your webserver) and lets see how big those log files are and see what we can do about them.

    am i need to delete auth.log.1 & btmp.1 or not???

    It's ultimately up to you what you delete but do you see what I am trying to do? I'm trying to go through your logs and clear up some space. Hopefully after clear out some big log files we'll have enough disk space to run the 'sudo du -aBM 2>/dev/null | sort -nr | head -n 10' command (lets add sudo to include some directories that might only be accessible as a sudo or root user). From there you can really dive into where your disk usage is and attempt to resolve that roadblock.

    Another command you can run after clearing out your log files might be 'sudo apt-get autoremove' which will remove any packages that aren't needed by your system.

    It's that or we add some block storage. You will know your sever better than anyone but something has eaten up all your available disk space.

  • mformainuddin August 23, 2017

    @iteagle03
    ok then we remove that btmp.1 file... i think it's a size(89mb) to run 'sudo du -aBM 2>/dev/null | sort -nr | head -n 10'...
    is it ok??? basically i don't have that much skill on that.......& that's why i asked repeatedly...sorry

    So, in regards to your apache2 error it can't write to the directory '/var/log/apache2/'. I have no idea what the problem is with mysql.

  • mformainuddin August 26, 2017

    @iteagle03
    write to the directory '/var/log/apache2/'..... what i need to do???
    Thanks

  • iteagle03 August 26, 2017

    Is the directory present? If so, is the access.log, error.log, and othervhostsaccess.log log files present in the directory?

  • mformainuddin August 26, 2017

Could you let us know what you've already tried to do to resolve your issue?
Have you googled your error? If so have you tried those solutions?
Have you tried purging mysql-server and start again?

@Aprexer

I tried start and stop mysql.service and install mysql tuner... and try to open my.cnf .... that's it

You should first setup a swapfile. and also add line like this
innodb_buffer_pool_size = 20M to the end of the line of your /etc/mysql/my.cnf

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[mysqld]
innodb_buffer_pool_size = 20M```
