Steem Mining - Ubuntu 14.04

in #steemithelp5 years ago (edited)

Hi all,

I am a bit a of a noob when it comes to Linux and mining in general but I saw a few posts on here talking about how to get setup - it seemed simple enough so I decided to give it a go. I have managed to get the miner installed on a server and I am accessing it via ssh

The miner has been running on and off for a couple of days now and it has managed to update the full blockchain.

Lastnight i was able to actually do a little bit of mining, I didn't actually take any screenshots but it looked like it was working (the lines in the console were showing a hash rate along with some other information)

over the couple of days it took to update the blockchain the steemd was crashing from time to time. I just kept an eye on it, connecting every so often to see how it was getting on.

After mining overnight I came to check it this morning and steemd has again crashed (its not running) so I have tried to start it again but now i cannot get past 95% of replaying the blockchain. I have tried multiple times but steemd just keeps crashing and i can never verify the blockchain to continue mining.

I am not getting a specific error message at all, I am actually running steemd and piping to a log file. I check the log file after i see the daemon has failed and the last few lines are:

If there is any other information I can give anyone to help please just ask - I could really do with some suggestions as I don't really know where to go from here.

thanks for taking the time

As far as I can see you are running on very low memory environment. 1gb ram, 4gb swap is kinda pain. I tried to reproduce this using my docker images based on Ubuntu 16.04. And it passed.
However, resync process took about 3 hours and 20 mins :(

Which version of gcc did you use to compile your wallet? Mine is 5.4.0

Hi teego,

thanks for the reply, you're right. I am trying to get this running on AWS free tier. These box's have 1 GB ram and i have setup a 4GB swap file. Another user had suggested turning this off altogether however i haven't tried this as yet.

Sorry I don't know what gcc is? how can i find out what version i have?

thanks once again for the help

GCC, the GNU Compiler Collection. Just run gcc --version or g++ --version to check version

gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

nice dude, ill have a read, was wondering what a Docker is!

thanks v much
