Bài 1 : Hướng dẫn căn bản đào coin bằng vps ubuntu

ok bạn cám ơn nhé $$ vậy chua quá :v thôi nhường mấy ae ăn vps sll :v

 

Đi reg VPS free thôi )
Được bao nhiêu hay bấy nhiêu :3

 

tuyệt dzời, để em thực hành luôn.

 

VPS free không ăn thua đâu bác ơi

 

Script startup của mình khi tạo vps, khởi động lại vẫn chạy được , lưu ý các bạn clone tài khoản github của mình ,rồi edit sscript theo tài khoản của bạn ,edit file rc.local theo tên của các bạn luôn nhé

Code:

#!/bin/bash

if [ -f ${PWD}/cpuminer-xzc/miner.h ]; then
    if pgrep -x "cpuminer" > /dev/null
then
    echo "minerd is running"
else

echo "minerd has been installed, starting now"

cd cpuminer-xzc
     
screen -dmSL cpuminer ./cpuminer -a lyra2z -o stratum+tcp://asia.lyra2z-hub.miningpoolhub.com:20581 -u evilbaby.cpagrow -p 1; sleep 3

   
fi
exit
fi

sudo apt-get update
sudo apt-get install git automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev screen cpulimit -y
sudo sysctl -w vm.nr_hugepages=$((`grep -c ^processor /proc/cpuinfo` * 3))
git clone https://github.com/evilbaby/cpuminer-xzc
cd cpuminer-xzc
./build.sh
sudo cp rc.local /etc/rc.local
echo "minerd is starting"

screen -dmSL cpuminer ./cpuminer -a lyra2z  -o stratum+tcp://us-east.lyra2z-hub.miningpoolhub.com:20581 -u evilbaby.1 -p 1 ; sleep 3 

 

Ban cho minh hoi ti , khi minh lam theo nhu huong dan bai viet cua ban nhap vao
./cpuminer -a cryptonight -o stratum+tcp://us-east.cryptonight-hub.miningpoolhub.com:20580 -u userabc.woker -p x -t 1 --background

no hien ra loi nay
-bash: ./cpuminer: Is a directory

Minh tim mai chua bet cai chinh, ban xem gium minh voi. thanks

 

Có lẽ lúc cài bị lỗi gì rồi đó. Lúc cậu gõ lệnh nầy xong thì nó hiện gì?

Code:

sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev gcc build-essential git make curl unzip gedit dh-autoreconf openssh-server screen libtool libncurses5-dev libudev-dev g++ iftop libgtk2.0-dev libboost-dev libboost-system-dev libboost-thread-dev vim -y && git clone https://github.com/JayDDee/cpuminer-opt && cd cpuminer-opt && chmod +x build.sh && ./build.sh || true && sudo make install

 

Cảm ơn bạn, mình đánh nguyên leengj trên thì không thấy gì, để mình làm từng lênh xem có được không. thanks

 

Nhớ chụp hình lại cái lúc mà ko chạy dc nó báo lỗi gì. Thì mình mới biết bị chỗ nào mà cứu nhé

 

e chạy thử nó báo thế này ở bước cài đầu tiên:

Code:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

E: Unable to correct problems, you have held broken packages.
make: *** No rule to make target `install'.  Stop.

 

Bị thiếu mấy lib kèm theo . Thử chạy lệnh nầy

Code:

sudo apt-get install -y libkrb5-dev libglib2.0-dev libgdk-pixbuf2.0-dev libudev0 libpango1.0-dev libatk1.0-dev libcairo2-dev

Xong rồi chạy code lại từ đầu xem nhé. nếu ko dc thì post kết quả lên mình support tiếp

 

Em chạy cái lệnh vừa gửi nó cũng ko được ạ

Code:

root@scw-cb56f7:~# sudo apt-get install -y libkrb5-dev libglib2.0-dev libgdk-pixbuf2.0-dev libudev0 libpango1.0-dev libatk1.0-dev libcairo2-dev

libudev0 is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libglib2.0-dev : Depends: libglib2.0-0 (= 2.32.1-0ubuntu2) but 2.32.4-0ubuntu1 is to be installed
                  Depends: libglib2.0-bin (= 2.32.1-0ubuntu2) but it is not going to be installed

Vậy thử lệnh nầy nhé

Code:

sudo apt-get aptitude install -y libkrb5-dev libglib2.0-dev libgdk-pixbuf2.0-dev libudev0 libpango1.0-dev libatk1.0-dev libcairo2-dev

 

nó lại báo thế này ạ :3

Code:

root@scw-53bd0c:~# sudo apt-get aptitude install -y libkrb5-dev libglib2.0-dev libgdk-pixbuf2.0-dev libudev0 libpango1.0-dev libatk1.0-dev libcairo2-dev
E: Invalid operation aptitude
root@scw-53bd0c:~#

 

Sorry, e chạy nhầm sang con ubutun 12 :3
Em cài lại trên con ubutun 16 chạy thì bị thế này:

Sorry cậu, Nhầm lệnh

Chạy cái nầy trước để cài aptitude

Code:

sudo apt install aptitude -y

Xong chạy lệnh nầy

Code:

sudo aptitude install -y libkrb5-dev libglib2.0-dev libgdk-pixbuf2.0-dev libudev0 libpango1.0-dev libatk1.0-dev libcairo2-dev

Rồi chạy lại code nhé

 

Bác ơi hóng bài tối ưu đào coin trên vps windows quá đi ạ :3

 

Admin ơi cho em hỏi
TH1 : 1 cpu 64 core
Th2 : 64 Cpu 1 core
Thì TH nào đào đc hiệu xuất cao hơn hả admin

 

Cho em hỏi, em có khoảng hơn chục con AWS edu được tặng thêm 75$, limit 20. Nếu đăng ký loại VPS 1gb - 1core thì được 1 năm, còn nếu quá thì nó tính tiền, hết tiền thì sus. Theo các bác nên tạo 1 core thôi hay chơi max core luôn nhỉ

 

1 core hiệu xuất cao nhất nhé
