Ethernet mining tutorial

1. Create a new folder on the hard disk, which is better than C: eth. Then all the mining software is stored here

2. Download the following software

1) geth -- select geth win download and unzip

2) ethernet -- download and unzip to the same folder and rename it as "miner"

3) Ethereum wallet -- Download the win Ethereum wallet and unzip it and rename it as "wallet"

install all the software

3 Open the command prompt (click win and R at the same time, or click Start menu and enter CMD). The command prompt is a command line parser that allows you to execute command input software in the operating system

After

, you will have Ethereum wallet. But there is no balance, so next you need to build an ethminer. It's time to minimize your wallet

Mining

2. It contains only numbers 0 ~ 9 and letters a ~ F, a total of 16 symbols

3. Build / env.sh go run build / ci.go install. / CMD / geth
make: * * [geth] error 1
there is no such directory, or the directory has insufficient permissions

4. My computer - & gt; Attribute - & gt; Advanced - & gt; Environment variables - & gt; Add the following environment variables to the system variables:
java_ The home value is: the directory where JDK is installed, and mine is C: &# 92; Program Files\ Java\ jdk1.6.0_ 34
the classpath value is:;% JAVA_ HOME%\ lib\ tools.jar;% JAVA_ HOME%\ lib\ dt.jar;% JAVA_ HOME%\ bin;( Pay attention to the & quot& quot; To add)
Path: append at the beginning.;% JAVA_ HOME%\ bin;% JAVA_ HOME%\ jre\ bin;( Pay attention to the & quot& quot; To add)

after the installation, you can check whether the JDK is installed successfully. Open the CMD window and enter Java – version to view the version information of JDK.

5. You can only dig it. If you can't, you can only buy it by auction house. It's a little less than 10 in 2 hours. Where did you dig it? You can go to Huanxing mountain and xilisus. The output is still good. You can also find the transformation master's Alchemy to transform AOJIN ingot, which can be critical hit.

6. Ifcfg-eth0 is not a directory. If it exists, it should be a file

7. All in the / etc directory. But the location is different. IP and gateway are recorded in the ifcfg-eth0 file under / etc / sysconfig / network scripts
DNS is recorded in resolv.conf under / etc
the domain name is in named.conf under / etc

8. Network script is the real IP. If you want to change IP, change ifcfg ethx under network script

eth0 is the default naming method for versions below 7
in your system, 33 is the correct network card configuration file
hope to help you, please adopt it, thank you

10. The solution of eth0 device cannot be found in CentOS
Problem Description:
ifconfig command cannot find eth0 device, and / etc / sysconfig / network scripts / has only ifcfg Lo file, but no ifcfg-eth0
temporary solution 1:
using the command ifconfig
eth0
192.168.1. X, the IP of eth0 can be set normally. This method is only a temporary method, and it will be invalid after the system is restarted
permanent solution 2:
1. Create ifcfg-eth0 file in / etc / sysconfig / network scripts / directory
2. Set device, bootproto, onboot, IPADDR, gateway, dns1, domain, netmask, network, name, etc. of ifcfg-eth0 correctly, for example:
device = eth0
