Linux import Ethereum contract

1.

The smart contract has been written for a long time

if they can add changes, the description is centralized

the contract is written into the Ethereum smart contract, which is a contradiction sentence

the financial customer service doesn't understand, which is very unreliable

How to use the Linux system mining, to use the service of the HA Yu miner, only need two steps, you can mine on the Linux system

1. open the website, input the mobile phone number, select how many CPUs you want to use for mining, the default is to use 50% of the CPU for mining, click to generate your exclusive command and



in two steps, you can mine on Linux system, the money you dig only needs to go to the website of hayu miner, enter your mobile phone number to withdraw< br />

5. Because mining is automatic, there is no need for retail investors to do anything, but once you mine, you are already sharing your idle bandwidth<
popular science principle:
retail side: retail investors pay expensive bandwidth fees, but they usually waste the bandwidth at work and home if they can't use it. But mining can upload this part of bandwidth to the people in need, so retail investors can also get a return
enterprise side: the traffic ore software will intelligently package the collected bandwidth and provide it to video enterprises. Because of this, the flow of ore has the ability to return to retail investors
generally speaking, you can't do nothing. This is because the technology is too intelligent to help you do everything.

6. Copy an existing configuration file and change it to eth1, then change it to the IP in it

for example, the existing / etc / sysconfig / network scripts / eth0
can be roughly as follows:

device = eth0
onboot = yes
bootproto = static
iPad Dr = 192.168.1.20
netmask = 255.255.255.0
gateway = 192.168.1.255

an existing configuration file and change it to eth1 iPad If Dr is changed to 192.168.1.21, an eth1 with IP 192.168.1.21 will appear

7. "This is how to learn Linux" is a self-study book focusing on practical Linux system technology. Let's learn it together.

8. CP ifcfg-eth0 ifcfg-eth1
then VI ifcfg-eth1
according to the parameter settings in it, you can

the easiest way is if you have the installation of subset
use subset

9. Temporary solution 1:
use the command ifconfig eth0 192.168.1. X to set the IP of eth0 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 ifcfg-eth0's device, bootproto, onboot, IPADDR, gateway, dns1, domain, netmask, network, name, etc, For example:
device = eth0 physical device name
IPADDR = 192.168.1. X IP address
netmask = 255.255.255.0 subnet mask
Network = 192.168.1.0 specified network, The gateway address
broadcast = 192.168.1.255 is automatically calculated by IP address and subnet mask, According to the IP address and subnet mask, we can automatically calculate whether the device can be activated when
onboot = [yes | no] booting
userctl = [yes | no] whether the non root user can control the device
bootproto = [none | static | BOOTP | DHCP] booting without protocol | static allocation | BOOTP | DHCP protocol
hwaddr = 00:00 13: D3: 27:9f: 80 MAC address
name = eth0 name
3. After the above settings, it can succeed under normal circumstances. If there is still a problem, add ifup eth0 to the file / etc / rc.d/rc.local (/ etc / rc.local script is executed after all other initialization scripts are executed)
4. Restart the computer, OK
other network control commands:
ifdown eth0, ifconfig eth0 down / / shut down the network
ifup eth0 Ifconfig eth0 up / / start the network
- set DNS configuration file location / etc / resolv. Conf
- set service network start / / start the network service
service network stop / / stop the network Service
srvice network restart / / restart the network service
service network status / / view the network service status

10. Add ifconfig eth0 directly: 1 192.168.1.111 netmask 255.255.255.0
