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 />

2. Use the direction key to move the cursor to the position you need to edit, and then input the characters directly, just like editing the txt file on your computer. Remember to call up: WQ!, Save and exit.

3.

Step 1: Download and register the imtoken, method reference: Apple version if you download the imtoken.

Step 2: transfer the ETH to the imtoken

log in to imtoken and click the QR code figure indicated by the arrow below

5. Batch processing set IP address
I wonder if my friends have such experience. When I bring my notebook to work, because the work needs to be equipped with a fixed IP address, and my home automatically obtains the IP address, I have to set this IP address every day. Is there a simple and convenient way? In fact, we can do a batch process. Each time we want to set the IP address, we just need to run the batch process
first, set the IP address batch processing, save the following code in Notepad as a. Bat file, such as: static. Bat, double-click to run<
@ echo off
echo modify local IP address tool
echo is setting your IP address as a static address, please wait...
Netsh interface IP set address name = & quot; Local connection & quot; source=static addr=192.168.1.102 mask=255.255.255.0
netsh interface ip set address name=" Local connection & quot; source=static gateway=192.168.1.1 gwmetric=0
netsh interface ip set dns name=" Local connection & quot; source=static addr=41.211.224.7 register=primary
netsh interface ip add dns name=" Local connection & quot; addr=41.211.224.3
netsh interface ip set wins name=" Local connection & quot; Source = static addr = none
the related parameters in the above code are described as follows, It can be modified according to your actual situation:
addr = 192.168.1.102 -- IP address
mask = 255.255.255.0 -- subnet mask
gateway = 192.168.1.1 -- gateway
addr = 41.211.224.7 -- preferred DNS
addr = 41.211.224.3 -- standby DNS (if there is no standby DNS, please delete the whole line of code)
2 Set to automatically obtain the IP address, save the following code in Notepad as. Bat file, such as: DHCP. Bat, double-click to run
@ echo off
echo modify local IP address tool
echo is setting to automatically obtain IP address, please wait...
Netsh interface IP set address name = & quot; Local connection & quot; source=dhcp
netsh interface ip set dns name=" Local connection & quot; Source = DHCP
note: the "local link" in the above code is the system default name of the network link in your computer. If you have installed multiple network cards or changed the name of the local link, please change the corresponding local link name in the code to your current name.

6. Under Linux system, you can use CD command to enter / etc / sysconfig / network scripts subdirectory, and then use vi command to edit ifcfg-eth0 network card configuration file.

7.

After entering VI, press I to change to edit mode, and there is a word insert at the bottom of the screen, which is the same as the notepad of windows. Change it. Please refer to the following

after modification, press ESC key, and then enter colon X -: X to save and exit

service network restart

your IP will come out

DEVICE=eth0

BOOTPROTO=none

IPADDR=192.168.0.1

GATEWAY=192.168.0.254

ONBOOT=yes

TYPE=Ethernet

8. 运行下面其中一个配置试下：
system-config-network
system-config-network-tui
system-config-network-gui
配置好够重起下接口：
ifconfig eth0 up
ifconfig eth0 down

DEVICE=eth0
BOOTPROTO=none
HWADDR=00:0C:29:FD:66:D9
ONBOOT=yes
NETMASK=255.255.255.0
IPADDR=192.168.0.14
GATEWAY=192.168.0.1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes

这个是我虚拟机里的，跟你的对丢看

9. For the problem of environment variables, you can echo $path under root and echo $path under ordinary users. The solution to the problem is to declare the environment variables and add the path

10. After modifying the IP address, restart the network card service network restart, or ifup eth0. For more information and articles about Linux, please pay attention to "this is how to learn Linux.".
