Geth installation

Combined with various online articles , After more than ten hours of failure , During this period, the virtual machine can't be turned on , But finally successfully installed geth. Next I will show the problems and solutions I have encountered

Catalog

1. System environment

2. Installation of basic tools

3. install cmake

4. install Golang

5. Firewall and network time synchronization

6. Get into geth

7. All environment configurations

---

1. System environment

Windows10,Linux,Centos7.6

2. Installation of basic tools

Download and install git、vim、gcc-c++、ntp Components 、nodejs As well as add epel Third party installation source . These tools are described below ：

The following are the things that need to be prepared for various methods on the network

yum install yum*： Install the tool kit

Cloning tool ：yum install git

• git： Install the relevant components , Download and install all kinds of open source code and tools ;
• vim： Text editing tools , replace vi;
• gcc-c++：c/c++ Compiler tools , be used for golang Lower part c Library compilation and truffle Component compilation
• ntp： Network clock synchronization component ;Ethereum Of rpc The network needs time synchronization ;
• nodejs：ethereum The front-end development JavaScript Package management software
• epel： Third party Internet linux Install package source

Execute the following installation command to download and install the above 6 Something ：

yum update -y && yum install git bzip2 gcc-c++ ntp epel-release nodejs -y

summary ： It may take a little longer to download , But it's OK after downloading , There is no need to operate other things

3. install cmake

Smart contract compilation requires cmake

• wget https://cmake.org/files/v3.15/cmake-3.15.2.tar.gz
• tar -zxvf cmake-3.15.2.tar.gz
• mv cmake-3.15.2 /usr/local/
• cd /usr/local/cmake-3.15.2
• ./bootstrap
• gmake
• gmake install

Configure environment variables

• echo "export PATH=/usr/local/cmake-3.15.2/bin:$PATH" >> /etc/profile
• source /etc/profile
• cmake -version

summary ： I install cmake It was still very smooth  

4. install Golang

• wget https://storage.googleapis.com/golang/go1.10.2.linux-amd64.tar.gz
• tar -C /usr/local -zxzf go1.10.2.linux-amd64.tar.gz
  • I can't install through the first two points go, And the lower version go It may not be compatible
  • So I found the latest version on the Internet go：go1.18.3.linux-amd64.tar.gz
  • Then install it in /usr/local
• echo "export GOROOT=/usr/local/go" >> /etc/profile
• echo "export PATH=/usr/local/go/bin:$PATH" >> /etc/profile
• source /etc/profile

Clone and compile go-ethereum

• cd /usr/local
• git clone https://github.com/ethereum/go-ethereum.git  
  • I have tried this many times , No way git clone cloned （ Only once , Network problems ？）
  • 
  • therefore , I am here github Download directly from the warehouse , adopt Xftp7 to centos7.6
  • GitHub - ethereum/go-ethereum: Official Go implementation of the Ethereum protocol
  • 
  • Put this ZIP Download and unzip the file , Put it in /usr/local/, It's documents go-ethereum-master
  • go-ethereum The file is so many attempts git clone Success comes at once ,go-ethereum-master and go-ethereum The documents inside are exactly the same
  • 
• cd go-ethereum/
  • 
• make all
  • I can't succeed at this step , Many times , It takes the longest time , Encountered various problems , One is as follows ：
  • 
  • The reason for the failure ：GitHub Warehouse ,go-ethereum-build in , No, env.sh The file ！ If any , Change to , hold dos The order was changed to unix after , And it's going to work . because .sh It's a script , It will help us install , And this script is missing . Then the default is dos The order can't be in Linux perform , So it's going to be unix Talent
  • therefore , I can download it directly on the Internet geth The latest version . Address ：Downloads | Go Ethereum
  • And then again /usr/local/Geth place , Unzip and run ok
  • 
• echo "export PATH=$PATH:/usr/local/go-ethereum/build/bin" >> /etc/profile
• source /etc/profile
• geth version verification
  • 

5. Firewall and network time synchronization

Turn on network time synchronization

• systemctl enable ntpd 
• systemctl start ntpd

Turn on the firewall ： Turn on the firewall , open Geth The use of 8087 and 30303 port

• systemctl start firewalld
• firewall-cmd --zone=public --add-port=8087/tcp --permanent
• firewall-cmd --zone=public --add-port=30303/tcp --permanent

6. Get into geth

  Get into geth The file of is shown in the figure , At first, executing permissions is not 777, Need modification :chmod 777 geth. perform ： Direct input geth. It's fine too ：geth --datadir ./data. Will create a data Folder , Used to store our data . The execution is as follows ：
