Deploying etcd

Download the source package. In this example, the source package is saved to the /home directory.

cd /home
wget https://codeload.github.com/etcd-io/etcd/tar.gz/refs/tags/v3.1.20
mv v3.1.20 etcd-3.1.20.tar.gz

Decompress the source package. Rename the generated folder to etcd and save it to the /usr/local directory.
```
tar -zxvf etcd-3.1.20.tar.gz
mv etcd-3.1.20 /usr/local/etcd
```
Set environment variables.
1. Open the /etc/profile file.
```
vim /etc/profile
```
2. Press i to enter the insert mode and add the following content to the end of the file. By default, etcd V2 is used. The API of etcd V3 is needed here.
```
export ETCDCTL_API=3
export ETCD_UNSUPPORTED_ARCH=arm64
```
3. Press Esc, type :wq!, and press Enter to save the file and exit.
Make the environment variables take effect.
```
source /etc/profile
```
Perform the compilation.
```
cd /usr/local/etcd
./build
```
If an error is reported during the compilation, see "Not a git repository" Displayed When Compiling etcd, "no required module provides package" Displayed When Compiling etcd, and "Needed a single revision" Displayed When Compiling etcd.
Search for the generated path. After the compilation is successful, two executable files etcd and etcdctl are generated in the /usr/local/etcd/bin directory.
```
ls /usr/local/etcd/bin
```
Create a data storage path.
```
mkdir -p /usr/local/etcd/data
```
