1、单节点部署
文档：https://etcd.io/docs/v3.5/install/
1.1、安装
# centos7环境安装etcd
# 1、下载etcd
wget https://github.com/etcd-io/etcd/releases/download/v3.5.11/etcd-v3.5.11-linux-amd64.tar.gz
# 2、解压
tar -xf etcd-v3.5.11-linux-amd64.tar.gz
# 3、进入 etcd-v3.5.11-linux-amd64目录
cd etcd-v3.5.11-linux-amd64
# 4、将etcd、etcdctl、etcdutl移动到/usr/local/bin目录
mv etcd /usr/local/bin/etcd
mv etcdctl /usr/local/bin/etcdctl
mv etcdutl /usr/local/bin/etcdutl
# 5、查看etcd版本
etcd --version
etcdctl version
etcdutl version1.2、启动
# 运行etcd
# 会在当前目录创建data-dir="default.etcd"，wal-dir="default.etcd/member/wal"
etcd
# 指定参数运行
etcd --listen-client-urls=http://$PRIVATE_IP:2379 \
--advertise-client-urls=http://$PRIVATE_IP:2379
# 查看集群状态
etcdctl --endpoints=$ENDPOINTS endpoint status
etcdctl --endpoints=$ENDPOINTS endpoint health1.3、配置
详见：https://etcd.io/docs/v3.5/op-guide/configuration/
You can configure etcd through the following:
- Command-line flags
- Environment variables: every flag has a corresponding environment variable that has the same name but is prefixed withETCD_ and formatted in all caps and snake case. For example, --some-flag would be ETCD_SOME_FLAG.
- Configuration file
1.3.1、使用命令行参数启动etcd
# 使用命令行参数运行etcd
etcd --name 'command-line-flags' --data-dir '/root/command-line-flags'1.3.2、使用环境变量启动etcd
创建/root/etcd.conf配置文件：
cat > /root/etcd.conf <<"EOF"
#[Member]
ETCD_NAME='environment-variable'
ETCD_DATA_DIR='/root/environment-variable'
EOF创建/etc/systemd/system/etcd.service服务配置文件：
cat > /etc/systemd/system/etcd.service <<"EOF"

操作步骤如下：
1、在172.17.0.2节点安装cfssl，生成证书
2、将证书复制到其他节点（172.17.0.3、172.17.0.4）
3、在每个节点运行etcd
4、在172.17.0.2节点查看集群2.2.1、安装cfssl
2.2.1.1、安装
# 1、下载cfssl、cfssljson、cfssl-certinfo
# cfssl：用于签发证书
# cfssljson：将cfssl签发生成的证书(json格式)变成文件承载式文件
# cfssl-certinfo：验证查看证书信息
wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 -O /usr/local/bin/cfssl
wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 -O /usr/local/bin/cfssljson
wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64 -O /usr/local/bin/cfssl-certinfo
# 2、给cfssl、cfssljson、cfssl-certinfo添加可执行权限
chmod +x /usr/local/bin/cfssl*2.2.1.2、生成证书
- 配置文件：ca-config.json、ca-csr.json、etcd-csr.json
- 文件内容来源：https://github.com/etcd-io/etcd/tree/main/hack/tls-setup
ca-config.json文件：
{
"signing": {
"default": {
"usages": [
"signing",
"key encipherment",
"server auth",
"client auth"
],
"expiry": "876000h"

}
}ca-csr.json文件：
{
"CN": "Autogenerated CA",
"key": {
"algo": "rsa",
"size": 2048

"size": 2048
},
"names": [
{
"O": "autogenerated",
"OU": "etcd cluster",

}
]
}执行命令：
# 1、创建目录
mkdir -p etcd/ssl
# 2、切换目录
cd etcd/ssl
# 3、创建文件，复制上述ca-config.json、ca-csr.json、etcd-csr.json内容到对应文件
touch {ca-config.json,ca-csr.json,etcd-csr.json}
# 4、生成CA根证书及其私钥
cfssl gencert -initca ca-csr.json | cfssljson -bare ca
# 5、根据CA根证书及其私钥签名生成目标证书和私钥
cfssl gencert -ca ca.pem -ca-key ca-key.pem -config ca-config.json etcd-csr.json | cfssljson -bare etcd
# 6、复制etcd目录到其他节点
scp -r /root/etcd 172.17.0.3:/root/etcd
scp -r /root/etcd 172.17.0.4:/root/etcd2.2.2、节点配置

3.1、使用http通信
# 1、当前主机IP：10.0.8.13，创建目录
mkdir /root/etcd-data
# 2、当前主机IP：10.0.8.13，创建容器
docker run \
-p 2379:2379 \
-p 2380:2380 \
