CentOS Linux release 7.4.1708 (Core)
这里部署的etcd集群使用TLS证书对证书通信进行加密,并开启基于CA根证书签名的双向数字证书认证。
cd /usr/local/src
wget http://redirector.gvt1.com/edgedl/go/go1.9.2.linux-amd64.tar.gz
tar -xvf go1.9.2.linux-amd64.tar.gz -C /usr/local
cat >> /etc/profile << EOF
#go的安装路径
export GOROOT=/usr/local/go
#go安装的工具路径
export GOPATH=/apps/local/go
export PATH=$GOROOT/bin:$PATH
EOF
source /etc/profile
GOPATH和GOROOT不能相同
配置生效
[root@kubermaster2 bin]# go version
go version go1.9.2 linux/amd64
将会用使用cfssl生成所需要的私钥和证书
go get -u github.com/cloudflare/cfssl/cmd/...
会在$GOPATH/bin下安装cfssl, cfssjosn, mkbundle等工具。

ca-config.json中可以定义多个profile,分别设置不同的expiry和usages等参数。如上面的ca-config.json中定义了名称为aspire的profile,这个profile的expiry 87600h为10年,useages中:
{
"CN": "aspire",
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "BeiJing",
"L": "BeiJing",
"O": "aspire",
"OU": "cloudnative"
}
]
}
生成CA证书和私钥
cfssl gencert -initca ca-csr.json | cfssljson -bare ca
ls
ca-config.json ca.csr ca-csr.json ca-key.pem ca.pem
创建etcd证书签名请求配置etcd-csr.json
{
"CN": "aspire.etcd",
"hosts": [
"127.0.0.1",
"192.168.4.11",
"192.168.4.12",
"192.168.4.13",
"kubermaster1",
"kubermaster2",
"kubermaster3"
],
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "BeiJing",
"L": "BeiJing",
"O": "aspire.etcd",
"OU": "Operation and maintenance center"
}
]
}
该"hosts"是可以使用该证书域名列表。‘CN’,kube-apiserver从证书中提取该字段作为请求的用户名 (User Name);浏览器使用该字段验证网站是否合法;
该"names"值实际上是名称对象的列表。每个名称对象应至少包含一个“C”,“L”,“O”,“OU”或“ST”值(或这些的任意组合)。这些值是:
下面生成etcd的证书和私钥:
cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=aspire etcd-csr.json | cfssljson -bare etcd
对生成的证书可以使用cfssl或openssl查看
$ cfssl-certinfo -cert etcd.pem
{

...
"cloudnative",
"aspire"
]
},

将生成的CA证书ca.pem, etcd秘钥etcd-key.pem, etcd证书etcd.pem拷贝到各节点的/etc/etcd/ssl目录中
访问github https://github.com/coreos/etcd/releases 找到最新安装包并下载
cd /usr/local/src
wget https://github.com/coreos/etcd/releases/download/v3.2.11/etcd-v3.2.11-linux-amd64.tar.gz
解压缩etcd-v3.2.11-linux-amd64.tar.gz,将其中的etcd和etcdctl两个可执行文件复制到各节点的/usr/bin目录。
在各节点创建etcd的数据目录:
mkdir -p /var/lib/etcd
在每个节点上创建etcd的systemd unit文件/usr/lib/systemd/system/etcd.service,注意替换ETCD_NAME和INTERNAL_IP变量的值:
export ETCD_NAME=kubermaster3
export INTERNAL_IP=192.168.4.13
cat > /usr/lib/systemd/system/etcd.service <<EOF
