第一步：部署 master 先筹备好两个脚本文件： 1、vim etcd-cert.sh ##界说ca证书： cat > ca-config.json <<EOF { "signing": { "default": { "expiry": "87600h" }, "profiles": { "www": { "expiry": "87600h", "usages": [ "signing", "key encipherment", "server auth", "client auth" ] } } } } EOF ##实现证书签名 cat > ca-csr.json <<EOF { "CN": "etcd CA", "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "Beijing", "ST": "Beijing" } ] } EOF cfssl gencert -initca ca-csr.json | cfssljson -bare ca - #----------------------- ##指定etcd三个节点之间的通信验证 cat > server-csr.json <<EOF { "CN": "etcd", "hosts": [ "192.168.220.131", "192.168.220.140", "192.168.220.136" ], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "L": "BeiJing", "ST": "BeiJing" } ] } EOF ##生成 ETCD证书 server-key.pem 和 server.pem cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=www server-csr.json | cfssljson -bare server 2、 vim etcd.sh #!/bin/bash # example: ./etcd.sh etcd01 192.168.1.10 etcd02=https://192.168.1.11:2380,etcd03=https://192.168.1.12:2380 ETCD_NAME=$1 ETCD_IP=$2 ETCD_CLUSTER=$3 WORK_DIR=http://www.mamicode.com/opt/etcd cat <<EOF >$WORK_DIR/cfg/etcd #[Member] ETCD_NAME="${ETCD_NAME}" ETCD_DATA_DIR="/var/lib/etcd/default.etcd" ETCD_LISTEN_PEER_URLS="https://${ETCD_IP}:2380" ETCD_LISTEN_CLIENT_URLS="https://${ETCD_IP}:2379" #[Clustering] ETCD_INITIAL_ADVERTISE_PEER_URLS="https://${ETCD_IP}:2380" ETCD_ADVERTISE_CLIENT_URLS="https://${ETCD_IP}:2379" ETCD_INITIAL_CLUSTER="etcd01=https://${ETCD_IP}:2380,${ETCD_CLUSTER}" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster" ETCD_INITIAL_CLUSTER_STATE="new" EOF cat <<EOF >/usr/lib/systemd/system/etcd.service [Unit] Description=Etcd Server After=network.target After=network-online.target Wants=network-online.target [Service] Type=notify EnvironmentFile=${WORK_DIR}/cfg/etcd ExecStart=${WORK_DIR}/bin/etcd --name=\${ETCD_NAME} --data-dir=\${ETCD_DATA_DIR} --listen-peer-urls=\${ETCD_LISTEN_PEER_URLS} --listen-client-urls=\${ETCD_LISTEN_CLIENT_URLS},:2379 --advertise-client-urls=\${ETCD_ADVERTISE_CLIENT_URLS} --initial-advertise-peer-urls=\${ETCD_INITIAL_ADVERTISE_PEER_URLS} --initial-cluster=\${ETCD_INITIAL_CLUSTER} --initial-cluster-token=\${ETCD_INITIAL_CLUSTER_TOKEN} --initial-cluster-state=new --cert-file=${WORK_DIR}/ssl/server.pem --key-file=${WORK_DIR}/ssl/server-key.pem --peer-cert-file=${WORK_DIR}/ssl/server.pem --peer-key-file=${WORK_DIR}/ssl/server-key.pem --trusted-ca-file=${WORK_DIR}/ssl/ca.pem --peer-trusted-ca-file=${WORK_DIR}/ssl/ca.pem Restart=on-failure LimitNOFILE=65536 [Install] WantedBy=multi-user.target EOF systemctl daemon-reload systemctl enable etcd systemctl restart etcd [[email protected] ~]# mkdir k8s [[email protected] ~]# cd k8s/ [[email protected] k8s]# ls etcd-cert.sh etcd.sh [[email protected] k8s]# mkdir etcd-cert [[email protected] k8s]# mv etcd-cert.sh etcd-cert [[email protected] k8s]# ls etcd-cert etcd.sh [[email protected] k8s]# vim cfssl.sh curl -L https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 -o /usr/local/bin/cfssl curl -L https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 -o /usr/local/bin/cfssljson curl -L https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64 -o /usr/local/bin/cfssl-certinfo chmod +x /usr/local/bin/cfssl /usr/local/bin/cfssljson /usr/local/bin/cfssl-certinfo //下载cfssl官方包： [[email protected] k8s]# bash cfssl.sh [[email protected] k8s]# ls /usr/local/bin/ cfssl cfssl-certinfo cfssljson //cfssl：生成证书工具； cfssl-certinfo：检察证书信息； cfssljson：通过传入json文件生成证书
