Etcd集群搭建与性能测试和调优

搭建脚本如下：

#!/bin/bash

docker ps -a | grep etcd | grep -v k8s
docker rm -f etcd

ETCD_VERSION=3.3.10
TOKEN=my-etcd-token
CLUSTER_STATE=new
NAME_1=etcd-node-0
NAME_2=etcd-node-1
NAME_3=etcd-node-2
HOST_1=192.168.74.36
HOST_2=192.168.74.36
HOST_3=192.168.74.36
CLUSTER=${NAME_1}=http://${HOST_1}:23801,${NAME_2}=http://${HOST_2}:23802,${NAME_3}=http://${HOST_3}:23803

# 对于节点1
THIS_NAME=${NAME_1}
THIS_IP=${HOST_1}
sudo docker run -d --net=host --name ${THIS_NAME} k8s.gcr.io/etcd:${ETCD_VERSION} \
    /usr/local/bin/etcd \
    --data-dir=data.etcd --name ${THIS_NAME} \
    --initial-advertise-peer-urls http://${THIS_IP}:23801 --listen-peer-urls http://${THIS_IP}:23801 \
    --advertise-client-urls http://${THIS_IP}:23791 --listen-client-urls http://${THIS_IP}:23791 \
    --initial-cluster ${CLUSTER} \
    --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}

# 对于节点2
THIS_NAME=${NAME_2}
THIS_IP=${HOST_2}
sudo docker run -d --net=host --name ${THIS_NAME} k8s.gcr.io/etcd:${ETCD_VERSION} \
    /usr/local/bin/etcd \
    --data-dir=data.etcd --name ${THIS_NAME} \
    --initial-advertise-peer-urls http://${THIS_IP}:23802 --listen-peer-urls http://${THIS_IP}:23802 \
    --advertise-client-urls http://${THIS_IP}:23792 --listen-client-urls http://${THIS_IP}:23792 \
    --initial-cluster ${CLUSTER} \
    --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}

# 对于节点3
THIS_NAME=${NAME_3}
THIS_IP=${HOST_3}
sudo docker run -d --net=host --name ${THIS_NAME} k8s.gcr.io/etcd:${ETCD_VERSION} \
    /usr/local/bin/etcd \
    --data-dir=data.etcd --name ${THIS_NAME} \
    --initial-advertise-peer-urls http://${THIS_IP}:23803 --listen-peer-urls http://${THIS_IP}:23803 \
    --advertise-client-urls http://${THIS_IP}:23793 --listen-client-urls http://${THIS_IP}:23793 \
    --initial-cluster ${CLUSTER} \
    --initial-cluster-state ${CLUSTER_STATE} --initial-cluster-token ${TOKEN}
