cenots7 部署etcd集群

1. 安装etcd

yum install -y etcd

2. 配置文件

# master配置ETCD_NAME=etcdmaster ETCD_DATA_DIR="/var/lib/etcd/etcd-master.etcd"    ETCD_LISTEN_PEER_URLS="http://192.168.1.101:2380"ETCD_LISTEN_CLIENT_URLS="http://192.168.1.101:2379,http://127.0.0.1:2379"ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.1.101:2380"ETCD_INITIAL_CLUSTER="etcdmaster=http://192.168.1.101:2380,etcdnode1=http://192.168.1.102:2380,etcdnode2=http://192.168.1.103:2380"ETCD_INITIAL_CLUSTER_STATE="new"ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-00"ETCD_ADVERTISE_CLIENT_URLS="http://192.168.1.101:2379"

# etcdnode01ETCD_NAME=etcdnode01ETCD_DATA_DIR="/var/lib/etcd/etcd-master.etcd"    ETCD_LISTEN_PEER_URLS="http://192.168.1.102:2380"ETCD_LISTEN_CLIENT_URLS="http://1092.168.1.102:2379,http://127.0.0.1:2379"ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.6.74.6:2380"ETCD_INITIAL_CLUSTER="etcdmaster=http://192.168.1.101:2380,etcdnode1=http://192.168.1.102:2380,etcdnode2=http://192.168.1.103:2380"ETCD_INITIAL_CLUSTER_STATE="new"ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-00"ETCD_ADVERTISE_CLIENT_URLS="http://192.168.1.102:2379"

3. 配置启动命令

cat /usr/lib/systemd/system/etcd.service

[Unit]Description=Etcd ServerAfter=network.targetAfter=network-online.targetWants=network-online.target[Service]Type=notifyWorkingDirectory=/var/lib/etcd/EnvironmentFile=-/etc/etcd/etcd.confUser=etcdExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /usr/bin/etcd --name=\"${ETCD_NAME}\" \--data-dir=\"${ETCD_DATA_DIR}\" \--listen-peer-urls=\"${ETCD_LISTEN_PEER_URLS}\" \--listen-client-urls=\"${ETCD_LISTEN_CLIENT_URLS}\" \--advertise-client-urls=\"${ETCD_ADVERTISE_CLIENT_URLS}\" \--initial-cluster-token=\"${ETCD_INITIAL_CLUSTER_TOKEN}\" \--initial-cluster=\"${ETCD_INITIAL_CLUSTER}\" \--initial-cluster-state=\"${ETCD_INITIAL_CLUSTER_STATE}\""Restart=on-failureLimitNOFILE=65536[Install]WantedBy=multi-user.target

4. 管理

分别启动各种节点 systemctl start etcd

# 查看群集状态命令etcdctl member list
