etcd集群部署

1.安装

wget https://github.com/etcd-io/etcd/releases/download/v3.3.12/etcd-v3.3.12-linux-amd64.tar.gz

tar zxvf etcd-v3.3.12-linux-amd64.tar.gz

cd etcd-v3.3.12-linux-amd64

cp etcd etcdctl /usr/bin/

2.配置

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

[Unit]
Description=Etcd Server
After=network.target
After=network-online.target
Wants=network-online.target

[Service]
Type=notify
WorkingDirectory=/var/lib/etcd/
EnvironmentFile=-/etc/etcd/etcd.conf
User=etcd
# set GOMAXPROCS to number of processors
ExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /usr/bin/etcd --name=\"${ETCD_NAME}\" --data-dir=\"${ETCD_DATA_DIR}\" --listen-client-urls=\"${ETCD_LISTEN_CLIENT_URLS}\""
Restart=on-failure
LimitNOFILE=65536

[Install]
WantedBy=multi-user.target

vi  /etc/etcd/etcd.conf

#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://0.0.0.0:2380"
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379,http://0.0.0.0:4001"
ETCD_NAME="node1"
#[Clustering]
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.56.14:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://192.168.56.14:2379,http://192.168.56.14:4001"
ETCD_INITIAL_CLUSTER="master=http://192.168.56.11:2380,node1=http://192.168.56.14:2380"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"
ETCD_INITIAL_CLUSTER_STATE="new"

3.启动服务并测试

systemctl restart etcd

systemctl status etcd

etcdctl member list   #查看状态

etcdctl  set  hello  aaa   #设置测试值

到另外一台节点 etcdctl get hello  能看到值即可
