etcd集群部署

1.环境准备

主机名	IP地址	CPU	内存	硬盘
gztxy-prd-etcd01	192.168.1.1	2	4	100G
gztxy-prd-etcd02	192.168.1.2	2	4	100G
gztxy-prd-etcd03	192.168.1.3	2	4	100G

2.安装并配置

yum安装

yum install etcd -y

配置

#etcd01
cat > /etc/etcd/etcd.conf <<EOF

启动并添加开机启动

systemctl start etcd
systemctl enable etcd

3.测试

添加etcd数据并进行测试

#添加数据，添加一个behavior值的数据
etcdctl -C http://192.168.1.11:2379 set /behavior "["192.168.1.11:80", "192.168.1.12:80"]"
#查询数据
curl http://192.168.1.11:2379/v2/keys/behavior
