1、安装 解压安装包，拷贝etcd、etcdctl到/usr/bin下 #此时可以直接etcd启动，但是不建议这么做，因为没有利用配置文件制定参数，则default.etcd会出现在当前目录下，不好管理且不利于参数管理及集群管理。 #以下两个配置文件可以在别的虚拟机以yum install etcd安装之后在相同的位置得到。 将配置文件etcd.conf拷贝到/etc/etcd下 将配置文件etcd.service拷贝到/usr/lib/systemd/system下 启动：systemctl start etcd 状态：systemctl status etcd 停止：systemctl stop etcd 2、集群--这里只讨论static方式 static静态集群：在确切知道节点情况的时候可采取这种方式，又分为两种方式： 命令行方式，如下： etcd --name infra0 --initial-advertise-peer-urls http://192.168.75.137:2380 \ --listen-peer-urls http://192.168.75.137:2380 \ --listen-client-urls http://192.168.75.137:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://192.168.75.137:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://192.168.75.137:2380,infra1=http://192.168.75.138:2380,infra2=http://192.168.75.139:2380 \ --initial-cluster-state new ================================ etcd --name infra1 --initial-advertise-peer-urls http://192.168.75.138:2380 \ --listen-peer-urls http://192.168.75.138:2380 \ --listen-client-urls http://192.168.75.138:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://192.168.75.138:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://192.168.75.137:2380,infra1=http://192.168.75.138:2380,infra2=http://192.168.75.139:2380 \ --initial-cluster-state new ================================ etcd --name infra2 --initial-advertise-peer-urls http://192.168.75.139:2380 \ --listen-peer-urls http://192.168.75.139:2380 \ --listen-client-urls http://192.168.75.139:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://192.168.75.139:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://192.168.75.137:2380,infra1=http://192.168.75.138:2380,infra2=http://192.168.75.139:2380 \ --initial-cluster-state new 配置文件方式，如下： vim /opt/etcd/etcd-v3.1.6-linux-amd64/etcd.conf ETCD_NAME=etcd00 ETCD_DATA_DIR="/opt/etcd/etcd-v3.1.6-linux-amd64/etcd00" ETCD_LISTEN_PEER_URLS="http://192.168.75.137:2380" ETCD_LISTEN_CLIENT_URLS="http://192.168.75.137:2379,http://127.0.0.1:2379" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.75.137:2380" ETCD_INITIAL_CLUSTER="etcd00=http://192.168.75.137:2380,etcd01=http://192.168.75.138:2380,etcd02=http://192.168.75.139:2380" ETCD_INITIAL_CLUSTER_STATE="new" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-00" ETCD_ADVERTISE_CLIENT_URLS="http://192.168.75.137:2379" vim /usr/lib/systemd/system/etcd.service [Unit] Description=EtcdServer 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 #

以上是常规安装方式，我采取的是解压之后自己指定路径的方式，而并没有将etcd和etcdctl拷贝到bin目录下面，也没有采取默认的相关路径。这样有利于配置文件和数据文件的维护。
