1,添加etcd用户及用户组
groupadd etcd && useradd -c "Etcd user" -g etcd -s /sbin/nologin -r etcd
etcd用户
tail /etc/passwd
etcd:x:995:1001:Etcd user:/home/etcd:/sbin/nologin
2,下载二进制文件
DOWNLOAD_URL=https://storage.googleapis.com/etcd #etcd存储地址
ETCD_VER=v3.1.5 #设置etcd版本号
wget ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz
tar xvf etcd-${ETCD_VER}-linux-amd64.tar.gz
3,部署文件
将如下内容写入文件 /etc/etcd/etcd.conf 中：
# [member]
ETCD_NAME=default
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
# ETCD_WAL_DIR=""
# ETCD_SNAPSHOT_COUNT="10000"
# ETCD_HEARTBEAT_INTERVAL="100"

# ETCD_CORS=""
#
# [cluster]
# ETCD_INITIAL_ADVERTISE_PEER_URLS="http://localhost:2380"
# if you use different ETCD_NAME (e.g. test), set ETCD_INITIAL_CLUSTER value for this name, i.e. "test=http://..."
# ETCD_INITIAL_CLUSTER="default=http://localhost:2380"
# ETCD_INITIAL_CLUSTER_STATE="new"
# ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"

# ETCD_PEER_TRUSTED_CA_FILE=""
# [logging]
# ETCD_DEBUG="false"
# examples for -log-package-levels etcdserver=WARNING,security=DEBUG
# ETCD_LOG_PACKAGE_LEVELS=""
记得创建 目录
#mkdir -p /var/lib/etcd/default.etcd
并修改权限
#chown -R etcd:etcd /var/lib/etcd/
4,将 etcd, etcdctl放入 /usr/bin/下，并将如下内容写进/usr/lib/systemd/system/etcd.service文件
#cd etcd-${ETCD_VER}-linux-amd64
#cp etcd /usr/bin/
#cp etcdctl /usr/bin/

[Install]
WantedBy=multi-user.target
5,运行
#systemctl start etcd.service && systemctl enable etcd
#systemctl status etcd
