Centos7下单节点部署etcd服务

一台Centos7的服务器，我的IP：172.16.4.67

登陆到服务器，切换到root用户

#cd /tmp

下载安装包，下载地址：https://github.com/etcd-io/etcd/releases

# wget https://github.com/etcd-io/etcd/releases/download/v3.3.13/etcd-v3.3.13-linux-amd64.tar.gz

解压文件

# tar -zxvf etcd-v3.3.13-linux-amd64.tar.gz

# cd etcd-v3.3.13-linux-amd64

目录下有两个可执行文件etcd 和 etcdctl

# cp etcd /usr/bin/

# cp etcdctl /usr/bin/

配置服务：

# vim /usr/lib/systemd/system/etcd.service    (添加以下内容)

[Unit]
Description=Etcd Server
After=network.target

[Service]
Type=simple
WorkingDirectory=/var/lib/etcd/
EnvironmentFile=-/etc/etcd/etcd.conf
ExecStart=/usr/bin/etcd

[Install]
WantedBy=multi-user.target

# mkdir -p /var/lib/etcd

# mkdir -p /etc/etcd

# vim /etc/etcd/etcd.conf     (添加以下内容)

#[member]
ETCD_NAME=default
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_CLIENT_URLS="http://172.16.4.67:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://172.16.4.67:2379"

# systemctl daemon-reload

# systemctl enable etcd.service

# systemctl start etcd.service

测试服务状态：

# etcdctl cluster-health
