etcd3.4.10安装部署
1.安装etcd3.4.10
[root@tike ~]# wget https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz [root@tike ~]# mv etcd-v3.4.10-linux-amd64 /usr/local/etcd [root@tike ~]# cp /usr/local/etcd/etcd /usr/bin/ [root@tike ~]# cp /usr/local/etcd/etcdctl /usr/bin/ [root@tike ~]# mkdir -p /data/etcd/data [root@tike ~]# mkdir -p /etc/etcd/写入配置文件

2.分别启动
加入systemctl
cat>/etc/systemd/system/etcd.service<<EOF [Unit] Description=Etcd Server After=network.target After=network-online.target Wants=network-online.target [Service] Type=notify WorkingDirectory=/data/etcd/data/ 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 EOF启动
[root@tike ~]# systemctl daemon-reload [root@tike ~]# systemctl enable etcd [root@tike ~]# systemctl stop etcd [root@tike ~]# systemctl start etcd [root@tike ~]# systemctl status etcd
3.单机部署etcd
安装：
[root@tike ~]# wget https://github.com/etcd-io/etcd/releases/download/v3.4.10/etcd-v3.4.10-linux-amd64.tar.gz [root@tike ~]# mv etcd-v3.4.10-linux-amd64 /usr/local/etcd [root@tike ~]# cp /usr/local/etcd/etcd /usr/bin/ [root@tike ~]# cp /usr/local/etcd/etcdctl /usr/bin/ [root@tike ~]# mkdir -p /data/etcd/data [root@tike ~]# mkdir -p /etc/etcd/ [root@tike ~]# chmod 700 /data/etcd/data配置服务：
[root@tike ~]# cat > /etc/etcd/etcd.conf <<EOF #[member] ETCD_NAME=etcd145 ETCD_DATA_DIR="/data/etcd/data" ETCD_LISTEN_CLIENT_URLS="http://172.16.18.145:2379" ETCD_ADVERTISE_CLIENT_URLS="http://172.16.18.145:2379" EOF加入systemctl管理
[root@tike ~]# cat > /usr/lib/systemd/system/etcd.service <<EOF [Unit] Description=Etcd Server After=network.target [Service] User=root Type=simple WorkingDirectory=/data/etcd/data/ EnvironmentFile=-/etc/etcd/etcd.conf ExecStart=/usr/bin/etcd [Install] WantedBy=multi-user.target EOF启动
[root@tike ~]# systemctl daemon-reload [root@tike ~]# systemctl enable etcd.service [root@tike ~]# systemctl start etcd.service [root@tike ~]# systemctl status etcd.service验证
