etcd 常用配置參數(shù)
--name #指定節(jié)點(diǎn)名稱(chēng)
--data-dir #指定節(jié)點(diǎn)的數(shù)據(jù)存儲(chǔ)目錄，用于保存日志和快照
--addr #公布的 IP 地址和端口；默認(rèn)為 127.0.0.1:2379
--bind-addr #用于客戶(hù)端連接的監(jiān)聽(tīng)地址；默認(rèn)為–addr 配置
--peers #集群成員逗號(hào)分隔的列表；例如 127.0.0.1:2380,127.0.0.1:2381
--peer-addr #集群服務(wù)通訊的公布的 IP 地址；默認(rèn)為 127.0.0.1:2380
--peer-bind-addr #集群服務(wù)通訊的監(jiān)聽(tīng)地址；默認(rèn)為-peer-addr 配置
--wal-dir #指定節(jié)點(diǎn)的 wal 文件的存儲(chǔ)目錄，若指定了該參數(shù) wal 文件會(huì)和其他數(shù)據(jù)文件分開(kāi)存儲(chǔ)
--listen-client-urls #監(jiān)聽(tīng) URL；用于與客戶(hù)端通訊
--listen-peer-urls #監(jiān)聽(tīng) URL；用于與其他節(jié)點(diǎn)通訊
--initial-advertise-peer-urls #告知集群其他節(jié)點(diǎn) URL
--advertise-client-urls #告知客戶(hù)端 URL
--initial-cluster-token #集群的 ID
--initial-cluster #集群中所有節(jié)點(diǎn)
--initial-cluster-state new #表示從無(wú)到有搭建 etcd 集群
--discovery-srv #用于 DNS 動(dòng)態(tài)服務(wù)發(fā)現(xiàn)，指定 DNS SRV 域名
--discovery #用于 etcd 動(dòng)態(tài)發(fā)現(xiàn)，指定 etcd 發(fā)現(xiàn)服務(wù)的 URL
etcd總共有兩種集群模式:
- 單節(jié)點(diǎn)(Standalone);
- 多節(jié)點(diǎn),多節(jié)點(diǎn)的話(huà),因?yàn)楣?jié)點(diǎn)數(shù)必須是奇數(shù)個(gè),所以最小集群通常是3節(jié)點(diǎn).
etcd在windows下面有三種啟動(dòng)方式:
- 將參數(shù)直接輸入到命令行里,然后通過(guò)命令行或者bat啟動(dòng);
- 將參數(shù)寫(xiě)入到y(tǒng)ml配置文件里面,通過(guò)命令行或者bat啟動(dòng);
- 運(yùn)行在docker下面了.

需要注意的是,Docker環(huán)境下,如果要本機(jī)訪問(wèn),不能夠使用127.0.0.1,Docker其實(shí)就是一個(gè)Linux虛擬機(jī),所以如果要本機(jī)容器之間進(jìn)行訪問(wèn)的話(huà),那么就得用host.docker.internal來(lái)替換127.0.0.1,或者是創(chuàng)建一個(gè)網(wǎng)橋.
以上的命令,我都已經(jīng)形成了一個(gè)bat文件,下面提供下載:
