多臺服務(wù)器搭建

wget -qO- https://binaries.cockroachdb.com/cockroach-v2.1.0.linux-amd64.tgz | tar  xvz
cp -i cockroach-v2.1.0.linux-amd64/cockroach /usr/local/bin

創(chuàng)建證書

mkdir certs my-safe-directory 
cockroach cert create-ca --certs-dir=certs --ca-key=my-safe-directory/ca.key
cockroach cert create-node localhost 0.0.0.0 --certs-dir=certs --ca-key=my-safe-directory/ca.key
#為root用戶創(chuàng)建證書(連接用，不必須)
cockroach cert create-client root --certs-dir=certs --ca-key=my-safe-directory/ca.key

啟動(dòng)多個(gè)節(jié)點(diǎn)

訪問adminUI

• 瀏覽器輸入ip地址加節(jié)點(diǎn)端口

命令行參數(shù)

如果指定了端口，使用命令行必須指定端口

#查看節(jié)點(diǎn)狀態(tài)  如果是默認(rèn)端口可以省略--port
cockroach node status --certs-dir=certs --port=11111
#進(jìn)入sql命令交互
cockroach sql --certs-dir=certs --port=11111

停止多有節(jié)點(diǎn)

pkill cockroach
