安装 Etcd
说明
Zebra 使用 Etcd 作为注册中心,版本为 3.1.7。
本指导只提供安装单机版的 Etcd 的相关指导,实际生产环境需使用Etcd Cluster 模式,具体安装步骤请参考 Etcd 官方网站。
下载
点击 https://github.com/etcd-io/etcd/releases/download/v3.1.7/etcd-v3.1.7-linux-amd64.tar.gz 下载 Etcd。
上传
上传下载的 Etcd 到 /tmp 目录,然后执行如下命令。
mkdir -p /opt/zebra/etcd
tar xzvf /tmp/etcd-v3.1.7-linux-amd64.tar.gz -C /opt/zebra/etcd --strip-components=1
rm -rf /tmp/etcd-v3.1.7-linux-amd64.tar.gz
添加配置
执行如下命令
mkdir -p /opt/zebra/etcd/conf
touch /opt/zebra/etcd/conf/etcd.conf.yml
把下面配置添加到 etcd.conf.yml 里面。 // TODO 要替换为github的链接,不直接贴配置。
