Fabio(Go 语言):https://github.com/eBay/fabio

Fabio 是一个快速、现代、zero-conf 负载均衡 HTTP(S) 路由器,用于部署 Consul 管理的微服务。

Fabio 由 eBay Classifieds Group 开发,用于处理 marktplaats.nl 和 kijiji.it 的流量。Marktplaats 所有的流量都经过 Fabio ,每秒有 250000 个请求,分发于数个 Fabio 实例,并且没有出现任何延迟。

简单流程图(摘自 http://dockone.io/article/1567):

Mac OS 安装命令(如果没有安装 Consul,会自动安装):

$ brew install fabio

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local

already exists. You may want to remove it:
rm '/usr/local/bin/consul' To force the link and overwrite all conflicting files:
brew link --overwrite consul To list all files that would be deleted:
brew link --overwrite --dry-run consul Possible conflicting files are:
/usr/local/bin/consul
==> Caveats
If consul was built with --with-web-ui, you can activate the UI by running
consul with `-ui-dir /usr/local/Cellar/consul/0.7.2/share/consul/web-ui`. zsh completion has been installed to:
/usr/local/share/zsh/site-functions To have launchd start consul now and restart at login:
brew services start consul
Or, if you don't want/need a background service you can just run:
consul agent -dev -advertise 127.0.0.1
