使用Consul

Consul集群的每个节点都必须先安装Consul.安装非常容易,Consul发布为所支持的平台和架构的二进制包.这个指南不包含从源代码编译Consul的内容.

安装Consul

安装Consul,找到适合你系统的包下载他.Consul打包为一个'Zip'文件.

下载后解开压缩包.拷贝Consul到你的PATH路径中,在Unix系统中~/bin和/usr/local/bin是通常的安装目录.根据你是想为单个用户安装还是给整个系统安装来选择.在Windows系统中有可以安装到%PATH%的路径中.

OS X

如果你使用homebrew作为包管理器,你可以使用命令

brew install consul

来进行安装.

完成安装后,通过打开一个新终端窗口检查consul安装是否成功.通过执行 consul你应该看到类似下面的输出

[root@hdp2 ~]# consul

    agent          Runs a Consul agent
    configtest     Validate config file
    event          Fire a new event
    exec           Executes a command on Consul nodes
    force-leave    Forces a member of the cluster to enter the "left" state
    info           Provides debugging information for operators
    join           Tell Consul agent to join cluster
    keygen         Generates a new encryption key

    version        Prints the Consul version
