使用Clustershell搭建Kafka和Zookeeper集群
1、 安装环境
虚拟机环境，共有三台虚拟主机：
Router1 192.168.3.116
Router2 192.168.3.115
Router3 192.168.3.121
2、CMD工具
SecureCRT 7.2.3
具有Tile功能，可以将多个session窗口并列显示。
设置在菜单windows ->Tile Vertically，并且有显示 command windows功能.设置在菜单View -> Command windows.在command windows中可以右键设置 send commands to all sessions菜单，就可以在commandwindows中输入命令后向所有sessions发送输入的命令。
3、搭建zookeeper集群
3.1设置多台机器免密码
在command windows中输入命令
-bash-4.1# ls /root/.ssh known_hosts //删除原有文件 -bash-4.1# rm -rf /root/.ssh/* -bash-4.1# ls /root/.ssh //生成密钥文件 -bash-4.1# ssh-keygen -t rsa Generating public/private rsa keypair. Enter file in which to save the key(/root/.ssh/id_rsa): Enter passphrase (empty for nopassphrase): Enter same passphrase again: Your identification has been savedin /root/.ssh/id_rsa. Your public key has been saved in/root/.ssh/id_rsa.pub.
