rex ssh公钥认证

认证:前面的示例中我们演示了怎么通过用户名密码登陆,其实也可以用秘钥认证使用密钥认证只需要在Rexfile里定义你的公钥和私钥既即可:user "my-user";private_key "/home/user/.ssh/id_rsa";  ##私钥public_key "/home/user/.ssh/id_rsa.pub"; ##公钥key_auth;[root@node01 my-first-rex-project]# cat Rexfileuse Rex -feature => ['1.0'];user "root";private_key "/root/.ssh/id_rsa";  ##私钥public_key "/root/.ssh/id_rsa.pub"; ##公钥key_auth;group myservers => "192.168.137.3";desc "Get the uptime of all servers";task "uptime", group => "myservers", sub {   my $output = run "uptime";   say $output;};desc "Start Mysql Service";task "start_mysql", group => "myservers", sub {    service "mysql" => "start";};[root@node01 my-first-rex-project]# rex uptime[2017-04-29 10:16:24] INFO - Running task uptime on 192.168.137.3 01:18:43 up 21:46,  1 user,  load average: 0.00, 0.00, 0.00[2017-04-29 10:16:35] INFO - All tasks successful on all hosts[root@node01 my-first-rex-project]#
