复制这段内容后打开百度网盘手机App，操作更方便哦 [root@controller ~]# systemctl restart httpd.service memcached.service 测试：http://192.168.0.111/dashboard/ 八．创建双机相互信任 1.controller服务器 [root@controller ~]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 43:5e:57:44:68:d3:b2:89:57:39:a1:fd:43:c7:41:e4 root@controller The key's randomart image is: +--[ RSA 2048]----+	=B*		=+*..		. .oo*.Eo		o ...+ ...		S . ..		. .
