我有三台云服务器(centos7.2 64位),采用内网IP配置SSH互信。
执行总是报错如下:
ssh - keygen -t rsa -P
ssh: Could not resolve hostname -: Name or service not known
其中,hostname采用命令:
hostnamectl set-hostname bzg001设置
/etc/hostname也改了:
bzg001
/etc/hosts也设置了:
127.0.0.1 bzg001 localhost
172.27.0.14 bzg001 localhost
172.27.0.2 bzg002
写在前面:相同代码在阿里云相同配置相同操作系统和内核版本的机器运行过一遍,没有报错并成功启动 docker
按照这里(https://docs.docker.com/install/linux/docker-ce/centos/#install-docker-ce-1)安装的, 最后运行:
[xiaotao@VM_0_12_centos docker]$ sudo systemctl start docker
Job for docker.service failed because the control process exited with error code. See "
(一) 这就是指引????
我就想问问解压出来的文件,要放到服务器吧?(假如要放,放到哪里?我系统Centos7.2)

(二)上面的问题,初步解决。现在有新问题:
编辑ssl.conf重新启动 Apache:
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
不编辑,提示证书风险。

为什么?
我现在需要在云服务器上部署activemq,但是启动的时候总是报
Failed to start Apache ActiveMQ (localhost, ID:VM_0_7_centos-41389-1542077095783-0:1) | org.apache.activemq.broker.BrokerService | main
