Premise:The cloud server can logging by local method(like VNC),but remote logging is unavailable.The cloud server can’t log in by SSH,or by remote tools like Cloudshell,Xshell.How to solve the problem?<\/p>\n\n\n\n

First,log in the cloud server by correct usermane and password.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This is the checklist to solve the problem:<\/p>\n\n\n\n

1.Input ‘systemctl status sshd<\/strong>‘ in the cloud server to check the sshd service.When the sshd is inactive,you can input ‘systemctl start sshd<\/mark><\/strong>‘ to restart sshd.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

When sshd service can’t start nomally,and output wrong imformation.Input ‘systemctl status sshd’ to check the details.<\/p>\n\n\n\n

2.Check configuration files.Configuration files are \/etc\/ssh\/ssh_config <\/mark><\/strong>and \/etc\/ssh\/sshd_config<\/strong>.Before checking files,you can close SELinux and firewall,or manage ports of SELinux,or release ports of firewalld.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Check the file \/etc\/ssh\/sshd_config<\/mark><\/strong>.<\/p>\n\n\n\n

Permit root account login.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This part control IP addresses and port of sshd.The default port of sshd is 22.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After modification of sshd configuration file.Input ‘systemctl restart sshd’ to restart sshd service.<\/p>\n\n\n\n

3.Input ‘netstat -tnlp |grep sshd<\/strong>‘ to check status of ports.The port 22 must be listening.If port 22 is not listening,check sshd service or configuration file.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

4.Check ports of security group and configure security group rule.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Choose your security group and configure ports.You can add,modify,delete rules by this page.There inbound rules and outbound rules.A rule contain protocol,port,description,and so on. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The default port of ssh is 22,port 22 must be released.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

If port 22 is not exist,click ‘Add Rule’ to release port 22.<\/p>\n\n\n\n

5.Access Elastic IP address(EIP).When the webserver is running(like apache,nginx,and so on),you can visit the Elastic IP address of cloud server.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n\n

After checking,you can login and visit your cloud server by ssh.You can input ‘ssh “username”@”EIP”‘ in your windows ‘cmd’ page.There are many remote tools like Cloudshell,Xshell,and so on.You can login remotely by these tools.<\/p>\n\n\n\n
