Singapore Cmi Vps Control Panel Operation Tutorial And Common Function Configuration Guide

steps: 1) open a browser and access the provider control panel address (example: https://panel.cmi.sg).
2) enter the registration email and password. if there are two factors, enter the verification code as prompted.
3) after logging in, check the account information at the top to confirm the billing status and remaining balance. if you cannot log in, click "forgot password" and follow the email prompts to reset.

steps: 1) enter the dashboard to view the current number of vps and cpu/memory/bandwidth usage.
2) click an instance name to enter the instance details page, where you can see ip, image, disk, snapshot and other information.
3) it is recommended to familiarize yourself with the top navigation (instance/image/snapshot/network/billing/work order).

steps: 1) click "create instance" or "new vps".
2) select the region (select the singapore computer room), instance specifications (cpu, memory, disk, bandwidth), and image (ubuntu/centos/windows).
3) configure the network (assign a public ip or use a private network), set the login method (password or ssh key), set the host name, click "create" after confirming the billing cycle and wait for the deployment to complete.

steps: 1) find the target instance in the instance list and click the operation menu on the right.
2) select "start" or "shut down" or "reboot". please use caution if "forced shutdown" is used.
3) wait for the control panel to display status change (running/stopped). if the status is abnormal, check the console log.

steps: 1) use the "console" function of the control panel to quickly enter the instance (applicable when there is no public network or network failure).
2) if you use ssh: select or upload the public key when creating, copy the public ip of the instance, command: ssh -i /path/to/key root@ip.
3) if you use a password to log in, it is recommended to change the password and add an ssh key immediately after logging in for the first time.

steps: 1) enter the "network" or "security group" page to create a new rule or edit an existing rule.
2) common allowed ports: 22 (ssh), 80 (http), 443 (https); restrict source ip to improve security.
3) after saving and applying the rules, test the port from the external network (telnet ip port or nmap).

steps: 1) check the disk information in the instance details. if you need to expand the capacity, select "extend disk" in the panel, follow the prompts to expand the capacity online and adjust the partitions in the system.
2) it is recommended to create snapshots regularly: click "create snapshot" and fill in the description. after the snapshot is completed, it can be used to roll back or clone a new instance.
3) confirm the billing and storage policy before downloading or exporting snapshots.

steps: 1) select "reinstall system (reinstall)" or "replace image" in the instance operation.
2) select the target system image, set the initial account (root or ubuntu) and login method (password/ssh public key), and start reinstallation after confirmation.
3) reinstallation will clear the disk, so please take a snapshot or back up key data in advance.

steps: 1) if you need a fixed public ip, apply for an elastic public ip (eip) and bind it to the instance.
2) if intranet multi-instance interconnection is used, configure the private network subnet and assign ip, and check the routing table and security group policy.
3) port forwarding (nat) is often used to map external network ports to private network instances. follow the panel prompts to add rules and test connectivity.

steps: 1) enable monitoring (cpu/memory/disk/bandwidth) indicator collection and set alarm thresholds (such as cpu>80%).
2) automatic expansion or email/sms notification can be configured when an alarm is triggered.
3) if the upper limit is reached frequently, click "adjust configuration" to upgrade instance specifications online or increase disk/bandwidth.

steps: 1) check the current fees, consumption details and expiration time in "billing", and set automatic renewal to avoid instance interruption.
2) in case of abnormal deduction or network/instance failure, first check the control panel notification and status page, and then submit a support ticket with error screenshots and instance ids.
3) for urgent issues, you can use online customer service or telephone support, and mark the priority in the work order.

q: what are the security initialization steps to be done immediately after creating a new singapore cmi vps?

answer: recommendations: 1) update the system immediately (apt update && apt upgrade or yum update); 2) disable root password login and use ssh keys instead; 3) configure the firewall (ufw or iptables) to only open necessary ports; 4) create a non-root administrator user and grant sudo; 5) install fail2ban and configure login failure ban rules.

q: after expanding the disk in the control panel, how can i adjust the partition and file system in the system without loss?

answer: steps: 1) complete the disk expansion in the control panel and confirm that the instance has recognized the new capacity; 2) log in to the instance and use lsblk to view the disk devices; 3) if it is lvm, execute pvresize && lvextend && resize2fs (or xfs_growfs); 4) if it is not lvm, use growpart to adjust the partition and then resize2fs; 5) be sure to take a snapshot backup before operation.

q: the vps cannot be accessed from the public network. how to troubleshoot the problem in order?

answer: troubleshooting sequence: 1) confirm that the instance status is running; 2) check whether the public ip is correctly bound on the control panel; 3) check whether the security group/firewall has opened the corresponding port; 4) use netstat/ss in the instance to check whether the service is listening; 5) check the operating system routing and iptables rules; 6) if it is still abnormal, check the console log and submit a work order to request computer room network troubleshooting.
