Prerequisites
- The ECS status is Running.
- The ECS must have a remaining space of more than 300 MB, and data can be written to its root directory.
- SELinux affects the password reset plug-in of Linux ECSs. You can disable it by referring to Disabling SELinux.
- ECSs created using a SUSE 11 SP4 image must have 4 GB or a larger memory.
- DHCP must be enabled for the VPC used by the ECS.
- Networks of the ECS are normal.
- The outbound security group rule of the ECS must meet the following requirements:
- Protocol: TCP
- Port Range: 80
- Remote End: 169.254.0.0/16
If you use the default outbound security group rule, preceding requirements can be met, and the ECS can be initialized. The default outbound security group rule is as follows:
- Protocol: All
- Port Range: All
- Remote End: 0.0.0.0/16
Procedure
- Check whether the one-click password reset plug-in has been installed on the ECS.
- Log in to the ECS as user root.
- Run the following command to check whether CloudResetPwdAgent has been installed:
Check whether the obtained information is similar to that shown in Figure 1.
- If yes, the plug-in has been installed.
- If no, the plug-in has not been installed. Then, install it.
- Download CloudResetPwdAgent.zip and verify its integrity by referring to Obtaining the One-Click Password Reset Plug-in (Linux).
