Restoring the Root Certificate Imported to MEF Center

Log in to the MEF Center device environment as the root user.
Run the following command to go to the directory where run.sh is stored. The default installation directory is /usr/local/MEF-Center/mef-center.
```
cd Installation_directory/MEF-Center/mef-center
```

Run the following command to restore the backup root certificate:

./run.sh restorecert -name=Certificate_name

**Table 1** restorecert parameters
Parameter	Description
name	(Mandatory) Certificate name. Values: north: certificate of the integrated platform software: software repository certificate image: image repository certificate

If the following information is displayed, the command is successfully executed:

restore unused certificates of [north] ca successfully

After the certificate is restored, the current certificate is replaced with the backup certificate. After the certificate of the integrated platform is restored, you need to restart MEF Center for the certificate to take effect. After the software/image repository certificate is restored, it takes about 5 minutes for the certificate to take effect.
