It is possible to check SSL installation by using this online tool: https://decoder.link/sslchecker/.
SSL certificate installation via Zimbra Certificate Manager (command line interface)
A Zimbra package has the zmcertmgr tool to manage SSL certificates.
For version 8.6 or lower, this tool must be run as root. Run this command in the terminal to switch from the default user to the root:
sudo ស៊ូ
Starting from version 8.7 this tool should be run as zimbra user.
Run these commands to switch from the default user to the zimbra user:
sudo ស៊ូ
su zimbra
1) To start the installation process, you need to upload the SSL certificate file (server_domain_com.crt) and CA bundle file (server_domain_com.ca-bundle) to any folder to your hosting server on the temporary basis. For this example, SSL files have been uploaded to the /opt/ directory.
2) Verify that your certificate received from the Certificate Authority matches the private key generated along with the CSR: /opt/zimbra/bin/zmcertmgr verifycrt comm
/opt/zimbra/ssl/zimbra/commercial/commercial.key /opt/server_domain_com.crt /opt/server_domain_com.ca-bundle
The output should look like:
You can also download them, as well as your server certificate, from your 1Byte account. The root and intermediate certificates will be in the .ca-bundle file. Save them in separate files using any plain text editor (e.g., Notepad or TextEdit). The first and the second certificates in the file are intermediate certificates, and the last one is the root certificate.
3) Deploy your commercial certificate.
/opt/zimbra/bin/zmcertmgr deploycrt comm /opt/server_domain_com.crt /opt/server_domain_com.ca-bundle
The successful output should look like:
4) Verify that the correct certificate has been deployed.
/opt/zimbra/bin/zmcertmgr viewdeployedcrt
For example, the details of the PositiveSSL certificate will look like:
5) To apply changes, you need to restart Zimbra services like zimbra user:
sudo ស៊ូ
su zimbra
Once the default user is switched to zimbra user, run this command to restart services:
zmcontrol ចាប់ផ្តើមឡើងវិញ
When all services are restarted, new SSL certificate details can checked by using this online tool: https://decoder.link/sslchecker/.
