KBEC-00372 - Self-signed Apache certificate install


How to create and install self-signed Apache certificate on Electric Flow server.



  1. Generate a Private Key

         For such needs openssl tool can be used.

openssl genrsa –des3 –out server.key 2048

command above allow you to create your RSA Private Key, during the execution you’ll be prompted to enter a pass phrase for your key.

output of the command:

Generating RSA private key, 2048 bit long modulus



e is 65537 (0x10001)

Enter pass phrase for server.key:

Verifying - Enter pass phrase for server.key:


  1. Generate a Certificate Signing Request

         After private key is generated Certificate Signing Request can be generated. 

 openssl req -new -key server.key -out server.csr


You will be prompted for next information to input:

Country Name (2 letter code) [AU]:

State or Province Name (full name) [Some-State]:

Locality Name (eg, city) []:

Organization Name (eg, company) [Internet Widgits Pty Ltd]:

Organizational Unit Name (eg, section) []:

Common Name (e.g. server FQDN or YOUR name) []:

Email Address []:

Note: This CSR can be sent to Certificate Authority, who will verify identity of the requestor and issue a signed certificate.

  1. Remove Passphrase from key

By removing passphrase from certificate, we allow apache to not to ask it each time the service is started.

cp server.key server.key.org
openssl rsa -in server.key.org -out server.key

  1. Generate Self-signed Certificate


openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

  1. Backup your original Private Key and certificate

mv /opt/electriccloud/electriccommander/apache/conf/server.crt  /opt/electriccloud/electriccommander/apache/conf/server.crt.orig

mv /opt/electriccloud/electriccommander/apache/conf/server.csr  /opt/electriccloud/electriccommander/apache/conf/server.csr.orig

mv /opt/electriccloud/electriccommander/apache/conf/server.key  /opt/electriccloud/electriccommander/apache/conf/server.key.orig

  1. Copy newly generated Private Key and certificate

cp server.crt /opt/electriccloud/electriccommander/apache/conf

cp server.csr /opt/electriccloud/electriccommander/apache/conf

cp server.key /opt/electriccloud/electriccommander/apache/conf


Please make sure that these files have the same owner as all other files in electriccommander folder:
