check ssl private key and public key are matched

This is a tough question. How can I verify a SSL private key (e.g server.key) and a public key (e.g. server.crt) are matched. The steps are :

#openssl x509 -noout -text -in server.crt

Look for the string of modulus which is 1024 bit and then

#openssl rsa -noout -text -in server.key

Again, look for the string of modulus which should match exactly that of the previous step for the public key.

A sample of the modulus of my server certificate is as follows:

Public Key Algorithm: rsaEncryption
RSA Public Key: (1024 bit)
Modulus (1024 bit):
