How did you install and configure jicofo?

I start jicofo as below
./jicofo.sh --host=10.60.100.194 --domain=10.60.100.194 --secret=mysecret2 --user_domain=auth.10.60.100.194 --user_name=focus --user_password=mysecret3

the secret and user_name and user_password had been registered in prosody .just as below:
prosodyctl cert generate 10.60.100.194
prosodyctl cert generate auth.10.60.100.194

生成秘钥

prosodyctl register focus auth.10.60.100.194 mysecret3

are there any problems ? could you give me some help ,thanks!
@saghul
