[Help(T_T)] Install error : Failed on Install st2 dependencies ( MongoDB )

I tried to install St2 with one-line command suggested on stackstorm website following that:

curl -sSL https://stackstorm.com/packages/install.sh | bash -s – --user=xxxx --password=‘xxxx’

An error occured on MongoDB start after installation.

Startting mongod: [failed]
############# ERROR #################

Failed on install st2 dependencies (MongoDB)

#####################################

why this occured?

I tried uninstall everything and install again.

However, It doesn’t work…

(T_T)

Basically, I didn’t edit conf files.

OS version :CentOS6.7

Please post the whole error, or the whole output from the install script.

The one-line install script does expect to be run on a “clean” CentOS installation.
