problems with installation?

[Ron-e]

I am re-installing Sentora because i want to give CentOS 7 a new chance, but i got these messages.
Maybe i am reading them wrong but this isn't good wright?

Code:

setenforce: SELinux is disabled
Redirecting to /bin/systemctl stop  sendmail.service
Failed to issue method call: Unit sendmail.service not loaded.
error reading information on service sendmail: No such file or directory
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
Redirecting to /bin/systemctl stop  firewalld.service
Failed to issue method call: Unit firewalld.service not loaded.
error reading information on service firewalld: No such file or directory

P.S. postfix ERROR still exists in my install:

Code:

-- Installing Postfix
ERROR 1071 (42000) at line 115: Specified key was too long; max key length is 1000 bytes

edit: Forgotten to mention that i used the following line to install:

Code:

cd \tmp && yum install wget -y && wget https://raw.githubusercont
ent.com/sentora/sentora-installers/master/ovh-soyoustar-kimsufi-postinstall.sh &
& sudo bash ovh-soyoustar-kimsufi-postinstall.sh
