You have to enabled services to start during restart server.

# systemctl enable sshd.service

For iptables you have to allow for 22 port.

Did you read the messages? They tell you what is wrong. You have previously connected to this ip address and stored its ssh key fingerprint. Now you are connecting again and ssh is warning you that the fingerprint has changed. Either you have reinstalled the system, it's not the system you thought it was or someone has compromised your target machine and changed its ssh key.

Sorry, it should be :

For check services runlevel
# chkconfig --list

For set sshd servces run during start system
# chkconfig --level 3 sshd on

This may or may not work. You should allow for other runlevels:

Code: Select all

# chkconfig sshd on
In the case of sshd, this will turn it on for runlevels 2, 3, 4 and 5
