HOW TO RESTART SSH SERVICE ON CENTOS 6 / RHEL 6 server

In order to run an OpenSSH server, you must have the openssh-server installed (see Section 8.2.4, “Installing Packages” for more information on how to install new packages in Red Hat Enterprise Linux 6).

• The next thing you’ll need to do on your server is to configure the disabled ssh-agent service to automatically start and also configure the sshd service to automatically start. To do this, run the following PowerShell commands: Set-Service -Name ssh-agent -StartupType ‘Automatic’ Set-Service -Name sshd -StartupType ‘Automatic’.
• If you want to start, stop, restart, enable, reload & check the status of the service follow the below commands to do it. Either root or sudo Authorization required to run the below commands. All the services is available “/etc/init.d/. 1) To Start OpenSSH service. Use the below commands to start the OpenSSH server in Linux.
• This video demonstrates how to reboot your server over SSH.The big thing to know if that if you’re logged in as the “root” — most powerful — user on the syst.

1 . Log into your CentOS Server as ‘root’ user

2. Run the command ‘service sshd restart’ to restart SSH service

Command 1 : service sshd restart

OR

command 2 : /etc/init.d/sshd restart

You can either use the command “service sshd restart” OR “/etc/init.d/sshd restart” to restart SSH service. There is no need to run both commands.

[root@server ~]# service sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]

[root@server ~]# /etc/init.d/sshd restart
Stopping sshd: [ OK ]
Starting sshd: [ OK ]

HOW TO STOP SSH SERVICE ON CENTOS/REDHAT 6 SERVERS

Do the below steps to stop SSH service on linux server.

IMPORTANT : You might get disconnected from the server if you stop SSH service on your server. You can safely stop SSH service only if you have console access to the server.

Command to stop SSH service on centOS/RHEL linux server is given below.

1. Log into your linux server via SSH as ‘root’ user

2. Run the command ‘service sshd stop’ to stop SSH

Command 1 : /etc/init.d/sshd stop

OR

Command 2 : service sshd stop

root@server [~]# /etc/init.d/sshd stop
Stopping sshd: [ OK ]

OR

root@server [~]# service sshd stop
Stopping sshd: [ OK ]

HOW TO START SSH SERVICE ON CENTOS/REDHAT SERVERS

Commands to start SSH service on Linux Server is given below.

1. Log into your linux server as root user

2. Run the command ‘service sshd start’ to start SSH service

Command 1 : /etc/init.d/sshd start

OR

Command 2 : service sshd start

root@server [~]# /etc/init.d/sshd start
Starting sshd: [ OK ]

OR

root@server [~]# service sshd start
Starting sshd: [ OK ]

HOW TO CHECK THE STATUS OF SSH SERVICE

Run the command ‘service sshd status’ to check the current status of SSH service. This command will show whether SSH service is running or stopped on your linux Server.

The below shows that SSH service is running fine on the server.

Command : service sshd status

OR

Command : /etc/init.d/sshd status

root@server [~]# service sshd status
openssh-daemon (pid 14945) is running…

root@server [~]# /etc/init.d/sshd status
openssh-daemon (pid 14945) is running…

‘14945’ is the process ID of the SSH process. Killing this process ID will stop SSH service and you will get disconnected from the server.

If the SSH service is down on the server it will show “openssh-daemon is stopped”

“openssh-daemon is stopped” is stopped means the service is not running on your server. You can run the command “service sshd start” to start the service. You must check the server logs if you are unable to start the service.

If you have any webhosting control panels installed (like cPanel, plesk etc) then you can try restarting the service from frontend panel.

You must have server root login details to restart SSH service. The server login details will be provided by your webhosting company/Datacenter. You can log into the server using putty software. Putty software can be downloaded from the website putty.org and you can connect to your server via SSH. Boot camp and parallels for mac. Use systemctl command instead of ‘service’ command to restart service on CentOS 7 and RHEL 7 servers. RHEL 7 and CentOS 7 migrated to Systemd and commands like ‘service’ and ‘chkconfig’ is now done using ‘systemctl’.

Example:

In the above CentOS 7 server you can see that “service sshd restart” command gets redirected to new command “systemctl restart sshd.service”. SSH Service is restarted but it shows from now on you should use “systemctl” command to restart instead of using ‘service’ command.

Start Openssh Server

“/etc/init.d/sshd restart” command will not work on centOS 7 servers. You will see the below error if you try to restart using that command.

HOW TO RESTART SSH SERVICE ON CENTOS 7 / RHEL 7 server

Do the below steps to restart SSH service on CentOS 7 / Redhat 7 Servers.

1. Log into your Linux Server via SSH as ‘root’ user

2. Run the command ‘systemctl restart sshd.service’ to restart SSH

Command 1 : service sshd restart

OR

Command 2 : systemctl restart sshd.service

root@server [~]# service sshd restart
Redirecting to /bin/systemctl restart sshd.service

root@server [~]# systemctl restart sshd.service
root@server [~]#

HOW TO CHECK STATUS OF SSH SERVICE ON CentOS 7 / RHEL 7 server

The below commands can be used to check the current status of SSH service, it will show whether the service is active or inactive.

1. Log into your Linux server as ‘root’

2. Run the Command ‘systemctl status sshd.service’ to check status of SSH service.

Command 1 : service sshd status

OR

Command 2 : systemctl status sshd.service

root@server [~]# systemctl status sshd.service

HOW TO START SSH SERVICE ON CENTOS 7 / REDHAT 7 SERVERS

Run the below command to start SSH service (if the service is not running)

1. Log into Linux server as root user

2. Run the below command to start SSH service

Command 1 : systemctl start sshd.service

OR

Command 2 : service sshd start

HOW TO STOP SSH SERVICE ON CENTOS 7 / REDHAT 7 SERVERS

Ssh Server For Windows

Run the command ‘systemctl stop sshd.service’ to restart SSH service.

NOTE : The below commands will stop sshd service on your server and you might get disconnected from SSH. Run this command only if you have console access so that you can start the service.

Command 1 : service sshd stop

OR

Command 2 : systemctl stop sshd.service

root@server [/]# systemctl stop sshd.service

OR

root@server [/]# service sshd stop
Redirecting to /bin/systemctl stop sshd.service

[root@server /]# ps aux | grep ssh
root 221572 0.0 0.0 64348 1180 ? Ss Jan26 0:55 /usr/sbin/ssh

Command to kill the above SSH process : kill -9 221572

chkconfig commands will not work on centOS 7 servers so you must use the below commands to enable and disable the SSH service in the runlevel.

Enable SSH service : systemctl enable sshd

Disable SSH service : systemctl disable sshd

Run the below commands to check whether SSH service is enabled and active

[root@server ~]# systemctl is-failed sshd.service
active

[root@server ~]# systemctl is-active sshd.service
active

[root@server ~]# systemctl is-enabled sshd.service
enabled
