Restart Service Sshd

Posted on  by 



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. 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’.

  1. Restart Service Sshd Mac
  2. Dss 5027 Codes
  3. Restart Sshd Service Ubuntu
  4. Ubuntu Restart Sshd Service
  5. Linux Restart Sshd Service

Example:

You should not 'need' to run your application as user 'daemon' or 'systemd'. Instead, run your app as the user it was designed for. If running 'as' daemon/systemd seemed to solve your problem, you merely found an incorrect workaround (and the true problem probably relates to permissions, see 'ExecStartPre=' if I were to take a guess at your root issue) – Scott Prive Jul 1 '20 at 15:02. Sudo systemctl restart ssh sudo service ssh restart The service is also controlled by upstart, and not sysvinit. So you'll find it at /etc/init/ssh.conf instead of /etc/init.d/ssh. If you want to change some settings (e.g., the listening port, and root login permission) by editing the configuration file via command. 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:. In this article. Linux virtual machines (VMs) in Azure are usually managed from the command line using a secure shell (SSH) connection. When new to Linux, or for quick troubleshooting scenarios, the use of remote desktop may be easier.

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

“/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.

[root@server]# /etc/init.d/sshd restart
-bash: /etc/init.d/sshd: No such file or directory
CentOS 7 servers have systemd so the commands are entirely different and these commands will not work on server with CentOS 6 and older versions. You must make sure the OS is version 7 before running the below commands.

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
* sshd.service – OpenSSH server daemon
Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled; vendor preset: enabled)

Active: inactive (dead) —> If the status shows “inactive (dead)” then it means SSH service is not running on this server

Restart Service Sshd Mac

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

Dss 5027 Codes

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

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

Restart sshd service redhat 7

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

In the below server you can see that process ID of SSH service is 221572, killing this process will stop SSH service and you will get disconnected from the server.
[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.

Restart Sshd Service Ubuntu

Restart Service Sshd

Enable SSH service : systemctl enable sshd

Disable SSH service : systemctl disable sshd

Ubuntu Restart Sshd Service

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

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

Linux Restart Sshd Service


active

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

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