By default it's 1024 bits, but to make it harder to break I usually provides 4096. Fun part is with strength of the key -b 4096. t rsa means that it will be RSA key, but this is standard for creating SSH keys. Execute following command: ssh-keygen -t rsa -b 4096 In my case it's developer user so my command looks like this: ssh you'll be logged in (after providing the password), you can create RSA key pair.

Login via SSH to your server to account your created. It's much better to create separate user for system management and use only this account. Most probably you are using root account to execute all commands, but you should never ever login via SSH as a root. In order to create such user key-pair you first need to login to user you created. It makes life easier and you should use it if you want to login to different servers, use GIT etc.

How to setup SSH keys for new created user?Įach user should have RSA key-pair. You can use -shell and -no-create-home parameters separately:) Add -shell /sbin/nologin to disable login for given user, like so: sudo useradd httpd -shell /sbin/nologin -no-create-home It's nice if you want to cut of possibility to login to the system via SSH for instance. So in order to create user with no home directory use -no-create-home: sudo useradd httpd -no-create-homeĪnother useful feature is to specify shell of given user. This option is helpful when you are creating user for system service like Apache httpd for instance. It means that user will not have it's own place under /home directory to store it's files. There are lot of additional parameters for useradd command but there are two especially useful.įirst one is helpful when you don't want to create user home directory. sudo usermod -g wheel developer Optional parameters to useradd command Whoever belongs to this group can have sudo powers. wheel group is special group in CentOS configured in sudoers file. If you want to add this user sudo powers (and you should if you want to use this user instead of root), add it to wheel group. If you want to add developer user to www group created before use usermod command: sudo usermod -g www developer

Let's create new user developer that we mentioned at the beginning: sudo adduser developerĪnd create the password for his account: sudo passwd developer If you wish to delete the user, but to keep his files, omit this flag. r flag will remove also his home directory. In case you would like to remove any user from the system, use following command: sudo userdel -r USERNAME_TO_REMOVE In order to create such list you can use getent too: getent passwd > /etc/initial-users-listĬat /etc/initial-users-list Delete user from CentOS Same like with group, I like to have list of initial users. In order to create such group execute following command: sudo groupadd www Create list with available users I usually add group named It makes life easier with writing to files. In order to create group you need to use groupadd command: sudo groupadd NAME_OF_THE_NEW_GROUP If you need to remove group from CentOS simply use following command: sudo groupdel NAME_OF_THE_GROUP_TO_DELETE Create new group getent group > /etc/initial-group-listĬat /etc/initial-group-list Remove group from the system

It might be helpful after some time when you need to decide if given group was at the beginning or can it be safely removed. It's also handy to check which users belongs to that groups. If you are on fresh system it's handy to create a list with all available groups. access to sudo command for management tasks.logging via SSH instead of using root account.I will show you how to organise groups and users in CentOS.Īs an example we will create account for user named developer.
