![]() ![]() If you only need to run one or some specific commands with your user on a regular basis, you may need to invoke them from scripts with root privileges without asking for a password, e.g. Then the setting we need should be placed in this. For example, I create a file for my linuxportal user. It's a good idea to choose a filename that refers to the settings in it so that we know what's in it later. For example: nano /etc/sudoers.d/linuxportal Of course, this requires root privileges, so let's run this as root. If you want to set up sudo to run different commands without a password, create your own file in /etc/sudoers.d/ library. Run Sudo commands without using a password In other cases, such as outside a ISPConfig, for a manually created user, or for a simpler installation, or for a LAMP server in the case of, of course, the login must be referenced in the sudoers file. ![]() This is not the case with sudo either, so if you are working with such a server environment, when you use sudo without a password, the web that "exists" with them ( x) users in the sudoers file. And since the SSH user created later for the web account - and with the same UID and GID - is further down the list ( / Etc / passwd file), so in many places the web ahead ( x) is identified as a user. In this example, a Web4 user don't be fooled, it's just that ISPConfig"legacy" of the server environment because the control panel basically creates a web for each hosting account ( x) SSH user to perform the necessary maintenance and background tasks of the given website in the system. The first time you use it, it also prints out the short policy and then asks for the user's own password. sudo group membership, or the password setting in the sudoers file in case of): etc/sudoers.d/ directory, which we can also see at the end of the file to read its contents, so it executes our own configuration files in the directory.īy default, if the user is not set to run commands without a password, it will of course ask for the password if we are authorized to use sudo in any way (e.g. You can also see examples of its use here, and at the beginning of the comments he suggests that you consider creating your own files instead of modifying this file. # See sudoers(5) for more information on "#include" directives: # Allow members of group sudo to execute any command # See the man page for details on how to write a sudoers file.ĭefaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Please consider adding local content in /etc/sudoers.d/ instead of ![]() # This file MUST be edited with the 'visudo' command as root. If we look at the file, we see this in a "factory" Debian 10 (Buster) system: This file is never edited directly, but is used for this purpose visudo command: The file typically contains entries such as who can run which command (s) using sudo, and so on. The sudoers fileĪ / Etc / sudoers file contains the rules that the sudo command takes into account when using it. It allows you to delegate tasks such as the entire server or some of its services (e.g. Sudo is a useful little tool on Unix-like operating systems that allows you to run commands or programs on behalf of other users, typically as root. In this short description, we will look at how to persistently avoid asking for a password when using sudo. And if you also want to use commands running with root privileges in Shell scripts, you definitely need to avoid typing passwords so that our programs can run automatically. Also, if you work with multiple users, you will need our passwords more often. Although the session "remembers" the previously entered password for a while, we don't have to retype it for a while, but we need to re-identify ourselves after a while. When you often need the sudo by using other commands as root you may need to not have to type the password every time. Run Sudo commands without using a password. ![]()
