I'm learning to work with linux but it isn't working out
Script 1, did work until I updated opensuse:
#!/bin/bash
useradd Test
passwd Test123
mkhomedir_helper Test
(It now says that all these commands don't exist)
Script 2, I can only get into my MySql console and he doesn't execute everything:
#!/bin/bash
mysql -u root -ppassword
sleep 3
CREATE USER 'Test'#'localhost' IDENTIFIED BY 'password'
I would really appreciate some help here since I'm new to linux
Run following cmd:
echo $PATH
Output should be list some paths as below
/Usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
If not then run below command:
export PATH="/Usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"
Now try running above script-1, if it still gives same error, then you are missing some packages, install 'pam' package which contains mkhomedir_helper binaries, so run following command to install pam.
zypper in pam
Script 2, to run mysql query from command line or as a shell script you need to use '-e' option, change the script 2 as below:
#!/bin/bash
mysql -u root -ppassword -e 'CREATE USER "Test"#"localhost" IDENTIFIED BY "password"'

We have a password less authentication between the server for root user, I am trying to run the alias on remote server as below
#ssh remoteserver runuser -l wasadmin wasstart
But it is not working. Any suggestions or any other method to achieve it
Based on your comments as you need to sudo to wasadmin in order to run wasadmin, you can try this:
ssh remoteserver 'echo /path/to/wasadmin wasstart | sudo su - wasadmin'
For add an alias in linux you must run
alias youcommandname=‘command’
Notice:
This will work until you close or exit from current shell . To fix this issue just add this to you .bash_profile and run source .bash_profile
Also your profile file name depending on which shell you using . bash , zsh ,...
I am creating a script meant to be run as superuser that reads a file and runs a number of scripts on behalf of all users. The important bit is this:
sudo -u $user -H source /home/$user/list_of_commands
However, whether I encose the command with quotesor not, this fails with:
sudo: source /home/user/list_of_commands: command not found
I have even tried with the . bash builtin:
sudo: . /home/user/list_of_commands: command not found
Of course running source outside a sudo environment works. I thought there might be a PATH problem, and I tried to bypass it by providing the full path to source. However, I cannot find the executable: which source returns which: no source in (/usr/local/sbin:usr/local/bin:usr/bin). So I'm stuck.
How do I make a script source a file as a user?
source is a builtin not a command, use it with bash -c:
sudo -u $user -H bash -c "source /home/$user/list_of_commands"
Logging via terminal I can switch to root user fine:
ubuntu#ip-10-0-0-70:~$ sudo -s
root#ip-10-0-0-70:~# whoami
root
So I created in rundeck a job script with this:
whoami;
echo "1st step";
sudo -s;
echo "2nd step";
And when I run this, it prints:
ubuntu
1st step
After print '1st step' it get stucked forever. Seems a problem with sudo -s command.
tried sudo -i but the same happens
tried sudo su - root but the same happens
rundeck is logging as ubuntu user, me too
any idea to switch to root in rundeck script?
This is the expected behaviour.
You are running a shell via 'sudo -s' and then not leaving/exiting it ! So it waits forever for somethig that won't come.
You can probably add 'sudo' as an Advanced option of your script (where it says "Run script with an interpreter or prefix. E.g.: sudo, time:").
But it will run your whole script as root.
If you just want a specific command to be run as root , just prefix your command with sudo as so:
sudo "enter_your_command_to_be_run_as_root_here"
Entering the command prefixed by Sudo will generate the following error on most linux distributions.
sudo: sorry, you must have a tty to run sudo
You can enable sudo without tty by running 'visudo' and commenting out the defaults line or removing 'requiretty' from the defaults line.

How to write script that use sudo su and run all command in script below it.
You have several options.
You can just move the sudo command outside of your script, and have people call it like this:
sudo -u team /path/to/your/script
You can put the sudo command in one script and the actual commands you want to run with elevated privileges in another script. That is, people run your_script, which looks like:
#!/bin/sh
sudo -u team /path/to/your_script.real
And your_script.real contains the commands that you want to run with elevated privileges.
If you really want everything in the same script and you don't mind being a little too clever, you can have the script check re-execute itself using sudo like this:
#!/bin/sh
TEAM_UID=500 # replace with correct uid
if [ "$UID" != $TEAM_UID ]; then
exec sudo -u team $0
fi
And you can also feed commands to a shell from stdin, like this:
#!/bin/sh
sudo su - team <<'EOF'
echo my uid is $UID
EOF
You could try having all of the commands on the same line and seperate them with ';'.
eg. 'sudo su; somecommand; another command'
Could also run that script as the intended user.
When I run a script such as this:
ssh -t root#10.10.10.10 '/tmp/somescript.sh'
where the script is defined as:
#!/bin/sh
mkdir -p /data/workday/cred
chown -R myuser:myuser /data
su myuser - # <------- NOTICE THIS ! ! ! !
rpm -Uvp --force --nodeps --prefix /data/place /data/RPMs/myrpm.rpm
Notice the above su command.
If I comment-out the su command, the script runs remotely and then my shell prompt returns to where I came from ( same server where I ran the ssh command above )
But leaving the script as listed above, causes the script to complete successfully but the shell prompt stays on the remote server.
How can I prevent that ? Making sure that the issuer of the rpm command is a different user than root just a listed ?
But leaving the script as listed above, causes the script to complete successfully but the shell prompt stays on the remote server.
Not exactly. The script is running up to the su command, which spawns a new subshell, and stopping there until you exit the shell. Until you exit that shell, the rpm command never runs, and when it does, it runs as root.
If you want to run the rpm command as a non-root user, you'd need to do something a little different, like:
sudo -u myuser rpm -Uvp ...
add 'exit' at the end of your script
