I'm using "Laravel Forge" and want to run sudo to create swap file, but it's failed because i cannot run sudo command from forge user. how to have root access or run sudo comment ?
When you provisioned your forge server an email was sent to you with the SUDO password. You can su or sudo using this password.
I'm using Amazon lightsail with forge.
I have a pem file provided by lightsail that allows access to the ubuntu user which has sudo without a password.
You can ssh in as ubuntu#<ip address> if you have the pem file.
ssh -i ~/.ssh/xxxxxxxxxxxx.pem ubuntu#xxx.xxx.xxx.xxx

I am trying to use Windows Docker to build a docker image. When building the docker image, it will invoke pip to access remote private GitHub repositories. However, it always returned this error message: git#github.com: Permission denied (publickey). fatal: Could not read from remote repository. It seems that the SSH agent key is not forwarded to Windows Docker container. I run it in Git Bash Windows.
My device information is:
Windows Version: Windows11
Docker Desktop Version: Docker Desktop 4.12.0 (85629)
WSL2 or Hyper-V backend? WSL2 backend
The main part of the Docker file is:
FROM python:3.8.13 as builder
RUN mkdir -p -m 0600 ~/.ssh && ssh-keyscan github.com >> ~/.ssh/known_hosts
RUN mkdir -p /home/app/
COPY requirements.txt /requirements.txt
RUN --mount=type=ssh pip install -r /requirements.txt --target
Then, running following commands to build the docker image:
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
docker build --ssh default .
When runningRUN --mount=type=ssh pip install -r /requirements.txt --target, the pip needs to access to private GitHub repositories and install them in docker image. But it always returned the permission denied error above - it seems that the ssh agent key is not visible/forwarded in docker container. I actually have already created a SSH key and added it to my GitHub.
I am just wondering if I missed something? Or it may be an underlying issue with Windows Docker? Thank you!
I don't have access to my sudo password anymore, and whenever I try to download anything it always asks for the pass. Is there any way I can either see what my password is or just remove the sudo password altogther?
I've installed Centos7 on the Google Cloud Platform, as you know there is just ssh option to connect to the machine.
Now I need to have access to its desktop(GUI) from my laptop (it's win10).
it's appreciated if anyone can help me.
Thanks in advance
you need to ssh login into your CentOS machine either from ssh button in Gcloud, or using the cloud shell:
gcloud compute ssh test-vws
then setup a password for your account:
sudo passwd `whoami`
After that, you will need to install a client that will allow you to navigate the GUI for your server.
again, on your server command line execute:
sudo yum -y update
sudo yum -y groupinstall 'Server with GUI'
once finished, follow this guige to install and setup Teradici Cloud Access Software (Remote Desktop Agent for CentOS).
Installing Teradici Cloud Access Software
On your virtual workstation, install the Teradici repositories:
sudo yum -y install https://downloads.teradici.com/rhel/teradici-repo-latest.noarch.rpm
Install Teradici Standard Agent for Linux:
sudo yum -y update
sudo yum -y install pcoip-agent-standard
Then you will have to register the Agent and create a firewall rule to allow the connection, just follow the guide, and your desktop connection will look like this:
I installed elasticsearch this way :
retrieved the tar.gz on windows, extracted it and put it on a zip
uploaded the zip over ssh on a server and use 'unzip file' to unzip it.
I modified the elasticsearch file so that it has this line
export JAVA_HOME = "/home/xxx/project1/jdk1.8.0_73_linux64"
just below
#!/bin/sh
now when I go into /home/xxx/project1/elasticsearch/bin and type
./elasticsearch
I get
-bash: ./elasticsearch: Permission denied
What could I do to get more information about the problem?
I'm logged as user xxx
Thanks.
The problem is, that you've installed elastic being logged in as root. Now you're surely logged in as not root. If you're working as a user with root privileges, you potentially could start elastic, but it tells you, you can't run in as root. The owner of your elastic folder is root (he installed it). So, all you need to do is to change the owner of a folder to your xxx-user (to let him run elastic). You can easily do it executing a command:
chown -R new_owner path
for example, user is xxx and path is /opt/elasticsearch-2.3.5:
chown -R xxx /opt/elasticsearch-2.3.5
"-R" parameter ensures, that not only folder, but all files inside will recursively change the owner you provide.
Try to install using the package Yum Install for elasticsearch.
Else try: Its sounds like the user permission to access the files.
Ensure that you have downloaded the linux distribution (Optional) Since you have mentioned its tar.gz.
If you have extracted using sudo command then you need to change the user permission for elasticsearch folder to logged in user OR start the elasticsearch using sudo command
sudo ./elasticsearch -d
Check the execution permission if not please do the same by following command
sudo chmod +x /home/xxx/project1/elasticsearch/bin/elasticsearch.sh
Try this things if not please create a chat window and invite me.
Looking ahead I will immediately say that the ES app doesn't work using the sudo
In my case with ES 6.8.1 version on ubuntu i solved the problem using this steps:
Add the current user(or any other) to ES group:
sudo adduser <yourName> elasticsearch
Add possibility to execute ES:
sudo chmod +x /usr/share/elasticsearch/bin/elasticsearch
Then i changed owner of some paths**, in my case these were:
sudo chown -R <yourName>:elasticsearch /etc/default/elasticsearch
sudo chown -R <yourName>:elasticsearch /etc/elasticsearch
sudo chown -R <yourName>:elasticsearch /var/log/elasticsearch
**I started the application several times and then looked where I had no permission
Then i started ./usr/share/elasticsearch/bin/elasticsearch and saw the long-awaited JSON on port 9200 :)
Hope this will help someone.
I have an Amazon ec2 instance in which I can login through putty. I want GUI on that instance. Please anyone help me, how can I get GUI on ec2 instance.
Install VNC and connect using VNC. View the video here.
You can also use an X11 server like MobaXTerm: http://mobaxterm.mobatek.net/ ot Xming: http://sourceforge.net/projects/xming/ (assuming you work on a PC running Windows).
login ec2 instance and execute below commands
Sudo apt-get update
Sudo apt-get install lxde
sudo start lxdm
sudo apt-get install xrdp
sudo passwd ubuntu
then open RDC
username -- hostname which you provided in putty
