I am confused after seeing Grafana installation steps (pasted below) and want to understand how can I install and run Grapaha as me.
$ echo "deb https://packagecloud.io/grafana/stable/debian/ stretch main" | sudo tee -a /etc/apt/sources.list
$ curl https://packagecloud.io/gpg.key | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install grafana
Can someone explain what the above lines are doing, and how can I get grafana installed for my user.
When I ran
echo "deb https://packagecloud.io/grafana/stable/debian/ stretch main" | sudo tee -a /etc/apt/sources.list
[sudo] password for agrawalo:
Sorry, user agrawalo is not allowed to execute '/usr/bin/tee -a /etc/apt/sources.list' as root.
This is how I did it finally.
wget https://dl.grafana.com/oss/release/grafana-6.2.5.linux-amd64.tar.gz
tar -zxvf grafana-6.2.5.linux-amd64.tar.gz
And then started Grafana by executing
./bin/grafana-server web
To run Grafana open your browser and go to http://localhost:3000/
There you will see the login page. Default username is admin and default password is admin.

I'm interested in running a simple image like this behind a corporate Zscaler firewall:
FROM rocker/r-base
RUN apt-get update && apt-get install libssl-dev
CMD Rscript -e "install.packages('beepr')"
Building the image with docker build -t test . fails with errors like this:
Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown. Could not handshake: Error in the certificate verification. [IP: ]
I've tried some of the solutions from here but they don't work. For example:
FROM rocker/r-base
# Add local certificate to Docker
ADD ./zscaler.cer /usr/local/share/ca-certificates/zscaler.crt
# Move the certificate to the cert dir of openssl and update certificates
RUN CERT_DIR=$(openssl version -d | cut -f2 -d \")/certs ; cp /usr/local/share/ca-certificates/zscaler.crt $CERT_DIR ; update-ca-certificates
# Try making https requests
RUN apt-get update && apt-get install libssl-dev
CMD Rscript -e "install.packages('beepr')"
Same errors persist with docker build -t test .. I've read some possible solutions online but all of them continually fail either for apt-get or for installing packages with R. Is there anyone who has experienced this and found a fix?
Apparently, the current advice is slightly wrong. The certificate should not go in /etc/ssl/certs/ (which is the result of CERT_DIR=$(openssl version -d | cut -f2 -d \")/certs) but rather on CERT_DIR=/usr/local/share/ca-certificates/ (at least on this Ubuntu image). After changing that, update-ca-certificates correctly updates the certificate an all HTTPS requests are successful.
This should work now:
FROM rocker/r-base
# Add local certificate to Docker
ADD ./zscaler.pem /usr/local/share/ca-certificates/ZscalerRootCertificate-2048-SHA256.crt
# update certificates
RUN update-ca-certificates
# Try making https requests
RUN apt-get update && apt-get install libssl-dev
CMD Rscript -e "install.packages('beepr')"
So I've set up an Azure Data Science Virtual Machine on Linux (Ubuntu) and I've executed the following on the terminal to enable Remote R workspace, RStudio Server, R Server Operationalization and hadoop:
sudo apt update
sudo apt -y upgrade

#They say this Data Science Virtual Machine already has RStudio Server, but even though the port 8787 is open, it's nowhere to be found! So installing it now, and after the installation it's accessible by refreshing the page that failed before.

sudo mv StartRemoteRAfterReboot.sh /var/RevoShare/StartRemoteRAfterReboot.sh
sudo /sbin/shutdown -r 5

sudo echo "" >> /etc/rc.local
sudo echo "sh /var/RevoShare/StartRemoteRAfterReboot.sh" >> /etc/rc.local
sudo echo "exit 0" >> /etc/rc.local
exit
I've also tried, one by one, these, to see if it makes any difference to the RStudio Server (it didn't, but even if it did, I want a global solution to work on Remote R Workspace Service and R Server Operationalisation as well, not only RStudio Server):
#Configuring RStudio Server to see the R Server R
sudo echo "rsession-which-r=/opt/microsoft/mlserver/9.2.1/bin/R/R" >> /etc/rstudio/rserver.conf
export RSTUDIO_WHICH_R=/opt/microsoft/mlserver/9.2.1/bin/R/R
sudo echo "RSTUDIO_WHICH_R=/opt/microsoft/mlserver/9.2.1/bin/R/R" >> ~/.profile
source ~/.profile
sudo echo "RSTUDIO_WHICH_R=/opt/microsoft/mlserver/9.2.1/bin/R/R" >> ~/.bashrc
source ~/.bashrc
sudo echo "PATH=$PATH:/opt/microsoft/mlserver/9.2.1/bin/R" >> ~/.bashrc
export PATH=$PATH:/opt/microsoft/mlserver/9.2.1/bin/R
source ~/.bashrc
The problem is that even though "which R" points to R Server's R, i.e. typing "sudo R" will show the message "Loading Microsoft R Server packages, version 9.2.1." and will load packages like RevoScaleR, everything else fails to do so.
Accessing the RStudio Server with http://THE-IP-GOES-HERE.westeurope.cloudapp.azure.com:8787 and logging in with the initial user ("sshuser") (or with any other user for that matter) will NOT load R Server and RevoScaleR rx functions are unavailable
Using my local Visual Studio 2017 to access the remote workspace via "Add connection" on "Workspaces" tab loads MRO and says:
Installed R versions:
[0] Microsoft R Open '3.4.1.1347' (Default)
And finally, when I use R Server's Operationalisation and log in with "mrsdeploy" package's "remoteLogin()" R Server packages like RevoScaleR are not loaded again, so things like "rxSummary(~., data=iris)" fail with error 'could not find function "rxSummary"'
The exact same thing happened when I deployed from azure a "Machine Learning Server 9.2.1 on Linux (Ubuntu)".
I don't want to just use the regular open source R, I want to be able to use the R Server - that's why I deployed this VM. How can I make it so that everything loads R Server's R, not Microsoft R Open? (Like I'm able to do from terminal using "R")
As a result of my having tried all of this and the fact that R Server is loaded in the console, my mind now goes to permissions. Could it be that by default the Data Science VM doesn't have the correct permissions to allow these?
I'm at a loss
RStudio Server is installed on the Ubuntu DSVM, but the service is disabled by default as it does not support SSL. You can enable it with systemctl enable rstudio-server, then start it with systemctl start rstudio-server.
RStudio Server uses the same R as Microsoft R Server, but the .libPaths are different, which is why you cannot load the MRS packages. You will need to manually set the .libPaths so they match.
I wanted to have a Widget to view and edit the time range from within dashboards of kibana. So after lot of research i found a plugin as Kibana-time-plugin. Ref: https://github.com/nreese/kibana-time-plugin
Currently i am using kibana 5.4.0 in my local. After installing the plugin i have tried "bower install" as per the command specified in git page. But getting an error as :-
$ bower install
/usr/bin/env: ‘node’: No such file or directory
And even if Kibana is not running and giving an error as below attached image:-
kibana5.4.0
Can anyone Guide me on this ?
Thanks in Advance !!!!!!!!!!!!!!!
I think the optimization failures may be due to file permissions, the plugin files need to be accessible by the kibana user. Specifically check this instruction:
Installing plugins with linux packages
Here is a complete script that worked for me. I am new to Kibana and Kibana plugins so any feedback appreciated. Two important notes:
1) I am pulling the zip file from S3 so you will need to edit that.
2) Be sure to restart kibana afterwards and check the logs
#!/bin/bash
# install nodejs and npm
sudo curl --silent --location https://rpm.nodesource.com/setup_6.x | sudo bash -
sudo yum install -y nodejs
sudo npm install -g bower
# copy the plugin zip and unzip it and fix the name
cd /usr/share/kibana/plugins
sudo aws s3 cp s3://<YOUR-BUCKET>/kibana-time-plugin-master.zip .
sudo unzip kibana-time-plugin-master.zip
sudo mv kibana-time-plugin-master kibana-time-plugin
# install the plugin
cd /usr/share/kibana/plugins/kibana-time-plugin
sudo sed -i -e 's/5.0.0/5.4.2/' package.json
sudo chown -R kibana:kibana *
sudo mkdir -p /home/kibana
sudo chown -R kibana:kibana /home/kibana
sudo -u kibana bower install
I had installed nginx and lua in my docker image, but I didn't install nginx on my physical CentOS system. I "docker run my image" and start nginx on my physical CentOS system. So the nginx master and worker process are working. I run an example of nginx-systemtap-toolkit. I run:
sudo ./ngx-active-reqs -p 24945
24945 is worker process id. errors as following:
semantic error: while resolving probe point: identifier 'process' at <input>:6:7
source: probe process("/data1/nginx/sbin/nginx").function("ngx_process_events_and_timers"),
^
semantic error: no match
Pass 2: analysis failed. [man error::pass2]
Number of similar error messages suppressed: 1
In fact, "/data1/nginx/sbin/nginx" is the nginx path in docker image, nginx is not installed on my physical system. So whether I must install nginx on my physical system , or is there other method to use nginx's process function? I don't know how to solve the problem.
To install debug symbol which package is not included in the repositories in the form of -dbg package, you need to add a new repository as detailed in the Debugging Guide:
Add the repositories:
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee -a /etc/apt/sources.list.d/ddebs.list
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com $(lsb_release -cs)-security main restricted universe multiverse
deb http://ddebs.ubuntu.com $(lsb_release -cs)-proposed main restricted universe multiverse" | sudo tee -a /etc/apt/sources.list.d/ddebs.list
Add the GPG key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 428D7C01
Update your package list:
sudo apt-get update
Install the debugging symbols package, in this case coreutils-dbgsym:
sudo apt-get install coreutils-dbgsym
In ubuntu 12.04 (server):
sudo apt-get install libpcre3 libpcre3-dev zlib1g-dev
wget http://nginx.org/download/nginx-1.5.6.tar.gz && tar zxvf nginx-1.5.6.tar.gz && cd nginx-1.5.6 && ./configure && make && sudo make install
Then I try:
sudo service nginx start
or
nginx -s reload
and many others that I find in google - all of them doesnt works. (nginx: unrecognized service, no command found, etc)
How to start nginx?
for you guys, who used nginx installation via passenger:
$ wget -O init-deb.sh https://gist.githubusercontent.com/rschmitty/5891885/raw/9b737a42e950581f16ed3074c69f5bcb920f24cb/660-init-deb.sh
$ sudo mv init-deb.sh /etc/init.d/nginx
$ sudo chmod +x /etc/init.d/nginx
$ sudo /usr/sbin/update-rc.d -f nginx defaults
It enables standard service nginx start|stop|restart|reload commands
You can install nginx like you installed those libraries. The only reason to compile it manually is if you want a really new feature or security fix.
sudo apt-get install nginx
It should automatically start nginx. If not you may start it manually.
sudo /etc/init.d/nginx start
