RStudio installation on Hortonworks Sandbox

mrizvi — Wed, 02 Nov 2016 03:49:08 GMT

I am trying to install R-studio on Hortonworks sandbox 2.5, downloaded this rpm:

rstudio-server-rhel-0.99.893-x86_64.rpm

After installing this package, when I am running rstudio-server verify-installation, it shows me the following message:

initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

I have tried starting, stopping rstudio server, it shows the same message. Has anyone experienced this before? Please help.

PS: Since it is a docker container, 8787 port is not opened so I have configured /etc/rstudio/rserver.conf to use port 8090.

It is working now, please follow the below steps:

wget https://download2.rstudio.org/rstudio-server-rhel-0.99.893-x86_64.rpm
sudo yum install --nogpgcheck rstudio-server-rhel-0.99.893-x86_64.rpm
ln -s /usr/lib64/libssl.so.10 /usr/lib64/libssl.so.6
ln -s /usr/lib64/libcrypto.so.10 /usr/lib64/libcrypto.so.6
yum install dpkg
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl
yum install R
rstudio-server verify-installation

Please change the default port from 8787 to 8090 as this port is not opened in the docker sandbox

Go to file /etc/rstudio/rserver.conf and add this entry : www-port = 8090

Restart the server by typing exec /usr/lib/rstudio-server/bin/rserver. It will take you out from the docker shell but you can relogin. Go to browser anyway and access RStudio by typing 127.0.0.1:8090. The login page will appear, use user credentials maria_dev/maria_dev

@WeiHsiang Tseng, Firstly, try with 8090, not 9080. When you say close, what you are referring to? Have you logout from the shell or power off the image from VirtualBox. In the latter case, if your Sandbox is not up and running, you will not be able to access 8090 port
