rserver[1692]: ERROR system error 13 (Permission denied)

Hi, Cole and kevinushey,

Thanks for providing suggestions. I disabled the SELinux and rebooted the operating system, now the rstudio-server can be accessed through web browser! Here is the screenshot of success!

Since the SELinux is turned on by default on RedHat/CentOS/Fedora or several derivatives, perhaps you guys can try to make rstudio-server compatible with SELinux, or give a warning in the installation instructions. That would be very helpful for users.

Here is the test process. I refer to the web page here: https://www.tecmint.com/disable-selinux-in-centos-rhel-fedora/ , I tested the hypothesis about SELinux.

[testuser@third-test ~]$ sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   enforcing
Mode from config file:          enforcing
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Memory protection checking:     actual (secure)
Max kernel policy version:      31

I changed the directive SELinux=enforcing to SELinux=disabled

[testuser@third-test ~]$ sudo vi /etc/sysconfig/selinux

Then I reboot my system.

[testuser@third-test ~]$ sudo shutdown -r now

Now the SELinux is disabled.

[testuser@third-test ~]$ sestatus
SELinux status:                 disabled

Then the rstudio-server status looks good.

[testuser@third-test ~]$ sudo rstudio-server status
