Hi
my cluster was running fine ,but after i enable the graphic model in AWS RedHat i am not able to start management service. i got below error .
i checked Selinux and iptables all disabled and the firewall also disabled . Any idea what can cause this issue ?
i think mostly is step 2 but not sure which step.
AWS suggest step to enable graphic model:
1. install graphic model
2. setup XRDP
1. Add the xrdp repository: sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
2. Install xrdp and tiger VNC server: sudo yum install -y xrdp tigervnc-server
3. 3. Setup SELINUX security: chcon --type=bin_t /usr/sbin/xrdp && chcon --type=bin_t /usr/sbin/xrdp-sesman
4. Start and enable the xrdp service: sudo systemctl start xrdp && sudo systemctl enable xrdp
5. Enable RDP port on the instance: sudo firewall-cmd --permanent --add-port=3389/tcp && sudo firewall-cmd --reload (I already disable the firewall so i am able to login CM 7180)
6. Set a password for ec2-user . This password will be used to connect to the RDP session: sudo passwd ec2-user
7. Set password for root as you will be prompted for cloud user password for network proxy and color. Login as root and set the password: sudo su && passwd
