Can't run VNC on Centos 7 with GNOME

[nermin_dadan]

Hello,

I am having trouble making VNC work on Centos 7 with GNOME.

These are the steps I follow:
1. sudo yum install tigervnc-server
2. vncpasswd
3. put my password, and verify it.
4. cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
5. It makes new file in that path.
6. Content of that file is:
[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking

# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/usr/sbin/runuser -l futura -c "/usr/bin/vncserver %i"
PIDFile=/home/futura/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'

[Install]
WantedBy=multi-user.target
7. I have put my user "futura" in file.
8. I run systemctl daemon-reload
9. then run systemctl start vncserver@:1
10. error happens: Job for vncserver@:1.service failed because a configured resource limit was exceeded. See "systemctl status vncserver@:1.service" and "journalctl -xe" for details.
11. systemctl status vncserver@:1.service. this is the output: ● vncserver@:1.service - Remote desktop service (VNC)

How can I make this work?

Thank you for your support.

Did you set a password for the user and does the path leading down to /home/futura/.vnc/server1.futuratoneri.info:1.pid exist?

[nermin_dadan]

I have set up password with:
vncpasswd

Also there is path /home/futura/.vnc/
but there is no file server1.futuratoneri.info:1.pid in it.

What could be the issue?

Thank you for your support!
