Eu segui as duas instruções aqui e aqui . Eu cheguei muito longe, mas a última tarefa nesses guias é executar systemctl start vncserver@:10.service e lá eu recebo um erro.
Quando executo esse comando, (onde 10 é o que eu conheço como o deslocamento da porta), recebo o seguinte erro:
Job for vncserver@:10.service failed. See "systemctl status vncserver@:10.service" and "journalctl -xe" for details.
Eu executei o comando como um usuário com sudo e como root . Ambas as vezes recebo o mesmo erro.
Para resumir, os guias dizem para:
yum install tigervnc-server cp/lib/systemd/system/[email protected]/etc/systemd/system/[email protected]
Edite esse arquivo para substituir a variável user
reiniciar ( ~]# systemctl daemon-reload )
defina vncpasswd
Executar: systemctl enable vncserver@:display_number.service
Executar: systemctl start vncserver@:display_number.service
Esta é a saída de systemctrl status vncserver@:10.service

Eu acho que display_number é o "deslocamento de porta" (quantas portas adicionar a 5900), mas este é o erro que estou recebendo. Gostaria de receber ajuda, obrigado.
A linha mais relevante do seu registro é:
Apr 10 04:47:33 democom runuser[23853]: -bash: /usr/bin/vncserver: /usr/bin/perl: bad interpreter: Permission denied
É possível que o perl não esteja instalado em / usr / bin? Caso contrário, algo parece estar errado logo no início da execução desse script perl. Uma maneira de depurar seria pegar qualquer comando que esteja sendo executado no arquivo de unidade do systemd e executá-lo manualmente, para ver qual é o erro.
Verifique no diretório /tmp/.X11-unix se X? arquivo já existe (? o display #). Se sim, rm -f esse arquivo e reinicie o vncserver. Se não, alguma outra coisa está bloqueando o caminho?
