systemctl stop firewalld.service
systemctl disable firewalld.service
vi /etc/selinux/config
set "SELINUX=disabled" and comment the rest lines.
4.添加用户
[root@cos8 yum.repos.d]# vi /etc/tigervnc/vncserver.users # TigerVNC User assignment # # This file assigns users to specific VNC display numbers. # The syntax is <display>=<username>. E.g.: # # :2=andrew # :3=lisa :1=oracle
5.修改
[root@19c ~]# more /etc/tigervnc/vncserver-config-defaults ## Default settings for VNC servers started by the vncserver service # # Any settings given here will override the builtin defaults, but can # also be overriden by ~/.vnc/config and vncserver-config-mandatory. # # See HOWTO.md and the following manpages for more details: # vncsession(8) Xvnc(1) # # Several common settings are shown below. Uncomment and modify to your # liking. # session=gnome # securitytypes=vncauth,tlsvnc # geometry=2000x1200 # localhost # alwaysshared session=gnome

8.启动服务
发现启动失败，需要重启服务后再次启动才能成功.
[root@cos8 yum.repos.d]#systemctl start vncserver@:1
[root@cos8 yum.repos.d]#systemctl status vncserver@:1
9.查看端口是否启动
[root@19c ~]# ss -nlp|grep 5901 tcp LISTEN 0 5 0.0.0.0:5901 0.0.0.0:* users:(("Xvnc",pid=2200,fd=6)) tcp LISTEN 0 5 [::]:5901 [::]:* users:(("Xvnc",pid=2200,fd=7))
