vncserver启动报错root A VNC server is already running as :1

[root@42 ~]# service vncserver start
Starting VNC server: 1:root A VNC server is already running as :1

1：使用lsof命令查看5901端口
[root@42 sysconfig]# lsof -i tcp:5901
COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
Xvnc    4711 root    5u  IPv4 171906      0t0  TCP *:5901 (LISTEN)

2：查看当前用户后kill
[root@42 sysconfig]# vncserver -list
[root@42 sysconfig]# vncserver -kill :1
[root@42 ~]# service vncserver start

3：用户配置
配置/etc/sysconfig/vncservers文件
可修改vncserver用户和端口

#VNCSERVERS="1:root 2:test"
VNCSERVERSVNCSERVERARGS[1]="-geometry 1024x768 -alwaysshared"  
VNCSERVERSVNCSERVERARGS[2]="-geometry 1024x768 -alwaysshared"

1：root  5901
2：test  5902
…

不希望root登陆就直接去掉
