这篇文章主要介绍 vnc 如何删除端口，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

IIS7 服务器管理工具界面如下：

yum -y install tiger-server

!/usr/bin/env bash

config_file=”/etc/sysconfig/vncservers”
port_file=”/root/.vnc_port”
vncserver_file=which vncserver

sed -i ‘s/5900\ +/12000\ +/g’$vncserver_filesed -i ‘s/12000\ +/5900\ +/g’$vncserver_file 端口修改成起始端口

function port_init {
last_port=5900
if [[-e $port_file]];then
old_port=cat $port_file
sed -i “s/$old_port\ +/5900\ +/g”$vncserver_file
echo“5900”$port_file
fi

}

修改端口

function modfy_port {
last_port=$1
if [[$last_port ==“”]];then
echo“Please input the port you want“
else
if [[-e $port_file]];then
old_port=cat $port_file
sed -i “s/$old_port\ +/$last_port\ +/g”$vncserver_file
echo $last_port $port_file
else
sed -i “s/5900\ +/$last_port\ +/g”$vncserver_file
echo $last_port $port_file
fi
fi
}

添加用户

function adduser {
if [[$1 ==“”]];then
echo“Please input a user name”
else
user_num=grep -w VNCSERVERS $config_file|awk {print $NF} |cut -d : -f1
latest_user_num=expr $user_num + 1
last_user=grep -w VNCSERVERS $config_file|awk {print $NF} |awk -F {print $1}
sed -i“s/$last_user/$last_user\ $latest_user_num:$1/“$config_file
echo“VNCSERVERSVNCSERVERARGS[$latest_user_num]=\”-geometry 1600×900 -alwaysshared\””$config_file
useradd $1
echo“**“|passwd —stdin $1
fi
}

删除用户

function deleteuser {
if [[$1 ==“”]];then
echo“Please input the username to delete”
else
delete_user_match=$(egrep -w“[0-9]{1,3}:$1”$config_file|wc -l)
if [[$delete_user_match -ne 1]];then
echo“Please make sure the user name is correct”
else
delete_user_num=egrep -w [0-9]{1,3}:$1 $config_file|awk -F :$1 {print $1} |awk {print $NF}
sed -i“s/\ $delete_user_num:$1//“$config_file
sed -i“s/.[$delete_user_num].//“$config_file
userdel -r $1
fi
fi
}

服务启动

function start {

#user_list=`grep -w VNCSERVERS $config_file|awk -F   {print $2} |sed  s/[0-9]\+://g  `
user_list=`grep -w VNCSERVERS $config_file|awk -F   {print $2} `

 expect -c   
 set timeout 1200;
 spawn /usr/bin/su - $user -c  vncserver\ \:$user_port 
 expect {  Password:  {send  *** \r;exp_continue}
  Verify:  {send  *** \r;}
 }
 expect eof; 
done

}
function stop {
user_list=ps aux |grep vnc |grep rfbport |awk {print $1 $12}
for i in $user_list
do
user_port=$(echo $i|cut -d”:”-f2)
user=$(echo $i|cut -d”:”-f1)
su – $user -c“vncserver -kill :$user_port”
done
