vnc如何删除端口

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_file

sed -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 1600x900 -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}'`
echo $user_list
for i in $user_list
do
    user_port=$(echo $i|cut -d":" -f1)
    user=$(echo $i|cut -d":" -f2)
    #su - $user -c "vncserver -kill :$user_port"
    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
}
case $1 in
   adduser)
       adduser $2
   ;;
   deleteuser)
       deleteuser $2
   ;;
   stop)
       stop
   ;;
   start)
       start
   ;;
   default_port)
       port_init
   ;;
   modify_port)
       modfy_port $2
   ;;
   *)
       echo -e “Usage:\ncommands:\n  adduser#define:please input a user name,Don’t use pure numbers\n  deleteuser#define:please input a complete user name\n  start   #define:start all service\n  stop   #define:stop all service\n  default_port   #define:Modify port to default start segment\n  modify_port#define:Modify the port to the segment you want”
