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_listfor i in $user_listdo    user_port=$(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"
