vnc怎么删除端口,vnc怎么删除端口的3个命令
大家在使用vnc的时候，经常会使用到vnc端口修改，用户添加删除，批量启动的操作，，本文主要介绍的就是在Linux系统中如何进行vnc端口修改，用户添加删除，批量启动的操作的教程。
如果觉得太麻烦的话可以使用IIS7服务器管理工具，可以批量连接并管理VNC服务器 作为服务器集成管理器，它最优秀的功能就是批量管理windows与linux系统服务器、vps。能极大的提高站长及服务器运维人员工作效率。同时iis7服务器管理工具还是vnc客户端，服务器真正实现了一站式管理，可谓是非常方便。
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"
