要在遠(yuǎn)程對Linux服務(wù)器桌面進(jìn)行控制,一般都要用到Xmanager,但是要使用這個(gè)東東是要經(jīng)過一定的配置才可以的,下面針對RedHat AS4|AS5兩個(gè)不同的環(huán)境,對系統(tǒng)的配置來說明一下使用遠(yuǎn)程桌面控制的過程:
一、系統(tǒng)配置
1、修改/etc/X11/xdm/Xaccess文件
找到其中的
# * #any host can get a login window
這句代碼中,去掉前面的#使其生效。
該文件是X窗口的配置文件,目的是允許所有用戶登錄
注:AS5中的對應(yīng)文件是/usr/share/config/kdm/Xaccess,且經(jīng)驗(yàn)證并不一定需要修改
2、修改etc/X11/gdm/gdm.conf文件
找到
# XDMCP is the protocol that allows remote login. If you want to log into
# gdm remotely (I'd never turn this on on open network, use ssh for such
# remote usage that). You can then run X with -query <thishost> to log in,
# or -indirect <thishost> to run a chooser. Look for the 'Terminal' server
# type at the bottom of this config file.
# gdm remotely (I'd never turn this on on open network, use ssh for such
# remote usage that). You can then run X with -query <thishost> to log in,
# or -indirect <thishost> to run a chooser. Look for the 'Terminal' server
# type at the bottom of this config file.
[xdmcp]
# Distributions: Ship with this off. It is never a safe thing to leave
# out on the net. Setting up /etc/hosts.allow and /etc/hosts.deny to only
# allow local access is another alternative but not the safest.
# Firewalling port 177 is the safest if you wish to have xdmcp on.# Read the manual for more notes on the security of XDMCP.
Enable=false
# Distributions: Ship with this off. It is never a safe thing to leave
# out on the net. Setting up /etc/hosts.allow and /etc/hosts.deny to only
# allow local access is another alternative but not the safest.
# Firewalling port 177 is the safest if you wish to have xdmcp on.# Read the manual for more notes on the security of XDMCP.
Enable=false
這一段,將其中的false修改為true或1
xdmcp的功能上面的這段話中已經(jīng)講的很清楚了,基本上就是Linux的圖形界面的一個(gè)監(jiān)聽端口,端口號為177
所以同時(shí)在該文件中,需要確保177端口打開,即如下代碼:
# The port. 177 is the standard port so better keep it that way
#Port=177
去掉前面的#使該句生效
# The port. 177 is the standard port so better keep it that way
#Port=177
去掉前面的#使該句生效
注:AS5中對應(yīng)文件是/etc/gdm/custom.conf,這個(gè)必須要修改。
3、修改/etc/inittab文件
找到以下代碼段:
# Default runlevel. The runlevels used by RHS are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:
若低于5時(shí),需要設(shè)置該級別為5
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:
若低于5時(shí),需要設(shè)置該級別為5
再找到以下代碼段:
# Run xdm in runlevel 5
x:5:respawn:/etc/X11/prefdm -nodaemon
h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1 </dev/null
將中間那句修改為:
x:5:respawn:/etc/X11/prefdm -nodaemon
h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1 </dev/null
將中間那句修改為:
x:5:respawn:/usr/bin/gdm
注:這個(gè)文件在AS4和AS5中都是一樣的,但是后面的部分不知道是什么意思,可以不改。
4、修改/etc/X11/xdm/xdm-config文件
找到最后一行,在前面加上一個(gè)!
! SECURITY: do not listen for XDMCP or Chooser requests
! Comment out this line if you want to manage X terminals with xdm
!DisplayManager.requestPort: 0
! Comment out this line if you want to manage X terminals with xdm
!DisplayManager.requestPort: 0
注:不知道什么意思,也沒有找到在AS5里對應(yīng)的文件……
5、在/etc/hosts文件中添加機(jī)器名解析
如果是域中的機(jī)器,為了方便起見,可以在/etc/hosts文件中加入IP和機(jī)器名,以便直接登錄
10.11.6.220 XXXXXX
10.11.6.91 YYYYYY
10.11.6.91 YYYYYY
-------------------------------------------------------------------------------------
二、Xmanager的使用
1、打開Xmanager文件夾中的Xbrowser,選擇New新建
2、選擇XDMCP類型,然后Next
3、Method不管,Host填目標(biāo)服務(wù)器IP,Port是177,Next
4、一路Next,最后勾選 Execute the session when this new session wizard,然后Finish
