域名預(yù)訂/競(jìng)價(jià)，好“米”不錯(cuò)過(guò)

這篇文章主要介紹了Ubuntu20.04 VNC 安裝與設(shè)置實(shí)現(xiàn)，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

VNC是一個(gè)遠(yuǎn)程桌面協(xié)議。按照本文的說(shuō)明進(jìn)行操作可以實(shí)現(xiàn)用VNC對(duì)Ubuntu 20.04進(jìn)行遠(yuǎn)程控制。一般的VNC安裝方式在主機(jī)沒(méi)有插顯示器的時(shí)候是無(wú)法使用的。下面的操作可以在主機(jī)有顯示器和沒(méi)有顯示器時(shí)都能夠正常工作。

首先安裝x11vnc

sudo apt-get install x11vnc -y

設(shè)置vnc密碼

sudo x11vnc -storepasswd /etc/x11vnc.pass 

創(chuàng)建x11vnc自啟動(dòng)服務(wù)

創(chuàng)建 /etc/systemd/system/x11vnc.service，并寫入以下內(nèi)容

[Unit]
Description=Start x11vnc at startup.
After=multi-user.target
[Service]
Type=simple
ExecStart=/usr/bin/x11vnc -auth /run/user/1000/gdm/Xauthority -forever -loop -noxdamage -repeat -rfbauth /etc/x11vnc.pass -rfbport 5900 -shared
[Install]
WantedBy=multi-user.target

啟動(dòng)x11vnc服務(wù)

sudo systemctl enable x11vnc
sudo service x11vnc start

此時(shí)如果遠(yuǎn)程的主機(jī)上接了顯示器，那么就可以在局域網(wǎng)通過(guò)VNC進(jìn)行訪問(wèn)了。

為了能夠保證遠(yuǎn)程主機(jī)無(wú)論是否有顯示器，我們都能通過(guò)VNC進(jìn)行遠(yuǎn)程訪問(wèn)，我們還要做下面的修改

創(chuàng)建默認(rèn)的xorg.conf文件

sudo Xorg :1 -configure

此時(shí)程序會(huì)生成 /root/xorg.conf.new文件

我的默認(rèn)文件內(nèi)容如下

將此文件復(fù)制至 /usr/share/X11/xorg.conf.d/xorg.conf

這個(gè)文件保證在主機(jī)上插有顯示器的時(shí)候，系統(tǒng)界面能在顯示器上正常顯示。下面我們?cè)俳o系統(tǒng)添加一個(gè)虛擬顯示器，當(dāng)主機(jī)沒(méi)有顯示器的時(shí)候系統(tǒng)就使用這個(gè)虛擬顯示器。

安裝虛擬顯卡驅(qū)動(dòng)

sudo apt install xserver-xorg-video-dummy

在這個(gè)文件的最后添加下面的內(nèi)容

Section "Monitor"
Identifier "Monitor1"
HorizSync 1.0 - 2000.0
VertRefresh 1.0 - 200.0
# Add 16:9 modes, others are automatically detected.
Modeline "1280x720" 74.48 1280 1336 1472 1664 720 721 724 746
Modeline "1920x1080" 172.80 1920 2040 2248 2576 1080 1081 1084 1118
EndSection

Section "Device"
Identifier "Card1"
Driver "dummy"
VideoRam 256000
EndSection

Section "Screen"
DefaultDepth 24
Identifier "Screen1"
Device "Card1"
Monitor "Monitor1"
SubSection "Display"
Depth 24
Modes "1920x1080"
EndSubSection
EndSection

這樣我們就創(chuàng)建了一個(gè)使用虛擬顯卡的虛擬顯示器。為了讓虛擬的顯示器和真實(shí)顯示器都能工作，我們需要把最上面的ServerLayout 進(jìn)行更改

Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" 0 0
EndSection

現(xiàn)在重新啟動(dòng)遠(yuǎn)程電腦，就可以在沒(méi)有顯示器的情況下遠(yuǎn)程了。

以上的方法還有一個(gè)問(wèn)題。就是在用戶沒(méi)有登錄的其情況下是沒(méi)辦法遠(yuǎn)程的。所以需要把用戶設(shè)置成自動(dòng)登錄。
