以32313133353236313431303231363533e59b9ee7ad9431333365633863root用戶運行以下命令來安裝vncserver;

yum install tigervnc-server

同樣運行以下命令來安裝vncviewer;

yum install vnc

停止并禁用防火墻；

systemctl stop firewalld.service

systemctl?disable firewalld.service

二.配置

vncviewer基本上不用配置；

vncserver的配置，創(chuàng)建一個新的配置文件，以開啟1號窗口為例(也可以同時開啟多個窗口，修改數(shù)字即可)，方法如下：

cp?/lib/systemd/system/vncserver@.service?/lib/systemd/system/vncserver@:1.service

或者再增加一個窗口：

cp?/lib/systemd/system/vncserver@.service?/lib/systemd/system/vncserver@:2.service

編輯/lib/systemd/system/vncserver@:1.service,設(shè)置用戶root相關(guān)參數(shù),最終內(nèi)容如下：

[Unit]Description=Remote?desktop?service?(VNC)After=syslog.target?network.target[Service]Type=forking#?Clean?any?existing?files?in?/tmp/.X11-unix?environmentExecStartPre=/bin/sh?-c?'/usr/bin/vncserver?-kill?%i?>?/dev/null?2>&1?||?:'ExecStart=/sbin/runuser?-l?root?-c?"/usr/bin/vncserver?%i"PIDFile=/root/.vnc/%H%i.pidExecStop=/bin/sh?-c?'/usr/bin/vncserver?-kill?%i?>?/dev/null?2>&1?||?:'

1.設(shè)置為非root用戶報錯：[root@localhost system]# systemctl status -l vncserver@:2.service

3.vnc viewer客戶端連接黑屏

改變xstartup的權(quán)限

這個問題是很多人容易忽視的問題，也是造成連接成功后黑屏的原因之一。

在CentOS中，xstartup的文件路徑為：/root/.vnc/ (可以通過locate xstartup來查看xstartup的文件路徑)

所以需要執(zhí)行：chmod 777 /root/.vnc/xstartup

關(guān)閉防火墻

systemctl stop firewalld.service #停止

systemctl disable firewalld.service #禁用

三.應(yīng)用

更新systemctl以使其生效；

systemctl daemon-reload

設(shè)置vncserver的密碼；

vncpasswd root

按提示輸入密碼以及確認密碼

啟動該服務(wù)用來啟用vnc的1號窗口；

systemctl?start?vncserver@:1.service??或者?vncserver?:1

關(guān)閉1號窗口：

systemctl?stop?vncserver@:1.service???或者?vncserver?-kill?:1

設(shè)置為開機自動啟動；

systemctl?enable?vncserver@:1.service
