Centos7远程桌面 vnc/vnc-server的设置详解
<p><strong>Centos7与Centos6.x有了很大的不同。</strong></p>
<p>
为了给一台服务器装上远程桌面，走了不少弯路。写这篇博文，纯粹为了记录，以后如果遇到相同问题，可以追溯。</p>
<p>
1、假定你的系统没有安装vnc的任何软件，那么，首先安装vnc</p>
<p>
<span>yum -y install tigervnc-server tigervnc</span></p>
<p>
2、Centos7之前的系统，如果安装vnc一般都需要配置</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_183550">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain"></code><code class="bash comments"># cat /etc/sysconfig/vncservers </code>
</div>
<div class="line number2 index1 alt1">
<code class="bash comments"># THIS FILE HAS BEEN REPLACED BY /lib/systemd/system/vncserver@.service</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
但是，如上所述，Centos7需要配置的文件在</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_27437">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

<div class="line number2 index1 alt1">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain"></code><code class="bash comments"># ll /lib/systemd/system/vncserver@.service</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">-rw-r--r--. 1 root root 1744 Jun 10 14:15 </code><code class="bash plain">/lib/systemd/system/vncserver</code><code class="bash plain">@.service</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
3、文件内有如下提示</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_815765">
<div class="toolbar">
<span>?</span>
</div>

<td class="code">

</td>

</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">

</div>
</div>
</div>
<p>
4、复制一份文件，并改名为vncserver@:1.service</p>
<p>
<span># cp </span><span>/lib/systemd/system/vncserver@.service</span><span>/lib/systemd/system/vncserver@:1.service</span></p>
<p>
5、将文件中的<User>用你当前的用户替换，将%i替换为1</p>

</div>
<div class="codetool" id="codetool">
<div class="code_n">

</div>
</div>
</div>
<p>
6、更新systemctl</p>
<p>
<span>systemctl daemon-reload</span></p>
<p>
7、设置为自动启动</p>
<p>
<span>systemctl enable vncserver@:1.service</span></p>
<p>
8、启动vnc服务</p>
<p>
<span>systemctl start vncserver@:1.service</span></p>
<p>
9、在iptables中加入对应的端口5901（注意，如果有其他用户，那么也需要将端口加上。vnc的端口默认是5900 + n）</p>

<p>
<span>注意：</span></p>
<p>
1、如果你不配置和启用防火墙，此时用VNC Viewer连接的话，会报："connect：Connection timed out(10060)"错误。</p>
<p>
2、本文是以root用户为例，如果其他用户也需要登录，那么，还需要将文件复制为</p>
<p>
<span>cp </span><span>/lib/systemd/system/vncserver@.service</span><span>/lib/systemd/system/vncserver@:2.service</span></p>
<p>
同时，将文件内的%i改为2，并建立对应用户的vncpasswd。</p>
<p>
3、你可以通过UltraVNC，TigerVNC或者RealVNC Viewer进行访问，我在win7下使用这3中工具均能连接</p>
