CentOS 7.2搭建VNC远程桌面服务的方法
<p><span><strong>一、图形界面安装（MATE DESKTOP）</strong></span></p>
<p>
CentOS 7 系统下，本文以 MATE 桌面环境安装进行安装配置说明：</p>
<p>
登录服务器，执行如下指令安装桌面环境：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_447440">
<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 comments"># 先安装 MATE Desktop</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">yum </code><code class="bash functions">groups</code> <code class="bash functions">install</code> <code class="bash string">"MATE Desktop"</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
命令输入之后，会列出一大堆文字的，然后显示这个y/d/n，输入y，按回车下载安装；</p>
<p>
安装完成，显示下面图片complete</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_863995">
<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 comments">#安装好 MATE Desktop 后，再安装 X Window System。</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">yum </code><code class="bash functions">groups</code> <code class="bash functions">install</code> <code class="bash string">"X Window System"</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
命令输入之后，会列出一大堆文字的，然后显示这个y/d/n，输入y，按回车下载安装；</p>
<p>
安装完成</p>
<p>
设置默认通过桌面环境启动服务器：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_624412">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">systemctl </code><code class="bash functions">set</code><code class="bash plain">-default graphical.target</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
安装完成后，通过 reboot 等指令重启服务器，或者在 ECS 服务器控制台重启服务器，重启后系统将自动进入图形界面</p>
<p>
<span><strong>二、安装vncserver</strong></span></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>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_651442">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">yum -y </code><code class="bash functions">install</code> <code class="bash plain">tigervnc-server tigervnc</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
2、Centos7需要配置的文件/lib/systemd/system/vncserver@.service，复制一份文件，并改名为vncserver@:1.service</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code64901">
<br>
# cp /lib/systemd/system/vncserver@.service/lib/systemd/system/vncserver@:1.service</div>
<p>
</p>
<p>
3、将文件中的<User>用你当前的用户替换</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_212215">
<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>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
<div class="line number5 index4 alt2">
5</div>
<div class="line number6 index5 alt1">
6</div>
<div class="line number7 index6 alt2">
7</div>
<div class="line number8 index7 alt1">
8</div>
<div class="line number9 index8 alt2">
9</div>
<div class="line number10 index9 alt1">
10</div>
<div class="line number11 index10 alt2">
11</div>
<div class="line number12 index11 alt1">
12</div>
<div class="line number13 index12 alt2">
13</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain"></code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">Description=Remote desktop service (VNC)</code>
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">After=syslog.target network.target</code>
</div>
<div class="line number4 index3 alt1">

</div>
<div class="line number7 index6 alt2">
<code class="plain plain"># Clean any existing files in /tmp/.X11-unix environment</code>
</div>
<div class="line number8 index7 alt1">
<code class="plain plain">ExecStartPre=/usr/bin/vncserver -kill %i</code>
</div>
<div class="line number9 index8 alt2">
<code class="plain plain">ExecStart=/usr/bin/vncserver %i -geometry 1280x720 -depth 24</code>
</div>
<div class="line number10 index9 alt1">
<code class="plain plain">PIDFile=/root/.vnc/%H%i.pid</code>
</div>
<div class="line number11 index10 alt2">
<code class="plain plain">ExecStop=/usr/bin/vncserver -kill %i</code>
</div>
<div class="line number12 index11 alt1">
<code class="plain plain"></code>
</div>
<div class="line number13 index12 alt2">
<code class="plain plain">WantedBy=multi-user.target</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
4、更新systemctl</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_228989">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">systemctl daemon-reload</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
5、设置为自动启动</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_503691">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">systemctl enable vncserver@:1.service</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>

</div>
<p>
6、启动vnc服务</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_86559">
<div class="toolbar">

</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
7、修改配置文件（解决vncviewer连接时出现蓝屏或灰屏的问题） </p>
<p>
vim ~/.vnc/xstartup</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_351318">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
8、 重启vnc服务,输入如下两个命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_161166">
<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="plain plain">vncserver -kill :1 </code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">vncserver</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
完成所有配置（防火墙放行590X端口的设置不在此列出），客户端可以使用IP:5901进行远程桌面连接</p>
