Redhat/Oracle/Rocky Linux 部署vnc server

        Linux大部分是通过SSH远程命令行界面进行管理，有时候需要通过远程桌面环境部署、运行一些图形化应用程序,可以通过VNC方式进行。这里以Rocky Linux 8  部署VNC Server 为例，其他Linux 放行版本类似:

       1、配置好本地ISO yum 源：

           挂载iso 安装镜像至/media 目录

          mount /dev/sr0 /media

   

  于/etc//etc/yum.repos.d/  目录新增 local_Rocky_Linux.repo 文件，内容如下:

[media-baseos]
baseurl=file:///media/BaseOS
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
  priority=1
[media-appstream]
  name=Rocky Linux $releasever - Media - AppStream
  baseurl=file:///media/AppStream
gpgcheck=1
enabled=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
  priority=1

：

2、安装vnc server 软件包：

#yum install tigervnc-server

Complete!

3、启动vnc server 服务，设置 vnc 连接密码：

su – root

# vncserver

WARNING: vncserver has been replaced by a systemd unit and is now considered deprecated and removed in upstream.
Please read /usr/share/doc/tigervnc/HOWTO.md for more information.

You will require a password to access your desktops.

Password:
Verify:
Would you like to enter a view-only password (y/n)? n
A view-only password is not used

New 'yw-zabbix:1 (root)' desktop is yw-dba-testdb:1

Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/yw-dba-testdb:1.log

su – oracle

# vncserver

WARNING: vncserver has been replaced by a systemd unit and is now considered deprecated and removed in upstream.
Please read /usr/share/doc/tigervnc/HOWTO.md for more information.

You will require a password to access your desktops.

Password:
Verify:

New 'yw-zabbix:1 (oracle)' desktop is yw-dba-testdb:1

Creating default startup script /root/.vnc/xstartup
Creating default config /oracle/.vnc/config
Starting applications specified in /oracle/.vnc/xstartup
Log file is /oracle/.vnc/yw-dba-testdb:1.log

如果后面需要修改vnc 连接密码可以通过vncpasswd 命令进行修改

4、设置vnc server 开机启动：

#systemctl enable vncserver@:1.service  --第一个桌面环境
Created symlink /etc/systemd/system/multi-user.target.wants/vncserver@:1.service → /usr/lib/systemd/system/vncserver@.service.

启动第二个桌面环境

# systemctl enable vncserver@:2.service –第二个桌面环境
Created symlink /etc/systemd/system/multi-user.target.wants/vncserver@:2.service → /usr/lib/systemd/system/vncserver@.service.

编辑文件/etc/tigervnc/vncserver.users

增加会话窗口与用户映射关系，第一个桌面环境与root 账号关联，第二个桌面环境与oracle账号关联：

# TigerVNC User assignment
#
# This file assigns users to specific VNC display numbers.
# The syntax is <display>=<username>. E.g.:
#
# :2=andrew
# :3=lisa
:1=root
:2=oracle

5、vnc 客户端，可至网站 https://www.tightvnc.com/ 下载 tightvnc 客户端

      vnc server 输入 ip:1 即可连接
