银河麒麟v10服务器系统配置vnc及一些坑
关闭selinux
setenforce 0
#修改/etc/selinux/config文件，因为文件好几个SELINUX=disabled给注释了暂时手动修改/etc/selinux/config文件
vim /etc/selinux/config
#SELINUX=disabled
# setenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
安装依赖
安装vnc安装包： yum install tigervnc-server tigervnc-server-module
复制 vnc 启动脚本
复制 vnc 启动脚本并更改名称。如vncserver@:1.service 中的 :1 表示“桌面号” 对应启动的网络端口号就是 5900+桌面号 ，即 5901 。
如果再有一个就是 2 ，端口号就是 5902 ，以此类推：
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
以 root 用户访问 VNC 为例，编辑/etc/systemd/system/vncserver@:1.service文件：
[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target
[Service]
Type=forking
#WorkingDirectory=/home/<USER>
#User=<USER>
#Group=<USER>
PIDFile=/root/.vnc/%H%i.pid
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill :1 > /dev/null 2>&1 || :'
ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver :1"
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill :1 > /dev/null 2>&1 || :'
Restart=on-success
RestartSec=15
[Install]
WantedBy=multi-user.target
设置 VNC 密码
执行vncpasswd
vncpasswd
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
重新加载系统配置文件
重新加载系统配置文件（系统新增或配置文件发生变化时，都需要执行 daemon-reload 子命令）
systemctl daemon-reload
设置开机启动并启动服务
systemctl enable vncserver@:1.service
systemctl start vncserver@:1.service
# 关闭：vncserver -kill :1
防火墙配置相应规则
如关闭防火墙可忽略
firewall-cmd --add-port=5901/tcp --permanent
firewall-cmd --reload

处理问题
安装缺失的组件
yum install mate-session-manager mate-desktop
重启服务
systemctl restart vncserver@\:1.service
vnc界面乱码问题
安装缺失的组件
yum install cjkuni-ukai-fonts
yum install *google-noto-fonts*
#yum install google-noto-sans
最终效果
验证后最终效果
另设置普通账号vnc
切换账号设置vnc密码
su - glj
[glj@k8s-188 ~]$ vncpasswd

[glj@k8s-188 ~]$ exit
注销
[root@k8s-188 yum.repos.d]#
创建普通账号 vnc配置文件
cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:2.service

刷新systemctl信息并启动
systemctl daemon-reload
systemctl start vncserver@:2.service
查看启动状态是否正常，或者错误信息
systemctl status vncserver@:2.service
