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
Password:
Verify:
Would you like to enter a view-only password (y/n)? n

[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

修改信息

/etc/systemd/system/vncserver@:2.service

[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
WorkingDirectory=/home/glj

PIDFile=/home/glj/.vnc/%H%i.pid

ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
#ExecStart=/usr/bin/vncserver -autokill %i

ExecStop=/usr/bin/vncserver -kill %i

Restart=on-success

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
