Server installation fonts

1. Problem Description

• Linux server export text overlap.

• When exporting pdf, the Chinese characters in the chart become boxes.

• Insert a diagonal scramble with a square diagonal line.

2. Reason Analysis

The server is missing the font used by the dashboard.

3. Solution ideas

The server installs the missing font.

Note: In a clustered environment, missing fonts need to be installed on all nodes.

1. Check Chinese Language Pack

Check whether there is font package zh_cn.UTF-8 in the system, check whether the system default language is zh_cn.UTF-8:

locale -a | grep zh_CN

If not, please refer to the following for the method of installing the Chinese language pack and setting the system default language: Linux system installation Chinese language pack

2. Confirm missing fonts

The fonts used in the garbled parts of the dashboard are missing fonts.

It is assumed that after the grouping table is exported, the header is garbled, and the header is in bold, so the bold font package is missing.

3. Install missing fonts

1）Usefc-listto view the font library, as shown in the following figure:

Note: if prompted: -bash: fc-list: command not found, use yum -y install fontconfig statement to view the font library again.

2) Create a new directory chinese under the /usr/share/fonts directory, and upload the fonts in the local windows system C:\Windows\Fonts to the /usr/share/fonts/chinese directory.

For example, upload the "SimHei" font, as shown in the following figure:

3) Modify the permissions of the chinese folder, as shown in the following figure:

chmod -R 755 /usr/share/fonts/chinese

4) Execute the following command:

cd /usr/share/fonts/chinese
mkfontscale #Font extension
mkfontdir #New font directory
fc-cache -fv #Refresh cache, or execute
fc-cache /usr/share/fonts/chinese/fc-list #View system fonts

To execute mkfontscale, prompt mkfontscale: command not found, install: yum install mkfontscale.

Execute the command: fc-list | grep SimHei.ttf to check whether the installation is successful:

4. Restart the project

After the font is installed, restart the project, and the corresponding font will be displayed during preview and export.

1. Confirm the missing font

The fonts used in the garbled parts of the dashboard are missing fonts.

It is assumed that after the grouping table is exported, the header is garbled, and the header is in bold, so the bold font package is missing.

2. Install missing fonts

After confirming that there is no corresponding font in the C:\Windows\Fonts folder of the server, import the downloaded font into the C:\Windows\Fonts folder, or install it directly in the font settings of the system.

If there is no boldface in the system, directly import fonts in the C:\Windows\Fonts folder. As shown in the following figure:

3. Restart the project

After the font is installed, restart the project, and the corresponding font will be displayed during preview, export and printing.

Note: after the font is installed, if the font cannot be read, you can copy the font to the server JDK_HOME/jre/lib/fonts, restart the container where the project is located.
