centos8下安装xampp保错Cannot load modules/mod_perl.so into server解决方案

centos8 下安装xampp保错Cannot load modules/mod_perl.so into server解决方案：
命令行输入：
sudo dnf install libnsl

httpd: Syntax error on line 522 of /opt/lampp/etc/httpd.conf: Syntax error on line 13 of /opt/lampp/etc/extra/httpd-xampp.conf: Cannot load modules/mod_perl.so into server: libnsl.so.1: cannot open shared object file: No such file or directory

ps:使服务器可以被外部地址访问，修改Xampp的两个配置文件

# vim etc/httpd.conf
<Directory />
    AllowOverride All
    Order allow,deny
    Allow from all
    #Require all denied
</Directory>

# vim etc/extra/httpd-xampp.conf
# since XAMPP 1.4.3
<Directory "/opt/lampp/phpmyadmin">
    AllowOverride AuthConfig
    #AllowOverride AuthConfig Limit
    Require all granted
    #Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
