Centos 尝试执行 hello.cgi 脚本失败

我正在尝试在 html 目录中执行一个简单的 hello world cgi 脚本，但它失败了。

错误日志：

httpd 配置：

# Further relax access to the default document root:
<Directory "/var/www/html">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options -Indexes +FollowSymLinks +ExecCGI
    AddHandler cgi-script .cgi .pl

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride None

    #
    # Controls who can get stuff from this server.
    #
    Require all granted
</Directory>

你好.cgi 文件：

#!/usr/bin/perl
print "Content-type: text/html\n\n"; # This is mandatory.
print "<h2>Hello world!</h2>";
