在 AWS Linux AMI 上安裝 OTRS 導致 500 內部伺服器錯誤頁面

我正在 Amazon Linux AMI 2017.03.0 (HVM) 上創建一個新的 OTRS 實例，但無法執行 installer.pl。我的安裝步驟如下（到目前為止我已經完成了大約四次）：

• 設置主機名
• 使用伺服器的 FQDN (172.10.10.10 otrs.example.com) 將私有 IP 地址添加到 hosts 文件
• sudo yum -y update
• sudo yum -y install bash-completion --enablerepo=epel
• wget http://ftp.otrs.org/pub/otrs/RPMS/rhel/ ... noarch.rpm
• sudo yum -y install --nogpgcheck otrs-5.0.18-01.noarch.rpm
• sudo yum install -y mod24_perl "perl(JSON::XS)" "perl(GD::Text)" "perl(Encode::HanExtra)" "perl(GD::Graph)" "perl(Mail::IMAPClient)" "perl(PDF::API2)" "perl(Text::CSV_XS)" "perl(YAML::XS)" "perl(DBD::mysql)"
• sudo /sbin/chkconfig httpd on
• sudo reboot

SELinux 被禁用。重新啟動後，我可以訪問 Amazon Linux AMI 測試頁面，但不能訪問 otrs.example.com/otrs/installer.pl（導致 500 內部伺服器錯誤）。

我的 httpd_error 日誌顯示：

我沒有弄清楚到底出了什麼問題，但它涉及到指定mod24_perl. 此安裝適用於 Amazon Linux：

• sudo yum -y install --nogpgcheck otrs-5.0.18-01.noarch.rpm
• sudo yum install -y "perl(Crypt::Eksblowfish::Bcrypt)" "perl(JSON::XS)" "perl(GD::Text)" "perl(Encode::HanExtra)" "perl(GD::Graph)" "perl(Mail::IMAPClient)" "perl(PDF::API2)" "perl(Text::CSV_XS)" "perl(YAML::XS)" "perl(DBD::mysql)"

我以為我一開始就嘗試過這樣的安裝，但當時肯定配置錯誤。
