由於編碼失敗，FreeIPA 伺服器安裝失敗

我正在嘗試在 CentOS 7 節點上安裝 FreeIPA 伺服器。從一個乾淨的圖像開始，我正在執行以下程式碼（不包括一些不相關的部分）：

       echo 'LANG=en_US.utf-8' >> /etc/environment
       echo 'LC_ALL=en_US.utf-8' >> /etc/environment

       yum -y install epel-release npm wget net-tools patch sbt python36u python36u-devel krb5-devel
       yum -y install python36u-pip

       yum install -y ipa-server

       systemctl start named
       systemctl enable named

       ln -s /bin/pip3.6 /bin/pip
       pip install --upgrade pip
       pip install kdcproxy ipaplatform gssapi ipalib

       ipa-server-install -p directoryManagerAdmin -a kerberosAdmin --ip-address=$ipaddress -n test.hadoop.com -r TEST.HADOOP.COM --mkhomedir -U

ipa-server-install 正常工作，直到它開始嘗試使用 Web API 的部分。此時，由於內部伺服器錯誤，它失敗了。查看 /var/log/httpd/error_log 的日誌，我發現以下錯誤重複了多次。

[Thu Jul 25 19:26:30.952879 2019] [wsgi:error] [pid 2934] mod_wsgi (pid=2934): Failed to exec Python script file '/usr/share/ipa/wsgi.py'.

我已經嘗試設置 LC_ALL 和 LANG（如腳本中所示），但它仍然出現。我需要做些什麼來解決這個問題，以便伺服器的 Web API 能夠正常工作？

編輯：根據@abbra @michael-hampton 的建議，我恢復了對 Python 問題的修復。請參閱下文了解我正在執行的新命令集，以及我在 httpd/error_log 中看到的錯誤之一。請注意，我也看到其他包失去，但它們都相似。

       yum -y install epel-release npm wget net-tools patch sbt krb5-devel

       yum install -y ipa-server

       systemctl start named
       systemctl enable named

/var/log/httpd/error_log 中的輸出：

您可能啟用了 IUS 儲存庫。它們提供覆蓋和擴展標準 CentOS 建構的軟體包。結果，它們（在這種特殊情況下）使您的系統與 IPA 伺服器軟體包的要求不兼容。如果您要刪除 python36u-mod_wsgi，則會選擇一個原始的（基於 python2 的）。

我不保證此配置（CentOS + IUS 軟體包）完全適用於 FreeIPA，因為沒有人測試過它。
