RHEL7.5 上執行的服務未在 RHEL8 上執行（httpd 服務）

我的服務在 RHEL 7.5 上運作良好，現在我已升級到 RHEL 8，但相同的服務失敗，狀況如下：

Service.service - LSB: Web Server
Loaded: loaded (/etc/rc.d/init.d/Service; generated)
Active: failed (Result: protocol) since Mon 2020-04-06 12:02:21 IST; 38min ago
Docs: man:systemd-sysv-generator(8)
Process: 403 ExecStart=/etc/rc.d/init.d/Service start (code=exited, status=0/SUCCESS)

Apr 06 12:02:21 localhost.localdomain systemd[1]: Starting LSB: Web Server...
Apr 06 12:02:21 localhost.localdomain Service[403]: httpd (pid 29434) already running
Apr 06 12:02:21 localhost.localdomain systemd[1]: Service.service: Refusing to accept PID outside of service control group, acquired through unsafe symlink chain:
/usr/local/apache/logs/Service.pid
Apr 06 12:02:21 localhost.localdomain systemd[1]: Service.service: Refusing to accept PID outside of service control group, acquired through unsafe symlink chain:
/usr/local/apache/logs/Service.pid
Apr 06 12:02:21 localhost.localdomain systemd[1]: Service.service: Failed with result 'protocol'.
Apr 06 12:02:21 localhost.localdomain systemd[1]: Failed to start LSB: Web Server

這是我的服務單元，放置在 /etc/init.d/Service 下，對於 RHEL 7.5 也是如此，但該服務正在運行，而在 RHEL 8 中則不然。這裡要注意的另一件事是網頁伺服器正在按預期工作，儘管給了我這個錯誤。

請幫我解決這個問題。

如果您在日記條目中看到：

Refusing to accept PID outside of service control group, acquired through unsafe symlink chain:

7.5 中的 systemd 版本沒有額外的檢查來檢查服務的 pid 是否在 systemd 單元的 cgroup 之外。

如果要將 7.5 系統更新到 7.7 或更高版本，也會失敗並出現相同的錯誤。

如果您將 sysv init 腳本轉換為真正的 systemd 服務單元，您可能會有更好的運氣。
