我的服务在 RHEL 7.5 上运行良好,现在我已升级到 RHEL 8,但相同的服务失败,状态如下:
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:

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:

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
这是我的服务单元,放置在 /etc/init.d/Service 下,对于 RHEL 7.5 也是如此,但该服务正在运行,而在 RHEL 8 中则不然。这里要注意的另一件事是网络服务器正在按预期工作,尽管给了我这个错误。

请帮助我解决这个问题。

如果您在日记条目中看到:
Refusing to accept PID outside of service control group, acquired through unsafe symlink chain:
7.5 中的 systemd 版本没有额外的检查来检查服务的 pid 是否在 systemd 单元的 cgroup 之外。
如果要将 7.5 系统更新到 7.7 或更高版本,也会失败并出现相同的错误。
如果您将 sysv init 脚本转换为真正的 systemd 服务单元,您可能会有更好的运气。
