由于未知的语法错误，无法重新启动 httpd

我无法重新启动 httpd：

[root@controller conf.d]# systemctl restart httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

我看到了日志：

[root@controller conf.d]# systemctl status httpd 
● httpd.service - The Apache HTTP Server

你看到这两行：

7 月 13 日 00:01:48 控制器 httpd[18074]:AH00526: /etc/httpd/conf.d/00-nova-placement-api.conf 第 23 行语法错误:

但在/etc/httpd/conf.d/00-nova-placement-api.conf文件中：

23行是正确的，为什么这里有错误？

答案1

最后我发现错误出现在24行而不是23行。

所以这是系统错误：

24   WSGIProgressGroup nova-placement-api

应该：

24   WSGIProcessGroup nova-placement-api
