过多的Windows安全事件日志 从办公室使用VPC与家庭VPN：不是所有主机都可以访问 使用容器优化的操作系统在k8s虚拟机上安装二进制文件 安装syslog-ng Ubuntu中的静态networking接口设置 捕获'at'的输出 Windows 7 Pro无法连接到Windows 2000 Pro Workstation MongoDB活动状态失败 使用GPO时的Windows安全证书（组策略编辑器） XenApp是否需要Windowsterminal服务（远程桌面）许可证？ 带有PPPoE调制解调器的Windows Server 2012 RRAS / NAT 每当我尝试访问一个PHP文件（PHP 5.3.5）时，IIS 6会产生一个404错误， 如何比较CPU？ Hetzner VPS上不能使用外部IP 网站提供多个IP

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.

我看到日志： 

 [root@controller conf.d]# systemctl status httpd ● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Thu 2017-07-13 00:01:48 CST; 2min 5s ago Docs: man:httpd(8) man:apachectl(8) Process: 18076 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 18074 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 18074 (code=exited, status=1/FAILURE) Jul 13 00:01:48 controller systemd[1]: Starting The Apache HTTP Server...

Jul 13 00:01:48 controller systemd[1]: Unit httpd.service entered failed state. Jul 13 00:01:48 controller systemd[1]: httpd.service failed.

你看到这两行：

Jul 13 00:01:48 controller httpd [18074]：AH00526：/etc/httpd/conf.d/00-nova-placement-api.conf第23行的语法错误：
7月13日00:01:48控制器httpd [18074]：非法选项

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

  1 Listen 8778 2 3 <VirtualHost *:8778> 4 WSGIProcessGroup nova-placement-api 5 WSGIApplicationGroup %{GLOBAL} 6 WSGIPassAuthorization On 7 WSGIDaemonProcess nova-placement-api processes=3 threads=1 user=nova group=nova 8 WSGIScriptAlias / /usr/bin/nova-placement-api 9 <Directory "/"> 10 Order allow,deny 11 Allow from all 12 Require all granted 13 </Directory> 14 <IfVersion >= 2.4> 15 ErrorLogFormat "%M" 16 </IfVersion> 17 ErrorLog /var/log/nova/nova-placement-api.log 18 </VirtualHost> 19 20 Alias /nova-placement-api /usr/bin/nova-placement-api 21 <Location /nova-placement-api> 22 SetHandler wsgi-script 23 Options +ExecCGI 24 WSGIProgressGroup nova-placement-api 25 WSGIApplicationGroup %{GLOBAL} 26 WSGIPassAuthorization On 27 </Location> ~ ~ ~

23号线是正确的，为什么这里有错误？

编辑-1

权威如下： 

 [root@controller conf.d]# pwd /etc/httpd/conf.d [root@controller conf.d]# ll total 24 -rw-r-----. 1 root root 698 Jul 13 00:07 00-nova-placement-api.conf -rw-r-----. 1 root root 695 Jul 12 23:56 00-nova-placement-api.conf.bak -rw-r--r--. 1 root root 2926 Nov 20 2015 autoindex.conf -rw-r--r--. 1 root root 0 Jul 12 23:56 cp -rw-r--r--. 1 root root 366 Nov 20 2015 README -rw-r--r--. 1 root root 1252 Nov 20 2015 userdir.conf -rw-r--r--. 1 root root 824 Nov 20 2015 welcome.conf lrwxrwxrwx. 1 root root 38 Jul 12 15:27 wsgi-keystone.conf -> /usr/share/keystone/wsgi-keystone.conf

最后我发现错误是在24行不是23。

所以这是系统错误： 

 24 WSGIProgressGroup nova-placement-api

应该： 

 24 WSGIProcessGroup nova-placement-api
