由于apache错误，我正面临Centos 7 VPS的一个问题：
当我做：
[root@vm01 ~]# apachectl restart Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details. 有这个状态错误：
[root@vm01 ~]# systemctl status httpd.service * httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Fri 2016-12-16 16:58:10 WET; 4min 41s ago Docs: man:httpd(8) man:apachectl(8) Process: 555 ExecStop=/bin/kill -WINCH ${MAINPID} (code=exited, status=1/FAILURE) Process: 553 ExecStart=/usr/sbin/httpd $OPTIONS -DFOREGROUND (code=exited, status=1/FAILURE) Main PID: 553 (code=exited, status=1/FAILURE) Dec 16 16:58:10 vm01 systemd[1]: Starting The Apache HTTP Server...

Dec 16 16:58:10 vm01 systemd[1]: Unit httpd.service entered failed state. Dec 16 16:58:10 vm01 systemd[1]: httpd.service failed.
和期刊打印：

我一直在寻找这个解决scheme，但没有运气。 你能帮我吗？
问候，海梅
你发布的journalctl输出显然是无用的。 正如许多启动信息。 我通常使用journalctl -xe向后工作。 如果这没有显示任何有用的东西，你可以尝试看看你的httpd错误日志中应该包含一些相关的信息。
