我运行了 yum 更新，之后 HTTP Apache 服务器无法在我的 Centos 7 VM 上启动。
Apache 详细信息 -Apache/2.4.6 (CentOS) OpenSSL/1.0.1e-fips PHP/5.4.16
内核版本 -3.10.0-327.10.1.el7.x86_64
显示的内容如下systemctl。我不明白更新后哪里出了问题。
[root@localhost log]# systemctl status httpd.service

日志-xe 此命令显示以下数百行消息
Mar 28 20:33:31 localhost.localdomain pulseaudio[2055]: [alsa-sink] alsa-sink.c: Failed to set software parameters: Permission denied
答案1
检查 /var/log/httpd 日志，如果没有，请再次检查“yum update”。然后重新启动 httpd 服务。检查 /var/log/messages 和 /var/log/httpd 和 yum log。这样，您就可以识别问题。
