启动httpd服务，失败：
[root@test vmdb]# service httpd restart Stopping httpd: [FAILED] Starting httpd: Syntax error on line 17 of /etc/httpd/conf.d/cfme-https-application.conf: SSLCertificateFile: file ‘/var/www/miq/vmdb/certs/server.cer‘ does not exist or is empty [FAILED]
网上搜了下，说与selinux相关，想到之前设置samba服务，开机自启动，并允许外部访问，曾经修改过selinux配置。
然后关闭selinux：
setenforce 0
再启动httpd服务：
service httpd start
启动成功！
