1.httpd解决方案

​ Job for httpd.service failed because the control process exited with error code.see “systemctl status httpd.service” and “journalctl -xe” for details.

这个提醒 会让你去查看当前状态日志，查看状态日志时基本上你会发现 一些服务处在 fail 状态 基本上就是httpd服务没能够起来。

1.杀掉这个进程就可以：

先ps –aux | grep http
第二行数字就是进程pid号
Kill -9 pid号 即可杀掉进程
杀完之后 重启reboot 再ps –aux | grep http 确保httpd进程被杀掉 若发现无法杀掉进程 往下看

2. 如果杀掉进程的话，重启进程还存在，就代表成了僵尸进程，就重新安装哈httpd
步骤如下：
先用yum卸载httpd和mod_wsgi，
命令：yum remove httpd mod_wsgi;
然后再安装yun -y install httpd mod_wsgi 就可以了
安装完成后 service httpd restart 即可 问题基本排除

vim /etc/glance/glance-api.conf
 
vim /etc/glance/glance-registry.conf

[paste_deploy]
flavor = keystone
  • 重新启动服务
