openstack安装时检测apache无法启动

agangliu0400

　　    在安装openstack kilo版本时有一步检测apache无法启动，搜遍了google没有搜到相关信息只好自己动手了，我用的是CentOS-7-x86_64位系统，报错信息如下：
　　一、
　　ERROR : Error appeared during Puppet run: 192.168.209.143_horizon.pp
　　Error: Could not start Service[httpd]: Execution of '/usr/bin/systemctl start httpd' returned 1: Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
　　

　　按照提示信息执行了一下"journalctl -xe"，其中找到了以下信息：
　　

　　Dec 29 11:06:33 controller httpd[29959]: AH00526: Syntax error on line 11 of /etc/httpd/conf.d/fcgid.conf:
　　Dec 29 11:06:33 controller httpd[29959]: Invalid command 'FcgidIPCDir', perhaps misspelled or defined by a module not included in the server configuration
　　Dec 29 11:06:33 controller systemd[1]: httpd.service: main process exited, code=exited, status=1/FAILURE
　　Dec 29 11:06:33 controller kill[29963]: kill: cannot find process ""
　　Dec 29 11:06:33 controller systemd[1]: httpd.service: control process exited, code=exited status=1
　　Dec 29 11:06:33 controller systemd[1]: Failed to start The Apache HTTP Server.
　　

　　其中两段红色英文字体提示/etc/httpd/conf.d/fcgid.conf 这个文件有无效的命令Invalid command 'FcgidIPCDir'，有可能是拼写错误也有可能是模块未加载导致，看文件全部信息如下：
　　

　　
　　[root@controller ~]# cat  /etc/httpd/conf.d/fcgid.conf
　　# This is the Apache server configuration file for providing FastCGI support
　　# through mod_fcgid
　　#
　　# Documentation is available at
　　# http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html
　　

　　# Use FastCGI to process .fcg .fcgi & .fpl scripts
　　AddHandler fcgid-script fcg fcgi fpl
　　

　　# Sane place to put sockets and shared memory file
　　FcgidIPCDir /run/mod_fcgid
　　FcgidProcessTableFile /run/mod_fcgid/fcgid_shm
　　

　　这是一个调用mod_fcgid模块并提供FastCGI 的apache server的配置文件，一看文件中确实没有加载mod_fcgid模块，
　　

　　所以在文件中加载该模块
　　    LoadModule fcgid_module modules/mod_fcgid.so
　　

　　完整文件如下：
　　
　　fcgid.conf
　　

　　# This is the Apache server configuration file for providing FastCGI support
　　# through mod_fcgid
　　#
　　# Documentation is available at
　　# http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html
　　LoadModule fcgid_module modules/mod_fcgid.so
　　# Use FastCGI to process .fcg .fcgi & .fpl scripts
　　AddHandler fcgid-script fcg fcgi fpl
　　# Sane place to put sockets and shared memory file
　　FcgidIPCDir /var/run/mod_fcgid
　　FcgidProcessTableFile /var/run/mod_fcgid/fcgid_shm
　　
在启动一下
　　[root@controller ~]# apachectl start
　　[root@controller ~]# apachectl status
　　* httpd.service - The Apache HTTP Server

openstack安装horizon时修改了http的配置文件，其中没有加载“conf.modules.d/*.conf”，
　　所以在/etc/httpd/conf/httpd.conf 中加载即可；
　　

　　#echo 'Include conf.modules.d/*.conf' >> /etc/httpd/conf/httpd.conf
