BlueOnyx 5209R で httpd が起動してない

何かのフックで /etc/httpd/conf/httpd.conf が壊れることがあり httpd が起動しないようだ。

[root@bots2 conf]# systemctl status httpd

失敗している環境
[root@bots2 conf]# ls -al /etc/httpd/conf/httpd.conf
-rw-r--r-- 1 root root 553  5月 15 07:52 /etc/httpd/conf/httpd.conf

[root@bots2 conf]# cat httpd.conf (こんなシンプルなのになっちゃう)

問題ない環境
[root@bots2 httpd]# ls -al /etc/httpd/conf/httpd.conf
-rw-r--r-- 1 root root 11272  5月 15 08:02 /etc/httpd/conf/httpd.conf

復旧してみた
[root@bots2 httpd]# rpm -q --whatprovides /etc/httpd/conf/httpd.conf
httpd-2.4.6-93.el7.centos.x86_64

[root@bots2 conf]# rm /etc/httpd/conf/httpd.conf
[root@bots2 conf]# yum reinstall httpd-2.4.6-93.el7.centos.x86_64
[root@bots2 conf]# ls -al /etc/httpd/conf/httpd.conf
-rw-r--r-- 1 root root 11757  5月 15 08:26 /etc/httpd/conf/httpd.conf
[root@bots2 conf]# systemctl start httpd

下部が戻らないので手動で。
[root@bots2 httpd]# tail conf/httpd.conf (問題ない環境)

IncludeOptional conf.d/*.conf
Include conf.modules.d/*.conf             <-- このへんが無いはず
Include /etc/httpd/conf/vhosts/site1      <-- このへんが無いはず
Include /etc/httpd/conf/vhosts/site2      <-- このへんが無いはず
Include /etc/httpd/conf/vhosts/preview

httpd.conf に重ねていってるパッチが当たりきってるかは不明だけど、動いているようだ。

一応、環境。
