Why can't it run? Reinstalled, the httpd.conf file is standard. Installed on Centos7

Answer 1

Send us the output
of systemctl status httpd.service"
and
"journalctl -xe"

Answer 2

Check the content /usr/lib/systemd/system/httpd.service
If it doesn't match this, then fix it:

[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/usr/sbin/httpd $OPTIONS -k start
ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
ExecStop=/usr/sbin/httpd $OPTIONS -k graceful-stop
PrivateTmp=true
# If you have 90 seconds reload problem - uncomment several lines below (mixed - worked for me)
#LimitNOFILE=infinity
#KillMode=mixed
#KillMode=none
#TimeoutStopSec=10

[Install]
WantedBy=multi-user.target

After fixing -systemctl daemon-reload
