ソースビルドしたApache最新バージョンをsystemdに登録したい
何番煎じかわからない出がらし記事です。

環境

apache24 のインストールディレクトリは/opt/rh/httpd24/root

.service ファイルを書く

httpd24.service

[Unit]
Description=The Apache2.4 HTTP Server
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/httpd24
ExecStart=/opt/rh/httpd24/root/bin/httpd -k start
ExecReload=/opt/rh/httpd24/root/bin/httpd -k restart
ExecStop=/opt/rh/httpd24/root/bin/httpd -k stop

[Install]
WantedBy=multi-user.target

EnvironmentFile=/etc/sysconfig/httpd24は無くても大丈夫

systemd に登録する

$ sudo su -
$ cd /opt/rh/httpd24/root/conf
$ cat > httpd24.service <<EOF
  (上記のテキストをペースト)
EOF
$ chmod 644 httpd24.service
$ chown root httpd24.service
$ systemctl link $PWD/httpd24.service
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd24.service to /opt/rh/httpd24/root/conf/httpd24.service.
