编译安装httpd
实验准备：
httpd包：httpd-2.4.41.tar.gz
apr依赖包：apr-1.7.0.tar.bz2、apr-util-1.6.1.tar.bz2

- 创建service unit文件（使这个服务受system监控）

#如果出现以上情况，关闭服务特别慢，重启服务特别慢
#重新加载服务配置文件
[root@centos7 ~]$systemctl restart httpd
Warning: httpd.service changed on disk. Run 'systemctl daemon-reload' to reload units.
^C
[root@centos7 ~]$systemctl daemon-reload
- systemctl daemon-reload
- 重新加载某个服务的配置文件，如果新安装了一个服务，归属于 systemctl 管理，要是新服务的服务程序配置文件生效，需重新加载
