systemctl start httpd 启动服务
systemctl restart httpd 重启服务
systemctl stop httpd 停止服务
systemctl reload httpd 重新加载配置文件（不终止服务）
systemctl status httpd 查看服务状态
systemctl enable httpd 开机自动启动
systemctl disable httpd 开机不自动启动
systemctl is-enabled httpd 查看特定服务是否为开机自启动
systemctl list-unit-files --type=httpd 查看各个级别下服务的启动与禁用情况
