1.查看httpd的服务状态：显示httpd单元，无法找到服务。
[root@localhost ~]#systemctl status httpd
Unit httpd.service could not be found.2. 使用yum安装httpd服务，下面是安装过程：
[root@localhost ~]#yum install httpd
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

Complete!3.再次查看httpd服务的状态
[root@localhost ~]#systemctl status httpd
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disab
Active: inactive (dead) #显示死了，也就是关闭状态
Docs: man:httpd(8)
man:apachectl(8)4.使用start开启httpd服务
[root@localhost ~]#systemctl start httpd使用ss -nlt确认80端口打开
[root@localhost /etc/httpd/conf.d]#ss -nlt
State Recv-Q Send-Q Local Address:Port Peer Address:Port

5.再次检查httpd服务的状态
[root@localhost ~]#systemctl status httpd
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disab
Active: active (running) since Fri 2019-10-11 19:16:34 CST; #显示服务已经跑起来了，已启用
Docs: man:httpd(8)
man:apachectl(8)
Main PID: 9866 (httpd)
Status: "Processing requests..."
Tasks: 6
CGroup: /system.slice/httpd.service
├─9866 /usr/sbin/httpd -DFOREGROUND
├─9867 /usr/sbin/httpd -DFOREGROUND
├─9868 /usr/sbin/httpd -DFOREGROUND
├─9869 /usr/sbin/httpd -DFOREGROUND
├─9870 /usr/sbin/httpd -DFOREGROUND
└─9871 /usr/sbin/httpd -DFOREGROUND

7.如果添加了桥接网卡，通过浏览器还是连接不上虚拟机IP地址的话，可以使用下面的命令关闭防火墙
[root@localhost ~]#systemctl disable --now firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. 8.关闭防火墙后，再次确认httpd服务是否开启
[root@localhost ~]#systemctl status httpd
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; disab
Active: active (running) since Fri 2019-10-11 19:16:34 CST; #显示服务已经跑起来了，已启用

man:apachectl(8)

Hint: Some lines were ellipsized, use -l to show in full. 9.确认开启httpd服务后，此时就可以使用浏览器进行访问了
