1.查看本地仓库，如果没有配置，就在这目录创建一个

cd到 /etc/yum.repos.d

#创建vim rpm.repo

[baseos]
name=baseos
baseurl=/mnt/BaseOS
gpgcheck=0
[appstream]
name=appstream
baseurl=/mnt/AppStream

Complete!

4.修改httpd配置文件

[root@ctrol yum.repos.d]# vim /etc/httpd/conf/httpd.conf

#不会设置行号，可以输入 set number

#在99行添加如下：ServerName 0.0.0.0:80

5.重启httpd服务

[root@ctrol ~]# systemctl restart httpd

stop停止

start 开启

status 查看运行状态

查看服务状态

[root@ctrol ~]# systemctl status httpd

6.查看当前可用IP地址

[root@ctrol ~]# ip ad
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

7.随便用一个IP 看是否有东西

# 可以用回环地址127.0.0.1或者你网卡上的

[root@ctrol ~]# curl 192.168.197.142

这时我们可以打开浏览器看看是否能访问

8.无法访问，原因是我们防火墙没有放行httpd服务

#可以使用--permanent 放行

--reload 重新加载

[root@ctrol ~]# firewall-cmd --permanent --add-service=http
success

[root@ctrol ~]# firewall-cmd --reload
success

看截图：哥们先进去了

9.那我们怎么自定义呢

#进入如下文件位置

[root@ctrol ~]# cd /var/www/html/

#查看是否有文件
[root@ctrol html]# ll
total 0

#重定向一个内容到文件
[root@ctrol html]# echo welcome to RHCE > index.html
[root@ctrol html]# ll
total 4
-rw-r--r--. 1 root root 16 Mar 20 22:35 index.html
[root@ctrol html]# cat index.html
welcome to RHCE

其实你也可以直接vim进去，改变他的内容，

[root@ctrol html]# vim index.html
[root@ctrol html]# cat index.html
welcome to RHCE
