一、yum安装apache

yum -y install httpd

二、启动apache服务及设置开机启动

systemctl start httpd

systemctl enable httpd

三、设置防火墙允许apache端口（关闭跳过此操作）HTTP=80、HTTPS=443

firewall-cmd --permanent --zone=public --add-service=http

firewall-cmd --permanent --zone=public --add-service=https

重启防火墙

firewall-cmd --reload

四、检查apache服务的状态及版本

状态Active: active (running)代表已启动

[root@123 ~]# systemctl status httpd
● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
   Active: active (running)  since 五 2021-01-15 14:42:27 CST; 23s ago
     Docs: man:httpd(8)
           man:apachectl(8)
 Main PID: 1845 (httpd)
   Status: "Total requests: 0; Current requests/sec: 0; Current traffic:   0 B/sec"

           ├─1848 /usr/sbin/httpd -DFOREGROUND
           ├─1849 /usr/sbin/httpd -DFOREGROUND
           ├─1850 /usr/sbin/httpd -DFOREGROUND
           └─1851 /usr/sbin/httpd -DFOREGROUND

版本

[root@123 ~]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Nov 16 2020 16:18:20

五、验证安装是否成功

在浏览器输入服务器IP地址，端口默认是80所以不用输入，如果有改动就需要输入IP:端口

systemctl管理Apache服务命令

systemctl stop httpd     ------关闭
systemctl start httpd    ------开启
systemctl restart httpd  ------重启
systemctl disable httpd  ------禁止开机启动
systemctl enable httpd   ------开机启动
