解决

只需要开启防火墙即可。

【1】先通过systemctl status firewalld命令查看一下防火墙的状态，发现当前是dead状态，即防火墙未开启。

[root@xxx ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

【2】通过systemctl start firewalld命令开启防火墙

[root@xxx ~]# systemctl start firewalld

【3】 防火墙开启后，再次查看防火墙状态为running即可。

[root@xxxx ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: active (running) since Mon 2024-02-19 22:40:51 CST; 40s ago
     Docs: man:firewalld(1)
 Main PID: 664 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─664 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid
