1、启动防火墙
[root@share ~]# systemctl start firewalld.service

2、指定IP与端口
[root@share ~]# firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.100.77" port protocol="tcp" port="5432" accept"

指定多个端口（连续）

[root@share ~]# firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.100.77" port protocol="tcp" port="13330-13339" accept"

[root@share ~]# firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.100.0/24" port protocol="tcp" port="5432" accept"

3、重新载入，使配置生效
