> 网络资源 > CentOS 8修改ssh默认端口
1、编辑sshd配置文件，将#Port 22取消注释改成您想修改的端口，如：22345
vi /etc/ssh/sshd_config
2、将新端口添加至防火墙规则
firewall-cmd --zone=public --add-port=22345/tcp --permanent firewall-cmd --reload
3、向SELinux中开放新端口，需要先安装semanage及其依赖包policycoreutils-python-utils：
yum provides semanage yum -y install policycoreutils-python-utils
添加开放端口：
semanage port -a -t ssh_port_t -p tcp 22345
4、重启SSHD服务
systemctl restart sshd.service
此时就可以用新端口连接了
