Alibaba Cloud ESC instance, change the port number of the sshl connection

first of all

• The network I use is the forbidden port 22, so I need to modify the ssh port number.

First of all, select the appropriate port number, which cannot be the same as the existing port number.
Then visit this connection: https://ecs.console.aliyun.com/#/securityGroupDetail/region/cn-beijing/groupId/sg-2zebighqoqouop7n8sa2/detail/intranetIngress

Add this security group rule.

After logging in to the system, mine is the ubuntu system. then

# 1.进入配置文件 
vi /etc/ssh/sshd_config
# 2.修改端口号为 8008   根据自己设置的端口号改
port 8008

# 不要忘记第三步，重启服务，使修改的配置文件生效
service sshd restart

the end

Now we can use port 8008 to access our server!
