Record the management and resolution process of expiration of the domain name bound to the Pagoda panel and inability to log in to the server

When this operation and maintenance article was recorded, the title was really difficult to define. I actually felt uncomfortable and satisfied after modifying it several times. The main reason was that this netizen’s problem was too amazing. Theoretically, no matter we use the Pagoda panel, one-click WEB script, or even a working environment compiled and installed by ourselves, security is a must. However, this netizen can't enter after setting various security settings. Isn't it amazing? ?

The situation of this netizen is like this. He may have configured the Pagoda Panel in the Alibaba Cloud server a long time ago to build a website. Of course, the website is running normally, and in view of security considerations, direct IP access to the panel management has been canceled, and It is to bind my own idle domain name. When I needed to manage it yesterday, I found that the domain name had expired and was registered by others. At the same time, his server also banned the SSH port for security reasons, and the server's ROOT password was also forgotten.

This netizen’s server security was really good. In the end, even he couldn’t access the management website and server. So I came to help solve this problem and recorded the whole process. There were still some screenshots that were not taken during the process, but there was no problem with the whole idea process.

First, log in to the server and modify the port through VNC

This netizen is using Alibaba Cloud server, so he is going to log in to Alibaba Cloud server VNC and start the server SSH port first, because he needs to enter SSH to obtain the panel information.

Here we definitely didn’t know the password when we logged in to the VNC remote connection for the first time, so we reset a new password. The password is six digits, and we cannot log in yet after setting it up.

Second, reset the server ROOT password

This classmate also forgot his server password, so we need to reset the server password first. After the reset, we need to restart the server to take effect.

Third, reset the server SSH port

According to this netizen’s complaint, port 22 should have been defaulted to at first, and then he disabled the port. So we need to reset the port and start. Here you can refer to the article "How to modify the SSH port of Linux server in CentOS7". Because the current server also uses the centos7 system, there is no problem. If it is another system image, it will be different.

The snail is no longer a burden here. I saw him disabling port 22, so I deleted the # in the corresponding configuration file and wrote it into the firewall to open the port.

Fourth, unbind the domain name of the pagoda panel

The snail is in front\\"The Pagoda Panel lifts/changes domain name binding restrictions and returns to the IP binding panel\\" article also separately records that we only need to log in to SSH and go to\\"/www/server/ Panel/data/domain.conf\\" file, delete the already bound domain name or change other domain names to unbind the domain name.

Snail directly deletes the domain name binding of this netizen.

Fifth, check the configuration information of the pagoda panel

/etc/init.d/bt default

Here we can log in to SSH normally, and then enter the command to see the account information of the default Pagoda account.

Is it starting to become clear? See the login entrance, user name and password of the Pagoda panel of the server configuration. However, the password is the initial password set for the panel, and the password you have changed later will not be seen here. But fortunately, this netizen remembered the password. If he doesn't remember it, it's okay, he can reset the password.

In summary, just like this, Snail recovered this netizen’s pagoda panel. In the future, when we set up server security, we must also record the server information, otherwise it will be really troublesome when we need to use it later. By the way, this classmate must have never backed up the website. No matter how good the server security is, the data security is not backed up at all.
