Recently, a VPS host changed its IP address and just installed a DA panel (DirectAdmin) on it. After changing the IP address, it needs to update the authorization. After a trial, I found that the key authorization is a little different from the previous command, and the online search is still the same as the previous operation, so I recorded it so that I don't need to search next time I use it. I just changed the IP address, and the operating system remains unchanged CentOS7.9 64bit, because it is an integer

Pure record. I found that CentOS9 is very different from my most commonly used CentOS7. X in use, such as the location of the network card file, the command to restart the network card, the content of the network configuration file, etc., so the record is easy to read when you come across it next time. It is not necessary to use the search engine every time. In particular, most of the information found in a search is useless information. The network card configuration file path of CentOS9 is in/etc/NetworkManage

There are fewer and fewer vendors that still use the xen architecture chicken. Some of those who used xen previously have been converted to the kvm architecture. Recently, Zhao Rong also has a VPS that has been converted from xen to kvm. Unfortunately, I installed ubuntu18.04 before, and found that after the conversion, the system could not be started normally. I just wanted to do something, so I tried to find a solution by myself, mainly by recording, It is convenient to show it next time, even if it is not exactly the same, it is also good to learn from it

The memory is getting worse and worse. It's a pure record. I forgot it for a while. In addition, CentOS is the most commonly used one, but many friends prefer ubuntu or debian. Today, I met a virtual machine in the ubuntu18.04 system and changed its IP address. It's not good to change/etc/network/interfaces normally. Record it here to avoid the trouble of going to bind every time. Ubuntu 18.04 makes

In 2013, the tribe recorded part of the use of the find command once, and the reason for this is that it is sad to find that a station has been invaded and changed a lot of files. At this time, the find command is used to find files that have been modified in a certain period of time, so it can be picked up again for the next reference.

We once shared the VPS host information of each machine room of HostYun, and also conducted a simple test on some machine room lines.

Help online friend CentOS7.9 mount a disk, only to find that he has never attached a single 4TB disk before. After all, VPS is the most popular way to play, and it can't use such a large disk. The machine defaults to 1TB+4TB, and the installation system uses 1TB disk. Now you need to attach 4TB to/home as a data disk, and inertial thinking fdisk will be available once, It is found that there is only 2TB... because the fdisk tool can only create 2TB partitions at most, and those exceeding 2TB

I once shared an article about migrating from CP to DA in 2013. Today, looking back, it is a little cumbersome. At present, DirectAdmin (hereinafter referred to as DA) has a similar one click function, while WHM/cPanel (hereinafter referred to as CP) only needs to provide a complete backup file. Sometimes we buy VPS to install a DA panel, and want to migrate the websites on the CP panel of the previous virtual host, Now I will simply record the operation process for convenience
