The tools used for this upgrade are provided by Su Yan
1. Preparations before upgrading
1.1 Precautions
● The migration tool is installed in the auxiliary machine (the machine that does not perform system migration)
● The auxiliary machine should reserve at least 1.6G memory space for the installation of the migration tool.
● Special requirements for turning off the firewall and SELinux before installation
● The tool installation environment needs to open tool port 18082
1.2 System to be upgraded
This upgrade system takes centos7.6 as an example. The upgrade software supports centos7.x, redhat7.x, bclinx7.x to bclinux_for_openEuler21.10
The upgrade process does not have absolute requirements for the performance of the upgraded system, but at least 2G of space must be reserved for users to install the upgrade software, and a certain amount of space must be reserved for users to back up the system according to time conditions (the specific reserved space depends on the actual size of the system)
1.3. Auxiliary machine
The upgrade process requires at least one auxiliary machine. The upgrade software needs to be installed on the auxiliary machine. The auxiliary machine and the node to be upgraded cannot be the same machine.
The auxiliary machine operating system needs to be centos7.6 or bclinux7.6
1.3 Upgrade software
The upgrade software provides Su Yan with the Tianyuan Yixing migration tool (Euler). Currently, the Tianyuan Yixing migration tool (Euler) only supports x86_64 and ARM 64-bit servers, and does not support IBM PowerPCLE and other architecture servers.
If the intranet upgrade does not correspond to bclinux-for-euler2110, you need to mount the intranet yum source through the iso image file.
2. Install and upgrade software on auxiliary machine
2.1. Auxiliary machine preparation operation
Execute the following command to check whether the firewall is enabled
systemctl status firewalld
Displaying "inactive" means the firewall is not turned on
Displaying "active" indicates that the firewall is on.
[root@fuzhuji_zfk ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2023-06-21 10:47:53 EDT; 5min ago

If it is not enabled, execute the following command to check whether the port is enabled.
[root@fuzhuji_zfk ~]# firewall-cmd --query-port=18082/tcp
no
The prompt "no" indicates that the port is not open.
Execute the following command to permanently open the port:
firewall-cmd --add-port=18082/tcp --permanent
[root@fuzhuji_zfk ~]# firewall-cmd --add-port=18082/tcp --permanent
success
After reloading the configuration, check whether port 18082 is opened.
firewall-cmd --reload
firewall-cmd --query-port=18082/tcp
[root@fuzhuji_zfk ~]# firewall-cmd --reload
success
[root@fuzhuji_zfk ~]# firewall-cmd --query-port=18082/tcp
yes
[root@fuzhuji_zfk ~]#
2.2. Install the upgrade tool
If there is no yum source available for the auxiliary machine, you need to manually upload the rpm package of bclinux-sysmt-core, then make the local source through the local image, and then install the tool and its required dependencies through yum.
Upload the installation package to any location on the auxiliary machine node (this time, /mnt/soft is used as an example)
cd /mnt
mkdir soft
cd soft
ls
[root@fuzhuji_zfk mnt]# cd /mnt
[root@fuzhuji_zfk mnt]# mkdir soft
[root@fuzhuji_zfk mnt]# cd soft
[root@fuzhuji_zfk soft]# ls

3. Configure local yum source
Since the system upgrade is performed on the intranet, the installation package required for downloading and upgrading can only be obtained through the intranet yum source. Here we obtain the intranet yum source by mounting the Euler image.
3.1. Upload the image source to the secondary machine
Store in the directory BCLinux-for-Euler-21.10-dvd-x86_64-230324.isoof the auxiliary node/mnt/iso
[root@fuzhuji_zfk service]# cd /mnt/iso/
[root@fuzhuji_zfk iso]# ls
BCLinux-for-Euler-21.10-dvd-x86_64-230324.iso
3.2. Install httpd and start the service
You also need to upload the httpd installation package to the auxiliary machine before installing it.
Upload the rpm installation package of httpd to /mnt/softthe directory for installation

5.1 yum configuration issues
To select the mounted upgrade source image, select the everything version.
For exampleBCLinux-for-Euler-21.10-everything-x86_64
Mirror download address: https://mirrors.cmecloud.cn/bclinux/oe21.10/ISO/x86_64/release/
Otherwise, there may be missing files.
5.2. Missing database
The upgrade software has built-in database for upgrading centos7.6, bclinux7.6 to openeuler. If you upgrade centos7.x, or bclinux7.x, redhat7.x, you need to download the corresponding database.
Download address: https://repo.oepkgs.net/openEuler/rpm/openEuler-20.03-LTS-SP1/contrib/x2openEuler/x86_64/Packages/
