本次升级使用工具为苏研提供
1. 升级前准备操作
1.1 注意事项
● 迁移工具安装在辅助机中（不进行系统迁移的机器）
● 辅助机至少给迁移工具的安装预留 1.6G 内存空间
● 安装之前需要关闭防火墙和 SELinux 的特殊要求
● 工具安装环境需开启工具端口 18082
1.2 待升级系统
本次升级系统以centos7.6为例，升级软件支持centos7.x，redhat7.x，bclinx7.x到bclinux_for_openEuler21.10
升级过程对待升级系统性能没有绝对要求，但是要至少预留2G空间用户安装升级软件，根据时间情况预留一定空间用户备份系统(具体预留空间根据系统实际大小而定)
1.3. 辅助机
升级过程至少需要一台辅助机，升级软件需要安装在辅助机，辅助机和待升级节点不能是同一台机器
辅助机操作系统需要为centos7.6或者bclinux7.6
1.3 升级软件
升级使用软件为苏研提供天元易行迁移工具（欧拉），目前天元易行迁移工具（欧拉）仅支持 x86_64 和 ARM 64 位服务器，不支持 IBM PowerPCLE 等 架构服务器
在内网升级如果没有对应bclinux-for-euler2110，则需要通过iso镜像文件挂载内网yum源
2. 辅助机安装升级软件
2.1. 辅助机准备操作
执行以下命令查看防火墙是否开启
systemctl status firewalld
显示“inactive”表示防火墙没有开启
显示“active”表示防火墙开启。
[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

如果没有开启，执行以下命令查看端口是否开通
[root@fuzhuji_zfk ~]# firewall-cmd --query-port=18082/tcp
no
提示“no”表示端口未开通。
执行以下命令永久开通端口：
firewall-cmd --add-port=18082/tcp --permanent
[root@fuzhuji_zfk ~]# firewall-cmd --add-port=18082/tcp --permanent
success
重载配置后查看是否开通18082端口
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. 安装升级工具
若辅助机器无可用 yum 源，需手动上传 bclinux-sysmt-core 的 rpm 包，然后通过本地镜像制作本地源， 再通过 yum 安装工具及其所需要的依赖。
将安装包上传到辅助机节点任意位置(本次以/mnt/soft为例)
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
bclinux-sysmt-core-2.0.0-1.x86_64.rpm
安装此rpm包
yum install -y bclinux-sysmt-core-2.0.0-1.x86_64.rpm
[root@fuzhuji_zfk soft]# yum install -y bclinux-sysmt-core-2.0.0-1.x86_64.rpm

3. 配置本地yum源
由于升级系统是在内网进行，下载升级所需要的安装包只能通过内网yum源获取，这里我们通过挂载欧拉镜像的方式获取内网yum源
3.1. 上传镜像源到辅助机
将 BCLinux-for-Euler-21.10-dvd-x86_64-230324.iso 存放到辅助结点的/mnt/iso 目录下
[root@fuzhuji_zfk service]# cd /mnt/iso/
[root@fuzhuji_zfk iso]# ls
BCLinux-for-Euler-21.10-dvd-x86_64-230324.iso
3.2. 安装httpd并启动服务
同样需要上传httpd的安装包到辅助机，在进行安装
将httpd的rpm安装包上传到/mnt/soft目录下进行安装

3.3. 挂载镜像
在目录 /var/www/html下创建目录euler2110 ,然后将欧拉镜像挂载在此目录
欧拉镜像版本要选择everything
[root@fuzhuji_zfk /]# cd /var/www/html/
[root@fuzhuji_zfk html]# mkdir euler2110
[root@fuzhuji_zfk html]# mount -o loop /mnt/iso/BCLinux-for-Euler-21.10-everything-x86_64-230324.iso /var/www/html/euler2110/

4. 系统升级
4.1. 登录x2openEuler
在浏览器（谷歌浏览器72.0及以上版本）中打开：https://部署辅助机的ip:端口号/x2openEuler/#/login
第一次进入登录界面输入用户名和密码，用户名默认为x2openEulerAdmin，密码为自己设定。设定好密码后，将重新进入登录页面。用前面设定好的密码重新登录。

5. 问题说明
5.1 yum配置问题
选择挂载的升级源镜像要选择everything版本
例如BCLinux-for-Euler-21.10-everything-x86_64
镜像下载地址:https://mirrors.cmecloud.cn/bclinux/oe21.10/ISO/x86_64/release/
否则有可能出现缺少文件玩儿
5.2. 缺少database
升级软件已经内置升级centos7.6，bclinux7.6到openeuler的database，如升级centos7.x，或者bclinux7.x，redhat7.x则需要下载对应的database
