-> ARM节点进行初始化，按照如下步骤进行:
->适用于 EulerOS 2.8 64bit 操作系统；
+> X86节点进行初始化，按照如下步骤进行: 适用于 `openEuler 20.03|22.03 64bit` 操作系统
 
 * 创建目录
 
   ```shell
-  mkdir /obs && mv ./{cpuNum,init.sh,obs_worker_euleros_aarch.sh,worker_ip_add} /obs
-  cd /obs
+  mkdir /obs && mv ./{obs_worker_cpuNum,obs_worker_init.sh,obs_worker_install_aarch64.sh,obs_worker_ip_add,obs_worker_update_config.sh} /obs && cd /obs
   ```
 
 * 赋予文件执行权限
 
   ```shell
-  chmod a+x ./init.sh
-  chmod a+x ./obs_worker_euleros_aarch.sh
+  chmod a+x ./obs_worker_init.sh
+  chmod a+x ./obs_worker_install_aarch64.sh
+  chmod a+x ./obs_worker_update_config.sh
+  sh ./obs_worker_install_x86.sh
   ```
 
-* 重启初始化方式
+* 设置节点重启检测
 
   ```shell
-  STR="@reboot /obs/init.sh"
+  STR="@reboot /obs/obs_worker_init.sh"
   ( echo "$STR" ) | crontab -
   ```
 
 * 说明
 
-  1. 可以使用两种方式初始化;
+  1. 直接执行`sh ./obs_worker_install_aarch64.sh`完成初始化；
 
-     第一种方式：直接执行`./obs_worker_euleros_aarch.sh`就可以完成初始化；适合于单个节点执行；完成初始化后，`cpuNum`中的值为`cpu`物理个数时，初始化正常；
-
-  2. 第二种方式：直接重启节点，自动完成初始化；初始化后，检查`cpuNum`中的值为`cpu`物理个数时，初始化正常；适合于远程批量执行；
-  
-  3. 如有异常，请检查日志文件:`/var/log/install_obs_worker.log`.
