# JobGateway手动更新服务客户端
![](https://support.huaweicloud.com/cmpntguide-lts-mrs/public_sys-resources/note_3.0-zh-cn.png)
本章节适用于MRS 3.3.1及之后版本。
#### 操作场景
该操作指导用户在MRS集群添加多服务更新服务客户端失败时，手动更新客户端。
#### 前提条件
- Manager上已成功添加服务。
- 仅适用于Spark 、Hive 、Flink服务。
 
#### 操作步骤
1. 登录Manager页面，选择"集群 \> 服务 \> JobGateway \> 实例"，查看所有JobServer实例节点IP。
2. 获取部署了JobServer的节点中，IP最小的节点（以下简称"最小IP节点"）。若最小IP节点更新服务客户端失败，执行[3]， 否则执行[4]。
   
   ![](https://support.huaweicloud.com/cmpntguide-lts-mrs/public_sys-resources/note_3.0-zh-cn.png)
   - 若JobServer部署节点IP为：192.168.0.192、192.168.0.168、192.168.0.23 ， 则最小IP为192.168.0.23。
   
   - 脚本支持一次性更新一个或多个服务客户端。
    
   
   

3. 以omm用户登录最小IP节点，执行更新服务客户端的脚本。
   
   **cd** **${BIGDATA_HOME}/FusionInsight_JobGateway_\*/install/FusionInsight_JobGateway-\*/adapter/script**
   **dos2unix update-multi-service-client.sh**
   **sh update-multi-service-client.sh** *服务1 服务2* **......**
   
   
4. 以omm用户登录其他更新服务客户端失败的节点上分别执行如下命令：
   
   **TIME_RECORD_FILE=${BIGDATA_HOME}/FusionInsight_JobGateway\*/install/FusionInsight-JobGateway\*/job-gateway/job-server/tmp/multi-service-update-time**
   **date +"%Y-%m-%d %H:%M:%S" \> "${TIME_RECORD_FILE}"**
   **cat ${TIME_RECORD_FILE}** （确保文件生成并写入时间）
   **cd ${BIGDATA_HOME}/FusionInsight_JobGateway_\*/install/FusionInsight_JobGateway-\*/adapter/script**
   **dos2unix update-multi-service-client.sh**
   **sh update-multi-service-client.sh** *服务1 服务2* **......**
   **例如**：
   更新Hive-1 Spark-1服务客户端时部分节点更新失败，其中最小IP节点更新失败。修复如下：
   - 在最小IP节点执行更新服务客户端脚本： **cd** **/opt/Bigdata/FusionInsight_JobGateway_8.5.0/install/FusionInsight-JobGateway-1.0.0/adapter/script**
     **dos2unix update-multi-service-client.sh**
     **sh update-multi-service-client.sh** *Hive-1 Spark-1*
     ```

     ```
     
   
   
   
   - 在其他失败的节点上分别执行如下操作： **TIME_RECORD_FILE=${BIGDATA_HOME}/** **FusionInsight_JobGateway_8.5.0/install/FusionInsight-JobGateway-1.0.0/job-gateway/job-server/tmp/** **multi-service-update-time**

5. 删除所有JobServer所在节点时间戳，需要在所有的JobServer节点执行如下命令： 
   **TIME_RECORD_FILE=${BIGDATA_HOME}/FusionInsight_JobGateway\*/install/FusionInsight-JobGateway\*/job-gateway/job-server/tmp/multi-service-update-time**
   **rm -f ${TIME_RECORD_FILE}**
