# 恢复dds mongos节点
#### 操作步骤
1. 准备dds mongos节点的配置文件和目录。 
   rm -rf /compile/cluster-restore/mgs\*
   mkdir -p /compile/cluster-restore/mgs1/log
   mkdir -p /compile/cluster-restore/mgs2/log
   
   
2. 配置文件（restoreconfig/mongos_40301.yaml）。 
   ```
   net:
     bindIp: 127.0.0.1 
     port: 40301
     unixDomainSocket: {enabled: false}
   processManagement: {fork: true, pidFilePath: /compile/cluster-restore/mgs1/mongos.pid}
   sharding: {configDB: 'config/127.0.0.1:40303,127.0.0.1:40304,127.0.0.1:40305'}
   systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/mgs1/log/mongos.log}
   ```
   
   
3. 配置文件（restoreconfig/mongos_40302.yaml）。 
   ```
   net:
     bindIp: 127.0.0.1 
     port: 40302
     unixDomainSocket: {enabled: false}
   processManagement: {fork: true, pidFilePath: /compile/cluster-restore/mgs2/mongos.pid}
   sharding: {configDB: 'config/127.0.0.1:40303,127.0.0.1:40304,127.0.0.1:40305'}
   systemLog: {destination: file, logAppend: true, logRotate: reopen, path: /compile/cluster-restore/mgs2/log/mongos.log}
   ```
   
   
4. 启动mongo节点。 
   ./mongos -f restoreconfig/mongos_40301.yaml
   ./mongos -f restoreconfig/mongos_40302.yaml
   
   
 
#### 检查集群状态
通过dds mongos连接集群，检查数据状态。
./mongo --host 127.0.0.1 --port 40301
./mongo --host 127.0.0.1 --port 40302
