步骤 1 准备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

步骤 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}

步骤 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}

步骤 4 启动mongo节点。

./mongos -f restoreconfig/mongos_40301.yaml

./mongos -f restoreconfig/mongos_40302.yaml
