Convert Command-Line Options to YAML将命令行选项转换为YAML

Starting in MongoDB 4.2, mongod and mongos accept --outputConfig command-line option to output the configuration used by the mongod/mongos instance.从MongoDB 4.2开始，mongod和mongos接受--outputConfig命令行选项以输出mongod/mongos实例使用的配置。

You can use this option to convert command-line options to YAML configuration.您可以使用此选项将命令行选项转换为YAML配置。

Examples示例

Convert mongod Command-Line Options to YAML将mongod命令行选项转换为YAML

Consider the following mongod invocation that uses the command-line options:考虑以下使用命令行选项的mongod调用：

mongod --shardsvr --replSet myShard  --dbpath /var/lib/mongodb --bind_ip localhost,My-Example-Hostname --fork --logpath /var/log/mongodb/mongod.log --clusterAuthMode x509 --tlsMode requireTLS  --tlsCAFile /path/to/my/CA/file  --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file

Include the --outputConfig command-line option to generate the corresponding YAML file.包括--outputConfig命令行选项以生成相应的YAML文件。

mongod --shardsvr --replSet myShard  --dbpath /var/lib/mongodb --bind_ip localhost,My-Example-Hostname --fork --logpath /var/log/mongodb/mongod.log --clusterAuthMode x509 --tlsMode requireTLS  --tlsCAFile /path/to/my/CA/file  --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file --outputConfig

The mongod outputs the following YAML to stdout and exits:mongod将以下YAML输出到stdout并退出：

net:
  bindIp: localhost,My-Example-Hostname
  tls:
    CAFile: /path/to/my/CA/file
    certificateKeyFile: /path/to/my/certificate/file
    clusterFile: /path/to/my/cluster/membership/file
    mode: requireTLS
outputConfig: true
processManagement:
  fork: true
replication:
  replSet: myShard
security:
  clusterAuthMode: x509
sharding:
  clusterRole: shardsvr
storage:
  dbPath: /var/lib/mongodb
systemLog:
  destination: file
  path: /var/log/mongodb/mongod.log

To create a configuration file, copy the generated content into a file and delete the outputConfig setting from the YAML.要创建配置文件，请将生成的内容复制到文件中，并从YAML中删除outputConfig设置。

Convert mongos Command-Line Options to YAML将mongos命令行选项转换为YAML

Consider the following mongos invocation that uses the command-line options:考虑以下使用命令行选项的mongos调用：

mongos --configdb myCSRS/cfg1.example.net:27019,cfg2.example.net:27019 --bind_ip localhost,My-Example-MONGOS-Hostname --fork --logpath /var/log/mongodb/mongos.log --clusterAuthMode x509 --tlsMode requireTLS  --tlsCAFile /path/to/my/CA/file  --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file

Include the --outputConfig command-line option to generate the corresponding YAML for the mongos instance:包括--outputConfig命令行选项，为mongos实例生成相应的YAML：

mongos --configdb myCSRS/cfg1.example.net:27019,cfg2.example.net:27019 --bind_ip localhost,My-Example-MONGOS-Hostname --fork --logpath /var/log/mongodb/mongos.log --clusterAuthMode x509 --tlsMode requireTLS  --tlsCAFile /path/to/my/CA/file  --tlsCertificateKeyFile /path/to/my/certificate/file --tlsClusterFile /path/to/my/cluster/membership/file --outputConfig

The mongos outputs the following YAML to stdout and exits:mongos将以下YAML输出到stdout并退出：

net:
  bindIp: localhost,My-Example-MONGOS-Hostname
  tls:
    CAFile: /path/to/my/CA/file
    certificateKeyFile: /path/to/my/certificate/file
    clusterFile: /path/to/my/cluster/membership/file
    mode: requireTLS
outputConfig: true
processManagement:
  fork: true
security:
  clusterAuthMode: x509
sharding:
  configDB: myCSRS/cfg1.example.net:27019,cfg2.example.net:27019
systemLog:
  destination: file
  path: /var/log/mongodb/mongos.log

To create a configuration file, copy the generated content into a file and delete the outputConfig setting from the YAML.要创建配置文件，请将生成的内容复制到文件中，并从YAML中删除outputConfig设置。
