芒果數據庫配置文件

配置文件1

# mongod.conf
systemLog:
  destination: file
  logAppend: true
storage:
  journal:
    enabled: true
  directoryPerDB: true
  engine: wiredTiger
  wiredTiger:
    engineConfig:
      cacheSizeGB: 2
      directoryForIndexes: true
    indexConfig:
      prefixCompression: true
processManagement:
  fork: true
net:
  port: 27017

目錄介紹
/data/wyd/mongodb下的目錄內容如下
backup(備份) log(日志) pid(pid文件) script shard-a-primary(數據庫目錄)

cacheSize是指系統分配給mongod用的內存，比如你系統有三十G內存，你可以分配二十四G內存給Mongodb

啟動

numactl --interleave=all mongod -f /etc/mongod.conf \
--dbpath /data/wyd03/mongodbard-a-primary \
--logpath /data/wyd03/mongodb/logard-a-primary.log \
--pidfilepath /data/wyd03/mongodb/pidard-a-primary.pid --port 27021

指定不一樣的pid和端口這樣就可以起啟多個不一樣的進程
