  destination: file
  logAppend: true

目錄介紹
/data/wyd/mongodb下的目錄內(nèi)容如下
backup(備份) log(日志) pid(pid文件) script shard-a-primary(數(shù)據(jù)庫目錄)

cacheSize是指系統(tǒng)分配給mongod用的內(nèi)存，比如你系統(tǒng)有三十G內(nèi)存，你可以分配二十四G內(nèi)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
