mongodb一些參數可以在配置文件中配置
mongodb啓動方式可以爲mongodb --dbpath db路徑 --config config路徑
配置文件存放在/etc/mongod.conf,路徑也可以自己設置
#------------------------------一下是內容---------------------------------------
# mongo.conf
# 日誌文件存放位置
logpath=/var/log/mongo/mongod.log
# 以追加方式寫入日誌
logappend=true
# 是否已守護進程方式運行(後臺運行)
fork = true
# 設置端口(默認27017)
#port = 27017
# 數據庫文件保存位置
dbpath=/var/lib/mongo
# Enables periodic logging of CPUutilization and I/O wait
# 啓用定期記錄CPU利用率和 I/O 等待
#cpu = true
# Turn on/off security. Off is currently the default
# 是否以安全認證方式運行,默認是不認證的非安全方式
#noauth = true

# developing drivers)用於開發驅動程序時的檢查客戶端接收數據的有效性
#objcheck = true
# Enable db quota management
# 啓用數據庫配額管理,默認每個db可以有8個文件,可以用quotaFiles參數設置
#quota = true
# 設置oplog記錄等級
# Set oplogging level where n is

# Replication Options 複製選項
# in replicated mongo databases, specifyhere whether this is a slave or master 在複製中,指定當前是從屬關係
#slave = true
#source = master.example.com
# Slave only: specify a single database toreplicate
#only = master.example.com
# or
