conf文件：
dbpath = /usr/local/mongodb/db logpath = /usr/local/mongodb/logs/mongodb.log port = 27017 fork = true logappend = true pidfilepath = /usr/local/mongodb/mongo.pid #nohttpinterface = true shardsvr = true #directoryperdb = true #auth = true rest = true
唯一不同是自启动文件：
#!/bin/sh # chkconfig: - 64 36 # description:mongod case $1 in start) /usr/local/kencery/mongoDB/mongodb/bin/mongod --maxConns 20000 --config /usr/local/kencery/mongoDB/mongodb/bin/mongodb.conf ;; stop) /usr/local/kencery/mongoDB/mongodb/bin/mongo 127.0.0.1:27017/admin --eval "db.shutdownServer()" ;; status) /usr/local/kencery/mongoDB/mongodb/bin/mongo 127.0.0.1:27017/admin --eval "db.stats()" ;; esac
