脚本宝典收集整理的这篇文章主要介绍了cgroup限制mongodb进程内存大小，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
以限制mongodb的内存大小为例。
mkdir /cgroup/memory/test/ echo 50M > /cgroup/memory/test/memory.limIT_in_bytes echo 50M > /cgroup/memory/test/memory.memsw.limit_in_bytes cgexec -g memory:test mongod -port 27017 --bind_ip 127.0.0.1 --dbpath /VAR/lib/mongo
通过cgroup限制后，当内存达到限额，进程会被kill。
[root@centos mongo]# cgexec -g memory:test mongod -port 27017 --bind_ip 127.0.0.1 --dbpath /var/lib/mongo 2014-07-18T23:20:53.228+0800 [initandlisten] MongoDB starting : pid=2529 port=27017 dbpath=/var/lib/mongo 64-bit host=centos 2014-07-18T23:20:53.228+0800 [initandlisten] db version v2.6.3 2014-07-18T23:20:53.228+0800 [initandlisten] git version: 255f67a66f9603c59380b2a389e386910bbb52cb 2014-07-18T23:20:53.228+0800 [initandlisten] build info: Linux build12.nj1.10gen.cc 2.6.32-431.3.1.el6.x86_64 #1 SMP Fri Jan 3 21:39:27 UTC 2014 x86_64 BOOST_LIB_VERSION=1_49 2014-07-18T23:20:53.228+0800 [initandlisten] allocator: tcmalloc 2014-07-18T23:20:53.228+0800 [initandlisten] options: { net: { bindIp: "127.0.0.1", port: 27017 }, storage: { dbPath: "/var/lib/mongo" } } 2014-07-18T23:20:53.304+0800 [initandlisten] journal dir=/var/lib/mongo/journal 2014-07-18T23:20:53.304+0800 [initandlisten] recover : no journal files PResent, no recovery needed 2014-07-18T23:20:53.374+0800 [initandlisten] waiting for connections on port 27017 2014-07-18T23:20:57.838+0800 [initandlisten] connection accepted From 127.0.0.1:36712 #1 (1 connection now oPEn) 2014-07-18T23:21:15.077+0800 [initandlisten] connection accepted from 127.0.0.1:36713 #2 (2 connections now open) 2014-07-18T23:21:52.342+0800 [conn2] getmore test.my_collection cursorid:34538199491 ntoreturn:0 keyUpdates:0 numYields:39 locks(micros) r:121572 nreturned:95052 reslen:4194299 202ms 2014-07-18T23:21:53.376+0800 [clientcursormon] mem (MB) res:136 virt:12809 2014-07-18T23:21:53.376+0800 [clientcursormon] mapped (incl journal view):12508 2014-07-18T23:21:53.376+0800 [clientcursormon] connections:2 2014-07-18T23:21:56.790+0800 [conn2] getmore test.my_collection cursorid:34538199491 ntoreturn:0 keyUpdates:0 numYields:88 locks(micros) r:142113 nreturned:95595 reslen:4194301 244ms Killed
数据查询脚本：
[root@centos data]# cat mongotestList.py
import pymongo
import time
client = pymongo.MongoClient("localhost", 27017)
db = client.test
print db.name
print db.my_collection
for item in db.my_collection.find():
print item
数据插入脚本：
[root@centos data]# cat mongotest2.py import pymongo import time client = pymongo.MongoClient("localhost", 27017) db = client.test print db.name print db.my_collection while True: db.my_collection.save({time.ctime(): time.time()})
