Limits mongodb memory usage in linux

Linux limits mongodb memory usage for multiple instances: You can bind a cpu to prevent mutual interference between multiple instances. The memory of www.2cto.com mongodb can also be restricted to the master to prevent all memory occupied by one instance. # Tudou@ B2C .xiaomi.com [plain] ulimit-s 4096 & ulimit-m 31457280 & sudo-u mongodb numactl -- cpunodebind = 0 -- localalloc/opt/soft/mongodb-2.2.0/bin/mongod -- fork -- master -- oplogSize 10240 -- port 27001 -- dbpath

Numactl -- cpunodebind = 0 bind the process to the first cpu. In this way, the cpu memory is free of interference. Source: http://blog.csdn.net/ylqmf/article/details/8099521
