mongodb - 64位系统，插入报错

仲颖凯翰奕颖发布于 2022-10-25 04:01

，经过编译生成的mongodb，文件超过2GB提示错误

rs0:PRIMARY> db.Data.insert({"name":"test"})
WriteResult({
        "nInserted" : 0,
        "writeError" : {
                "code" : 10085,
                "errmsg" : "insertDocument :: caused by :: 10085 can't map file memory"
        }
})

根据官方文档，目前调整了系统参数：
上面安装了redis
MEM 32GB，

vi /etc/sysctl.conf

vm.overcommit_memory = 1
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1

vi /etc/profile

ulimit -f unlimited
ulimit -t unlimited
ulimit -v unlimited
ulimit -n 64000
ulimit -m unlimited
ulimit -u 64000

source /etc/profile

ulimit -a

core file size (blocks, -c) 1

重启了数据库，插入暂时恢复正常
