mongodb:增加mongodb中的最大连接数

问题描述

我需要您的帮助来解决此问题

i need your help in solving this

这是我的ulimit -a在我的linux服务器上的结果

this is the result of my ulimit -a on my linux server

   core file size          (blocks, -c) 0
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 10000
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 24576
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

现在这是我的MongoDB的结果

Right now this is the result of my MongoDB

db.serverStatus().connections

{ "current" : 4, "available" : 5996 }

我想将MongoDb连接更多地增加到10000个.

I want to increase the MongoDb connections more to 10000 .

我尝试了不同的选项，例如在mongod1.conf中

I have tried different options like in my mongod1.conf

fork    = true
port    = 27017
maxConns = 10000

以及启动mongodb时的这一点

and also this while starting mongodb

mongod ulimit -n 10000  --config mongod1.conf

但是没有任何效果并且全部失败，请提前告知我如何将连接增加到10000个.

but nothing worked and all failed , please let me know how can i increase the connections to 10000 in my case , thanks in advance .

推荐答案

您还需要提高Linux内核允许的文件描述符数量和每个进程的文件描述符数量.

You also need bump up the number of file descriptors and number of file descriptors per process that the Linux kernel allows.

在Linux中，应通过在/proc/sys/fs/file-max或sysctl实用程序中编辑文件来进行配置.

In Linux, this should be configured by editing the file at /proc/sys/fs/file-max or by the sysctl utility.

• 编辑/etc/sysctl.conf文件并添加fs.file-max = 50000.这将设置可以作为系统范围限制运行的最大文件描述符.
• 运行ulimit -n 50000为打开的文件描述符的最大数量设置用户范围的限制.

• Edit the /etc/sysctl.conf file and add fs.file-max = 50000. This sets the maximum file descriptors that can run as a system-wide limit.
• Running ulimit -n 50000 sets the user-wide limit for the maximum number of file descriptors open.
