重新启动MongoDB时出现此错误,我正在使用Mongo 3.2.4并在新计算机上进行此设置

Starting mongod... about to fork child process, waiting until server is ready for connections.

最佳答案 通过在/etc/security/limits.conf中插入以下行来解决此问题：

mongodb      soft    nofile          65535
mongodb      hard    nofile          90000
mongodb      soft    nproc           65535
mongodb      hard    nproc           90000

我们需要添加用于运行Mongo服务的用户帐户.通常,它是mongodb用户.
