我可以如何知道我的 MongoDB 数据库是 64 位的?
你可以配合使用 buidInfo 和 runCommand 来检测 32 位或 64 位的 MongoDB。首先将数据库切换到 admin。以下是语法:
use admin
之后使用以下语法来了解服务器是否运行 64 位 MongoDB:
db.runCommand(buildInfo)
现在,执行上述语法。
> use admin switched to db admin > db.runCommand("buildInfo");
以下是显示 MongoDB 是 64 位的输出:
{ "version" : "4.0.5", "gitVersion" : "3739429dd92b92d1b0ab120911a23d50bf03c412", "targetMinOS" : "Windows 7/Windows Server 2008 R2", "modules" : [ ], "allocator" : "tcmalloc", "javascriptEngine" : "mozjs", "sysInfo" : "deprecated", "versionArray" : [ 4, 0, 5, 0 ], "openssl" : { "running" : "Windows SChannel" }, "buildEnvironment" : { "distmod" : "2008plus-ssl", "distarch" : "x86_64", "cc" : "cl: Microsoft (R) C/C++ Optimizing Compiler Version 19.00.24223 for x64", "ccflags" : "/nologo /EHsc /W3 /wd4355 /wd4800 /wd4267 /wd4244 /wd4290 /wd4068 /wd4351 /wd4373 /we4013 /we4099 /we4930 /WX /errorReport:none /MD /O2 /Oy- /bigobj /utf-8 /Zc:rvalueCast /Zc:strictStrings /volatile:iso /Gw /Gy /Zc:inline", "cxx" : "cl: Microsoft (R) C/C++ Optimizing Compiler Version 19.00.24223 for x64", "cxxflags" : "/TP", "linkflags" : "/nologo /DEBUG /INCREMENTAL:NO /LARGEADDRESSAWARE /OPT:REF", "target_arch" : "x86_64", "target_os" : "windows" }, "bits" : 64, "debug" : false, "maxBsonObjectSize" : 16777216, "storageEngines" : [ "devnull", "ephemeralForTest", "mmapv1", "wiredTiger" ], "ok" : 1 }
