进入到mongo的命令行交互程序，输入：

use admin
db.auth('root', '密码')
db.runCommand({logRotate: 1})

输出

spy:PRIMARY> db.runCommand({logRotate: 1})
{
    "ok" : 1,    # 1表示成功
    "$clusterTime" : {
        "clusterTime" : Timestamp(1639454694, 22),
        "signature" : {
            "hash" : BinData(0,"cSlu4Fz/b6GilocR/VwfXOWdsxM="),
            "keyId" : NumberLong("7031832375268999172")
        }
    },
    "operationTime" : Timestamp(1639454694, 22)
