mongo数据库开启日志功能

查看当前配置：

mongo -u root -pCjxx-2023 --authenticationDatabase admin
#查看日志等级，默认为0不记录日志
db.getLogComponents()
# 在 Mongo Shell 中查看启动命令：
> db.adminCommand({getCmdLineOpts: 1})

配置后检查：

#宿主机：
ls -l /home/data/taiyuan/mongo-3-new/logs
#进入容器
ls -l /var/log/mongodb/*.log
tail -f /var/log/mongodb/mongod.log
mongo -u root -pCjxx-2023 --authenticationDatabase admin
db.adminCommand({getParameter: 1, logLevel: 1})
#应该输出：{ "logLevel" : 1, "ok" : 1 }
show dbs
show collections
​
#查询操作会在日志文件中输出，类似：
