nosql - 如何使用bash脚本安全关闭mongodb服务的进程？

Question

我直接kill掉mongodb的服务进程，下一次启动的时候就会出现unclean shutdown的提示。
我知道进入mongo程序进入mongo自己的shell可以关闭服务，不过如果我要使用bash将如何实现呢？
我知道mongo有一个--eval参数，可以直接运行命令，但如果我直接--eval "db.shutdownServer()"的话老是出现让我use admin的提示，但是如果我--eval "use admin;db.shutdownServer()"的话呢又说我语法错误，真不知道要怎么弄才能对

Answer 1

I found the answer to this question myself:

./mongo admin --eval "shutdownServer()"

That’s it. Of course, if you have a port or password, please add the corresponding parameters. The format can be seen in ./mongo --help
The reason why I have been asking this question before is because --help says that adding a username requires -u username, which is similar to mysql, but I have tried it

-u admin --eval "db.shutdownServer()"

Still not working, I don’t know if it’s a bug

Answer 2

Please try to use the kill -2 command to close the corresponding mongod process

Answer 3

./mongo ip:port/admin --eval "db.shutdownServer()"

Answer 4

mongo -u zhangsan -p 123456  127.0.0.1:27277/admin --eval "db.shutdownServer()"
使用这个命令,配合supervisor简直是爽到爆
