Changing the password in MongoDB for existing user
提问by Srivatsa N
I have production environment where my mongoDB is up and running and DBAs are asking us to change the password which we use for authentication. One way to do this is run the addUser command again with a new password as described in change password
我有生产环境，我的 mongoDB 已启动并运行，DBA 要求我们更改用于身份验证的密码。一种方法是使用更改密码中所述的新密码再次运行 addUser 命令
> db.auth("app_user", "somepassword")
db.addUser("app_user", "new password")
This is as good as a adding a new user.
这与添加新用户一样好。
I understand that I have to restart mongod with the --auth option once I add a new user as described inbut as this is a production env and I can't restart my server. Is there any other option ? or if my approach is wrong how to change the password in mongoDB

You linked to a question asking about adding authentication to MongoDB which involves starting 'mongod' with option --auth. Since you are already running with --auth the restart is not necessary in your scenario.
您链接到一个关于向 MongoDB 添加身份验证的问题，该问题涉及使用 --auth 选项启动“mongod”。由于您已经使用 --auth 运行，因此在您的场景中不需要重新启动。
Just change the user password and you'll be set to go.
只需更改用户密码，您就可以开始了。
