redis error: 

redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

解决：

　　config set stop-writes-on-bgsave-error no ;    config set stop-writes-on-bgsave-error no

mongo启动、重启和关闭命令

1. sudo service mongod start
2. sudo service mongod restart
3. sudo service mongod stop

配置文件后台启动Mongodb
nohup sudo mongod --config /etc/mongodb.conf &

更改mongodb --path 后可以用一下命令解决 权限问题

sudo chown -Rh mongodb:mongodb /renpeng/mongodb*
sudo chown -R mongodb:mongodb /renpeng/mongodb/*
# chown [-R] [用户名称:组名称] [文件或目录]

-h或–no-dereference：只对符号链接的文件做修改，而不更改其他任何相关文件
