MongoDB Environment Deployment

Deployment steps:
1. Download the installation package Https://www.mongodb.org/dl/linux
I chose it.

　　

2. TAR-XZVF linux/mongodb-linux-x86_64-latest.tgz

3. Renaming
MV Mongodb-linux-x86_64-4.1.0-266-gc7451c0e11 MongoDB

4. Create a folder (in the MongoDB directory)
mkdir data
mkdir Log
mkdir etc
Such as:

Create a mongodb.conf file under the ETC directory
Vim mongodb.conf
Put the following configuration in the same manner:

dbpath=/usr/local/fb4/mongodb/data/# (Data directory, which changes according to its actual path)
logpath=/usr/local/fb4/mongodb/log/mongodb.log# (log directory, which changes according to its actual path)
Logappend = True
port=27017
Fork=true

5. Start MongoDB
./mongod--config/usr/local/fb4/mongodb/etc/mongodb.conf

------------------------------------------Problem Set-----------------
Question one:

Path problem: So the Conf configuration file must be configured correctly first check the following configuration file:
dbpath=/usr/local/fb4/mongodb/data/# (at first the data is not added "/")
Logpath=/usr/local/fb4/mongodb/log/mongodb.log
Logappend = True
port=27017
Fork=true

Workaround:
1. Delete mongo.lock files
RM-RF Mongod.lock

2,/usr/local/fb4/mongodb/bin/mongod--repair--dbpath=/usr/local/fb4/mongodb/data

./mongod--config/usr/local/fb4/mongodb/etc/mongodb.conf

Question two:

[Email protected] bin]#./mongo
MongoDB Shell version V4.1.0-266-gc7451c0e11
Connecting to:mongodb://127.0.0.1:27017
2018-06-11t14:44:16.435+0800 E QUERY [js] error:couldn ' t connect to server 127.0.0.1:27017, connection attempt failed:so Cketexception:error Connecting to 127.0.0.1:27017:: Caused by:: Connection refused:
[Email protected]/mongo/shell/mongo.js:251:13
@ (Connect): 1:6
Exception:connect failed

MongoDB state: Client failed to start
Workaround:
1, if the database appears as above can not connect the reason, may be the data directory Mongod.lock file problem, can be repaired with the following command:
[Plain] View plain copy
1. [Email protected] mongodb]#/bin/mongod--repair

or delete Mongod.lock directly
[Plain] View plain copy
1. Rm-f/usr/local/mongodb/data/db/mongod.lock

Then start MongoDB again.

2, if the first step can not be solved, then is the path setting problem, by re-set the path to solve the problem
[Plain] View plain copy
1. [Email protected] mongodb]#/bin/mongod--dbpath=/usr/local/mongodb/data/db/

Success:
