Linux Centos7 server MongoDB installation, startup, remote management

Author: Songbao writes code

When you are young, you need to deal with it, because you are always debugging MongoDB locally and want to deploy it to the server for remote login management. This is a bit of a mess with MongoDB’s database. Following is a detailed tutorial on installing, starting, and remotely managing MongoDB on Linux Centos7 server.

One, foreword

Linux Centos7 server MongoDB installation, startup, remote management and other functions. Let’s use the yum setup package this time.

Check the Centos version of the server

cat /etc/os-release
Copy the code

The output

NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0; 31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"Copy the code

The Centos version is 7

Install Mongodb

Configure the source of system YUM

1. Create a. Repo file to generate the mongodb source

Vi/etc/yum. Repos. D/mongo - org - 4.2. RepoCopy the code

2. Add the configuration information

[mongo - org - 4.4] name = directing a Repository baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/ gpgcheck = 1 enabled = 1 gpgkey=https://www.mongodb.org/static/pgp/server-4.4.ascCopy the code
  • Name: Refers to the name
  • Baseurl: Get the download path
  • Gpgcheck: verifies RPM packages downloaded from this source
  • Enabled: Enables the source
  • Gpgkey: INDICATES GPG authentication

3. Save the Settings and exit

:wq
Copy the code

Install Mongodb using yum

1, install,

sudo yum install -y mongodb-org
Copy the code

3. Start the service

Starting the MongoDB Service

systemctl start mongod.service
Copy the code

The default MongoDB port is 27017. Check whether the MongoDB port is enabled

netstat -natp | grep 27017
Copy the code

Check whether the database is installed successfully

Ps - aux | grep mongod # to check the database process existsCopy the code

Implementation process

[rZ ~] # systemctl start mongod. Service/rZ ~ # netstat natp | grep TCP 27017 0 0 127.0.0.1:27017 0.0.0.0: * LISTEN 21255 / mongod/rZ ~ # ps - aux | grep mongod mongod 21255 1552004 65052 3.3 3.4?

5. List of common commands

MongoDB sudo chkconfig mongod on // 1, MongoDB sudo chkconfig mongod on // run the following command to restart the MongoDB service: // run the following command to restart the MongoDB service $(RPM - qa | grep mongo - org) # uninstall mongo sudo rm - r/var/log/mongo sudo rm # delete log files - r/var/lib/mongo # delete data fileCopy the code

4. Remotely connect to Mongodb

1. Modify the mongodb

vi /etc/mongod.conf
Copy the code
# network interfaces net: port: 27017 bindIp: 0.0.0.0 # Enter 0.0.0.0,: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.Copy the code

Change the binding IP address 127.0.0.1 by default, only local connections are allowed. Therefore, change the binding IP address to bindIp:0.0.0.0 and exit

2. Restart the mongodb service

sudo service mongod restart 
Copy the code

3. Open external ports

iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 27017 -j ACCEPT
Copy the code

4. Security port of Ali Cloud server

PS: In fact, after this is opened, we need to open the security port on ali Cloud server, so that we can really access the external world and configure the security group rules.
