Installing Mongodb on Fedora30 and above

• Due to licensing changes, Fedora no longer ships mongodb in 30 and above.

• These steps will also setup the mongodb-tools (mongodump, mongorestore etc).

  • Download MongoDB Binaries
  • Extract and Setup MongoDB Binaries
  • Create MongoDB Service User
  • Setup and Enable MongoDB System Service

Download MongoDB Binaries

• Download the appropriate binaries from MongoDB sources
• For Fedora30+ we will choose from the 4.x series: 'server' and 'Linux 64-bit Legacy x64'

Extract and Setup MongoDB Binaries

• The below commands will assume the current version is 4.0.12

curl https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-4.0.12.tgz -o /tmp/mongodb-linux-x86_64-4.0.12.tgz

tar -xvf /tmp/mongodb-linux-x86_64-4.0.12.tgz -C /tmp/

• Now copy the binaries into a proper $PATH

• If you just want the mongodump and mongorestore tools

cp /tmp/mongodb-linux-x86_64-4.0.12/bin/{mongodump,mongorestore,mongoreplay,bsondump} /usr/bin/

• If you are installing mongodb-server and everything else

cp /tmp/mongodb-linux-x86_64-4.0.12/bin/* /usr/bin/

Create Mongodb Service User

• We want to run mongodb as an unprivileged service user
• We're also going to set the home directory to /var/lib/mongodb
• This will give the mongodb group a gid of 992 and mongodb user a uid of 184

useradd -m -d /var/lib/mongodb -c "MongoDB Database Server" -u 184 -g 992 -s /sbin/nologin mongodb

Setup and Enable MongoDB System Service

• Now you'll want to install a systemd unit for Mongo and drop in generic configs.

cat > /etc/sysconfig/mongod <<EOF
OPTIONS="-f /etc/mongod.conf"

   - Mongod options file

# To run numactl before starting mongodb server
# https://docs.mongodb.com/manual/administration/production-notes/#configuring-numa-on-linux
#NUMACTL="/usr/bin/numactl --interleave=all"

EOF

• Mongd.conf

cat > /etc/mongod.conf <<EOF
systemLog:
  verbosity: 0
  destination: file
  path: /var/log/mongodb/mongod.log
  logAppend: true
  logRotate: reopen

  fork: true
  pidFilePath: /var/run/mongodb/mongod.pid

net:

  unixDomainSocket:

    pathPrefix: /var/run/mongodb

storage:
  dbPath: /var/lib/mongodb
  engine: wiredTiger

processManagement:
  fork: true
  pidFilePath: /var/run/mongodb/mongod.pid

  unixDomainSocket:
    enabled: true
    pathPrefix: /var/run/mongodb

storage:
  dbPath: /var/lib/mongodb
  engine: wiredTiger

EOF

• Now setup and install your systemd unit file

cat > /usr/lib/systemd/system/mongod.service <<EOF

• Enable and start the service

systemctl enable mongod
