一、安装

编辑/etc/yum.repos.d/mongodb-org-3.2.repo

[mongodb-org-3.2]

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=0
enabled=1

yum install -y mongodb-org

二、配置

编辑/etc/mongod.conf

# mongod.conf
# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data.
systemLog:destination: filelogAppend: truepath: /var/log/mongodb/mongod.log
# Where and how to store data.
storage:dbPath: /data/mongojournal:enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:
# how the process runs
processManagement:fork: true  # fork and run in backgroundpidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile

执行

echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

编辑/etc/rc.local，添加

echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

编辑vi /etc/security/limits.d/99-mongodb-nproc.conf

# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
*          soft    nproc     35000
root       soft    nproc     unlimited

三、防火墙

iptables -I INPUT 10 -s <允许ip> -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -A OUTPUT -d <允许ip> -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT
