1.安装MongoDB

mongoDB的tar包下载地址：https://www.mongodb.com/download-center#atlas

解压安装包 tar -zxvf xxxxxxxxxx.tar

移动到安装目录 mv mongodb-linux-x86_64-xxx /usr/local/mongodb

添加环境变量 echo "export PATH=\$PATH:/usr/local/mongodb/bin【解压后移动过去会存在一个目录，所以需要配置】" > /etc/profile.d/mongodb.sh （这个里面要小心了！）

使环境变量生效 source /etc/profile.d/mongodb.sh

创建Mongodb用户和组 useradd -r -M -s /sbin/nologin mongod

***创建启动数据库和启动日志 mkdir -p /data/mongodb/{db,log}/

修改权限 chown -R mongod:mongod/data/mongodb/

配置mongoDB配置文件： vi /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: file

logAppend: true

path: /data/mongodb/log/mongod.log

#Where and how to store data.

storage:

dbPath: /data/mongodb/db

journal:

enabled: true

# engine:

# mmapv1:

# wiredTiger:

#how the process runs

processManagement:

fork: true # fork and run inbackground

pidFilePath: /var/run/mongodb/mongod.pid # location of pidfile

#network interfaces

net:

port: 27017

bindIp: 127.0.0.1 # Listen tolocal interface only, comment to listen on all interfaces.

#security:

#operationProfiling:

#replication:

#sharding:

## Enterprise-Only Options

#auditLog:

#snmp:

备注：

如果MongoDB端口不在27017-27019,28017-28019之间，需要执行以下步骤：

# yum -y install policycoreutils-python

# semanage port -a -t mongod_port_t -p tcp<port_number> 27017

创建MongoDB自启动脚本 vi /etc/init.d/mongod

#!/bin/bash

#mongod - Startup script for mongod

#chkconfig: 35 85 15

#description: Mongo is a scalable, document-oriented database.

#processname: mongod

#config: /etc/mongod.conf

#pidfile: /var/run/mongodb/mongod.pid

./etc/rc.d/init.d/functions

#things from mongod.conf get there by mongod reading it

#NOTE: if you change any OPTIONS here, you get what you pay for:

#this script assumes all options are in the config file.

CONFIGFILE="/etc/mongod.conf"

SYSCONFIG="/etc/sysconfig/mongod"

mongod=${MONGOD-/usr/local/mongodb/bin/mongod}

MONGO_USER=mongod

MONGO_GROUP=mongod

if [ -f "$SYSCONFIG" ]; then

. "$SYSCONFIG"

PIDDIR=`dirname $PIDFILEPATH`

#Handle NUMA access to CPUs (SERVER-3574)

#This verifies the existence of numactl as well as testing that the commandworks

NUMACTL_ARGS="--interleave=all"

if which numactl >/dev/null 2>/dev/null && numactl$NUMACTL_ARGS ls / >/dev/null 2>/dev/null

then

NUMACTL="numactl $NUMACTL_ARGS"

else

NUMACTL=""

start()

{

# Make sure the default pidfile directory exists

if [ ! -d $PIDDIR ]; then

echo -n $"Starting mongod: "

RETVAL=$?

echo

[ $RETVAL -eq 0 ] && touch /var/lock/subsys/mongod

}

restart () {

stop

start

}

#Send TERM signal to process and wait up to 300 seconds for process to go away.

#If process is still alive after 300 seconds, send KILL signal.

#Built-in killproc() (found in /etc/init.d/functions) is on certain versions ofLinux

#where it sleeps for the full $delay seconds if process does not respond fastenough to

#the initial TERM signal.

mongo_killproc()

{

local pid_file=$1

local procname=$2

local -i delay=300

local -i duration=10

local pid=`pidofproc -p "${pid_file}" ${procname}`

kill -TERM $pid >/dev/null 2>&1

usleep 100000

esac

exit $RETVAL

设置MongoDB服务开机自启动

chmod +x /etc/init.d/mongod

chkconfig mongod on

启动MongoDB服务

service mongod start

如果启动不成功：

主要查看启动脚本 .sh 文件中的配置的环境变量是否正确，同时查看db log的权限是否是脚本中配置的用户和组，同时可执行，我给的777

验证启动成功：

service mongod status
