篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CentOs6.x安装mongodb3.4.x相关的知识,希望对你有一定的参考价值。

一、系统及安装说明

      系统:CentOS6.x_x64,mongodb-3.4.10。mongodb官方下载地址 https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.4.10.tgz。本次安装选择编辑yum安装。


二、配置官方yum库

1>创建yum安装库文件

#vim /etc/yum.repos.d/mongodb-org-3.4.repo    #创建之后可以直接使用yum安装
[mongodb-org-3.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

当设置gpgcheck=0时,gpgkey路径可以不设置


2>yum安装

#yum install -y mongodb-org
#当出现以下即为安装中
updates/primary_db                                                                                                                                                                                                                            | 5.3 MB     00:01

三、自定义安装配置

 1>安装成功后,数据和日志目录默认是在 /var/lib/mongo 和 /var/log/mongodb,为方便管理我们可进行自定义。以 /data/mongodb  为例

 

 2>编辑/etc/mongod.conf

#vim /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/data
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.


#security:

#operationProfiling:

#replication:

#sharding:

## Enterprise-Only Options

#auditLog:

#snmp

3>创建目录

#mkdir -p /data/mongodb/data
#mkdir -p /data/mongodb/log
#chown   mongod.mongod /data/mongodb -R   #修改权限,否则mongo有可能启动不了

四、启动并测试

1>启动mongod

#service mongod start|stop|restart

2>添加到开机启动项

#chkconfig --add mongod
#chkconfig mongod on

3>登录测试

#mongo --host 127.0.0.1

环境不通解决办法也不通,详情请参照官方文档 https://docs.mongodb.com/manual/tutorial/transparent-huge-pages/


2>创建脚本

# vim  /etc/init.d/disable-transparent-hugepages

#!/bin/bash### BEGIN INIT INFO
# Provides:          disable-transparent-hugepages
# Required-Start:    $local_fs
# Required-Stop:
# X-Start-Before:    mongod mongodb-mms-automation-agent
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Disable Linux transparent huge pages
# Description:       Disable Linux transparent huge pages, to improve
#                    database performance.
### END INIT INFO
case $1 in
  start)
    if [ -d /sys/kernel/mm/transparent_hugepage ]; then
      thp_path=/sys/kernel/mm/transparent_hugepage    elif [ -d /sys/kernel/mm/redhat_transparent_hugepage ]; then
      thp_path=/sys/kernel/mm/redhat_transparent_hugepage    else
      return 0
    fi

    echo 'never' > ${thp_path}/enabled    echo 'never' > ${thp_path}/defrag    re='^[0-1]+$'
    if [[ $(cat ${thp_path}/khugepaged/defrag) =~ $re ]]
    then
      # RHEL 7
      echo 0  > ${thp_path}/khugepaged/defrag    else
      # RHEL 6
      echo 'no' > ${thp_path}/khugepaged/defrag    fi

    unset re    unset thp_path    ;;
    esac

添加到开机服务

#chmod +x /etc/init.d/disable-transparent-hugepages
#chkconfig --add disable-transparent-hugepages


3>创建编辑 /etc/tune-profiles/no-thp/ktune.sh 

  #vim  /etc/tune-profiles/no-thp/ktune.sh 

#echo "set_transparent_hugepages never" > ktune.sh
#chmod +x ktune.sh
#tuned-adm profile no-thp 
#如果提示找不到命令请执行yum install tuned -y

 #vim /etc/security/limits.conf

添加

mongod soft nofile 64000
mongod hard nofile 64000
mongod soft nproc 32000
mongod hard nproc 32000

重启系统 sudo reboot
