mongodb3.2二进制单机版安装

Posted 2020-06-08

            mongodb3.2二进制安装

1.环境介绍

2.配置环境变量,修改与之相关的系统参数

3.创建mongodb运行用户和目录等

4.上传安装包，解压安装

5.创建配置文件

6.启动并进行简单测试

7.总结 

1.环境介绍：

OS:Centos6.5_64

MongoDB版本：mongodb-linux-x86_64-rhel62-v3.2-latest.tgz

Memory:2G

2.配置环境变量,修改与之相关的系统参数

在该文件中末尾添加这些参数,否则后面会有相应地告警信息

[[email protected] ~]# vim /etc/security/limits.conf

*  -  fsize        unlimited    # (file size)

*  -  cpu          unlimited    # (cpu time)

*  -  as           unlimited    # (virtual memory size)

*  -  nofile       64000        # (open files)

*  -  nproc        64000        # (processes/threads)

mongodb soft nofile 64000

mongodb hard nofile 64000

mongodb soft nproc 32000

mongodb hard nproc 32000

在proc中关闭NUMA

[[email protected] ~]# echo 0 > /proc/sys/vm/zone_reclaim_mode 

[[email protected] ~]# sysctl -w vm.zone_reclaim_mode=0

vm.zone_reclaim_mode = 0

[[email protected] ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled

[[email protected] ~]# echo never > /sys/kernel/mm/transparent_hugepage/defrag

[[email protected] local]# vim /etc/rc.local 

if test -f /sys/kernel/mm/transparent_hugepage/enabled; then

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

fi

if test -f /sys/kernel/mm/transparent_hugepage/defrag; then

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

fi

上述操作的目的是解决类似如下的告警信息：

2015-03-19T00:43:27.760+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is ‘always‘.

2015-03-19T00:43:27.760+0800 I CONTROL  [initandlisten] **        We suggest setting it to ‘never‘

3.创建mongodb运行用户和目录等

因为高版本的mongodb需要独立的用户来运行mongod进程，像mysqld需要mysql用户一样,

所以这里我推荐创建一个用户。如果不创建的话，也能运行，不过日志中会有相应的告警提示信息。

[[email protected] ~]# useradd mongodb  # 注意:mongodb这个用户名可以取别的

[[email protected] ~]# passwd mongodb

Changing password for user mongodb.

New password: 

BAD PASSWORD: it is based on a dictionary word

BAD PASSWORD: is too simple

Retype new password: 

passwd: all authentication tokens updated successfully.

[[email protected] ~]# 

创建需要的目录，并修改权限,切换到mongodb用户模式

[[email protected] ~]# su - mongodb

[[email protected] ~]$ mkdir -p {data,log,conf}

[[email protected] ~]$ ll

total 12

drwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 conf

drwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 data

drwxrwxr-x 2 mongodb mongodb 4096 Jan 25 14:03 log

[[email protected] ~]$ 

4.上传安装包，解压安装

[[email protected] ~]$ wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-rhel62-v3.2-latest.tgz

[[email protected] ~]$ ll

total 64900

drwxrwxr-x 2 mongodb mongodb     4096 Jan 25 14:03 conf

drwxrwxr-x 2 mongodb mongodb     4096 Jan 25 14:03 data

drwxrwxr-x 2 mongodb mongodb     4096 Jan 25 14:03 log

-rw-rw-r-- 1 mongodb mongodb 66443467 Jan 23 02:47 mongodb-linux-x86_64-rhel62-v3.2-latest.tgz

[[email protected] ~]$ tar -zxf mongodb-linux-x86_64-rhel62-v3.2-latest.tgz 

[[email protected] ~]$ mv mongodb-linux-x86_64-rhel62-3.2.1-83-g187028f/ mongodb3.2.1

[[email protected] ~]$ rm -f mongodb-linux-x86_64-rhel62-v3.2-latest.tgz  # 可以不用删除

5.创建配置文件

[[email protected] ~]$ vim /home/mongodb/.bash_profile 

export PATH=/home/mongodb/mongodb3.2.1/bin:$PATH

[[email protected] ~]$ source /home/mongodb/.bash_profile 

[[email protected] ~]$ vim conf/mongodb.conf

# bind_ip=192.168.0.100 # ip绑定

port=37000  # 端口号

dbpath=/home/mongodb/data/

logpath=/home/mongodb/log/mongodb.log # 输出日志文件名称

pidfilepath=/home/mongodb/mongobd.pid # pid文件名称

journal=true

maxConns=50000 # 最大连接数

logappend=true  # 日志输出方式

fork=true # 以守护进程的方式运行，创建服务器进程

# httpinterface=false # web界面

noauth=true 

cpu=true

[[email protected] ~]$ 

6.启动并进行简单测试

启动有两种方式启动，直接命令行启动，还有一种就是使用配置文件启动,

强烈建议使用配置文件启动。

[[email protected] ~]$ /home/mongodb/mongodb3.2.1/bin/mongod -f /home/mongodb/conf/mongodb.conf 

about to fork child process, waiting until server is ready for connections.

forked process: 32485

7. 关闭mongodb数据库

关闭mongodb数据库，这里有三种安全的方式

(1) kill -4 pid 

[[email protected] ~]$ ps -ef|grep ‘bin/mongod‘|grep -v ‘grep‘

mongodb  32485     1  0 14:43 ?        00:00:07 /home/mongodb/mongodb3.2.1/bin/mongod -f /home/mongodb/conf/mongodb.conf

[[email protected] ~]$ ps -ef|grep ‘bin/mongod‘|grep -v ‘grep‘|awk -F" " ‘{print $2}‘

32485

[[email protected] ~]$ kill -4 `ps -ef|grep ‘bin/mongod‘|grep -v ‘grep‘|awk -F" " ‘{print $2}‘`

日志太多,这里省略...

再次启动看看

从关闭和启动日志中看,相对使用kill -4 而言，使用kill -2 更安全些。

(3) 使用db.shutdownServer()关闭mongodb数据库

可见,使用db.shutdownServer()和使用kill -2 比较放心些。所以我们最好能采用这两种的其中一个即可。

7.总结 

  本文档是基于目前相对较新的版本在测试过境中搭建的过程,而且是单机环境。目的是从头开始尝试

mongodb这种NoSQL数据库的使用。个人看重的除了mongodb自身的优势外,最喜欢它的复制集和分片功能。

在这两点上,目前关系型数据库实现起来相对较复杂，不易维护管理。
