安装与管理MongoDB

1.安装解压源码包

[root@bogon ~]# tar xf mongodb-linux-x86_64-rhel70-4.0.6.tgz

[root@bogon ~]# mv mongodb-linux-x86_64-rhel70-4.0.6/ /usr/local/mongodb

2.指定一个进程同一时间最多可开启的文件数

[root@bogon ~]# ulimit -n

1024

[root@bogon ~]# ulimit -n 65535

[root@bogon ~]# ulimit -n

65535

3.用户最多可开启的程序数目

[root@bogon ~]# ulimit -u

11690

[root@bogon ~]# ulimit -u 65535

[root@bogon ~]# ulimit -u

65535

4.创建数据目录，日志文件及目录并创建相应的配置文件

[root@mongodb ~]# mkdir -p /data/mongodb1

[root@mongodb ~]# mkdir -p /data/logs/mongodb

[root@mongodb ~]# touch /data/logs/mongodb/mongodb1.log

[root@mongodb ~]# cd /usr/local/mongodb/

[root@mongodb mongodb]# ls

bin  LICENSE-Community.txt  MPL-2  README  THIRD-PARTY-NOTICES

[root@mongodb mongodb]# mkdir conf

[root@mongodb mongodb]# vim conf/mongodb1.conf

port=27017

dbpath=/data/mongodb1

logpath=/data/logs/mongodb/mongodb1.log

logappend=true

fork=true

maxConns=5000

storageEngine=mmapv1

5.启动MongoDB数据库，-f指定配置文件

[root@mongodb mongodb]# /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb1.conf

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

forked process: 2324

child process started successfully, parent exiting

[root@mongodb mongodb]# netstat -anpt |grep mongod

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      2324/mongod

6.设置开机自动启动

[root@mongodb mongodb]# vim /etc/rc.local

rm -f /data/mongodb1/mongod.lock

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb1.conf

7.连接数据库

[root@mongodb ~]# /usr/local/mongodb/bin/mongo

> show dbs

admin   0.078GB

config  0.078GB

local   0.078GB

> exit

bye

1. 开启服务与关闭服务

[root@mongodb~]#/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb1.conf --shutdown

killing process with pid: 2806

[root@mongodb ~]# netstat -anpt |grep mongod

[root@mongodb~]#/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb1.conf

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

forked process: 2885

child process started successfully, parent exiting

[root@mongodb ~]# netstat -anpt |grep mongod

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      2885/mongod   

1. 开启多个实例（两个）

[root@mongodb ~]# cd /usr/local/mongodb/

[root@mongodb mongodb]# cd conf/

[root@mongodb conf]# cp mongodb1.conf mongodb2.conf

[root@mongodb conf]# vim mongodb2.conf

[root@mongodb conf]# mkdir /data/mongodb2

[root@mongodb conf]# touch /data/logs/mongodb/mongodb2.log

[root@mongodb conf]# chmod 777 /data/logs/mongodb/mongodb2.log

1. 编写启动停止脚本管理多个实例

[root@mongodb ~]# cd /etc/init.d

[root@mongodb init.d]# vim mongodb

#!/bin/bash

INSTANCE=$1

ACTION=$2

case "$ACTION" in

‘start‘)

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/"$INSTANCE".conf;;

‘stop‘)

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/"$INSTANCE".conf --shutdown;;

‘restart‘)

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/"$INSTANCE".conf --shutdown

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/"$INSTANCE".conf;;

esac

[root@mongodb init.d]# chmod +x mongodb

[root@mongodb ~]# /etc/init.d/mongodb mongodb1 start

[root@mongodb ~]# /etc/init.d/mongodb mongodb2 start

[root@mongodb ~]# netstat -anpt |grep mongod

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      2885/mongod         

tcp        0      0 127.0.0.1:27018         0.0.0.0:*               LISTEN      3204/mongod
