mongodb集群安装

1.准备部署安装包

（将所有包放到/usr/local/page目录下，pape是自己命名创建的目录）

mongodb-linux-x86_64-3.4.3.tgz

2.安装开始

##一、每台机器执行这一段脚本

cd /usr/local/page

tar -zxvf mongodb-linux-x86_64-3.4.3.tgz

mv  mongodb-linux-x86_64-3.4.3 /usr/local/mongodb

mkdir -p /hxdata/mongodb/data

mkdir -p /hxdata/mongodb/log

##二、启动三台机器，不带密钥形式

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.191 \

--replSet=hxrs

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.192 \

--replSet=hxrs

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.193 \

--replSet=hxrs

##三、任选一台，进入控制台，进行创建用户，创建集群操作

/usr/local/mongodb/bin/mongo 192.168.1.191:12700

use admin

cfg={_id:"hxrs", members:[{_id:0, host:'192.168.1.191:12700'}, {_id:1, host:'192.168.1.192:12700'}, {_id:2, host:'192.168.1.193:12700', arbiterOnly:true}]}

rs.initiate(cfg)

rs.status()

use admin

db.createUser({user:"root",pwd:"123456",roles:["root"]})

db.auth("root","123456")

exit

##四、任选一台机器生产密钥，copy到其它机器对应目录上

openssl rand -base64 741 > /usr/local/mongodb/bin/mongo-keyfile

##五、启动三台机器，带密钥形式

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.1.191 \

--replSet=hxrs \

--auth --keyFile=/usr/local/mongodb/bin/mongo-keyfile

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.1.192 \

--replSet=hxrs \

--auth --keyFile=/usr/local/mongodb/bin/mongo-keyfile

/usr/local/mongodb/bin/mongod \

--dbpath=/hxdata/mongodb/data \

--logpath=/hxdata/mongodb/log/server.log \

--logappend \

--fork \

--port=12700 \

--bind_ip=192.168.1.193 \

--replSet=hxrs \

--auth --keyFile=/usr/local/mongodb/bin/mongo-keyfile

##四、任选一台，进入控制台，创建专门的库

/usr/local/mongodb/bin/mongo 192.168.1.191:12700

use admin

db.auth("root","10jqka")

use dbtest

db.test.insert({_id:1,name:"test"})

db.createUser({user:"chen",pwd:"123456",roles:["dbOwner"]})

db.auth("chen","123456")

###备份脚本

/usr/local/mongodb/bin/mongodump -h 127.0.0.1:12701 -u chen -p 123456  -d dbtest -o /root/mongobak

###还原脚本

/usr/local/mongodb/bin/mongorestore -h 192.168.1.191:12700 -u chen -p 123456  -d dbtest --dir /root/mongobak/dbtest
