大數據分佈式內存

一．創建目錄
1．mkdir -p /home/mongodb/data/master
2．mkdir -p /home/mongodb/data/slaver
3．mkdir -p /home/mongodb/data/arbiter

二．配置文件
1.創建master.conf文件
#master.conf
dbpath=/home/mongodb/data/master
logpath=/home/mongodb/log/master.log
pidfilepath=/home/mongodb/master.pid
directoryperdb=true
logappend=true
replSet=testrs
bind_ip=192.168.1.4
port=27017
oplogSize=10000
fork=true
noprealloc=true

2.創建arbiter.conf文件
#arbiter.conf
dbpath=/home/mongodb/data/arbiter
logpath=/home/mongodb/log/arbiter.log
pidfilepath=/home/mongodb/arbiter.pid
directoryperdb=true
logappend=true
replSet=testrs
bind_ip=192.168.1.12
port=27017
oplogSize=10000
fork=true
noprealloc=true

3.創建slaver.conf文件
#slaver.conf
dbpath=/home/mongodb/data/slaver
logpath=/home/mongodb/log/slaver.log
pidfilepath=/home/mongodb/slaver.pid
directoryperdb=true
logappend=true
replSet=testrs
bind_ip=192.168.1.11
port=27017
oplogSize=10000
fork=true
noprealloc=true

三．啓動命令

1. cd /home/mongodb/bin
2. ./mongod -f /home/mongodb/master.conf
3. ./mongod --fork --dbpath /home/mongodb/db --logpath /home/mongodb/log/set1.log --replSet test
4. ./mongod --fork --dbpath /home/mongodb/db --logpath /home/mongodb/log/set1.log --replSet test
5. ./mongod --fork --dbpath /home/mongodb/db --logpath /home/mongodb/log/set1.log --replSet test
6. ./mongo 192.168.1.4:27017
   四.實戰
   1.工程配置
   
   2.部分核心代碼
