Mongodb 3.2.8: 集群环境搭建

简介

MongoDB是一种面向文档的数据库管理系统，由C++撰写而成，以此来解决应用程序开发社区中的大量现实问题。2007年10月，MongoDB由10gen团队所发展。2009年2月首度推出。

##mongodb集群部署步骤:

#全局配置

mkdir -pv /data/soft

cd /data/soft/

wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.2.8.tgz

tar -xf mongodb-linux-x86_64-rhel70-3.2.8.tgz -C /usr/local/

cd /usr/local/

ln -sv mongodb-linux-x86_64-rhel70-3.2.8/ mongodb

mkdir -p /usr/local/mongodb/data

cat >> /etc/profile << "EOF"

export PATH=$PATH::/usr/local/mongodb/bin

EOF

source /etc/profile

mkdir -p /usr/local/mongodb/{master,arbiter,slave}/data
