1,下载安装：

# wget https://fastdl.mongodb.org/src/mongodb-src-r3.2.7.tar.gz?_ga=1.217384598.1880361485.1476164670

新版本  # wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.9.tgz

# tar -xf mongodb-linux-x86_64-3.2.7.tgz

# mv mmongodb-linux-x86_64-3.2.7 /usr/local/mongodb

2,mongodb环境变量配置

# cat /etc/profile

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

# source /etc/profile

3,iptables/selinux及内核设置：

# cat /etc/sysconfig/iptables 

-A INPUT -p tcp -m state --state NEW -m tcp --dport 28017 -j ACCEPT

-A INPUT -p tcp -m state --state NEW -m tcp --dport 27017 -j ACCEPT

# sed "s/SELINUX=enables/SELINUX=disabled/g" /etc/sysconfig/selinux

SELINUX=disabled

# cat >>/etc/rc.d/rc.local <

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

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

HERE

4,创建文件存放目录：

# mkdir -p /usr/local/mongodb/{log,db,conf}

主服务 ：172.16.15.101 

5,mongod.conf 参考配置；

6, mongod.conf 参考配置；

7,从服务器启动

/usr/local/mongodb/bin/mongod --fork --slave --source 172.16.15.101:27017 --port 27017 --dbpath /usr/local/mongodb/db --logpath /usr/local/mongodb/log/mongodb.log 

8,启动检测mongod进程以及端口

# mongod --fork --httpinterface --rest --jsonp --setParameter enableLocalhostAuthBypass=0 --pidfilepath /usr/local/mongodb/mongod.pid --dbpath /usr/local/mongodb/db --logpath /usr/local/mongodb/log/mongod.log  --logappend --logRotate rename --timeStampFormat ctime

主要的配置文件 日志 进程端口启动就好；

主的启动：

/usr/local/mongodb/bin/mongod --fork --master --oplogSize=1024 --port 27017 --dbpath /usr/local/mongodb/db --logpath /usr/local/mongodb/log/mongodb.log 

# ps -ef|grep mongod

# netstat -tunlp|grep mongod

9,init.d/mongod 自控脚本

# useradd -s /sbin/nologin -r mongod

# chown -R mongod: /usr/local/mongodb

# /etc/init.d/mongod

   // * 这个附件有官方配置信息

# chmod +x /etc/init.d/mongod

   // * 需要更改配置目录

# sed -i '/CONFIGFILE=/i MONGOD="/usr/local/mongodb/bin/mongod"' /etc/init.d/mongod

# sed -i '/CONFIGFILE=/s:/etc/mongod.conf:/usr/local/mongodb/conf/mongod.conf:g'  /etc/init.d/mongod
