MongoDB 主从
系统：Centos6.6×64
安装目录：/usr/local/
主：172.16.15.101
从：172.16.15.102
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 <<HERE
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
