MongoDB 主從
系統：Centos6.6x64
安裝目錄：/usr/local/
主：172.16.15.101
從：172.16.15.102
1,下載安裝：
# 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環境變量配置
# cat /etc/profile
# export PATH=$PATH:/usr/local/mongodb/bin
# source /etc/profile
3,iptables/selinux及內核設置：
# 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,創建文件存放目錄：
# mkdir -p /usr/local/mongodb/{log,db,conf}
主服務 ：172.16.15.101
5,mongod.conf 參考配置；

6, mongod.conf 參考配置；

7,從服務器啓動
/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,啓動檢測mongod進程以及端口
# 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 日誌 進程端口啓動就好；
主的啓動：
/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 自控腳本
# useradd -s /sbin/nologin -r mongod
# chown -R mongod: /usr/local/mongodb
# /etc/init.d/mongod
// * 這個附件有官方配置信息
# chmod +x /etc/init.d/mongod
// * 需要更改配置目錄
# 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
