1.1 运行命令

# cd /home/wlj
# wget http://downloads.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.2.12.tgz?_ga=1.28205556.912007513.1487138979
# tar -zxvf mongodb-linux-x86_64-rhel70-3.2.12.gz
# mv mongodb-linux-x86_64-rhel70-3.2.12 mongodb
# mkdir mongodb/conf
# vim mongodb/conf/mongo.config

1.2 配置文件

dbpath=/data/mongodb/data/db
logpath=/data/mongodb/logs/mongodb.log
port=27017
fork=true #后台执行
logappend=true
wiredTigerCacheSizeGB=10 #设置进程的堆内存

# mkdir -p /data/mongodb/data/db
# mkdir -p /data/mongodb/logs/

1.4 配置 MongoDB 家目录和 PATH 环境变量

# vim /etc/profile.d/mongodb.sh

export MONGODB_HOME=/home/jj/mongodb
export PATH=$MONGODB_HOME/bin:$PATH

# source /etc/profile.d/mongodb.sh    
# mongod -f /home/wlj/mongodb/conf/mongo.config
# mongo

2. 复制集

2.1 安装 numactl

# yum install numactl

2.2 修改系统变量

# echo 1 > /proc/sys/vm/overcommit_memory  
# echo never >> /sys/kernel/mm/transparent_hugepage/enabled 
# echo never >> /sys/kernel/mm/transparent_hugepage/defrag 
# 设置最大文件数
# ulimit -u 32767

2.3 Master 配置文件

dbpath=/data/volume_b/mongodb/data/db
logpath=/data/volume_b/mongodb/logs/mongodb.log
pidfilepath=/data/volume_b/mongodb/logs/mongod.pid
port=27017
#后台启动
fork=true 
logappend=true
journal=true
# 复制集名称
replSet=fbj
wiredTigerCacheSizeGB=10 #设置进程的堆内存

2.4 Master 启动

numactl --interleave=all ./bin/mongod -config /home/wlj/conf/mongod.conf

2.5 复制集配置（两台）

dbpath=/data/volume_b/mongodb/data/db
logpath=/data/volume_b/mongodb/logs/mongodb.log
pidfilepath = /data/volume_b/mongodb/logs/mongod.pid
port=27017
fork=true
logappend=true
journal=true
# 复制集名称
replSet=fbj
wiredTigerCacheSizeGB=10 #设置进程的堆内存

2.6 复制集启动（两台）

# numactl --interleave=all ./bin/mongod -config ./conf/mongod.conf

2.7 登录 Master
