前提是安装好操作系统（本案例基于rhel6.10），数据库使用的存储可使用（xfs）
一、针对集群的每个节点，都需要创建用户和安装软件的基本操作：
--创建用户和路径
root/root123
 
groupadd -g 1000 mongodb
useradd -u 1000 -g mongodb mongodb
passwd mongodb
密码：mongodb
mkdir /mongodb
chown mongodb:mongodb /mongodb
--修改原文件系统挂载到/mongodb
vi /etc/fstab
umount /data
mount -a
chown mongodb:mongodb /mongodb
 
--解压软件：
su - mongodb
cd /mongodb
mkdir data conf soft log
cd soft
mkdir 3.2.22
cd 3.2.22
--先行上传安装包到/mongodb目录
tar -xzvf /mongodb/mongodb-linux-x86_64-rhel62-3.2.22.tgz
cd mongodb-linux-x86_64-rhel62-3.2.22
mv * ../
cd ../
rm -r mongodb-linux-x86_64-rhel62-3.2.22
 
--添加环境变量
cd
vi .bash_profile
添加
export PATH=$PATH:/mongodb/soft/3.2.22/bin
source .bash_profile
 
--操作系统参数配置--
vi /etc/hosts
 
10.10.1.5 MongoDB01
10.10.1.6 MongoDB02
10.10.1.7 MongoDB03
10.10.1.8 MongoDB04
10.10.1.9 MongoDB05
10.10.1.10 MongoDB06
10.10.1.11 MongoDB07
10.10.1.12 MongoDB08
10.10.1.13 MongoDB09
10.10.1.14 MongoDB10
10.10.1.15 MongoDB11
10.10.1.16 MongoDB12
 
--关闭selinux

getenforce
vi /etc/selinux/config

--关闭防火墙：

chkconfig ip6tables off

--修改系统参数：
vi /etc/sysctl.conf

sysctl -p
 
--关闭透明大页：
vi /etc/rc.local
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then
   echo never > /sys/kernel/mm/transparent_hugepage/enabled
fi
if test -f /sys/kernel/mm/transparent_hugepage/defrag; then
   echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
 
--设置mongodb用户的limits
vi /etc/security/limits.conf
mongodb soft nproc 4095
mongodb hard nproc 16384
mongodb soft nofile 8192
mongodb hard nofile 65536
mongodb soft stack 10240
mongodb hard stack 32768
 
vi /etc/security/limits.d/90-nproc.conf
添加
mongodb soft nproc unlimited
 
 
二、mongodb副本集配置（数据节点和配置节点）：
su - mongodb
mkdir /mongodb/data/28001
mkdir /mongodb/conf/28001
mkdir /mongodb/log/28001
cd /mongodb/conf/28001
 
openssl rand -base64 102 > .keyFile
chmod 400 .keyFile
将文件拷到其它节点相同目录下
 
vi mongo_sh1rs_28001.conf            --不同sh的配置文件全称不同
 
port = 28001
dbpath = /mongodb/data/28001
logpath = /mongodb/log/28001
pidfilepath = /mongodb/data/28001/28001.pid
logappend = true
fork = true
oplogSize = 204800
replSet = SH1RS                             --其它对应为SH2RS/SH3RS/SH4RS
#keyFile = /mongodb/conf/28001/.keyFile
 
--启动mongod
numactl --interleave=all mongod -f /mongodb/conf/28001/mongo_sh1rs_28001.conf
 
--配置副本集
repConfig = {
              _id:'SH1RS', 
     members:[
         {_id:0,host:'MongoDB01:28001'},
      {_id:1,host:'MongoDB02:28001'},
      {_id:2,host:'MongoDB03:28001'}]
   }
 
rs.initiate(repConfig)
rs.status()
