    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 setenforce 0 getenforce vi /etc/selinux/config SELINUX=disabled   --关闭防火墙： chkconfig iptables off chkconfig ip6tables off service iptables stop service ip6tables stop   --修改系统参数： vi /etc/sysctl.conf   fs.file-max = 6815744 kernel.sem = 10000 1280000 512 1024 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 net.core.rmem_default = 262144 net.core.wmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_max = 1048576 fs.aio-max-nr = 4194304 vm.dirty_ratio=20 vm.dirty_background_ratio=3 vm.dirty_writeback_centisecs=100 vm.dirty_expire_centisecs=500 vm.swappiness=10 vm.min_free_kbytes=524288   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()                       1
