使用单机部署为副本集(开启oplog.rs)-4.4.13

环境:
OS:Centos 7
db:4.4.13

1.下载相应的版本
https://www.mongodb.com/download-center/community
我这里下载的是mongodb-linux-x86_64-rhel70-4.4.13.tgz

2.创建安装目录
[root@test services]# mkdir -p /usr/local/services
[root@test services]# mkdir -p /home/middle/mongodb/data
[root@test services]# mkdir -p /home/middle/mongodb/log
[root@test services]# mkdir -p /home/middle/mongodb/key
[root@test services]# mkdir -p /home/middle/mongodb/conf
[root@test services]# mkdir -p /home/middle/mongodb/run

3.安装数据库
[root@test soft]# tar -xvf mongodb-linux-x86_64-rhel70-4.4.13.tgz
[root@test soft]# mv mongodb-linux-x86_64-rhel70-4.4.13 /usr/local/services/mongodb

4.创建配置文件

[root@localhost conf]# more mongo_yaml.cnf 
net:
  bindIp: 192.168.204.53,127.0.0.1
  port: 28001

storage:
  journal:
    enabled: true
  dbPath: "/home/middle/mongodb/data"
  engine: wiredTiger
  wiredTiger:
    engineConfig:
      cacheSizeGB: 6

systemLog:
  destination: file
  path: "/home/middle/mongodb/log/mongodb.log"
  logAppend: true
  logRotate: reopen

processManagement:
  fork: true
  pidFilePath: "/home/middle/mongodb/run/28001.pid"

replication:
  oplogSizeMB: 16384
  replSetName: s1

##security:
##  keyFile: "/home/middle/mongodb/key/keyfile"
##  authorization: "enabled"

5.产生秘钥验证
在其中一个机器上创建秘钥文件,我这里是在192.168.1.105上操作
[root@test key]# cd /home/middle/mongodb/key
[root@test key]# openssl rand -base64 741 >>keyfile
[root@test key]# chmod 700 keyfile

6.启动
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf

7.登录并初始化副本集

/usr/local/services/mongodb/bin/mongo 192.168.204.53:28001
use admin
config={_id:'s1',members:[{_id:0,host:'192.168.204.53:28001'}]}
rs.initiate(config)

8.创建管理员用户

[root@localhost bin]# /usr/local/services/mongodb/bin/mongo 192.168.204.53:28001
use admin
db.createUser({user:"root",pwd:"root123",roles:["root"]}); --创建用户
db.auth("root","root123");                                                  --设置用户登陆权限，密码一定要和创建用户时输入的密码相同
show users;                                                                 --查看创建的用户

9.关闭服务
/usr/local/services/mongodb/bin/mongo localhost:28001
use admin
db.shutdownServer()

10.启用验证参数

##security:
##  keyFile: "/home/middle/mongodb/key/keyfile"
##  authorization: "enabled"

修改为:

security:
  keyFile: "/home/middle/mongodb/key/keyfile"
  authorization: "enabled"

11.重新启动
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf

12.登录
/usr/local/services/mongodb/bin/mongo 192.168.204.53:28001
use admin
db.auth("root","root123");
