mongodb复制集部署文档

一、安装SNMP（新版mongodb需要此依赖安装）

安装snmp服务需要的rpm包：

perl-Data-Dumper-2.145-3.el7.x86_64.rpm

net-snmp-5.7.2-28.el7_4.1.x86_64.rpm

net-snmp-agent-libs-5.7.2-28.el7_4.1.x86_64.rpm

net-snmp-libs-5.7.2-28.el7_4.1.x86_64.rpm

https://download.csdn.net/download/weixin_42903334/10901084 文档以及下载地址CSDN链接

安装步骤：

(1)将这个几rpm包放到任意目录下，进入到这个目录，执行命令 rpm -ivh net-snmp*.rpm --force

例如，将这几个rpm包放在 /root目录下，然后进入这个目录 cd /root, 然后执行命令

rpm -ivh net-snmp*.rpm --force 安装完成之后，这几个rpm包就可以删掉了。

(2)修改配置文件(/etc/snmp/snmpd.conf),大家可以参考http://www.linuxde.net/2013/02/12269.html对snmp进行符合自己要求的配置，如果你嫌麻烦，可以直接用我配置好的snmpd.conf覆盖过去，基本能满足我们日常开发需求，步骤就是把压缩包里的snmpd.conf复制到/etc/snmp/snmpd.conf目录下，覆盖。

(3)最后启动服务，执行命令 systemctl start snmpd

(4)测试验证SNMP配置的正确性，执行命令

snmpwalk -v 1 192.168.0.200 -c public system

(注意，192.168.0.200更改为自己安装snmp服务的那台机器地址)

表明安装成功!!!

二、mongodb配置，顺序一定不能错

创建相关目录

添加mongodb环境变量

echo 'export PATH=/usr/local/mongodb/bin:$PATH' >> /etc/profile

source /etc/profile

[root@roothost-10-90-2-105 mongodb4.0.2]# mkdir data logs # 数据目录和日志目录

新建配置文件(两个节点的配置一下只有存数据的目录不同)

[root@roothost-10-90-2-105 mongodb4.0.2]# cat mongodb.conf

logpath=/usr/local/mongodb/logs/mongod.log # 日志路径

logappend=true # 是否日志追加

fork=true # 后台启动

port=27017 # 端口

dbpath=/usr/local/mongodb/data/mongodb_bak/mongodb_bak_now # 数据目录

pidfilepath=/usr/local/mongodb/data/mongod.pid # pid

oplogSize=4096 # 设置oplog的大小

maxConns=640000 # 最大同时连接数默认2000

directoryperdb=true # 设置每个数据库将被保存在一个单独的目录

bind_ip=0.0.0.0 # 监听 0.0.0.0 代表可以被访问连接

启动主节点

[root@roothost-10-90-2-105 mongodb4.0.2]#./bin/mongod -f mongodb.conf # 主

进入主节点并新建root账号

[root@roothost-10-90-2-105 mongodb4.0.2]#mongo

MongoDB shell version v4.0.2

connecting to: mongodb://127.0.0.1:27017

MongoDB server version: 4.0.2> db.createUser({ user: 'root', pwd: 'test123', roles: [ { role:"root", db: "admin" } ] });

Successfully added user: {

"user" : "root",

"roles" : [

{

"role" : "root",

"db" : "admin"

}

]}>

停止主节点

[root@roothost-10-90-2-105 mongodb4.0.2]#./bin/mongod -f mongodb.conf # 主

启用密码认证和keyfile证书验证

把主节点上生成的energy-rc.key传到从节点上，配置同主节点一样（记得对传过去的文件也得同样赋权限）

# 生成keyfiles文件[root@roothost-10-90-2-105 mongodb4.0.2]#openssl rand -base64 756 > energy-rc.key

# 设置只读权限[root@roothost-10-90-2-105 mongodb4.0.2]#chmod 400 energy-rc.key

# 配置文件中添加如下[root@roothost-10-90-2-105 mongodb4.0.2]#cat mongodb.conf

auth=true #打开认证

keyFile=/root/mongodb4.0.2/energy-rc.key #启用key验证

replSet=rs0

启动主从节点

[root@roothost-10-90-2-105 mongodb4.0.2]#./bin/mongod -f mongodb.conf # 主[root@server mongodb4.0.2]#./bin/mongod -f mongodb.conf # 从

进入主节点添加副本集节点

现在副本集主从状态已经建立了,接下来就测试下数据能不能正常同步

测试同步

在主上插入一条数据

rs0:PRIMARY> use pay

switched to db pay

rs0:PRIMARY> db.pay.insert({"_id":"1"})WriteResult({ "nInserted" : 1 })

rs0:PRIMARY>

然后在从节点上查看是否已同步

rs0:SECONDARY> use admin

switched to db admin

rs0:SECONDARY> db.auth('root','test123')

rs0:SECONDARY> show dbs;
