安裝并遷移mongodb數(shù)據(jù)

之前通過golang連接安裝好的mongodb一直不成功，今天重新安裝部署下mongodb，并且做了一次數(shù)據(jù)遷移，結(jié)果是成功的。
參考文檔：
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/

操作步驟

1. 移除已經(jīng)安裝的mogodb
   yum erase $(rpm -qa | grep mongodb-org)
   移除之前的日志目錄，數(shù)據(jù)目錄
   rm -rf /app/mongodb/log/*
   rm -rf /app/mongodb/data/*
2. 配置yum源：
   創(chuàng)建文件：
   /etc/yum.repos.d/mongodb-org-4.4.repo
   內(nèi)容如下：

[mongodb-org-4.4]
name=MongoDB Repository
baseurl=http://mirrors.aliyun.com/mongodb/yum/redhat/7Server/mongodb-org/4.4/x86_64/
gpgcheck=0
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

3. 安裝： mongodb-org

yum install -y mongodb-org

4.修改默認(rèn)配置文件/etc/mongod.conf ，修改后文件如下：

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /app/mongodb/log/mongod.log

# Where and how to store data.
storage:
  dbPath: /app/mongodb/data
  journal:
    enabled: true
#  engine:
#  wiredTiger:

# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0  5

5. 授權(quán)
   mkdir -p /app/mongodb/log/
   mkdir -p /app/mongodb/data
   chown -R mongodb:mongodb /app/mongodb/log/
   chown -R mongodb:mongodb /app/mongodb/data
6. 關(guān)閉selinux ，并重啟主機(jī)

setenforce　0
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config 
reboot  ##重啟主機(jī)

7. 啟動服務(wù)：

systemctl daemon-reload
systemctl start mongod

8.啟動報(bào)錯：
提示無法操作/tmp/mongodb-27017.sock

{"t":{"$date":"2020-09-21T12:19:08.370+08:00"},"s":"E",  "c":"NETWORK",  "id":23024,   "ctx":"initandlisten","msg":"Failed to unlink socket file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Operation not permitted"}}

增加權(quán)限

chown -R mongod:mongod  /tmp/mongodb-27017.sock

9. 創(chuàng)建用戶以及集合

[root@prd-server-000834 log]# mongo
MongoDB shell version v4.4.0
> use admin
switched to db admin
> db.createUser({user: "root",pwd: "root",roles: [ { role: "root", db: "admin" } ]})

 >  db.createUser(
  {
    user: "XXX",
    pwd: "XXX",  // or cleartext password
    roles: [
       { role: "clusterAdmin", db: "admin" },
       { role: "userAdminAnyDatabase", db: "admin" },
       { role: "root", db: "admin" }
    ]
  }
> use XXX
>db.XXX.insert({"name":"check"})

9. 檢查db是否可以正常提供服務(wù)

mongo mongodb://XXX:XXX@localhost/XXX

10. 數(shù)據(jù)導(dǎo)出：

mongoexport -h localhost -d oms -c publish_log -o /app/backup/publish_log.json
mongoexport -h localhost -d oms -c publish_state -o /app/backup/publish_state.json
mongoexport -h localhost -d oms -c publish_task -o /app/backup/publish_task.json
mongoexport -h localhost -d oms -c service -o /app/backup/service.json
mongoexport -h localhost -d oms -c serviceVersion -o /app/backup/serviceVersion.json
mongoexport -h localhost -d oms -c user -o /app/backup/user.json

11. 數(shù)據(jù)導(dǎo)入:

mongoimport -d oms -c publish_log --file publish_log.json 
mongoimport -d oms -c publish_state --file publish_state.json 
mongoimport -d oms -c publish_task --file publish_task.json 
mongoimport -d oms -c service --file service.json 
mongoimport -d oms -c serviceVersion --file serviceVersion.json 
mongoimport -d oms -c user --file user.json 

12.導(dǎo)入導(dǎo)出，中間涉及tar 以及解壓，scp，就不寫了~~
