docker部署MongoDB数据库的实现步骤

docker pull mongo

mkdir -p /home/bigdata/mongodb_bigdata/data
mkdir -p /home/bigdata/mongodb_bigdata/conf
mkdir -p /home/bigdata/mongodb_bigdata/logs

docker run -dit --name mongodb -p 27019:27017 \
-v /home/bigdata/mongodb_bigdata/data:/data/db \
-v /home/bigdata/mongodb_bigdata/conf:/data/configdb \
-v /home/bigdata/mongodb_bigdata/logs:/data/log/ \
--restart always -d mongo

docker exec -ti mongodb /bin/bash

db.createUser({user:"root",pwd:"123456",roles:[{role:'root',db:'admin'}]}) 

# 创建库
use bigdata_db;

# 创建读写帐号
db.createUser(
     {
       user: "bigdata_rw",
       pwd: "11111111",
       roles: [
          { role: "readWrite", db: "bigdata_db" }    
       ]
     }
 )

# ------------------------------ mongodb连接信息配置 -------------------------------
# 读写
username = 'bigdata_rw'
password = '2222'
ip = 'xx.xxx.xx.xx'
port = 27019
database = 'bigdata_db'
mongodb_info = f"mongodb://{username}:{password}@{ip}:{port}/{database}"

# ---------------------------------------------------------------------------------

connection = pymongo.MongoClient(mongodb_info)

# 链接
db_name = connection['bigdata_db']
collection_name = db_name[mongodb_table_name]

# 查询结果
result_data = collection_name.find()

for i in result_data:
    print('the i is :', i)

apt-get update
apt-get install vim

vim ~/.bashrc

# 进入到编辑页面，添加如下内容：
alias ll='ls -l'

# 使命令生效
source ~/.bashrc
