[Docker]四.Docker部署nodejs项目,部署Mysql,部署Redis,部署Mongodb

一.部署nodejs项目,映射端口,挂载数据卷

可以到https://hub.docker.com/去搜索node镜像,然后下载,也可以直接通过docker pull node下载镜像,然后用这个node镜像启动容器node,这样系统就集成了node服务了,在这里挂载www/node目录到容器中,并指定端口映射,运行nodejs程序,安装npm,以及对应的依赖,启动node目录下对应的项目,然后通过浏览器访问,看看是否成功

1.安装 nodejs

#下载node镜像

[root@localhost www]# docker pull node

Using default tag: latest

latest: Pulling from library/node

a360c7bc21d1: Pull complete

#查看是否存在镜像node

[root@localhost www]# docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

node latest 51bf29046591 44 hours ago 1.1GB

2.启动node容器,映射端口,挂载数据卷

[root@localhost node]# docker run -it -d --name mynode -p 3000:3000 -v /var/www/node/:/var/www/node/ 51bf29046591 /bin/bash

#查看启动的容器

[root@localhost node]# docker ps

3.进入容器,查看node版本,以及安装cnpm,安装依赖

#进入容器

[root@localhost node]# docker exec -it c28cc83c4ba3 /bin/bash

#查看node版本:发现存在,说明node安装完成,因为是使用docker安装nodejs,所以容器中就会自动安装node

root@c28cc83c4ba3:/var/www# node -v

v21.1.0

#查看项目文件

root@c28cc83c4ba3:/var/www# ls

app.js package.json

#查看项目需要的依赖

root@c28cc83c4ba3:/var/www# cat package.json

"dependencies": {

"ejs": "^2.5.6",

"express": "^4.15.3",

"socket.io": "^2.0.3",

"body-parser": "~1.17.1"

}

#需要安装依赖:这里可以通过npm来下载,不过npm可能会失败,所以使用cnpm来安装

#要使用cnpm,就需要安装: npm install cnpm -g --registry=https://registry.nlark.com

root@c28cc83c4ba3:/var/www# npm install cnpm -g --registry=https://registry.nlark.com

4.后台运行程序,浏览器访问

#后台运行程序: nohup node app.js &, 当然,也可以node app.js,这个命令会卡死在这儿,不会后台运行

root@c28cc83c4ba3:/var/www# nohup node app.js &

root@c28cc83c4ba3:/var/www# nohup: ignoring input and appending output to 'nohup.out'

#容器内访问,看看是否成功,发现成功

root@c28cc83c4ba3:/var/www# curl 127.0.0.1:3000

首页root@c28cc83c4ba3:/var/www#

#退出容器

root@c28cc83c4ba3:/var/www# exit

exit

#查看ip,然后通过ip在浏览器中访问

[root@localhost node]# ip addr

1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft 160539sec preferred_lft 160539sec

5.修改app.js,重启node,查看修改是否成功

因为修改node项目后,需要重启node,故修改项目中的app.js代码后,需要进入容器,重新启动node才能看见修改变化

app.js修改

var express = require('express');

var app=express();

app.get('/',function(req,res){

res.send('首页update');

})

app.get('/news',function(req,res){

res.send('首页');

})

//docker做端口映射的时候不要指定ip

app.listen(3000);

重启node

#进入node容器

[root@localhost node]# docker exec -it c28cc83c4ba3 /bin/bash

#查看运行的node

root@c28cc83c4ba3:/# ps -aux

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

[1] 242

root@c28cc83c4ba3:/var/www# nohup: ignoring input and appending output to 'nohup.out'

二.部署Mysql,远程连接Mysql,Mysql数据持久化

可以到https://hub.docker.com/或者Docker去搜索mysql镜像,然后下载,也可以直接通过docker pull mysql下载镜像,然后用这个mysql镜像启动容器mysql,这样系统就集成了mysql服务了

1.下载 mysql

#下载mysql

[root@localhost zph]# docker pull mysql

2.启动mysql容器

#通过mysql镜像,启动一个mysql容器,这里需要映射端口,输入密码

[root@localhost zph]# docker run -it -d --name mymysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 a3b6608898d6

0f51776fd2edce3d6479a9296a25c8b9b84a35742c9b21171a0860ec4b564e2a

3.进入容器

#进入mysql容器

[root@localhost zph]# docker exec -it 0f51776fd2ed /bin/bash

#进入mysql,并输入密码

bash-4.4# mysql -u root -p

Enter password:

Bye

bash-4.4# exit

exit

4.外部连接mysql

通过外部的Navicat访问mysql容器

(1).查看电脑的ip

通过ip addr 查看ip

[root@localhost zph]# ip addr

1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft forever preferred_lft forever

2: ens33: mtu 1500 qdisc fq_codel state UP group default qlen 1000

link/ether 00:0c:29:c3:3d:27 brd ff:ff:ff:ff:ff:ff

inet6 fe80::20c:29ff:fec3:3d27/64 scope link noprefixroute

valid_lft forever preferred_lft forever

(2).通过Navicat连接mysql容器

(3).在容器中查看是否创建了数据库

$#进入mysql容器

[root@localhost zph]# docker exec -it 0f51776fd2ed /bin/bash

#输入密码,进入mysql数据库

bash-4.4# mysql -u root -p

Enter password:

5.映射端口 , 挂载配置文件目录,挂载数据文件目录,启动mysql

默认数据库的数据是放在容器里面的，这样的话当容器删除会导致数据丢失,如果要实现

当删除容器的时候不删除容器里面的mysql数据

，这个时候启动容器的时候就可以把

mysql

数据

挂载到外部

(1).映射端口,挂载配置文件,数据文件目录,启动mysql容器

这里,需要把mysql的配置文件,以及数据文件映射到容器中的,在linux /var/www/mysql下创建conf.d,data文件夹,用来保存配置文件以及数据文件,这样,当不小心删除了容器,再次启动一个容器时,就可以把配置以及数据映射到容器中,避免数据的丢失

再次连接mysql,能够连接,说明数据保存在本地,没问题,当删除容器后,数据没有丢失

三.部署Redis,远程连接Redis,启动容器配置密码

可以到https://hub.docker.com/或者Docker去搜索redis镜像,然后下载,也可以直接通过docker pull redis下载镜像,然后用这个redis镜像启动容器redis,这样系统就集成了redis服务了

1.下载redis镜像并启动容器,然后本地连接

如果需要在远程

redis

服务上执行命令，同样使用的也是

redis-cli

命令,语法:

#-h 服务器地址 -p 端口号

redis-cli -h host -p port

C:\Users\zph>redis-cli -h 192.168.0.6 -p 6379

192.168.0.6:6379> get username

"zhangsan"

192.168.0.6:6379>

3.启动redis容器,配置密码

配置密码后,访问redis时就需要输入密码,这样安全性就高了,通过 --requirepass 可以配置密码

#启动redis容器,并配置访问密码

[root@localhost zph]# docker run -it -d --name myredis3 -p 2379:2379 e579380d4317 --requirepass "123456"

804b873aa59c00acbba1dd77fdbcb3d1a7e52db1b93b9b9693bd775608ca83ba

#查看是否启动了redis

[root@localhost zph]# docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

804b873aa59c e579380d4317 "docker-entrypoint.s…" 5 seconds ago Up 4 seconds 0.0.0.0:2379->2379/tcp, :::2379->2379/tcp, 6379/tcp myredis3

[root@localhost zph]#

#进入redis容器

[root@localhost zph]# docker exec -it 804b873aa59c /bin/bash

#启动redis客户端

root@804b873aa59c:/data# redis-cli

#获取数据:提示没得权限

127.0.0.1:6379> get *

(error) NOAUTH Authentication required.

#授权访问:输入密码

127.0.0.1:6379> auth 123456

#设置数据并访问,操作成功

127.0.0.1:6379> set username zhangsan

127.0.0.1:6379> get username

"zhangsan"

127.0.0.1:6379>

4.远程连接(有密码的redis)

#注意映射的端口: -p 的端口

C:\Users\zph>redis-cli -h 192.168.0.6 -p 6379

192.168.241.0.6> auth 123456

四.部署Mongodb,配置密码远程连接

可以到https://hub.docker.com/或者Docker去搜索mongodb镜像,然后下载,也可以直接通过docker pull mongodb下载镜像,然后用这个mongodb镜像启动容器mongodb,这样系统就集成了mongodb服务了

1.下载mongodb镜像并启动容器,然后本地连接(不需要密码)

在启动容器的时候,可以先使用-p映射端口,以及-v挂载数据目录,这样就可以数据持久化了

#下载mongo

[root@localhost ~]# docker pull mongo

Using default tag: latest

latest: Pulling from library/mongo

16ec32c2132b: Pull complete

--- The server generated these startup warnings when booting:

2021-07-28T04:25:25.178+00:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted

2021-07-28T04:25:25.178+00:00: /sys/kernel/mm/transparent_hugepage/enabled is

--- Enable MongoDB's free cloud-based monitoring service, which will then receive

and display

#展示数据库

WriteResult({ "nInserted" : 1 })

#查看数据表数据

可以通果docker inspect mongo | grep data查看映射关系

2.远程连接

需要在远程服务器上安装mongo

C:\Users\zph>mongo 192.168.0.6:27017

MongoDB shell version v4.2.5

connecting to: mongodb://192.168.0.6:27017/test?compressors=disabled&gssapiServiceN

3.启动mongo容器,配置密码

配置密码后,访问mongo时就需要输入密码,这样安全性就高了,语法:

docker run -d --name authMongo -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=123456 -p 27017:27017 -v /var/www/mongo/data:/data/db mongo --auth

#通过mongo镜像启动一个mongo容器

[root@localhost ~]#docker run -d --name authMongo -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=123456 -p 27017:27017 -v /var/www/mongo/data:/data/db mongo --auth

#查看是否启动容器

[root@localhost ~]# docker ps

#查看数据

> show dbs

admin 0.000GB

config 0.000GB

teset 0.000GB

local 0.000GB

#创建一个账号并授权

db.createUser({ user:'zhangsan',pwd:'123456',roles:[ { role:'userAdminAnyDatabase', db: 'admin'},"readWriteAnyDatabase"]});

> Successfully added user: { "user" : "zhangsan", "roles" : [

{

role" : "userAdminAnyDatabase", "db" : "admin"

},"readWriteAnyDatabase"

]

}

4.远程连接(有密码)

注意加上数据库表

mongo 192.168.0.6:27017/zhangsan

C:\Users\zph>mongo 192.168.0.6:27017/zhangsan
