一.部署nodejs項目,映射端口,掛載數(shù)據(jù)卷

可以到https://hub.docker.com/去搜索node鏡像,然后下載,也可以直接通過docker pull node下載鏡像,然后用這個node鏡像啟動容器node,這樣系統(tǒng)就集成了node服務(wù)了,在這里掛載www/node目錄到容器中,并指定端口映射,運行nodejs程序,安裝npm,以及對應(yīng)的依賴,啟動node目錄下對應(yīng)的項目,然后通過瀏覽器訪問,看看是否成功

1.安裝 nodejs

#下載node鏡像

2.啟動node容器,映射端口,掛載數(shù)據(jù)卷

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

#查看啟動的容器

3.進入容器,查看node版本,以及安裝cnpm,安裝依賴

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

#查看node版本:發(fā)現(xiàn)存在,說明node安裝完成,因為是使用docker安裝nodejs,所以容器中就會自動安裝node

  }
}

#需要安裝依賴:這里可以通過npm來下載,不過npm可能會失敗,所以使用cnpm來安裝
#要使用cnpm,就需要安裝: npm install cnpm -g --registry=https://registry.nlark.com

?4.后臺運行程序,瀏覽器訪問

5.修改app.js,重啟node,查看修改是否成功

因為修改node項目后,需要重啟node,故修改項目中的app.js代碼后,需要進入容器,重新啟動node才能看見修改變化

app.js修改

var express = require('express');

var app=express();

app.get('/',function(req,res){
        res.send('首頁update');
})
app.get('/news',function(req,res){
        res.send('首頁');
})

//docker做端口映射的時候不要指定ip
app.listen(3000);

重啟node

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

#查看運行的node
root@c28cc83c4ba3:/# ps -aux
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

#停止node程序

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

二.部署Mysql,遠程連接Mysql,Mysql數(shù)據(jù)持久化

可以到https://hub.docker.com/或者Docker去搜索mysql鏡像,然后下載,也可以直接通過docker pull mysql下載鏡像,然后用這個mysql鏡像啟動容器mysql,這樣系統(tǒng)就集成了mysql服務(wù)了

1.下載 mysql

#下載mysql

2.啟動mysql容器

#通過mysql鏡像,啟動一個mysql容器,這里需要映射端口,輸入密碼
[root@localhost zph]# docker run -it -d --name mymysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 a3b6608898d6
0f51776fd2edce3d6479a9296a25c8b9b84a35742c9b21171a0860ec4b564e2a
[root@localhost zph]# 

#查看是否啟動mysql容器
[root@localhost zph]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                                  NAMES

?3.進入容器

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

#進入mysql,并輸入密碼
bash-4.4# mysql -u root -p
Enter password:

#輸入123456密碼后,能夠進入mysql數(shù)據(jù)庫,說明容器ok,然后exit退出
mysql> exit
Bye
bash-4.4# exit
exit

4.外部連接mysql

通過外部的Navicat訪問mysql容器

(1).查看電腦的ip

通過ip addr 查看ip

[root@localhost zph]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> 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
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> 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
    inet 192.168.0.6/24 brd 192.168.0.255 scope global dynamic noprefixroute ens33
       valid_lft 168896sec preferred_lft 168896sec
    inet6 fe80::20c:29ff:fec3:3d27/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

(2).通過Navicat連接mysql容器

(3).在容器中查看是否創(chuàng)建了數(shù)據(jù)庫

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

#輸入密碼,進入mysql數(shù)據(jù)庫
bash-4.4# mysql -u root -p
Enter password:

?5.映射端口 , 掛載配置文件目錄,掛載數(shù)據(jù)文件目錄,啟動mysql

默認數(shù)據(jù)庫的數(shù)據(jù)是放在容器里面的，這樣的話當(dāng)容器刪除會導(dǎo)致數(shù)據(jù)丟失,如果要實現(xiàn) 當(dāng)刪除容器的時候不刪除容器里面的mysql數(shù)據(jù) ，這個時候啟動容器的時候就可以把 mysql 數(shù)據(jù)

掛載到外部

(1).映射端口,掛載配置文件,數(shù)據(jù)文件目錄,啟動mysql容器?

這里,需要把mysql的配置文件,以及數(shù)據(jù)文件映射到容器中的,在linux /var/www/mysql下創(chuàng)建conf.d,data文件夾,用來保存配置文件以及數(shù)據(jù)文件,這樣,當(dāng)不小心刪除了容器,再次啟動一個容器時,就可以把配置以及數(shù)據(jù)映射到容器中,避免數(shù)據(jù)的丟失?

#查看mysql
[root@localhost zph]# docker ps

(4).刪除容器,重啟啟動一個容器,查看數(shù)據(jù)是否保存

$查看當(dāng)前運行中的容器
[root@localhost data]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED          STATUS          PORTS                                                  NAMES
7b133357d04a   a3b6608898d6   "docker-entrypoint.s…"   13 minutes ago   Up 13 minutes   0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp   mymysql

#刪除mysql容器:這時外網(wǎng)連接不上mysql容器了,數(shù)據(jù)保存在/var/www/mysql/中
[root@localhost data]# docker rm -f 7b133357d04a
7b133357d04a

#查看刪除是否成功
[root@localhost data]# docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

#重新創(chuàng)建一個mysql容器
[root@localhost data]# docker run -it -d --name mymysql_bak -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -v /var/www/mysql/conf.d:/etc/mysql/conf.d -v /var/www/mysql/data/:/var/lib/mysql a3b6608898d6
a54a9c659b12c8c2a329a22f4a59994e2ccbf9f72470e2ba6ba4b5bc66d9d328

#mysql容器創(chuàng)建成功
[root@localhost data]# docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED              STATUS              PORTS                                                  NAMES
a54a9c659b12   a3b6608898d6   "docker-entrypoint.s…"   About a minute ago   Up About a minute   0.0.0.0:3306->3306/tcp, :::3306->3306/tcp, 33060/tcp   mymysql_bak
[root@localhost data]# 

再次連接mysql,能夠連接,說明數(shù)據(jù)保存在本地,沒問題,當(dāng)刪除容器后,數(shù)據(jù)沒有丟失

三.部署Redis,遠程連接Redis,啟動容器配置密碼

可以到https://hub.docker.com/或者Docker去搜索redis鏡像,然后下載,也可以直接通過docker pull redis下載鏡像,然后用這個redis鏡像啟動容器redis,這樣系統(tǒng)就集成了redis服務(wù)了

1.下載redis鏡像并啟動容器,然后本地連接

#下載redis
[root@localhost zph]# docker pull redis
Using default tag: latest
latest: Pulling from library/redis
a378f10b3218: Already exists 
b266cd8112a6: Pull complete

#通過鏡像啟動一個redis容器
[root@localhost zph]# docker run -it -d --name -p 2379:2379 myredis1 e579380d4317

#查看是否啟動了redis容器
[root@localhost zph]# docker ps

#進入reids容器
[root@localhost zph]# docker exec -it 41d9fd8b87d3 /bin/bash

#連接redis
root@41d9fd8b87d3:/data# redis-cli 

#設(shè)置數(shù)據(jù)key=>value
127.0.0.1:6379> set username zhangsan
OK
127.0.0.1:6379> set age 10
OK

#獲取數(shù)據(jù):說明redis容器ok
127.0.0.1:6379> get username
"zhangsan"
127.0.0.1:6379> get age
"10"

2.遠程連接

如果需要在遠程 redis 服務(wù)上執(zhí)行命令，同樣使用的也是 redis-cli 命令,語法:

????????

#-h 服務(wù)器地址 -p 端口號
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.啟動redis容器,配置密碼

配置密碼后,訪問redis時就需要輸入密碼,這樣安全性就高了,通過 --requirepass 可以配置密碼

#啟動redis容器,并配置訪問密碼
[root@localhost zph]# docker run -it -d --name myredis3 -p 2379:2379 e579380d4317 --requirepass "123456"
804b873aa59c00acbba1dd77fdbcb3d1a7e52db1b93b9b9693bd775608ca83ba

#查看是否啟動了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]# 

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

#啟動redis客戶端
root@804b873aa59c:/data# redis-cli

#獲取數(shù)據(jù):提示沒得權(quán)限
127.0.0.1:6379> get *
(error) NOAUTH Authentication required.

#授權(quán)訪問:輸入密碼
127.0.0.1:6379> auth 123456
OK

#設(shè)置數(shù)據(jù)并訪問,操作成功
127.0.0.1:6379> set username zhangsan
OK
127.0.0.1:6379> get username
"zhangsan"
127.0.0.1:6379> 

?4.遠程連接(有密碼的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
OK

四.部署Mongodb,配置密碼 遠程連接

可以到https://hub.docker.com/或者Docker去搜索mongodb鏡像,然后下載,也可以直接通過docker pull mongodb下載鏡像,然后用這個mongodb鏡像啟動容器mongodb,這樣系統(tǒng)就集成了mongodb服務(wù)了

1.下載mongodb鏡像并啟動容器,然后本地連接(不需要密碼)

?

在啟動容器的時候,可以先使用-p映射端口,以及-v掛載數(shù)據(jù)目錄,這樣就可以數(shù)據(jù)持久化了

可以通果docker inspect mongo | grep data查看映射關(guān)系

2.遠程連接

需要在遠程服務(wù)器上安裝mongo

C:\Users\zph>mongo 192.168.0.6:27017

3.啟動mongo容器,配置密碼

配置密碼后,訪問mongo時就需要輸入密碼,這樣安全性就高了,語法:

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

#通過mongo鏡像啟動一個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

#查看是否啟動容器

> Successfully added user: { "user" : "zhangsan", "roles" : [
{
    role" : "userAdminAnyDatabase", "db" : "admin"
},"readWriteAnyDatabase"
]
}

4.遠程連接(有密碼)

注意加上數(shù)據(jù)庫表

mongo 192.168.0.6:27017/zhangsan

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