（Ubuntu）Docker的安装与使用

本篇使用的系统是Ubuntu

一.Docker安装

进入命令行

安装组件的时候如果报资源锁，重启一下

安装组件：sudo apt install curl

在这里插入图片描述

1.镜像比较大, 需要准备一个网络稳定的环境
2.其中–mirror Aliyun代表使用阿里源

下载路径：sudo curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

在这里插入图片描述

下载完成后查看一下版本信息：docker -v

在这里插入图片描述

二.创建容器

拉取镜像：sudo docker pull centos:7

在这里插入图片描述

启动并创建容器：

sudo docker run -itd --privileged --name singleNode -h singleNode \
-p 2222:22 \
-p 3306:3306 \
-p 50070:50070 \
-p 8088:8088 \
-p 8080:8080 \
-p 10000:10000 \
-p 60010:60010 \
-p 9092:9092 \
centos:7 /usr/sbin/init

在这里插入图片描述

进入容器：sudo docker exec -it singleNode /bin/bash

在这里插入图片描述

此时就成功进入容器

三.Docker中搭建大数据环境

安装组件

yum clean all
yum -y install unzip bzip2-devel vim bashname

配置SSH免密登录

yum install -y openssh openssh-server openssh-clients openssl openssl-devel 
ssh-keygen -t rsa -f ~/.ssh/id_rsa -P '' 
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# 启动SSH服务
systemctl start sshd

设置时区

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

在这里插入图片描述

如果有防火墙需要关闭一下：

systemctl stop firewalld
systemctl disable firewalld

创建文件夹：

#存放解压包
mkdir -p /opt/install

退出容器：exit
将大数据组件包上传至Ubuntu中的一个目录下，创建目录名为software
将Ubuntu中的组件包复制一份到容器中

sudo docker cp /home/zy/software/ singleNode:/opt/

重新进入容器

sudo docker exec -it singleNode /bin/bash

安装MySQL

进入到安装包路径下

cd /opt/software

解压包

tar zxvf MySQL-5.5.40-1.linux2.6.x86_64.rpm-bundle.tar -C /opt/install

安装依赖

yum -y install libaio perl

安装服务端和客户端

#先到MySQL解压后的路径
cd /opt/install
#安装服务端
rpm -ivh MySQL-server-5.5.40-1.linux2.6.x86_64.rpm
#安装客户端
rpm -ivh MySQL-client-5.5.40-1.linux2.6.x86_64.rpm

启动并配置MySQL

#第一步：启动
systemctl start mysql
#第二步：配置用户名密码
/usr/bin/mysqladmin -u root password 'root'
#第三步：进入mysql
mysql -uroot -proot 
#第四步：配置
> update mysql.user set host='%' where host='localhost';
> delete from mysql.user where host<>'%' or user='';
> flush privileges;
#安装完成退出
quit

解压包

tar zxvf /opt/software/jdk-8u171-linux-x64.tar.gz -C /opt/install/

配置环境变量：

vi /etc/profile
#添加以下配置信息
export JAVA_HOME=/opt/install/java
export PATH=$JAVA_HOME/bin:$PATH

生效配置文件：

source /etc/profile

查看Java版本：

java -version
