docker利用dockerfile生成基础后端环境java8+git+maven

1. 创建dockerfile文件

   FROM centos:7
   RUN yum -y update \
       && yum -y install vim \
       && yum -y install git \
       && yum -y install java-1.8.0-openjdk-devel.x86_64 \
       && yum install -y maven \
       && mkdir ~/.m2
   RUN echo '<?xml version="1.0" encoding="UTF-8"?><settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"><mirrors><mirror><id>alimaven</id><mirrorOf>central</mirrorOf><name>aliyun maven</name><url>http://maven.aliyun.com/nexus/content/repositories/central/</url></mirror></mirrors></settings>' > ~/.m2/settings.xml
   
   
   

2. 在当前创建的dockerfile目录下

   docker build -t java8pro .
   

3. 根据镜像生成容器

   docker run -it --name centos7Java8  java8pro bash
   

4. 查看容器

   docker ps
   

5. 重启停止的容器

   docker start 停止的容器id
   

6. docker对容器重命名

   docker rename 原名称 新
   

docker安装mysql

1. 安装

   docker pull mysql:5.6

2. 生成容器

   docker run -p 3306:3306 --name mysql -v /project/mysql/conf:/etc/mysql/conf.d -v/project/mysql/logs:/logs -v/project/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Lzx15518947191. -d mysql:5.6
   
   

   命令说明：

   -p 3306:3306：将主机的3306端口映射到docker容器的3306端口。

   –name mysql：运行服务名字

   -v /project/mysql/conf:/etc/mysql/conf.d ：将主机/project/mysql录下的conf/my.cnf 挂载到容器的 /etc/mysql/conf.d

   -v /zzyyuse/mysql/logs:/logs：将主机/project/mysql目录下的 logs 目录挂载到容器的 /logs。

   -v /zzyyuse/mysql/data:/var/lib/mysql ：将主机/project/mysql目录下的data目录挂载到容器的 /var/lib/mysql

   -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用户的密码。

   -d mysql:5.6 : 后台程序运行mysql5.6

3. mysql设置密码

    set password for root@localhost = password('123456');  
    
   

4. mysql5.7时间戳问题

   set sql_mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION";

docker 安装redis

1. 安装

   docker pull redis:3.2

2. redis启动

   docker run -p 6379:6379 -v /project/myredis/data:/data -v /project/myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf  -d redis:3.2 redis-server /usr/local/etc/redis/redis.conf --appendonly yes

3. redis 设置密码

   redis-cli
   config set requirepass 123456

docker容器中无法使用vim等命令

  1. 更换apt-get的源 ，然后更行apt-get

mv /etc/apt/sources.list /etc/apt/sources.list.bak
echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
apt-get update 

2. 安装yum

   apt-get intall yum
   

​

3. 通过yum可以进行其他的安装
