linux记录-docker配置mysql

docker部署mysql

1.拉取镜像

docker pull mysql

2.docker  rm   containerID  删除镜像iD

3.创建镜像

docker run --name=mysql -it -p 3306:3306 -e MYSQL_ROOT_PASSWORD=0 -d mysql

4.查看创建的镜像

docker ps -a

5.启动镜像

docker start  containerID(找到mysql  容器id)

6.docker exec -it mysql bash进入容器bash

7.输入mysql  -uroot -p进行mysql

8.查看本地所有镜像

docker  images

9.搜索镜像

docker search tomcat

10.运行tomcat

docker run -p 8080:8080 docker.io/tomcat

 #############################################################################################

命名空间（namespaces）是 Linux 为我们提供的用于分离进程树、网络接口、挂载点以及进程间通信等资源的方法。
运行在同一台机器上的不同服务能做到完全隔离，就像运行在多台不同的机器上一样。
Docker 其实就通过 Linux 的 Namespaces 对不同的容器实现了隔离。

Chroot
在 Linux 系统中，系统默认的目录就都是以 / 也就是根目录开头的，chroot 的使用能够改变当前的系统根目录结构，通过改变当前系统的根目录，我们能够限制用户的权利，在新的根目录下并不能够访问旧系统根目录的结构个文件，也就建立了一个与原系统完全隔离的目录结构

CGroups
我们通过 Linux 的命名空间为新创建的进程隔离了文件系统、网络并与宿主机器之间的进程相互隔离，但是命名空间并不能够为我们提供物理资源上的隔离，比如 CPU 或者内存，如果在同一台机器上运行了多个对彼此以及宿主机器一无所知的『容器』，这些容器却共同占用了宿主机器的物理资源。
Control Groups（简称 CGroups）就是能够隔离宿主机器上的物理资源，例如 CPU、内存、磁盘 I/O 和网络带宽。
在 CGroup 中，所有的任务就是一个系统的一个进程，而 CGroup 就是一组按照某种标准划分的进程，在 CGroup 这种机制中，所有的资源控制都是以 CGroup 作为单位实现的，每一个进程都可以随时加入一个 CGroup 也可以随时退出一个 CGroup。

Docker 使用客户端-服务器 (C/S) 架构模式，使用远程API来管理和创建Docker容器。
Docker 容器通过 Docker 镜像来创建。
容器与镜像的关系类似于面向对象编程中的对象与类。

Docker 镜像(Images)
Docker 镜像是用于创建 Docker 容器的模板。
Docker 容器(Container)
容器是独立运行的一个或一组应用。
Docker 客户端(Client)
Docker 客户端通过命令行或者其他工具使用 Docker API (https://docs.docker.com/reference/api/docker_remote_api) 与 Docker 的守护进程通信。
Docker 主机(Host)
一个物理或者虚拟的机器用于执行 Docker 守护进程和容器。
Docker 仓库(Registry)
Docker 仓库用来保存镜像，可以理解为代码控制中的代码仓库。

1.安装nginx
docker search nginx
docker pull nginx
docker images nginx
docker run --name runoob-nginx-test -p 8081:80 -d nginx
runoob-nginx-test 容器名称。
the -d设置容器在在后台一直运行。
the -p 端口进行映射，将本地 8081 端口映射到容器内部的 80 端口。

docker ps查看是否有容器在运行
PORTS 部分表示端口映射，本地的 8081 端口映射到容器内部的 80 端口。
在浏览器中打开 http://127.0.0.1:8081/

mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf
拷贝容器内 Nginx 默认配置文件到本地当前目录下的 conf 目录，容器 ID 可以查看 docker ps 命令输入中的第一列：
docker cp 6dd4380ba708:/etc/nginx/nginx.conf ~/nginx/conf

www: 目录将映射为 nginx 容器配置的虚拟目录。
logs: 目录将映射为 nginx 容器的日志目录。
conf: 目录里的配置文件将映射为 nginx 容器的配置文件。

docker run -d -p 8082:80 --name runoob-nginx-test-web -v ~/nginx/www:/usr/share/nginx/html -v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v ~/nginx/logs:/var/log/nginx nginx

命令说明：
-p 8082:80： 将容器的 80 端口映射到主机的 8082 端口。
--name runoob-nginx-test-web：将容器命名为 runoob-nginx-test-web。
-v ~/nginx/www:/usr/share/nginx/html：将我们自己创建的 www 目录挂载到容器的 /usr/share/nginx/html。
-v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf：将我们自己创建的 nginx.conf 挂载到容器的 /etc/nginx/nginx.conf。
-v ~/nginx/logs:/var/log/nginx：将我们自己创建的 logs 挂载到容器的 /var/log/nginx。

重启 NGINX 容器命令：
$ docker restart container-name

2.安装php
docker search php
docker pull php:5.6-fpm
docker images
docker run --name myphp-fpm -v ~/nginx/www:/www -d php:5.6-fpm
命令说明：
--name myphp-fpm : 将容器命名为 myphp-fpm。
-v ~/nginx/www:/www : 将主机中项目的目录 www 挂载到容器的 /www
mkdir ~/nginx/conf/conf.d
在该目录下添加 ~/nginx/conf/conf.d/runoob-test-php.conf 文件，内容如下：
server {
listen 80;
server_name localhost;

location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

location ~ \.php$ {
fastcgi_pass php:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /www/$fastcgi_script_name;
include fastcgi_params;
}
}
配置文件说明：
php:9000: 表示 php-fpm 服务的 URL，下面我们会具体说明。
/www/: 是 myphp-fpm 中 php 文件的存储路径，映射到本地的 ~/nginx/www 目录。
启动 nginx：
docker run --name runoob-php-nginx -p 8083:80 -d \
-v ~/nginx/www:/usr/share/nginx/html:ro \
-v ~/nginx/conf/conf.d:/etc/nginx/conf.d:ro \
--link myphp-fpm:php \
nginx

-p 8083:80: 端口映射，把 nginx 中的 80 映射到本地的 8083 端口。
~/nginx/www: 是本地 html 文件的存储目录，/usr/share/nginx/html 是容器内 html 文件的存储目录。
~/nginx/conf/conf.d: 是本地 nginx 配置文件的存储目录，/etc/nginx/conf.d 是容器内 nginx 配置文件的存储目录。
--link myphp-fpm:php: 把 myphp-fpm 的网络并入 nginx，并通过修改 nginx 的 /etc/hosts，把域名 php 映射成 127.0.0.1，让 nginx 通过 php:9000 访问 php-fpm。

接下来我们在 ~/nginx/www 目录下创建 index.php，代码如下：
<?php
echo phpinfo();
?>
浏览器打开 http://127.0.0.1:8083/index.php

3.安装mysql
docker search mysql
docker pull mysql:5.6
docker images |grep mysql
#dockerfile构建
mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf
data目录将映射为mysql容器配置的数据文件存放路径
logs目录将映射为mysql容器的日志目录
conf目录里的配置文件将映射为mysql容器的配置文件
进入创建的mysql目录，创建Dockerfile

命令说明：
-v $PWD/myapp:/usr/src/myapp :将主机中当前目录下的myapp挂载到容器的/usr/src/myapp
-w /usr/src/myapp :指定容器的/usr/src/myapp目录为工作目录
python helloworld.py :使用容器的python命令来执行工作目录中的helloworld.py文件

方法二、通过 Dockerfile 构建
创建Dockerfile

首先，创建目录redis,用于存放后面的相关东西。

runoob@runoob:~$ mkdir -p ~/redis ~/redis/data
data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录

进入创建的redis目录，创建Dockerfile

#!/bin/bash
set -e

# Apache gets grumpy about PID files pre-existing
rm -f /usr/local/apache2/logs/httpd.pid

exec httpd -DFOREGROUND
赋予httpd-foreground文件可执行权限

Docker 容器镜像删除
1.停止所有的container，这样才能够删除其中的images：
docker stop $(docker ps -a -q)
如果想要删除所有container的话再加一个指令：
docker rm $(docker ps -a -q)
2.查看当前有些什么images
docker images
3.删除images，通过image的id来指定删除谁
docker rmi <image id>
想要删除untagged images，也就是那些id为<None>的image的话可以用
docker rmi $(docker images | grep "^<none>" | awk "{print $3}")
要删除全部image的话
docker rmi $(docker images -q)
