Centos 下载使用 Docker

1、更新update到最新的版本

yum update

2、卸载老版本docker

yum remove docker docker-common docker-selinux docker-engine

3、安装需要的软件包

yum install -y yum-utils device-mapper-persistent-data lvm2

4、设置yum源

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

5、查看docker版本/安装docker

yum list docker-ce --showduplicates|sort -r

yum install docker-ce-18.03.1.ce -y

6、启动docker / 加入开机自启

systemctl start docker

systemctl enable docker

7、配置国内镜像

vi /etc/docker/daemon.json

{

"registry-mirrors": ["http://hub-mirror.c.163.com"]

}

8、查看/保存/删除/载入 [save是保存镜像 export是保存容器]

docker images

docker save REPOSITORY > abc.tar

eg:docker save php-fpm > php-fpm.tar

docker rmi IMAGE ID

docker load < php-fpm.tar

搭建mysql、nginx、php环境

docker network ls / rm name

docker network create --subnet=192.168.1.1/24 mysql-net

docker network create --subnet=192.168.2.1/24 nginx-net

docker network create --subnet=192.168.3.1/24 php-net

docker ps -a --no-trunc 【不省略】

docker run -itd -p 3306:3306 --name mysql -v /data/mysql/data:/var/lib/mysql -v /data/mysql/etc:/etc/mysql -e MYSQL_ROOT_PASSWORD=Andrewhsu123 --net mysql-net mysql

这/data/mysql/etc个文件夹下面的my.cnf文件会默认加载,所以需要自己手写一个my.cnf

docker run -itd -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=Andrewhsu123 --net mysql-net mysql

docker cp mysql:/etc/mysql /data/mysql/etc1

docker exec -it mysql bash

docker start mysql

docker exec -it mysql mysql -uroot -p

docker run -itd -p 80:80 -p 433:433 --name nginx --net nginx-net nginx

docker run -itd -p 80:80 -p 433:433 --name nginx -v /data/www:/usr/share/nginx/html -v /data/nginx/logs:/var/log/nginx--net nginx-net nginx

docker cp nginx:/etc/nginx/nginx.conf /data/nginx/conf/nginx.conf

docker cp nginx:/etc/nginx/conf.d /data/nginx/conf/conf.d

-v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf

-v /data/nginx/conf/conf.d:/etc/nginx/conf.d

docker run -itd -p 80:80 -p 443:443 --name nginx -v /data/www:/usr/share/nginx/html -v /data/nginx/logs:/var/log/nginx -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/conf/conf.d:/etc/nginx/conf.d -v /data/nginx/ssl:/etc/nginx/ssl --net nginx-net nginx

-p 80:80：将容器的 80 端口映射到主机的 80 端口。

-p 443:443：将容器的 443 端口映射到主机的 443 端口。（可选项，配置https时加上）

--name nginx：将容器命名为 nginx。

-v /opt/nginx/html:/usr/share/nginx/html：将我们自己创建的 html目录挂载到容器的 /usr/share/nginx/html。

-v /opt/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 /opt/nginx/logs:/var/log/nginx：将我们自己创建的 logs 挂载到容器的 /var/log/nginx。

-v /opt/nginx/conf/conf.d:/etc/nginx/conf.d: 将conf.d目录挂载，后面进行二级域名反向代理映射端口时用，不配做这个后面配置不生效

-v /opt/nginx/ssl:/etc/nginx/ssl：将我们自己创建的 ssl目录挂载到容器的 /etc/nginx/ssl，此项为可选项，要使用https证书时加上。

docker run -itd -p 9000:9000 --name php7 -v /data/www:/www php
