Docker 环境搭建

服务器：阿里云ESC
系统：CENTOS7.7
安全组：开放-1/-1

//拉取docker镜像

docker pull nginx:latest

//PS：需使用docker cp 进行copy到宿主机

先启动一个镜像，然后copy文件下来

docker run -p 80:80 --name my_nginx nginx

运行成功后 cp目录
需要cp目录：

docker cp my_nginx:/usr/share/nginx/html /nginx 需要将html从文件夹内拿出来
mv /nginx/html /nginx/www   重命名为www
docker cp my_nginx:/etc/nginx/nginx.conf /nginx/nginx.conf
docker cp my_nginx:/etc/nginx/conf.d  /nginx  需要将配置从文件夹内拿出来
//创建nginx容器，并进行守护进行运行
docker run -p 80:80 --name my_nginx -v /nginx/www:/usr/share/nginx/html -v /nginx/nginx.conf:/etc/nginx/nginx.conf -v /nginx/logs:/var/log/nginx -v /nginx/conf.d:/etc/nginx/conf.d -d nginx

停止镜像

docker stop my_nginx

删除多余镜像

docker rm my_nginx

//拉取php7.1镜像

docker pull php:7.1.0-fpm

启动php容器，并挂载至/nginx/www

docker run -p 9000:9000 --name myphp -v /nginx/www/:/usr/share/nginx/html/ --privileged=true -d php:7.1.0-fpm

查看php镜像的ip地址(配置NGINX时需要使用)

docker inspect --format='{{.NetworkSettings.IPAddress}}' myphp
172.17.0.3

docker exec -it myphp /bin/bash #进入php容器
docker-php-source extract    //拉取所有的docker已打包的扩展到/usr/src
进入ext目录
cd /usr/src/php/ext/
ls -l
安装pecl 拓展
apt-get update && apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng-dev

安装mysqli

docker-php-ext-install mysqli

安装reids

pecl install redis  一路回车，不用Y不用N
docker-php-ext-enable 启用redis拓展
ctld+d  退出容器
//重启容器
docker restart myphp
//修改默认nginx配置：(conf/default.conf)

}

推送配置到nginx内

docker cp /nginx/conf.d/default.conf my_nginx:/etc/nginx/conf.d/default.conf
进入容器，重启nginx
docker exec -it my_nginx /bin/bash
service nginx reload
ctrl+d 退出

OK，访问成功

MYSQL未安装
