Docker 安装LNMP环境

yum install docker
# 启动并加入开机启动
sudo systemctl start docker
sudo systemctl enable docker

# 拉取管方镜像
docker pull nginx
# 创建并运行容器，映射端口为80
docker run --name nginx -p 80:80 -d nginx
# 访问IP，nginx能够正常运行

# 拉取管方镜像，这里拉取的是php7，根据自己所需拉取
docker pull phpdockerio/php7-fpm

# 进入nginx容器
docker exec -it nginx bash
# 查看nginx配置文件
cat /etc/nginx/conf.d/default.conf -n
# 找到location / {
#     root    /usr/share/nginx/html;#这是nginx默认运行路径
#     index   index.html index.html;
# }

docker run --name phpfpm -d 9000:9000 -v /var/www/html:/usr/share/nginx/html -d phpdockerio/php7-fpm

# 进入php容器
docker exec -it phpfpm bash
# 进入运行目录
cd /usr/share/nginx/html
# vim 创建index2.php
# 因为docker没有安装vim，此时运行
apt-get update
apt-get install vim

docker pull mysql
# 创建并运行mysql容器
docker run --name mysql -p 3306:3306 -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql

docker ps  #查看容器id
docker cp linux文件 容器id:容器路径

#linux中查找php.ini
php -i | grep 'php.ini'
#docker 因配置文件出错无法进入容器内解决办法
#将容器配置文件复制到服务器上
1.docker cp mynginx:/etc/nginx/conf.d/default.conf /users/nginx/default.conf
#修改后再写回容器中
2.docker cp /users/nginx/default.conf mynginx:/etc/nginx/conf.d/default.conf
