docker&&小實戰

使用docker搭建一套簡單的LNMP環境

要求：

• 最終實現能夠訪問：index.php
• 新的網橋IP爲：192.168.0.100/24
• PHP版本爲PHP-7 nginx版本爲NGINX-1.14
• nginx配置文件物理機路徑:/data/nginxconf/nginx.conf,容器配置文件路徑：/etc/nginx/
• 使用nginx新的容器創建一個新的鏡像：鏡像名爲：local-nginx 版本爲：tag-V1

實現

主機操作：

sudo apt-get update
sudo apt-get install     apt-transport-https     ca-certificates     curl     software-properties-common
curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository     "deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu \
    $(lsb_release -cs) \
    stable"
sudo apt-get update
sudo apt-get install docker-ce
curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh --mirror Aliyun
groupadd docker
usermod -aG docker $USER
docker network ls
brctl  show
apt-get install bridge-utils
service docker stop
ip link set dev luckydog down
brctl delbr luckydog
brctl addbr  luckydog
ip addr add 192.168.0.100/24 dev luckydog
ip link set dev luckydog up
ip addr show luckydog
echo 'DOCKER_OPTS="-b=luckydog"' >> /etc/default/docker 
service docker start
service apache2 stop
docker pull ubuntu:18.04
root@ubuntu:~# docker run --name 200312a -p 80:80 -v /data/nginxconf:/etc/nginx -it ubuntu:18.04

容器內操作：

<?php
  		echo "docker_nginx"
?>
vim /etc/nginx/sites-enabled/default

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
        #
