1.Dockerfile格式
2. Dockerfile指令
3. Build镜像
4. 构建Nginx,PHP,Tomcat基础镜像
前提:上传文件dockerfile .zip和wordpress-4.9.4-zh_CN.tar.gz
[root@localhost first_stage]# unzip dockerfile\ .zip -d Dockerfile/
Archive: dockerfile .zip
inflating: Dockerfile/Dockerfile-nginx
inflating: Dockerfile/Dockerfile-php
inflating: Dockerfile/Dockerfile-tomcat
inflating: Dockerfile/nginx.conf
inflating: Dockerfile/php-fpm.conf
inflating: Dockerfile/php.ini
构建Nginx基础镜像:

5. 快速搭建LNMP网站平台
快速部署LNMP网站平台
1、自定义网络
docker network create lnmp
2、创建Mysql容器
docker run -d \
--name lnmp_mysql \
--net lnmp \
--mount src=mysql-vol,dst=/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
3、创建PHP容器
docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1
4、创建Nginx容器
docker run -d --name lnmp_nginx --net lnmp -p 88:80 \
--mount type=bind,src=$(pwd)/nginx.conf,dst=/usr/local/nginx/conf/nginx.conf --mount src=wwwroot,dst=/wwwroot nginx:v1
5、以wordpress博客为例 https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
实战演练:
创建自定义网络
[root@localhost ~]# docker network create lnmp
e206a2a632cf78430fc6c32d6f50a810c0a8f3ad8ad32287b354cad32de04aac
[root@localhost ~]#
[root@localhost ~]# docker network ls
NETWORK ID NAME DRIVER SCOPE
67d8c68783da bridge bridge local
2b6c8c029f58 host host local
e206a2a632cf lnmp bridge local
fc002cd520b3 none null local
[root@localhost ~]#
查看创建的容器
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@localhost ~]#
查看创建的卷:
[root@localhost ~]# docker volume ls
DRIVER VOLUME NAME
[root@localhost ~]
创建Mysql容器
docker run -d \
--name lnmp_mysql \
--net lnmp \
--mount src=mysql-vol,dst=/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 --character-set-server=utf8
创建PHP容器
docker run -d --name lnmp_php --net lnmp --mount src=wwwroot,dst=/wwwroot php:v1
创建Nginx容器
docker run -d --name lnmp_nginx --net lnmp -p 88:80 \
--mount type=bind,src=$(pwd)/nginx.conf,dst=/usr/local/nginx/conf/nginx.conf --mount src=wwwroot,dst=/wwwroot nginx:v1 #保证当前目录下有nginx.conf文件
挂载后会自动创建本地卷mysql-vol、wwwroot
[root@localhost first_stage]# docker volume ls
DRIVER VOLUME NAME
local mysql-vol
local wwwroot
[root@localhost first_stage]# docker ps -a

[root@localhost first_stage]#
创建静态测试页面:
[root@localhost first_stage]# ls /var/lib/docker/volumes/wwwroot/_data/
[root@localhost first_stage]#
[root@localhost first_stage]# echo "<h2>Hello,World.</h2>">/var/lib/docker/volumes/wwwroot/_data/index.html
浏览器访问:
http://192.168.16.121:88/ 显示内容为:Hello,World.
创建动态测试页面:
[root@localhost first_stage]# echo "<?php phpinfo(); ?>">/var/lib/docker/volumes/wwwroot/_data/test.php
浏览器访问:
http://192.168.16.121:88/test.php 显示内容为:Hello,World.
部署wordpress博客:
[root@localhost first_stage]# wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz
[root@localhost first_stage]# rm -rf /var/lib/docker/volumes/wwwroot/_data/*
[root@localhost first_stage]# tar xf wordpress-4.9.4-zh_CN.tar.gz
[root@localhost first_stage]# mv wordpress/* /var/lib/docker/volumes/wwwroot/_data/
浏览器访问:
http://192.168.16.121:88/index.php 显示内容为:WordPress部署向导.
