用容器构建wordpress项目

bash 复制代码

#准备两个镜像
#数据库和centos
docker pull mysql:5.7
docker pull centos:7
#创建一个wordpress文件夹，在wordpress文件里面写一个Dockerfile文件
vim Dockerfile

FROM centos:7 #基于centos环境

RUN yum -y install epel-release ;\ #安装扩展源
    yum -y install nginx ;\ #安装gnix和php
    yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm ; \
    yum install php80-php-xsl php80-php php80-php-cli php80-php-devel php80-php-gd php80-php-pdo php80-php-mysql php80-php-fpm -y

COPY nginx.conf /etc/nginx/nginx.conf #把nginx的配置文件拷贝的镜像里面
COPY ./start.sh / #拷贝启动php和nginx的脚本到容器里面
ADD ./wordpress-6.5.3-zh_CN.tar.gz /usr/share/nginx/  #拷贝nginx的项目到nginx的发布目录下,不用解压ADD有自动解压的功能
EXPOSE 80 #容器暴露的端口
VOLUME /usr/share/nginx/wordpress 

CMD ["sh","/start.sh"]

#写完Dockerfile文件后，构建镜像
docker build -t wordpress-centos:1.0 .

启动脚本文件

bash 复制代码

#!/bin/bash

chmod 777 -R /usr/share/nginx/wordpress

/opt/remi/php80/root/usr/sbin/php-fpm && \
echo "php启动成功"
nginx && \
echo "nginx启动成功"
tail -f /var/log/nginx/*

启动容器

bash 复制代码

#启动mysql容器
docker run -itd -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=wordpress mysql:5.7 #在启动容器的时候创建wordpress库和用户密码
#启动wordpress-centos镜像
docker run -it -p 80:80 --link=gracious_raman:mysql.host wordpress-cenos:3.0 #--link是用来连接两个容器，:前面是源容器，后面是接受容器 -p 是做端口映射

测试

用docker compose编排部署wordpress

bash 复制代码

#创建一个wordpress-compose目录，把前面的wordpress目录移动到此目录下
#在wordpress-compose下创建一个docker-compose.yml文件
vim docker-compose.yml

services:

  centos:       #要用到的镜像
    hostname: wordpress-centos #容器里面的主机名
    container_name: wordpress-centos #容器名
    build:  #构建
        context: ./wordpress  #dockerfile文件在当前目录的wordpress目录下
    ports:   #暴露的端口
       - "80:80"  
       - "443:443"
    links:     #主节解析
       - "database:mysql.host"
    depends_on: #这个镜像的启动依赖于
       - database

        
  database:  #直接使用的镜像，不用构建
       image: mysql:5.7
       hostname: wordpress-database
       container_name: wordpress-database
       environment:
          - MYSQL_ROOT_PASSWORD=123456
          - MYSQL_DATABASE=wordpress
       volumes:
          - /opt/wordpress-data:/var/lib/mysql:rw
          
docker compose up #构建启动容器

DATABASE=wordpress

volumes:

/opt/wordpress-data:/var/lib/mysql:rw

docker compose up #构建启动容器
