使用docker-compose编排lnmp（dockerfile）完成wordpress

1、服务器环境

容器	操作系统	IP地址	主要软件
nginx	CentOS 7.9 x86_64	172.20.0.10	Docker-Nginx
mysql	CentOS 7.9 x86_64	172.20.0.20	Docker-Mysql
php	CentOS 7.9 x86_64	172.20.0.30	Docker-php

2、Docker、Docker-Compose环境安装

[root@liuyanfen13 ~]#systemctl disable --now firewalld
[root@liuyanfen13 ~]#setenforce 0
#关闭防火墙和核心防护

2.1 安装Docker环境

[root@liuyanfen13 ~]#yum install -y yum-utils device-mapper-persistent-data lvm2
#安装依赖包
[root@liuyanfen13 ~]#yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#设置阿里云镜像源
[root@liuyanfen13 ~]#yum install -y docker-ce docker-ce-cli containerd.io
#安装Docker-CE（社区版）
[root@liuyanfen13 ~]#systemctl enable --now docker.service
#开机自启并立即启动
[root@liuyanfen13 ~]#systemctl status docker.service
#查看状态

2.2 安装Docker-Compose

[root@liuyanfen13 compose_lnmp]#curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
#下载安装
[root@liuyanfen13 compose_lnmp]#chmod +x /usr/local/bin/docker-compose
#添加权限

需要的文件和安装包

[root@liuyanfen13 compose_lnmp]#pwd
/opt/compose_lnmp
[root@liuyanfen13 compose_lnmp]#ls
docker-compose.yml  mysql  nginx  php
[root@liuyanfen13 compose_lnmp]#cd mysql/
[root@liuyanfen13 mysql]#ls
Dockerfile  my.cnf  mysql-boost-5.7.20.tar.gz
[root@liuyanfen13 mysql]#cd ../nginx/
[root@liuyanfen13 nginx]#ls

    ports:
      - 80:80
    networks:
      vae:
        ipv4_address: 172.20.0.10
    volumes:
      - ./nginx/nginx.conf:/usr/local/nginx/nginx.conf
      - ./nginx/html:/usr/local/nginx/html
      #共享目录（将宿主机的目录挂载到容器）
  mysql:
    container_name: mysql
    hostname: mysql
    build:
      context: ./mysql
      dockerfile: Dockerfile
    ports:
      - 3306:3306
    networks:
      vae:
        ipv4_address: 172.20.0.20

      dockerfile: Dockerfile
    ports:
      - 9000:9000
    networks:
      vae:
        ipv4_address: 172.20.0.30
    volumes_from:
    #数据卷
      - nginx
      - mysql
    depends_on:
    #依赖关系，php容器在nginx、mysql容器之后启动
      - nginx
      - mysql
networks:
#设置自定义网络
  vae:
    driver: bridge
    ipam:
      config:
        - subnet: 172.20.0.0/16

7、生成镜像容器

[root@liuyanfen13 compose_lnmp]#docker-compose -f docker-compose.yml up -d
#生成镜像容器
[root@liuyanfen13 compose_lnmp]#docker images

#显示所有容器

8、验证登录

http://192.168.10.13/wordpress/index.php
#浏览器访问验证

9、启动wordpress服务

9.1 mysql授权

[root@liuyanfen13 nginx]#docker exec -it mysql bash
#进入mysql容器
[root@mysql mysql-5.7.20]# mysql -u root -p
