Dockerfile 方式定制 lnmp 环境

现在容器化技术越来越成熟和流行，比传统的虚拟化技术确实是有很大的优势，所以流行是必然的。今天来实践一把，使用Docker的dockerfile方式定制lnmp环境。

环境配置

操作系统：CentOS Linux release 7.6.1810Docker 版本：19.03.5Nginx 版本：1.15.5PHP 版本：7.2.26MySQL 版本：8.0.18Redis 版本：5.0.5  

创建目录结构

docker目录：//docker相关配置[root@zhangdeTalk data]# tree dockerdocker├── bin│   └── docker-compose-linux.yml //dockerfile.yml├── config│   ├── mysql│   │   └── mysqld.cnf //数据库配置文件│   ├── nginx│   │   ├── conf.d│   │   │   └── default.conf //nginx主要配置文件│   │   └── nginx.conf //nginx基础配置文件│   ├── php│   │   ├── php.ini //php基础配置文件│   │   └── www.conf //php主要配置文件│   └── redis│   └── redis.conf //redis配置文件├── dockerfile│   ├── mysql-8.0.18│   │   └── Dockerfile //mysql的dockerfile│   ├── nginx-1.15.5│   │   └── Dockerfile //nginx的dockerfile│   ├── php-7.2-fpm│   │   └── Dockerfile //php的dockerfile│   └── redis-5.0.5│   └── Dockerfile //redis的dockerfile├── README.en.md└── README.md

www目录：//站点目录[root@zhangdeTalk data]# tree wwwwww└── zhangdetalk_blog_admin├── 1.html└── index.php

logs目录：//日志目录[root@zhangdeTalk data]# tree logslogs├── mysql├── nginx│   ├── access.log│   └── error.log├── php└── redis

mysql目录：//数据库数据目录

redis目录：//数据库数据目录

Docker安装

先在CentOS安装Docker，可参考另外一篇文章：CentOS安装Docker

Nginx配置文件

vim /data/docker/config/nginx/conf.d/default.confserver {         listen 80;         listen [::]:80;         # Add index.php to the list if you are using PHP         index index.html index.htm index.nginx-debian.html index.php;         charset utf-8;         server_name zhangdetalk.com www.zhangdetalk.com;         location ~ \.md$ {             default_type 'text/plain';         }         root /var/www/html/zhangdetalk_blog_admin;//项目目录         location / {                 #try_files $uri $uri/ =404;                 index    index.php index.htm index.html;                 if (!-e $request_filename) {                         rewrite  ^(.*)$  /index.php?s=$1  last;                         break;                 }         }         location ~ \.php$ {                 include fastcgi_params;                 fastcgi_index index.php;                 fastcgi_pass php7:9000;//容器:端口号                 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;         } }

docker-compose安装

1. curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose2. chmod +x /usr/local/bin/docker-compose //设置可执行权限

创建并启动容器

docker-compose -f docker-compose-linux.yml up -d --force-recreate --remove-orphans

容器查看

docker ps

测试

vim /data/www/zhangdetalk_blog_admin/index.php

通过访问站点：http://www.zhangdetalk.com/可以看到显示数据库连接成功，并打印出PHP的相关信息到此步，我们的lnmp环境搭建大功告成！

遇到的问题

1、PHP代码连接数据库，host不能写成127.0.0.1或localhost，需要填写数据库容器名字

2、mysql8连接，连接失败，因为加密方式有变化解决方式：主机登录mysql，修改成旧的加密方式（mysql_native_password），并重置密码 * mysql -uroot -p;* use mysql;* select host,user,plugin from user;* alter user 'root'@'%' identified with mysql_native_password by '123456';
