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
<code>操作系统：CentOS Linux release 7.6.1810
Docker 版本：19.03.5
Nginx 版本：1.15.5
PHP 版本：7.2.26
MySQL 版本：8.0.18
Redis 版本：5.0.5 /<code>
创建目录结构
<code>docker目录：//docker相关配置

Docker安装
先在CentOS安装Docker，可参考另外一篇文章：

dockerfile.yml配置

Nginx配置文件
<code>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; } }/<code>
docker-compose安装
<code>1. curl -L https://get.daocloud.io/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
2. chmod +x /usr/local/bin/docker-compose //设置可执行权限/<code>
创建并启动容器
<code>docker-compose -f docker-compose-linux.yml up -d --force-recreate --remove-orphans/<code>
容器查看
<code>docker ps/<code>
测试
<code>vim /data/www/zhangdetalk_blog_admin/index.php
echo "Hello World";
$conn = mysqli_connect('数据库容器名字','dbuser','dbpw');
if($conn){
echo '数据库连接成功！';
}else{
echo '数据库连接失败！';
}
phpinfo();
?>/<code>
<code>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！/<code>
github源码
<code>相关的源码下载地址：https://github.com/zhangdejian/docker_lnmp.git/<code>
遇到的问题
<code>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/<code>
<code>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';/<code>
