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。
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

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

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
docker-compose -f docker-compose-linux.yml up -d --force-recreate --remove-orphans
docker ps
vim /data/www/zhangdetalk_blog_admin/index.php <?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(); ?>
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!

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‘;
