前言:

如今咱们对“centoslnmp集成环境搭建”大约比较关怀,朋友们都需要学习一些“centoslnmp集成环境搭建”的相关内容。那么小编也在网摘上汇集了一些关于“centoslnmp集成环境搭建””的相关知识,希望我们能喜欢,朋友们快快来学习一下吧!

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

先在CentOS安装Docker,可参考另外一篇文章:

docker-compose安装
1. curl -L -`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<?phpecho "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: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';
