项目介绍

docker 环境搭建相关代码

git clone https://gitee.com/lvye1221/docker-deploy

【参考资料】docker compose php+mysql+nginx 连载，包含3篇 https://blog.csdn.net/tang05709/article/details/77996246

操作命令：

// 安装库依赖
docker-compose build

// 将会在后台启动并运行所有的容器
docker-compose up -d


// 启动服务器
docker-compose up

mysql

让装好的 mysql 支持远程连接

host为 % 表示不限制ip localhost表示本机使用 plugin非mysql_native_password 则需要修改密码

// 进入 mysql 容器 的命令行
docker exec -it docker_mysql_1 bash


mysql -uroot -p123456

mysql> ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; 
Query OK, 0 rows affected (0.03 sec)

mysql> FLUSH PRIVILEGES;  
Query OK, 0 rows affected (0.00 sec)

【解决办法】 设置 Linux 交换分区

详细参照此文档： https://blog.csdn.net/zstack_org/article/details/53258588

fallocate -l 2G /swapfile
ls -lh /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile


vi /etc/fstab
/swapfile   swap    swap    sw  0   0

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

单独测试 mysql

docker search mysql

docker pull mysql:5.6

docker images |grep mysql


docker run -p 3306:3306 --name mymysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6


docker exec -it mymysql bash

安装vi

apt-get update

apt-get install -y vi apt-get install -y vim

No input file specified.

<?php
echo phpinfo();

docker pull mysql

docker run -d -p 127.0.0.1:3306:3306 –name mysql -v ./testdb:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=”111111” mysql:latest

docker run --name docker_mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d docker.io/mysql restart=always

【解决办法】删除 htdocs 目录下的 .user.ini 文件

连接 mysql 数据库

主机名，是写 docker-compse 中定义的镜像名字 mysql

用户名的权限要给够

docker-compose 密码加密16位改为41位

mysql
select host,user,password from mysql.user;
SET PASSWORD FOR 'root'@'%' = PASSWORD('123456'); 


---------
set @@session.old_passwords=0;
FLUSH PRIVILEGES; 

mysql> select password(“123456”);
