启动之前将docker的镜像源改为阿里云的镜像源

vim /etc/docker/daemon.json

#/etc/docker/daemon.json
{
  "registry-mirrors": ["https://ftnejmh3.mirror.aliyuncs.com"]
}

docker 常用命令

#常用命令
docker version #查看版本
systemctl start docker   # 启动docker
systemctl stop docker    # 停止docker
systemctl status docker  # 查看docker状态
systemctl restart docker # 重新启动docker
docker pull nginx  # 拉取下载镜像
docker inspect php | grep "IPAddress"  # 查看容器ip信息
docker images  # 查看本地镜像
docker ps -a  # 查看容器启动情况
docker exec -it 容器id/容器名称 bash  #进入容器内部
docker logs nginx  #查看容器日志
docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm  #创建容器应用
-p 9000:9000 :将容器的9000端口映射到主机的9000端口
-d 后台运行(守护进程)
--name php：将容器命名为php
-v 将主机中当前目录下的www挂载到容器的www目录
docker update --restart=always name #更新容器自动重启

docker搭建nginx容器

docker pull nginx # 拉取下载nginx镜像
mkdir docker # 创建docker目录，管理docker相关配置等文件
cd docker
mkdir nginx # 创建docker目录，管理docker下nginx相关配置文件，用于映射到容器中
cd /docker/nginx
touch default.conf
vim default.conf

#default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;
    root /docker/www/shopby/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /docker/www/shopby/public;
    }

    location ~ \.php$ {
        root /docker/www/shopby/public;
        fastcgi_pass   172.17.0.3:9000;  #映射到php服务端
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

使用nginx镜像创建nginx应用容器

docker run -p 80:80 -d --name nginx -v /docker/nginx/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www --privileged=true nginx

docker搭建php容器

docker pull php:7.4-fpm # 拉取指定下载php7.4版本
docker exec -it php bash
docker-php-ext-install pdo_mysql # 安装php的mysql扩展

使用php镜像创建php应用容器

docker run -p 9000:9000 -d --name php -v /docker/www:/docker/www --privileged=true php:7.4-fpm

docker搭建mysql容器

docker pull mysql # 拉取下载mysql最新版
cd /docker
mkdir mysql
vim mysql/my.cnf

使用mysql镜像创建mysql应用容器，MYSQL_ROOT_PASSWORD=root设置账户密码

docker run -p 3306:3306 -d --name mysql -v /etc/my.cnf:/etc/mysql/my.cnf --privileged=true -e MYSQL_ROOT_PASSWORD=root mysql

docker搭建redis容器

docker pull redis # 拉取下载mysql最新版

遇到问题：Error response from daemon: Get https://registry-1.docker.io/v2/library/ubuntu/manifests/2.04:
解决方式：
第1步：通过dig @114.114.114.114 registry-1.docker.io找到可用IP地址

第二步：修改/etc/hosts强制docker.io相关的域名解析到上面的ip

第三步：保存配置文件，逐个更换ip地址尝试下载镜像，这里是第三个地址成功的。

最后，使用下载成功的redis镜像创建redis应用容器

docker run -p 6379:6379 -d --name redis --privileged=true --requirepass root redis
至此，nginx+mysql+php+redis容器创建完成

redis.conf Maxmemory 4G # 设置最大内存 Maxmemory-policy allkeys-lru # 设置淘汰策略
错误：(error) ERR AUTH called without any password configured for the default user. Are you sure your configuration is correct?
这是设置容器时没有加–requirepass root设置密码参数，root为你要设置的密码
已忘记设置密码的容器，要么重建容器，
要么进入容器
docker exec -it redis bash
redis-cli
config set requirepass root #设置空密码,每次重启密码都会生效，要重复操作，先这样了，没找到配置文件永久设置，待更新…

docker搭建openresty容器

docker pull openresty/openresty # 拉取下载openresty
docker run -p 90:90 -d --name openresty openresty/openresty
docker exec -it openresty bash
cd /etc/nginx/conf.d
docker cp openresty:/etc/nginx/conf.d/default.conf /docker/openresty/conf/default.conf
docker stop openresty
docker rm openresty
docker run -p 90:90 -d --name openresty -v /docker/openresty/conf/default.conf:/etc/nginx/conf.d/default.conf -v /docker/www:/docker/www --privileged=true openresty/openresty
