阿里云Ubuntu18安装Docker环境，搭建WordPress

1、安装docker和docker-compose

<span class="token function">apt-get</span> update <span class="token function">apt-get</span> upgrade <span class="token function">apt-get</span> <span class="token function">install</span> vim <span class="token function">sudo</span> apt <span class="token function">install</span> docker.io systemctl start docker systemctl <span class="token function">enable</span> docker docker --version <span class="token function">useradd</span> -m -s /bin/bash 账户名 <span class="token function">passwd</span> 密码 apt <span class="token function">install</span> docker-compose docker-compose --version  reboot/shutdown -r now  docker <span class="token function">exec</span> -it 9fbe362214a6<span class="token punctuation">(</span>容器Id<span class="token punctuation">)</span> /bin/bash 
<span class="token function">apt-get</span> update <span class="token function">apt-get</span> upgrade <span class="token function">apt-get</span> <span class="token function">install</span> vim <span class="token function">sudo</span> apt <span class="token function">install</span> docker.io systemctl start docker systemctl <span class="token function">enable</span> docker docker --version <span class="token function">useradd</span> -m -s /bin/bash 账户名 <span class="token function">passwd</span> 密码 apt <span class="token function">install</span> docker-compose docker-compose --version  reboot/shutdown -r now  docker <span class="token function">exec</span> -it 9fbe362214a6<span class="token punctuation">(</span>容器Id<span class="token punctuation">)</span> /bin/bash 
apt-get update apt-get upgrade apt-get install vim sudo apt install docker.io systemctl start docker systemctl enable docker docker --version useradd -m -s /bin/bash 账户名 passwd 密码 apt install docker-compose docker-compose --version  reboot/shutdown -r now  docker exec -it 9fbe362214a6(容器Id) /bin/bash 

2、更改镜像地址

  vim /etc/docker/daemon.json systemctl restart docker 
  vim /etc/docker/daemon.json systemctl restart docker 
  vim /etc/docker/daemon.json systemctl restart docker 

3、编写docker-compose

 <span class="token function">mkdir</span> my_wordpress <span class="token function">cd</span> my_wordpress vim docker-compose.yml 
 <span class="token function">mkdir</span> my_wordpress <span class="token function">cd</span> my_wordpress vim docker-compose.yml 
 mkdir my_wordpress cd my_wordpress vim docker-compose.yml 

version: <span class="token string">'3.3'</span> services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - <span class="token string">"8000:80"</span> restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress WORDPRESS_DB_NAME: wordpress volumes: db_data: <span class="token punctuation">{<!-- --></span><span class="token punctuation">}</span> 
version: <span class="token string">'3.3'</span> services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - <span class="token string">"8000:80"</span> restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress WORDPRESS_DB_NAME: wordpress volumes: db_data: <span class="token punctuation">{<!-- --></span><span class="token punctuation">}</span> 
version: '3.3' services: db: image: mysql:5.7 volumes: - db_data:/var/lib/mysql restart: always environment: MYSQL_ROOT_PASSWORD: somewordpress MYSQL_DATABASE: wordpress MYSQL_USER: wordpress MYSQL_PASSWORD: wordpress wordpress: depends_on: - db image: wordpress:latest ports: - "8000:80" restart: always environment: WORDPRESS_DB_HOST: db:3306 WORDPRESS_DB_USER: wordpress WORDPRESS_DB_PASSWORD: wordpress WORDPRESS_DB_NAME: wordpress volumes: db_data: {} 

启动容器

docker-compose up -d 
docker-compose up -d 
docker-compose up -d 

4、修改文件上传限制(默认2M)

 https://blog.csdn.net/j84491135/article/details/105977073 docker <span class="token function">exec</span> -it 容器名/容器ID /bin/bash <span class="token function">cp</span> /usr/local/etc/php/php.ini-production /usr/local/etc/php/php.ini vim /usr/local/etc/php/php.ini 
 https://blog.csdn.net/j84491135/article/details/105977073 docker <span class="token function">exec</span> -it 容器名/容器ID /bin/bash <span class="token function">cp</span> /usr/local/etc/php/php.ini-production /usr/local/etc/php/php.ini vim /usr/local/etc/php/php.ini 
 https://blog.csdn.net/j84491135/article/details/105977073 docker exec -it 容器名/容器ID /bin/bash cp /usr/local/etc/php/php.ini-production /usr/local/etc/php/php.ini vim /usr/local/etc/php/php.ini 

重点注意下面三个参数

upload_max_filesize <span class="token operator">=</span> 200M  post_max_size <span class="token operator">=</span> 250M  memory_limit <span class="token operator">=</span> 500M  
upload_max_filesize <span class="token operator">=</span> 200M  post_max_size <span class="token operator">=</span> 250M  memory_limit <span class="token operator">=</span> 500M  
upload_max_filesize = 200M  post_max_size = 250M  memory_limit = 500M  

然后重启容器

docker-compose stop docker-compose up -d 
docker-compose stop docker-compose up -d 
docker-compose stop docker-compose up -d 

最后：
云服务器Docker容器Mysql无法被远程访问原因汇总
