Go to my personal blog https://blognas.hwb0307.com . Welcome to pay attention!

pass Docker series Do you need a personal blog , you've basically decided whether you want to play a WordPress personal blog. Let's take a look at how to install a WordPress personal blog if you need it!

Note: It is currently not recommended to install WordPress for Docker on machines that do not have port 443 open. After testing, it is very difficult to deploy a reverse proxy and ssl certificate for wordpress on a server that does not open port 443/80. This difficulty is mainly due to the security control of wordpress itself. It may be possible to debug nginx, but the current management method based on Nginx proxy manager (non-80/non-443 port) has not been successful yet. Of course, the more important reason is that if your blog address has a port number, it will give people a very informal feeling.

Start the installation below!

test environment

I tested on my own VPS:

uname -a # Linux VM-12-8-ubuntu 5.4.0-42-generic #46-Ubuntu SMP Fri Jul 10 00:24:02 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
docker --version # Docker version 20.10.5, build 55c4c88
docker-compose --version # docker-compose version 1.28.6, build 5db8d86f

Preparation

# Please modify the working directory as needed
work=~/docker/wordpress && mkdir -p $work/{db,app} && cd $work

# Turn on the firewall and modify as needed
sudo ufw allow 4145/tcp comment 'wordpress' && sudo ufw reload

# Pull the image ahead of time
docker pull mysql:5.7
docker pull wordpress:latest

configure yml file

New file docker-compose.yml:

vim $work/docker-compose.yml

Add the following:

---
version: '3.0'

services:
  db:
    image: mysql:5.7
    restart: unless-stopped
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword # Modify as needed

    networks:
      - default
      
  app:
    image: wordpress:latest
    restart: unless-stopped
    ports:
      - 4145:80  # Modify as needed. Consistent with firewall open ports.
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_NAME: wordpress
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: yourpassword # Modify as needed

networks:
  default:
    name: wordpress

direct online service

# Start the service
cd $work && docker-compose up -d 

ddns-go & NPM

Set up the dynamic domain name resolution of blog.exampledomain.com in ddns-go or domain name hosting background (pointing to the ip of nas).

Set up a reverse proxy in NPM. As shown below:

After the setup is complete, log in directly: https://blog.exampledomain.com

Similar to:

Finally it worked! You can log in directly by pressing login:

The default background looks like this:

summary

Installing WordPress via Docker in a VPS is really easy. There are no special settings.

Of course, if you use a non-443 port machine, you will be more fortunate (~￣▽￣)~

WordPress has been successfully installed here. Later we will talk about how to set it up!
