Halo安装

Halo是一个基于Java开发的开源内容管理系统，它可以用来创建和管理个人博客或网站。它具有许多功能，如用户认证、多语言支持、主题定制等。

以下为ubuntu 22.04 LTS 上安装halo的过程。

安装halo

前提是你已经安装好了docker，请参考ubuntu docker安装。在docker基础上安装halo，执行以下命令创建halo文件：

mkdir ~/halo && cd ~/halo

创建docker-compose.yaml 文件，这里我选择mysql作为数据库：

vi docker-compose.yaml

version: "3"

services:
  halo:
    image: halohub/halo:2.13
    container_name: halo
    restart: on-failure:3
    depends_on:
      halodb:
        condition: service_healthy
    networks:
      halo_network:
    volumes:
      - ./halo2:/root/.halo2
    ports:
      - "8090:8090"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8090/actuator/health/readiness"]
      interval: 30s
      timeout: 5s
      retries: 5
      start_period: 30s
    command:
      - --spring.r2dbc.url=r2dbc:pool:mysql://halodb:3306/halo
      - --spring.r2dbc.username=root
      # MySQL 的密码，请保证与下方 MYSQL_ROOT_PASSWORD 的变量值一致。
      - --spring.r2dbc.password=o#DwN&JSa56
      - --spring.sql.init.platform=mysql
      # 外部访问地址，请根据实际需要修改
      - --halo.external-url=http://localhost:8090/

  halodb:
    image: mysql:8.1.0
    container_name: halodb
    restart: on-failure:3
    networks:
      halo_network:
    command: 
      - --default-authentication-plugin=caching_sha2_password
      - --character-set-server=utf8mb4
      - --collation-server=utf8mb4_general_ci
      - --explicit_defaults_for_timestamp=true
    volumes:
      - ./mysql:/var/lib/mysql
      - ./mysqlBackup:/data/mysqlBackup
    ports:
      - "3306:3306"
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-h", "127.0.0.1", "--silent"]
      interval: 3s
      retries: 5
      start_period: 30s
    environment:
      # 请修改此密码，并对应修改上方 Halo 服务的 SPRING_R2DBC_PASSWORD 变量值
      - MYSQL_ROOT_PASSWORD=o#DwN&JSa56
      - MYSQL_DATABASE=halo

networks:
  halo_network:

启动halo：

docker-compose up -d

用浏览器访问http://你的IP:8090/console 进入halo初始化并设置相关信息

nginx代理

没有安装nginx的安装命令：

 apt install nginx

安装好后修改配置vi /etc/nginx/nginx.conf，以下配置将http转htpps，部署证书路径，将443端口转到8090端口上：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
	worker_connections 1024;
}

http {
	sendfile on;
	tcp_nopush on;
	types_hash_max_size 2048;
	include /etc/nginx/mime.types;
	default_type application/octet-stream;
	ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
	ssl_prefer_server_ciphers on;
	access_log /var/log/nginx/access.log;
	error_log /var/log/nginx/error.log;
	gzip on;

  #个人博客
  server {
    listen 80;
    server_name 你的域名;
    rewrite ^(.*)$ https://${server_name}$1 permanent; 
  }
  server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    ssl_certificate "你的证书绝对路径";
    ssl_certificate_key "你的证书绝对路径key";
    server_name 你的域名;
    client_max_body_size 1024m;
    
    location / {
        proxy_pass http://127.0.0.1:8090;
        proxy_set_header Host $host;
        # real-ip
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header REMOTE-HOST $remote_addr;
        # websocket
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_read_timeout 86400;
    }
  }
	include /etc/nginx/conf.d/*.conf;
	include /etc/nginx/sites-enabled/*;
}

在浏览器访问 https://你的域名 就可以访问到halo的首页了。
