容器化部署

Nginx

• 前端文件在 html\hmdp 下，挂载到 /usr/share/nginx/html 下

  • 所以要求 nginx.conf ：

  • root /usr/share/nginx/html;

  • index index.html;

  • 反向代理：proxy_pass http://host.docker.internal:8081;

  • listen 80; 因为容器内端口为80

  • 因为 Nginx 监听 80 端口，且 Docker 映射了 80→80，所以访问 http://localhost（80 端口）就能看到页面d

• 对应的logs，nginx.conf 也挂载

docker run -d `--name dianping_nginx `-p 80:80 `-v E:\Projects\03.DianPing\Client\nginx_dianping\conf\nginx.conf:/etc/nginx/nginx.conf `-v E:\Projects\03.DianPing\Client\nginx_dianping\html\hmdp:/usr/share/nginx/html `-v E:\Projects\03.DianPing\Client\nginx_dianping\logs:/var/log/nginx `nginx:latest

}

MySQL

1. 创建容器

docker run -d -p 3306:3306 --privileged=true -v E:\Projects\03.DianPing\mysql\log:/var/log/mysql -v E:\Projects\03.D
ianPing\mysql\data:/var/lib/mysql -v E:\Projects\03.DianPing\mysql\conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=123456 --name dian
ping_mysql mysql:8.0.25

• 解决乱码

[client]
default-character-set = utf8mb4[mysqld]
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci[mysql]
default-character-set = utf8mb4

在Navicat中执行：

SHOW VARIABLES LIKE 'character%';

Redis

docker run -d --name dianping_redis -p 6379:6379 --privileged=true -v E:\Projects\03.DianPing\redis\redis.conf:/etc/redis/redis.conf -v E:\Projects\03.DianPing\redis\data:/data redis

appendonly yes
bind 0.0.0.0
protected-mode no

• MybatisPlusInterceptor

  • 加载了mybatisplus的分页插件

• WebExceptionAdvice

  • @ExceptionHandler(RuntimeException.class),简单的全局异常处理
