基于边缘检测算法检测视频中文字

基于 Vue+Spring Cloud 前后端服务的云部署

系统环境

• 基础环境

centos 8 # 操作系统
JDK 1.8 # java
yum -y install java
git
yum install git

前端打包

• 1.打包指令

npm run build

• 2.文件上传

• 使用 FTP 工具上传dist文件

后端打包

• 1.Maven 打包

mvn clean package #or mvn install 只需在父服务中运行

• 2.jar 包上传

• 使用 FTP 上传 jar 包

• 3.jar 包运行

nohub java -jar rs_shop_service.jar & 1 &out.log

云服务器部署

• 1.基础镜像配置

• 镜像源设置

mkdir /etc/yum.repos.d.bak
mv /etc/yum.repos.d/* /etc/yum.repos.d.bak/
ll /etc/yum.repos.d/
ll /etc/yum.repos.d.bak/
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's/releasever\//releasever-stream\//g' /etc/yum.repos.d/CentOS-Base.repo

• 缓存清除与元数据重建

yum clean all
yum makecache

• 2.Docker 安装与使用

• 更新 yum 源

yum -y update

• 安装

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl start docker
systemctl enable docker

• 3.基础镜像安装与使用

• mysql

docker pull mysql # 镜像拉取
docker images # 查看镜像
docker run --name testmysql -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=smx0920 mysqlimagesname #运行
docker ps -a

• redis

docker pull redis
docker images
docker run -p 6379:6379 -v $PWD/data:/data  -d redis redis-server --appendonly yes
docker ps -a

• nginx

docker pull nginx
docker images
mkdir -p /data/nginx/conf
mkdir -p /data/nginx/conf.d
mkdir -p /data/nginx/html
mkdir -p /data/nginx/logs
docker run --name mynginx -d -p 80:80 -v /data/nginx/html:/usr/share/nginx/html -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf -v /data/nginx/logs:/var/log/nginx nginx
docker ps -a

• 4.基础镜像配置

• mysql

mysql需做如下配置

docker exec -it mysql bash
mysql -u root -p
# 输入密码回车
```
`对数据库做如下配置`
```sql
alter user 'root'@'%' identified with mysql_native_password by 'smx0920';
flush privileges;
```
```sh
exit
docker restart mysql
docker ps -a

• redis
  运行完后做如下测试：

curl -L 127.0.0.1:6379

• nginx

nginx.conf 配置

user nginx;
worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid    /var/run/nginx.pid;

events {
  worker_connections 1024;
}

http {
  include    /etc/nginx/mime.types;
  default_type application/octet-stream;

  log_format main '$remote_addr - $remote_user [$time_local] "$request" '
    '$status $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';

  access_log /var/log/nginx/access.log main;

  sendfile    on;
  #tcp_nopush   on;

  keepalive_timeout 65;

  #gzip on;

  include /etc/nginx/conf.d/*.conf;
}

default.conf 配置

server {
  listen    6666;
  server_name localhost;

  #charset koi8-r;
  #access_log /var/log/nginx/host.access.log main;

  location / {
    root  /usr/share/nginx/html;
    index 1.html;
  }

  #error_page 404/404.html;

  # redirect server error pages to the static page /50x.html
  #
  error_page  500 502 503 504 /50x.html;
  location = /50x.html {
    root  /usr/share/nginx/html;
  }

  location /api/ {
    proxy_pass http://localhost:10000/shop #端口代理转发
  }
  # proxy the PHP scripts to Apache listening on 127.0.0.1:80
  #
  #location ~ .php$ {
  #  proxy_pass  http://127.0.0.1;
  #}

  # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
  #
  #location ~ .php$ {
  #  root      html;
  #  fastcgi_pass  127.0.0.1:9000;
  #  fastcgi_index index.php;
  #  fastcgi_param script_FILENAME /scripts$fastcgi_script_name;
  #  include    fastcgi_params;
  #}

  # deny access to .htaccess files, if Apache's document root
  # concurs with nginx's one
  #
  #location ~ /.ht {
  #  deny all;
  #}
}

• 配置完成后，重启容器

docker restart containerid

• 或者进入容器重启 nginx 服务

docker exec -it nginx  bash
nginx -s reload
nginx -t

• 5.服务搭建与测试

最终测试

• 1.前端页面测试

curl -L http://localhost:6666

• 2.后端接口测试

curl -L http://localhost:10000/api/shop/test
