yum安装jdk

**

1、yum -y list java* 查看可安装java版本 选择安装 java-1.8.0-openjdk-accessibility.x86_64 2、yum install -y java-1.8.0-openjdk-devel.x86_64 耐心等待安装完成即可 3、java -version 即可查看当前安装的java版本 4、yum安装的jdk,被安装到哪里去了? 你可以在**/usr/lib/jvm**目录下 5、ls 或者ll 可以查看安装的java相关内容

docker-compose 安装nginx

**

1、下载nginx 镜像 docker pull nginx 下载最新的版本 docker pull nginx:xxx 下载对应的nginx版本 2、创建对应的nginx挂载文件目录

mkdir -p /home/nginx/conf
mkdir -p /home/nginx/log

3、编写docker-compose.yml文件

version: '3.3'
services:
  nginx:
    image: nginx:1.20
    container_name: nginx-warning
    environment:
      TZ: Asia/Shanghai
    restart: always
    ports:
      - 80:80
    volumes:
       - /usr/local/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf
       - /home/gotion-qems/gotion-warning-web/:/usr/share/nginx/html
       - /usr/local/docker/nginx/log:/var/log/nginx
       - /etc/localtime:/etc/localtime:ro

docker-compose 部署nginx和jdk步骤_docker

4、编写对应的ngixn.conf

worker_processes  1;

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

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
	
	#nginx中的proxy_read_timeout指令用于设置代理连接的超时时间。当nginx作为代理服务器转发请求给后端服务器时,如果后端服务器在指定的时间内没有响应,nginx将终止连接并返回错误
    proxy_read_timeout 6000s;
	
    # 限制body大小
    client_max_body_size 100m;

    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;

    upstream server {
        ip_hash;
        server 0.0.0.0:8088;  #网关监听端口
    }

   
    server {
        listen       80;
        server_name  0.0.0.0;  

        location / {
            root   /usr/share/nginx/html/dist;
            try_files $uri $uri/ /index.html;
            index  index.html index.htm;
        }

        location /dev-api/ {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://server/;
        }

	location /prod-api/ {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass http://server/;
        }


        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

5、进入容器命令查看挂载文件

docker exec -it {容器id}|{容器名称} /bin/bash

docker cp 命令:

1、把容器内的文件或目录复制到主机上:docker cp <容器id|容器名称>:容器内的路径 主机的路径
2、把主机上的文件或目录复制到容器内:docker cp 主机的路径 <容器id|容器名称>:容器内的路径
