聊天关于websocket的配置

1、nginx配置文件

server下面配置如下：

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
    proxy_read_timeout 86400s;

再添加接口、管理后台、socket的相关配置

location /myChat/ {  
    proxy_redirect off;
    proxy_pass http://127.0.0.1:8009;   
    proxy_connect_timeout 3000s; #配置点1 
    proxy_read_timeout 86400s; #配置点2,如果没效,可以考虑这个时间配置长一点 
    proxy_send_timeout 3600s; #配置点3 
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
    proxy_set_header REMOTE-HOST $remote_addr;
    #proxy_bind $remote_addr transparent;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    # proxy_set_header Connection $connection_upgrade;
    proxy_set_header Connection "Upgrade";
    # rewrite /myChat/(.*) /$1 break;
    proxy_buffer_size          4k;
    proxy_buffers              4 32k;
    proxy_busy_buffers_size    64k;
    proxy_temp_file_write_size 64k;
    client_max_body_size 50m;

}
location /app/{
    proxy_pass http://127.0.0.1:8009/app/;
    proxy_set_header Host $host;
    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;

    #缓存相关配置
    #proxy_cache cache_one;
    #proxy_cache_key $host$request_uri$is_args$args;
    #proxy_cache_valid 200 304 301 302 1h;

    #持久化连接相关配置
    proxy_connect_timeout 3000s;
    proxy_read_timeout 86400s;
    proxy_send_timeout 3000s;
    #proxy_http_version 1.1;
    #proxy_set_header Upgrade $http_upgrade;
    #proxy_set_header Connection "upgrade";

    add_header X-Cache $upstream_cache_status;

    #expires 12h;
}
location /api/admin/ {
    proxy_pass http://127.0.0.1:8009/admin/;
    proxy_set_header Host $host;
    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;

    #缓存相关配置
    #proxy_cache cache_one;
    #proxy_cache_key $host$request_uri$is_args$args;
    #proxy_cache_valid 200 304 301 302 1h;

    #持久化连接相关配置
    proxy_connect_timeout 3000s;
    proxy_read_timeout 86400s;
    proxy_send_timeout 3000s;
    #proxy_http_version 1.1;
    #proxy_set_header Upgrade $http_upgrade;
    #proxy_set_header Connection "upgrade";

    add_header X-Cache $upstream_cache_status;

    #expires 12h;
}

2、安装相关软件rabbitmq

安装相关依赖-Erlang

    curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash

1-2、下载erlang包
    wget --content-disposition https://packagecloud.io/rabbitmq/erlang/packages/el/8/erlang-25.2-1.el8.x86_64.rpm/download.rpm?distro_version_id=205

1-3、安装erlang包
    yum install erlang-25.2-1.el8.x86_64.rpm

安装RabbitMQ及配置

1-1、安装存储库
    curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash
1-2、下载erlang包
    wget --content-disposition "https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/9/rabbitmq-server-3.13.4-1.el8.noarch.rpm/download.rpm?distro_version_id=240"

配置RabbitMQ

设置开机自启动
    systemctl enable rabbitmq-server
启动
    service rabbitmq-server start
查看状态
    service rabbitmq-server status
停止
    service rabbitmq-server stop
启用Management Plugin

设置用户及授权

• 新建一个用户并设置密码

   rabbitmqctl add_user 用户名 '密码'
  

• 给这个用户分配管理员权限

   rabbitmqctl set_user_tags 用户名 administrator
  

设置配置文件

(一般在/etc/rabbitmq/conf.d/下面，没有的话自行创建，否则连接不上)

1、查看rabbitmq详细信息及配置文件位置

rabbitmqctl status

2、"/etc/rabbitmq/conf.d/10-defaults.conf"文件内容如下：

## DEFAULT SETTINGS ARE NOT MEANT TO BE TAKEN STRAIGHT INTO PRODUCTION
## see https://www.rabbitmq.com/configure.html for further information
## on configuring RabbitMQ

## allow access to the guest user from anywhere on the network
## https://www.rabbitmq.com/access-control.html#loopback-users
## https://www.rabbitmq.com/production-checklist.html#users
loopback_users.guest = false

## Send all logs to stdout/TTY. Necessary to see logs when running via
## a container
log.console = true

3、"/etc/rabbitmq/conf.d/20-management_agent.disable_metrics_collector.conf"文件内容如下：

# Enable Prometheus-style metrics by default (https://github.com/docker-library/rabbitmq/issues/419)
management_agent.disable_metrics_collector = true
