【打工日常】云原生之搭建私有化web在线聊天软件LumenIM

一、LumenIM介绍

1.LumenIM简介

Lumen IM 是一个网页版在线聊天项目，前端使用 Naive UI + Vue3，后端采用 GO 开发。

2.LumenIM功能

基于 WebSocket 服务做消息即时推送
支持私聊及群聊
支持多种聊天消息类型例如:文本、代码块、图片及其它类型文件，并支持文件下载
支持聊天消息撤回、删除(批量删除)、转发消息(逐条转发、合并转发)、群禁言
支持编写个人笔记、支持笔记分享(好友或群)。

3.LumenIM项目地址

前端：https://gitee.com/gzydong/LumenIM
后端：https://gitee.com/gzydong/go-chat

二、本次实践介绍

1. 本次实践简介

a.本次实践部署环境为个人腾讯云的测试环境，若是生产环境请谨慎部署；

b.本次实践使用了mysql、redis、nginx以及前后端的开源包进行启动测试。

2. 本地环境规划

本次实践环境规划：通过docker启动nginx、mysql、redis，以及本地启动前后端

三、检查本地Docker环境

1. 检查本地Docker版本

检查Docker版本：docker version

2. 检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行。

systemctl status docker

四、部署过程

```
1.下载前后端程序
# 前端部分：
#到opt目录下创建该程序的存放路径
cd /opt
mkdir LumenIm
cd LumenIm
git clone https://gitee.com/gzydong/LumenIM.git
git clone https://github.com/gzydong/go-chat.git
2.下载下来后，要部署编译，先前端：
yarn install
#需要先安装yarn
yum install npm
npm install -g yarn
3.安装依赖包后，构建生产环境配置
yarn build
4.ll -a查看LumenIm全部的配置文件，找到.env.electron，接口的地址写上，具体的ip根据你自己的服务器的公网地址去写。
ENV = 'production'
VITE_BASE=./
VITE_ROUTER_MODE=hash
VITE_BASE_API=http://43.138.153.157:9503
VITE_SOCKET_API=ws://43.138.153.157:9504
5.然后启动本地开发环境桌面客户端
yarn electron:dev
6.mysql、redis、nginx部署，我这边是直接docker compose启动的
version: '3'
services:
redis:
image: 'redis:latest'
volumes:
- '/opt/redis/data:/data'
- '/opt/redis/conf/redis.conf:/etc/redis/redis.conf'
privileged: true
container_name: redis
ports:
- '6379:6379'
restart: always
mysql_dba:
image: 'mysql:latest'
environment:
- MYSQL_ROOT_PASSWORD=111111
volumes:
- '/etc/localtime:/etc/localtime:ro'
- '/opt/mysql/conf:/etc/mysql/conf.d'
- '/opt/mysql/data:/var/lib/mysql'
- '/opt/mysql/log:/var/log/mysql'
privileged: true
restart: always
container_name: mysql_dba
ports:
- '3306:3306'
nginx:
image: 'nginx:latest'
restart: always
volumes:
- '/etc/localtime:/etc/localtime:ro'
- '/opt/LumenIm/LumenIM/dist:/opt/LumenIm/LumenIM/dist'
- '/opt/nginx/nginx.conf:/etc/nginx/nginx.conf'
ports:
- '80:80'
container_name: nginx
以上具体每个容器的路径自己设定
####nginx配置文件如下：
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
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;
server {
listen 80;
server_name localhost;
root /opt/LumenIm/LumenIM/dist;
index index.html;
location / {
try_files $uri $uri/ /index.html;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
expires 7d;
}
location ~ .*\.(js|css)?$ {
expires 7d;
}
}
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
#include /etc/nginx/conf.d/*.conf;
}
7.后端部署：
拷贝项目根目录下 config.example.yaml 文件为 config.yaml 并正确配置相关参数
cp config.example.yaml config.yaml
我这边的配置如下：
# 项目配置信息
app:
env: dev
debug: false
juhe_key: "xxxxxxx"
admin_email:
-
public_key: |
-----BEGIN PUBLIC KEY-----
xxxxxxx
-----END PUBLIC KEY-----
private_key: |
-----BEGIN RSA PRIVATE KEY-----
xxxxx
-----END RSA PRIVATE KEY-----
server:
http: 9503
websocket: 9504
tcp: 9505
# 日志配置
log:
# 日志文件路径 *请使用绝对路径*
path: "/path/to/.../runtime"
# Redis 相关配置
redis:
host: 43.138.153.157:6379
auth: xxxxx
database: 0
# Mysql 数据库配置
mysql:
host: 43.138.153.157
port: 3306
charset: utf8mb4
username: root
password: 111111
database: go_chat
collation: utf8mb4_general_ci
# Jwt 配置
jwt:
secret: 836c3fea9bba4e04d51bd0fbcc5
expires_time: 3600
buffer_time: 3600
openai:
key: "xxxx"
proxy: "https://api.openai.com"
# 跨域配置
cors:
origin: "*"
headers: "Content-Type,Cache-Control,User-Agent,Keep-Alive,DNT,AccessToken,Authorization"
methods: "OPTIONS,GET,POST,PUT,DELETE"
credentials: false
max_age: 600
# 文件系统配置【oss,qiniu 暂不支持】
filesystem:
default: local
local:
# 文件保存的根目录
root: "/path/xx/lumenim/"
# 公开的 bucket
bucket_public: "public"
# 私有的 bucket
bucket_private: "private"
endpoint: "im-cdn.gzydong.com"
ssl: false
minio:
secret_id: "xxxxxx"
secret_key: "xxxxx"
# 公开的 bucket
bucket_public: "im-static"
# 私有的 bucket
bucket_private: "im-private"
endpoint: "im-cdn.gzydong.com:9000"
ssl: false
# 邮件配置
email:
host: smtp.163.com
port: 465
username: xxxxx
password: xxxxx
fromname: "Lumen IM 在线聊天"
以上是配置文件内容
8.这时候要安装依赖包
go mod tidy
#但是要先安装go，以下是步骤
wget https://golang.google.cn/dl/go1.21.0.linux-amd64.tar.gz
tar -xvf go1.21.0.linux-amd64.tar.gz
vim /etc/profile
mkdir /home/gopath
source /etc/profile
go version
出来版本即可，要1.21.0
这时候执行go mod tidy，会有一段时间，后面就可以了
#其中有可能下载会遇到go 下载github包提示： dial tcp 172.217.160.81:443: i/o timeout ，这时候执行下面，然后重新安装依赖就可以
go env -w GOPROXY=https://goproxy.cn
##然后再安装依赖包
go mod tidy
9.安装相关依赖命令行工具
make install
10.安装完成后，要初始化数据库
go run ./cmd/lumenim migrate
#这时候又会遇到问题，有以下的，各自执行就行
问题：运行electorn . 报错:error while loading shared libraries: libX11-xcb.so.1
yum install libX11-devel --nogpg
问题: error while loading shared libraries: libatk-bridge-2.0.so.0
yum install at-spi2-atk -y
问题：error while loading shared libraries: libgtk-3.so.0
yum install gtk3 -y
问题：error while loading shared libraries: libXss.so.1
yum install libXScrnSaver* -y
问题：error while loading shared libraries: libdrm.so.2
yum install libdrm*
问题：error while loading shared libraries: libgbm.so.1
yum install libgbm*
11.再次初始化数据库
go run ./cmd/lumenim migrate
##这时候可能会爆内存，我服务器比较小，4g，直接爆了，虚拟内存加了8g，然后初始化成功了
下面是加交换分区的方法
创建要作为swap分区的文件:增加1GB大小的交换分区，则命令写法如下，其中的count等于想要的块的数量（bs*count=文件大小）。
dd if=/dev/zero of=/root/swapfile bs=1M count=1024
格式化为交换分区文件:
mkswap /root/swapfile #建立swap的文件系统
启用交换分区文件:
swapon /root/swapfile #启用swap文件
使系统开机时自启用，在文件/etc/fstab中添加一行：
/root/swapfile swap swap defaults 0 0
12.这时候完成后，启动后端即可
go run ./cmd/lumenim http # 本地启动 http 服务
go run ./cmd/lumenim commet # 本地启动 websocket 服务
