# 微服务
## 环境搭建
### Docker镜像源设置
```bash
# 创建目录
sudo mkdir -p /etc/docker
# 写入配置文件
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": [
"https://docker-0.unsee.tech",
"https://docker-cf.registry.cyou",
"https://docker.1panel.live"
]
}
EOF
# 重启docker服务
sudo systemctl daemon-reload && sudo systemctl restart docker
```
使用docker-compose有的时候会因为版本不同，但是配置文件主要内容就是这些。需要注意版本问题
### 配置相关
#### MySQL配置问题
| **特性** | `**my.cnf**` | `**conf.d**` **目录** |
| ------------ | ---------------------------- | -------------------------- |
| **文件类型** | 单个文件 | 目录，包含多个 `.cnf` 文件 |
| **配置方式** | 集中式配置 | 分布式配置 |
| **优先级** | 高（覆盖 `conf.d` 中的配置） | 低（被 `my.cnf` 覆盖） |
| **适用场景** | 全局配置，核心配置 | 模块化配置，便于扩展和维护 |
#### MongoDB配置
```bash
sudo mkdir -p ~/docker/docker_data/mongo/conf
sudo mkdir -p ~/docker/docker_data/mongo/logs
sudo chmod 777 ~/docker/docker_data/mongo/logs
sudo chmod 777 ~/docker/docker_data/mongo/conf
cd ~/docker/docker_data/mongo/logs
sudo touch mongod.log
sudo chmod 777 mongod.log
cd ~/docker/docker_data/mongo/conf
sudo vim mongod.conf
cd ~
```
##### 配置文件
```bash
# 数据库文件存储位置
dbpath = /data/db
# log文件存储位置
logpath = /data/log/mongod.log
# 使用追加的方式写日志
logappend = true
# 是否以守护进程方式运行
# fork = true
# 全部ip可以访问
bind_ip = 0.0.0.0
# 端口号
port = 27017
# 是否启用认证
auth = true
# 设置oplog的大小(MB)
oplogSize=2048
```
##### 设置账户密码
```shell
#进入容器
docker exec -it mongodb /bin/bash
#进入mongodb shell
mongosh --port 27017
#切换到admin库
use admin
#创建账号/密码
db.createUser({ user: 'admin', pwd: '02120212', roles: [ { role: "root", db: "admin" } ] });
# db.createUser({ user: 'admin', pwd: '123456', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });
```
### docker-compose.yml
如果休要所有的微服务环境，可以直接复制下面的内容，看清楚目录是否和自己需要的一样。
| 功能 | 旧版 (docker-compose) | 新版 (docker compose) |
| -------------------- | ----------------------- | ----------------------- |
| **启动服务** | docker-compose up -d | docker compose up -d |
| **停止服务** | docker-compose down | docker compose down |
| **查看日志** | docker-compose logs -f | docker compose logs -f |
| **列出容器** | docker-compose ps | docker compose ps |
| **停止不删除容器** | docker-compose stop | docker compose stop |
| **启动已停止的容器** | docker-compose start | docker compose start |
| **重启服务** | docker-compose restart | docker compose restart |
| **构建镜像** | docker-compose build | docker compose build |
