我有一个 Nest.js 应用程序，它在 docker 容器中运行并连接到 Oracle 数据库。
Dockerfile 是：
FROM node:20-alpine
RUN apk add --no-cache libaio unzip
COPY instantclient-basiclite-linux.zip /tmp/
RUN unzip /tmp/instantclient-basiclite-linux.zip -d /usr/lib/oracle && \
rm /tmp/instantclient-basiclite-linux.zip && \
ln -s /usr/lib/oracle/instantclient_21_8/libclntsh.so.21.1 /usr/lib/libclntsh.so
WORKDIR /usr/src/api
COPY . .
RUN yarn install
RUN yarn build
EXPOSE 3000
CMD ["yarn", "run", "start:prod"]
数据库配置类为：
import { Injectable, OnModuleDestroy } from '@nestjs/common';
import * as oracledb from 'oracledb';
import { Env } from 'src/env';
@Injectable()
export class DatabaseService implements OnModuleDestroy {
private connection: oracledb.Connection;
constructor() {
this.initializeOracleClient();
}
private getClientOptions() {
if (process.platform === 'win32') {
return { libDir: 'C:\\oracle\\instantclient_19_22' };
} else if (process.platform === 'darwin' && process.arch === 'x64') {
return { libDir: `${process.env.HOME}/Downloads/instantclient_19_8` };
} else if (process.platform === 'linux') {
return { libDir: '/usr/lib/oracle/instantclient_21_8' };
}
return undefined;
}
private initializeOracleClient() {
const clientOpts = this.getClientOptions();
if (clientOpts) oracledb.initOracleClient(clientOpts);
}
private async openConnection() {
try {
this.connection = await oracledb.getConnection({
user: Env.OWNER,
password: Env.PWD,
connectString: Env.CONNECT_STRING,
});
} catch (error) {
throw new Error('Falha na conexão com o banco de dados Oracle');
}
}
async executeQuery(query: string, params: any[] = []): Promise<any> {
if (!this.connection) await this.openConnection();
try {
const result = await this.connection.execute(query, params, {
outFormat: oracledb.OUT_FORMAT_OBJECT,
autoCommit: true,
});
return result.rows;
} catch (error: any) {
throw new Error(`Erro ao executar a consulta: ${error.message}`);
}
}
async onModuleDestroy() {
if (this.connection) {
try {
await this.connection.close();
} catch (error: any) {
throw new Error(`Erro ao fechar a conexão: ${error.message}`);
}
}
}
}
在项目的根目录中存在文件

如何解决这个问题？
错误信息是：
加载共享库 /usr/lib/oracle/instantclient_21_8/libclntsh.so 时出错：没有这样的文件或目录
您的跑步正在做：
ln -s /usr/lib/oracle/instantclient_21_8/libclntsh.so.21.1 /usr/lib/libclntsh.so
您应该将其链接到同一目录中：
ln -s /usr/lib/oracle/instantclient_21_8/libclntsh.so.21.1 /usr/lib/oracle/instantclient_21_8/libclntsh.so
