## YML文件MYSQL密码加密存储手册
|
||
|
||
### 1、本地部署加密
|
||
|
||
**第一步：生成密文**
|
||
|
||
在本地仓库中找到jasypt-1.9.3.jar，默认在org/jasypt/jasypt/1.9.3中，使用`java -cp`生成密文。
|
||
|
||
```bash
|
||
java -cp jasypt-1.9.3.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input=mysql密码 password=加密的salt algorithm=PBEWithMD5AndDES
|
||
```
|
||
|
||
```bash
|
||
## 得到密文
|
||
DYbVDLg5D0WRcJSCUGWjiw==
|
||
```
|
||
|
||
**第二步：配置jasypt**
|
||
|
||
在YML文件中配置jasypt，例如
|
||
|
||
```yaml
|
||
jasypt:
|
||
encryptor:
|
||
algorithm: PBEWithMD5AndDES
|
||
iv-generator-classname: org.jasypt.iv.NoIvGenerator
|
||
```
|
||
|
||
**第三步：配置密文**
|
||
|
||
使用密文替换YML文件中的明文密码为ENC(密文），例如[application.yml](https://github.com/didi/KnowStreaming/blob/master/km-rest/src/main/resources/application.yml)中MYSQL密码。
|
||
|
||
```yaml
|
||
know-streaming:
|
||
username: root
|
||
password: ENC(DYbVDLg5D0WRcJSCUGWjiw==)
|
||
```
|
||
|
||
**第四步：配置加密的salt（选择其一）**
|
||
|
||
- 配置在YML文件中（不推荐）
|
||
|
||
```yaml
|
||
jasypt:
|
||
encryptor:
|
||
password: salt
|
||
```
|
||
|
||
- 配置程序启动时的命令行参数
|
||
|
||
```bash
|
||
java -jar xxx.jar --jasypt.encryptor.password=salt
|
||
```
|
||
|
||
- 配置程序启动时的环境变量
|
||
|
||
```bash
|
||
export JASYPT_PASSWORD=salt
|
||
java -jar xxx.jar --jasypt.encryptor.password=${JASYPT_PASSWORD}
|
||
```
|
||
|
||
## 2、容器部署加密
|
||
|
||
利用docker swarm 提供的 secret 机制加密存储密码，使用docker swarm来管理密码。
|
||
|
||
### 2.1、secret加密存储
|
||
|
||
**第一步：初始化docker swarm**
|
||
|
||
```bash
|
||
docker swarm init
|
||
```
|
||
|
||
**第二步：创建密钥**
|
||
|
||
```bash
|
||
echo "admin2022_" | docker secret create mysql_password -
|
||
|
||
# 输出密钥
|
||
f964wi4gg946hu78quxsh2ge9
|
||
```
|
||
|
||
**第三步：使用密钥**
|
||
|
||
```yaml
|
||
# mysql用户密码
|
||
SERVER_MYSQL_USER: root
|
||
SERVER_MYSQL_PASSWORD: mysql_password
|
||
|
||
knowstreaming-mysql:
|
||
# root 用户密码
|
||
MYSQL_ROOT_PASSWORD: mysql_password
|
||
secrets:
|
||
mysql_password:
|
||
external: true
|
||
```
|
||
|
||
### 2.2、使用密钥文件加密
|
||
|
||
**第一步：创建密钥**
|
||
|
||
```bash
|
||
echo "admin2022_" > password
|
||
```
|
||
|
||
**第二步：使用密钥**
|
||
|
||
```yaml
|
||
# mysql用户密码
|
||
SERVER_MYSQL_USER: root
|
||
SERVER_MYSQL_PASSWORD: mysql_password
|
||
secrets:
|
||
mysql_password:
|
||
file: ./password
|
||
```
