# RedisDB
|
||
|
||
RedisDB支持**哨兵模式**、**集群模式**与单节点的**普通模式**，封装了操作redis的常用的方法
|
||
|
||
## 连接
|
||
|
||
> 若环境变量中配置了数据库连接方式或者setting中已配置，则可不传参
|
||
|
||
### 普通模式
|
||
|
||
```python
|
||
from feapder.db.redisdb import RedisDB
|
||
|
||
db = RedisDB(ip_ports="localhost:6379", db=0, user_pass=None)
|
||
```
|
||
|
||
使用地址连接
|
||
|
||
```python
|
||
from feapder.db.redisdb import RedisDB
|
||
|
||
db = RedisDB.from_url("redis://[[username]:[password]]@[host]:[port]/[db]")
|
||
```
|
||
|
||
### 哨兵模式
|
||
|
||
```python
|
||
from feapder.db.redisdb import RedisDB
|
||
|
||
db = RedisDB(ip_ports="172.25.21.4:26379,172.25.21.5:26379,172.25.21.6:26379", db=0, user_pass=None, service_name="my_master")
|
||
```
|
||
|
||
注意：多个地址用逗号分隔，需传递`service_name`
|
||
|
||
对应setting配置文件，配置方式为：
|
||
|
||
```python
|
||
REDISDB_IP_PORTS = "172.25.21.4:26379,172.25.21.5:26379,172.25.21.6:26379"
|
||
REDISDB_USER_PASS = ""
|
||
REDISDB_DB = 0
|
||
REDISDB_SERVICE_NAME = "my_master"
|
||
```
|
||
|
||
### 集群模式
|
||
|
||
```python
|
||
from feapder.db.redisdb import RedisDB
|
||
|
||
db = RedisDB(ip_ports="172.25.21.4:26379,172.25.21.5:26379,172.25.21.6:26379", db=0, user_pass=None)
|
||
```
|
||
|
||
注意：多个地址用逗号分隔，不用传递`service_name`
|
||
|
||
对应setting配置文件，配置方式为：
|
||
|
||
```python
|
||
REDISDB_IP_PORTS = "172.25.21.4:26379,172.25.21.5:26379,172.25.21.6:26379"
|
||
REDISDB_USER_PASS = ""
|
||
REDISDB_DB = 0
|
||
```
|
