# Redis 持久化
## RDB 持久化
RDB(Redis DataBase)持久化是将某一时刻的所有数据生成快照保存到硬盘的过程。
RDB 的优点:
* 对性能的影响较小,fork 出子进程来进行持久化。
* 文件紧凑,适合用于备份。
* RDB 文件是一个完整的数据集,可以被多个 Redis 实例加载。
RDB 的缺点:
* 数据安全性低,数据只在指定时间间隔内会被写入到磁盘一次,不能做到实时持久化。
* 如果数据量很大,fork 子进程可能会导致服务器停止服务几毫秒。
### 如何使用 RDB 持久化
RDB 持久化是由 `save` 和 `bgsave` 命令完成的。
`save` 命令会阻塞 Redis 进程,直到 RDB 文件创建完毕为止。因此不推荐使用该命令。
`bgsave` 命令会在后台异步执行 RDB 持久化,先调用 `fork` 创建子进程,然后由子进程负责创建新 RDB 文件,而父进程继续处理客户端请求。
### 如何配置 RDB 持久化
Redis 默认配置文件中包含两个相关的配置:
save ""
save ""
第一个配置项表示在指定时间间隔内有相应次数的写操作发生时,触发 RDB 持久化。因此可以根据实际情况配置成:
save "900" "1" # 在900秒内有至少1次写操作发生时执行 RDB 持久化
save "300" "10" # 在300秒内有至少10次写操作发生时执行 RDB 持久化
save "60" "10000" # 在60秒内有至少10000次写操作发生时执行 RDB 持久化
### RDB 文件的格式
RDB 文件格式由多个阶段组成:
1、头部(5 bytes)
REDIS0000rn$rn
其中 `` 表示后续内容长度。
如下图所示:

通过上图可以看出,该文件共有17字节:5字节的头部 + 长度字符串(4字节) + LF(1字节) + 数据内容(7字节)。
其它阶段如下图所示:

### 如何载入 RDB 文件
如果启动 Redis 并且配置了 `appendonly yes` 配置项,则 Redis 在载入 RDB 文件后会检查 AOF 文件是否存在。如果存在,则载入 AOF 文件;否则直接使用已经载入的 RDB 文件作为数据库状态。
如果没有配置 `appendonly yes` 则直接载入 RDB 文件作为数据库状态。
## AOF 持久化
AOF(Append Only File)持久化记录服务器执行过的所有写命令,并在服务器启动时通过重新执行这些命令来还原数据集。
AOF 的优点:
* 数据安全性高,可以通过不同 fsync 策略来控制同步频率,在确保服务器高性能的同时也不至于丢失过多的数据。
* 可读性强,AOF 日志文件以易于人类阅读和理解的格式保存了被执行过的写命令,在服务器重启后逐条重新执行这些命令即可还原数据库状态。
* 支持 AOF 日志重写机制,使得 AOF 日志文件尺寸不致于过大。
AOF 的缺点:
* 相比于 RDB,AOF 开启后文件尺寸通常较大。
* 根据 fsync 策略来决定性能和数据安全性之间的权衡。
* 如果开启 AOF 自动重写功能,在重写期间如果发生宕机,有可能造成一定程度上的数据丢失。
### 如何使用 AOF 持久化
默认情况下 Redis 不开启 AOF 持久化。通过配置 `appendonly yes` 开启 AOF 持久化后,所有对数据库进行写操作的命令都会追加到 AOF 文件的末尾。当服务器重启时,会通过重新执行这些命令来还原数据库状态。
### 如何配置 AOF 持久化
默认情况下 Redis 不开启 AOF 持久化。通过以下配置项来控制 AOF 的行为:
appendonly no # 是否开启AOF持久化
appendfilename "appendonly.aof" # AOF文件名,默认是 appendonly.aof
appendfsync always # 写命令同步策略:always(每次写命令都同步)、everysec(每秒钟同步一次)、no(交由操作系统来决定何时进行同步)
no-appendfsync-on-rewrite no # 在BGREWRITEAOF期间是否禁用fsync,默认为no(禁用),即使在BGREWRITEAOF期间也会调用fsync。设置为yes则表示在BGREWRITEAOF期间不调用fsync。
auto-aof-rewrite-percentage 100 # 当AOF文件大小超过上次重写之后大小的指定百分比时触发BGREWRITEAOF,默认值为100
auto-aof-rewrite-min-size int # 当AOF文件大小超过指定大小时触发BGREWRITEAOF,默认值为64mb
aof-load-truncated yes # 允许载入损坏的AOF文件,默认为no
### 如何载入 AOF 文件
如果开启了 AOF 持久化,则 Redis 在载入 AOF 文件后会检查是否存在 RBD 文件。如果存在,则忽略该文件;否则载入已经载入的 AOF 文件作为数据库状态。
如果没有开启 AOF,则直接载入 RBD 文件作为数据库状态。
### 命令追加规则
Redis 支持三种格式的命令追加规则:
1、**ASCII 纯文本**:将命令原样追加到文件中。
例如: `set key value`
追加到 AOF 文件中:
SET key value
这种格式可读性强,但是占用空间较大,并且在重放日志时需要花费更多时间来解析文本和分隔参数。
如下图所示:

这种方式可以通过配置项 `appendfilename` 来设置使用该格式追加命令:
appendfilename "appendonly.aof"
需要注意的是:这种方式是最早支持的方式,在新版本中已经不再推荐使用了。

2、**二进制安全**:将参数值进行编码后再追加到文件中。参数值前面添加一个字节表示参数值类型:
* 数值型:0x00 (正数)或者0x01 (负数)
* 字符串型:0x02
* 算术值:0x03
* 特殊类型:0x04 (整数数组)或者0x05 (浮点数数组)
例如: `set key value`
追加到 AOF 文件中:
+setrn$3rnkeyrn$5rnvaluern
这种方式可以通过配置项 `appendfilename` 来设置使用该格式追加命令:
appendfilename "appendonly.aof"
如下图所示:

---
3、**协议缓存**:将参数值进行编码后再追加到文件中。参数值前面添加一个字节表示参数值类型:
* 数值型:0x00 (正数)或者0x01 (负数)
* 字符串型:0x02
* 算术值:0x03
* 特殊类型:0x04 (整数数组)或者0x05 (浮点数数组)
例如: `set key value`
追加到 AOF 文件中:
*$3rn$3rnsetrn$3rnkeyrn$5rnvaluern
这种方式可以通过配置项 `appendfilename` 来设置使用该格式追加命令:
appendfilename "appendonly.aof"
如下图所示:

### 如何重写 AOF 日志
当 AOF 日志文件过大时,可以使用 BGREWRITEAOF 命令对日志进行重写。该命令执行过程如下:
1、创建一个子进程来重写日志,并同时将新旧两个日志同时保留。
* 新子进程将目前数据库状态转换成一系列被压缩过的写命令,并覆盖旧日志文件。
* 老 Redis 进程继续处理客户端请求,并将产生的新写命令追加到新日志文件末尾。
* 当子进程完成对新日志文件生成工作之后,向父进程发送信号通知完成。
