+#### 配置参数表
+
+| 配置项 | 说明 |
+| :-- | :-- |
+| `daemonize no` | Redis 默认不是以守护进程的方式运行，可以通过该配置项修改，使用 yes 启用守护进程（Windows 不支持守护线程的配置为 no ） |
+| `pidfile /var/run/redis.pid` | 当 Redis 以守护进程方式运行时，Redis 默认会把 pid 写入 /var/run/redis.pid 文件，可以通过 pidfile 指定 |
+| `port 6379` | 指定 Redis 监听端口，默认端口为 6379，作者在自己的一篇博文中解释了为什么选用 6379 作为默认端口，因为 6379 在手机按键上 MERZ 对应的号码，而 MERZ 取自意大利歌女 Alessia Merz 的名字 |
+| `bind 127.0.0.1` | 绑定的主机地址 |
+| `timeout 300` | 当客户端闲置多长时间后关闭连接，如果指定为 0，表示关闭该功能 |
+| `loglevel notice` | 指定日志记录级别，Redis 总共支持四个级别：debug、verbose、notice、warning，默认为 notice |
+| `logfile stdout` | 日志记录方式，默认为标准输出，如果配置 Redis 为守护进程方式运行，而这里又配置为日志记录方式为标准输出，则日志将会发送给 /dev/null |
+| `databases 16` | 设置数据库的数量，默认数据库为 0，可以使用 SELECT 命令在连接上指定数据库 id |
+| `save <seconds> <changes>` Redis 默认配置文件中提供了三个条件：**save 900 1**、**save 300 10**、**save 60 10000** 分别表示 900 秒（15 分钟）内有 1 个更改，300 秒（5 分钟）内有 10 个更改以及 60 秒内有 10000 个更改。 | 指定在多长时间内，有多少次更新操作，就将数据同步到数据文件，可以多个条件配合 |
+| `rdbcompression yes` | 指定存储至本地数据库时是否压缩数据，默认为 yes，Redis 采用 LZF 压缩，如果为了节省 CPU 时间，可以关闭该选项，但会导致数据库文件变的巨大 |
+| `dbfilename dump.rdb` | 指定本地数据库文件名，默认值为 dump.rdb |
+| `dir ./` | 指定本地数据库存放目录 |
+| `slaveof <masterip> <masterport>` | 设置当本机为 slav 服务时，设置 master 服务的 IP 地址及端口，在 Redis 启动时，它会自动从 master 进行数据同步 |
+| `masterauth <master-password>` | 当 master 服务设置了密码保护时，slav 服务连接 master 的密码 |
+| `requirepass foobared` | 设置 Redis 连接密码，如果配置了连接密码，客户端在连接 Redis 时需要通过 AUTH <password> 命令提供密码，默认关闭 |
+| `maxclients 128` | 设置同一时间最大客户端连接数，默认无限制，Redis 可以同时打开的客户端连接数为 Redis 进程可以打开的最大文件描述符数，如果设置 maxclients 0，表示不作限制。当客户端连接数到达限制时，Redis 会关闭新的连接并向客户端返回 max number of clients reached 错误信息 |
+| `maxmemory <bytes>` | 指定 Redis 最大内存限制，Redis 在启动时会把数据加载到内存中，达到最大内存后，Redis 会先尝试清除已到期或即将到期的 Key，当此方法处理 后，仍然到达最大内存设置，将无法再进行写入操作，但仍然可以进行读取操作。Redis 新的 vm 机制，会把 Key 存放内存，Value 会存放在 swap 区 |
+| `appendonly no` | 指定是否在每次更新操作后进行日志记录，Redis 在默认情况下是异步的把数据写入磁盘，如果不开启，可能会在断电时导致一段时间内的数据丢失。因为 redis 本身同步数据文件是按上面 save 条件来同步的，所以有的数据会在一段时间内只存在于内存中。默认为 no |
+| `appendfilename appendonly.aof` | 指定更新日志文件名，默认为 appendonly.aof |
+| `appendfsync everysec` | 指定更新日志条件，共有 3 个可选值：**no**：表示等操作系统进行数据缓存同步到磁盘（快）**always**：表示每次更新操作后手动调用 fsync() 将数据写到磁盘（慢，安全）**everysec**：表示每秒同步一次（折中，默认值） |
+| `vm-enabled no` | 指定是否启用虚拟内存机制，默认值为 no，简单的介绍一下，VM 机制将数据分页存放，由 Redis 将访问量较少的页即冷数据 swap 到磁盘上，访问多的页面由磁盘自动换出到内存中（在后面的文章我会仔细分析 Redis 的 VM 机制） |
+| `vm-swap-file /tmp/redis.swap` | 虚拟内存文件路径，默认值为 /tmp/redis.swap，不可多个 Redis 实例共享 |
+| `vm-max-memory 0` | 将所有大于 vm-max-memory 的数据存入虚拟内存，无论 vm-max-memory 设置多小，所有索引数据都是内存存储的(Redis 的索引数据 就是 keys)，也就是说，当 vm-max-memory 设置为 0 的时候，其实是所有 value 都存在于磁盘。默认值为 0 |
+| `vm-page-size 32` | Redis swap 文件分成了很多的 page，一个对象可以保存在多个 page 上面，但一个 page 上不能被多个对象共享，vm-page-size 是要根据存储的 数据大小来设定的，作者建议如果存储很多小对象，page 大小最好设置为 32 或者 64bytes；如果存储很大大对象，则可以使用更大的 page，如果不确定，就使用默认值 |
+| `vm-pages 134217728` | 设置 swap 文件中的 page 数量，由于页表（一种表示页面空闲或使用的 bitmap）是在放在内存中的，，在磁盘上每 8 个 pages 将消耗 1byte 的内存。 |
+| `vm-max-threads 4` | 设置访问 swap 文件的线程数,最好不要超过机器的核数,如果设置为 0,那么所有对 swap 文件的操作都是串行的，可能会造成比较长时间的延迟。默认值为 4 |
+| `glueoutputbuf yes` | 设置在向客户端应答时，是否把较小的包合并为一个包发送，默认为开启 |
+| `hash-max-zipmap-entries 64 hash-max-zipmap-value 512` | 指定在超过一定的数量或者最大的元素超过某一临界值时，采用一种特殊的哈希算法 |
+| `activerehashing yes` | 指定是否激活重置哈希，默认为开启（后面在介绍 Redis 的哈希算法时具体介绍） |
+| `include /path/to/local.conf` | 指定包含其它的配置文件，可以在同一主机上多个 Redis 实例之间使用同一份配置文件，而同时各个实例又拥有自己的特定配置文件 |
+

 Redis 3.0 后支持集群模式。
