1. redis介绍
- Redis和Memcached类似，也属于k-v数据存储
- Redis官网 redis.io, 当前最新稳定版4.0.1
支持更多value类型，除了和string外，还支持hash、lists（链表）、sets（集合）和sorted sets（有序集合） - redis使用了两种文件格式：全量数据(RDB)和增量请求(aof)。全量数据格式是把内存中的数据写入磁盘，便于下次读取文件进行加载。增量请求文件则是把内存中的数据序列化为操作请求，用于读取文件进行replay得到数据，这种类似于mysql binlog。
- redis的存储分为内存存储、磁盘存储和log文件三部分
2. redis安装
2.1 下载redis
[root@linux-02 src]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz

3. redis持久化
- Redis提供了两种持久化的方式，分别是RDB（Redis DataBase）和AOF（Append Only File）
- RDB，简而言之，就是在不同的时间点，将redis存储的数据生成快照并存储到磁盘等介质上。
- AOF，则是换了一个角度来实现持久化，那就是将redis执行过的所有写指令记录下来，在下次redis重新启动时，只要把这些写指令从前到后再重复执行一遍，就可以实现数据恢复了。
- 其实RDB和AOF两种方式也可以同时使用，在这种情况下，如果redis重启的话，则会优先采用AOF方式来进行数据恢复，这是因为AOF方式的数据恢复完整度更高。
- 如果你没有数据持久化的需求，也完全可以关闭RDB和AOF方式，这样的话，redis将变成一个纯内存数据库，就像memcache一样。
# save ""
save 900 1
save 300 10
save 60 10000
RDB持久化是如何实现把内存中的数据存储到磁盘上的呢，上面三条配置是redis.conf文件中的配置，表示的是900秒更改了一次，300秒更改了10次，60秒更改了10000次，就会导致把内存中的数据写入硬盘。如果说想关掉RDB持久化，可以把save这三行给注释，把save ""给打开即可。
# appendfsync always
appendfsync everysec
# appendfsync no
AOF持久化可以设置为上面三种模式，第一种是每时每刻都做备份，第二种是每秒，第三种是不做备份，可见第三种是最不安全的模式，第一种又会很占用系统磁盘的io，第二种是最合理也是最优的模式。
4.redis数据类型
4.1 string
- string为最简单的类型，与Memcached一样的类型，一个key对应一个value，其支持的操作与Memcached的操作类似，它的功能更丰富。设置可以存二进制的对象。
[root@linux-02 redis-5.0.5]# redis-cli
127.0.0.1:6379> set key1 123
OK
127.0.0.1:6379> get key1
"123"
127.0.0.1:6379> set ky2 abc ky3 bcd ky4 def
(error) ERR syntax error
127.0.0.1:6379> mset ky2 abc ky3 bcd ky4 def
OK
127.0.0.1:6379> MGET ky2 ky3 ky4
1) "abc"
2) "bcd"
3) "def"
127.0.0.1:6379>
4.2 list
- list是一个链表结构，主要功能是push、pop、获取一个范围的所有值等等。操作中key理解为链表的名字。
- 使用 list 结构，我们可以轻松地实现最新消息排行等功能（比如新浪微博的 TimeLine ）。list 的另一个应用就是消息队列，可以利用 list 的 push操作，将任务存在 list 中，然后工作线程再用pop操作将任务取出进行执行。

4.3 set集合
- set是集合，和我们数学中的集合概念相似，对集合的操作有添加删除元素，有对多个集合求交并差等操作。操作中key理解为集合的名字。比如在微博应用中，可以将一个用户所有的关注人存在一个集合中，将其所有粉丝存在一个集合。因为 Redis 非常人性化的为集合提供了求交集、并集、差集等操作，那么就可以非常方便的实现如共同关注、共同喜好、二度好友等功能，对上面的所有集合操作，你还可以使用不同的命令选择将结果返回给客户端还是存集到一个新的集合中。
127.0.0.1:6379> SADD set1 a //设置set1的值
(integer) 1
127.0.0.1:6379> SADD set1 b
(integer) 1
127.0.0.1:6379> SADD set1 c

4.4 有序集合sort set
- sorted set是有序集合，它比set多了一个权重参数score，使得集合中的元素能够按 score 进行有序排列，比如一个存储全班同学成绩的 Sorted Sets，其集合 value 可以是同学的学号，而 score 就可以是其考试得分，这样在数据插入集合的时候，就已经进行了天然的排序。
127.0.0.1:6379> ZADD set3 12 abc
(integer) 1
127.0.0.1:6379> ZADD set3 2 hddh
(integer) 1
127.0.0.1:6379> ZADD set3 24 klis
(integer) 1
127.0.0.1:6379> zadd set3 18 linux
(integer) 1
127.0.0.1:6379> ZRANGE set3 0 -1 //正序排列
1) "hddh"
2) "abc"
3) "linux"
4) "klis"
127.0.0.1:6379> ZREVRANGE set3 0 -1 //倒序排列
1) "klis"
2) "linux"
3) "abc"
4) "hddh"
4.5 hash
- 在 Memcached 中，我们经常将一些结构化的信息打包成 hashmap，在客户端序列化后存储为一个字符串的值（一般是 JSON 格式），比如用户的昵称、年龄、性别、积分等。
127.0.0.1:6379> HSET hash1 name xihaji
(integer) 1
127.0.0.1:6379> HSET hash1 age 18
(integer) 1
127.0.0.1:6379> HSET hash1 job it
(integer) 1
127.0.0.1:6379> HSET hash1 top gao
(integer) 1
127.0.0.1:6379> HGETALL hash1 //查看数值
1) "name"
2) "xihaji"
3) "age"
4) "18"
5) "job"

8) "gao"

127.0.0.1:6379>config set dir //修改配置信息
数据恢复： 首先定义或者确定dir目录和dbfilename，然后把备份的rdb文件放到dir目录下面，重启redis服务即可恢复数据
7. redis安全设置
- 设置监听ip
- bind 127.0.0.1 2.2.2.2//可以是多个ip，用空格分隔
- 设置监听端口
- port 16000
- 设置密码
- requirepass aming>com
- redis-cli -a ‘aming>com’
- 将config命令改名
- rename-command CONFIG aming
- 禁掉config命令
- rename-command CONFIG “”
8. redis慢查询日志
- 编辑配置文件/etc/redis.conf
- 针对慢查询日志，可以设置两个参数，一个是执行时长，单位是微秒，另一个是慢查询日志的长度。当一个新的命令被写入日志时，最老的一条会从命令日志队列中被移除。
- slowlog-log-slower-than 1000 //单位ms，表示慢于1000ms则记录日志
- slowlog-max-len 128 //定义日志长度，表示最多存128条
- slowlog get //列出所有的慢查询日志
- slowlog get 2 //只列出2条
- slowlog len //查看慢查询日志条数
9. PHP中使用redis
9.1 安装phpredis模块
[root@linux-02 ~]#cd /usr/local/src/
[root@linux-02 src]# wget https://coding.net/u/aminglinux/p/yuanke_centos7/git/raw/master/21NOSQL/phpredis.zip
[root@linux-02 src]# unzip phpredis.zip
[root@linux-02 src]# cd phpredis-develop/
[root@linux-02 phpredis-develop]# /usr/local/php-fpm/bin/phpize
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
[root@linux-02 phpredis-develop]# ./configure --with-php-config=/usr/local/php-fpm/bin/php-config
安装省略
[root@linux-02 phpredis-develop]# make
安装省略
[root@linux-02 phpredis-develop]# make install
Installing shared extensions: /usr/local/php-fpm/lib/php/extensions/no-debug-non-zts-20131226/
[root@linux-02 phpredis-develop]# ls /usr/local/php-fpm/lib/php/extensions/no-debug-non-zts-20131226/
memcache.so opcache.a opcache.so redis.so
[root@linux-02 phpredis-develop]# vim /usr/local/php-fpm/etc/php.ini
## 添加如下内容 ##
extension=redis.so
[root@linux-02 phpredis-develop]# /usr/local/php-fpm/bin/php -m |grep redis
redis
[root@linux-02 phpredis-develop]# /etc/init.d/php-fpm restart
9.2 redis 存储session
[root@linux-02 phpredis-develop]# vim /usr/local/php-fpm/etc/php-fpm.d/xihaji.conf
[test.com]
listen = /tmp/test.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
request_slowlog_timeout = 2
slowlog = /usr/local/php-fpm/var/log/xihaji_slow.log
php_admin_value[open_basedir]=/data/wwwroot/test.com/:/tmp/
php_value[session.save_handler] = redis
php_value[session.save_path] = " tcp://192.168.174.129:6379 "
如果想用php连接redis cluster，需要使用predis扩展
安装方法类似phpredis，predis扩展地址https://github.com/nrk/predis
10. redis主从
为了节省资源，我们可以在一台机器上启动两个redis服务
cp /etc/redis.conf /etc/redis2.conf
vim /etc/redis2.conf //需要修改port,dir,pidfile,logfile
port 6380
pidfile /var/run/redis_6380.pid
logfile "/var/log/redis2.log"
dir /data/redis2/
还要增加一行
slaveof 127.0.0.1 6379 是哪个redis的从，指定主是谁
如果主上设置了密码，还需要增加
masterauth tobe>com //设置主的密码
启动之前不要忘记创建新的dir目录
mkdir /data/redis2
redis-server /etc/redis2.conf
测试：在主上创建新的key，在从上查看
注意：redis主从和mysql主从不一样，redis主从不用事先同步数据，它会自动同步过去
11. redis集群
11.1 集群介绍
- 多个redis节点网络互联，数据共享
- 所有的节点都是一主一从（可以是多个从），其中从不提供服务，仅作为备用
- 不支持同时处理多个键（如mset/mget），因为redis需要把键均匀分布在各个节点上，并发量很高的情况下同时创建键值会降低性能并导致不可预测的行为。
- 支持在线增加、删除节点
- 客户端可以连任何一个主节点进行读写
11.1 集群搭建场景
- 场景设置：
- 两台机器，分别开启三个Redis服务(端口)
- A机器上三个端口7000,7002,7004，全部为主
- B机器上三个端口7001,7003,7005，全部为从
- 两台机器上都要编译安装redis,然后编辑并复制3个不同的redis.conf，分别设置不同的端口号、dir等参数，还需要增加cluster相关参数，然后分别启动6个redis服务
11.2 集群配置
ps：由于已经在129机器上已经redis编译过，可以直接把编译好的文件scp到128机器上，直接使用make install即可安装好redis
129机器上的配置文件如下：
[root@linux-02 etc]# cat /etc/redis_7000.conf

11.4 集群配置操作
cp /usr/local/src/redis-4.0.1/src/redis-trib.rb /usr/bin/
redis-trib.rb create --replicas 1 192.168.174.129:7000 192.168.174.129:7002 192.168.174.129:7004 192.168.174.128:7001 192.168.174.128:7003 192.168.174.128:7005
redis-cli -c -h 192.168.174.129 -p 7000//-c说明以集群的方式登录
任意一个节点都可以创建key，或者查看key（演示）
redis-trib.rb check 192.168.174.129:7000//检测集群状态
cluster nodes//列出节点
cluster info//查看集群信息
cluster meet ip port //添加节点
cluster forget node_id //移除某个节点
cluster replicate node_id//将当前节点设置为指定节点的从
cluster saveconfig//保存配置文件
