centos7.2 安装redis


wget http://download.redis.io/releases/redis-4.0.1.tar.gz    下载redis4.0.1 稳定版
tar zxf redis-4.0.1.tar.gz   解压redis
 cd redis-4.0.1                 进入redis
 make                              编译
 make install                   编译安装
 cp redis.conf   /etc/redis/端口号.conf
vim /etc/redis/端口号.conf
{
  daemonize no //改成后台运行 (改成yes)
  port //改成自己需要的端口
pidfile /var/run/redis_6379.pid (改成和你端口号一致)
}
 
/usr/local/bin/redis-server   /etc/redis/端口号.conf    启动redis

redis-cli -h 127.0.0.1 -p 7200   启动redis客户端 并指定端口和ip
能连接上就完事了

php 安装redis 
  wget https://github.com/phpredis/phpredis/archive/develop.zip 下载安装包
  unzip develop.zip 解压
  cd  phpredis-develop
  phpize
  ./configure --with-php-config=/usr/local/php/bin/php-config
  make 
  make install
  vim /usr/local/php/lib/php.ini (最底下加入extension="redis.so")
  php -m 有redis就成功了
  systemctl restart nginx.service
  systemctl restart php-fpm.service






测试redis类型
  string类型
set cdd lovenmm  存入字符串
get cdd (lovenmm)  取出字符串
    
set cdd2 5 存入数字
incr cdd2 自增1
decrby cdd2 2  自减2
 
  list 类型 (值可以重复)
lpush  list1  cdd 从左侧插入数据
lpush  list1  cdd3 从左侧插入数据3
lpop 从左侧弹出(cdd3) 先进后出
rpop 从右侧弹出 (cdd) 先进先出

rpush list2 cdd 从右侧插入数据

 set 类型(值不能重复)
sadd set1 12 插入记录
scard set1 查看里面有几个数据
sismember set1 12 判断数据是否存在 存在返回1 不存在返回0
srem set1 13 删除其中元素
 
hash 类型 (key值不能重复)
hset hash1 key1 12
hset hash1 key2 12
hget hash1 key1 (12) 获取key1里面的值
hlen hash1 获取集合里共有多少个元素
hmget hash1 key1 key2 一次查看多个值

 sort set类型(如果两个元素的值相同,按照value的字典序排序   value全局唯一)
zadd zset1 12.2 value1
zadd zset1 12.2 value2
zadd zset1 12.2 value3
zcard zset1 查看共有多少个数据
zrange zset1 0 2 查看0到2的排名
zrange zset1 0 2 withscores 查看0到2的排名并且列出分数
