Linux安装redis PHP安装Redis扩展 and基本命令

$ mkdir /usr/local/redis #redis安装目录
$ cd /usr/local/src #安装包下载目录
$ wget http://download.redis.io/releases/redis-3.0.5.tar.gz #下载redis的包
$ tar xzf redis-3.0.5.tar.gz #解压
$ ln -s redis-2.6.14 redis #建立一个链接
$ cd redis
$ make PREFIX=/usr/local/redis install #安装到指定目录中

redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server

cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

vim /etc/rc.d/init.d/redis

$EXEC $CONF &

mkdir /etc/redis
cp /usr/local/src/redis/redis.conf /etc/redis/6379.conf

chkconfig --add redis

service redis start 也许你会遇到这个错误

env: /etc/init.d/redis: 权限不够

chmod a+x /etc/init.d/redis

a+x 是给所有人加上可执行权限，包括所有者，所属组，和其他人
o+x 只是给其他人加上可执行权限

vi /etc/profilem

export PATH="$PATH:/usr/local/redis/bin"

. /etc/profile

$ redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

$ wget https://github.com/phpredis/phpredis/archive/3.1.4.tar.gz
$ tar xzf 3.1.4.tar.gz
$ cd phpredis-3.1.4 # 进入 phpredis 目录
$ /usr/local/php/bin/phpize # php安装后的路径
$ ./configure --with-php-config=/usr/local/php/bin/php-config
$ make && make install

安装完成之后，出现下面的安装路径

/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/

vim /usr/local/php/etc/php.ini #编辑配置文件，在最后一行添加以下内容
extension="redis.so"


<?php
//连接本地的 Redis 服务
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//查看服务是否运行
echo "Server is running: " . $redis->ping();
?>

Connection to server sucessfully
Server is running: PONG

redis 127.0.0.1:6379> SET runoobkey redis
OK

redis 127.0.0.1:6379> DEL runoobkey (integer) 1
runoobkey 是一个键。 如果键被删除成功，命令执行后输出 (integer) 1，否则将输出 (integer) 0

redis 127.0.0.1:6379> SET runoobkey redis
OK
redis 127.0.0.1:6379> GET runoobkey
"redis"

127.0.0.1:6379> HMSET runoobkey name "redis tutorial" description "redis basic commands for caching" likes 20 visitors 23000
OK
127.0.0.1:6379> HGETALL runoobkey
1) "name"
2) "redis tutorial"
3) "description"
4) "redis basic commands for caching"
5) "likes"
6) "20"
7) "visitors"
8) "23000"
设置了 redis 的一些描述信息(name, description, likes, visitors) 到哈希表的 runoobkey 中

redis 127.0.0.1:6379> LPUSH mylist hello
(integer) 1
redis 127.0.0.1:6379> LPUSH mylist world
(integer) 2
redis 127.0.0.1:6379> LRANGE mylist 0 101) "hello"
2) "world"Redis列表是简单的字符串列表，按照插入顺序排序。你可以添加一个元素到列表的头部（左边）或者尾部（右边）

redis 127.0.0.1:6379> SADD runoobkey redis
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mongodb
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mysql
(integer) 1
redis 127.0.0.1:6379> SADD runoobkey mysql
(integer) 0
redis 127.0.0.1:6379> SMEMBERS runoobkey1) "mysql"
2) "mongodb"
3) "redis"Redis 的 Set 是 String 类型的无序集合。集合成员是唯一的，这就意味着集合中不能出现重复的数据。Redis 中集合是通过哈希表实现的
通过 SADD 命令向名为 runoobkey 的集合插入的三个元素。
