基于centos的redis与PHP

这是一个简要操作日记。。。

1、安装

安装PHPize。PHPize用于生成configure文件，为PHP扩展模块的编译生成配置文件。

yum install PHP-devel  -y

安装redis

yum install redis -y

从源码安装PHPredis

wget https://github.com/nicolasff/PHPredis/archive/master.zip
unzip master.zip
cd PHPredis-master/
PHPize
./configure
make && make install && make test

配置PHP添加扩展

find / -name PHP.ini
vi /etc/PHP.ini
G
extension="redis.so"
:wq
service httpd restart   # or reboot

测试PHPredis

[root@nfvbfqi9 ~]# PHP -a
Interactive shell
 
 
PHP > $redis= new Redis();
PHP > $redis->connect('127.0.0.1',6379);
PHP > $redis->set("pageview",10);
PHP > $k=$redis->get("pageview");
PHP > echo $k;
10

2、简单操作

redis

启动redis服务

加$令其后台执行，加（）表示在子shell中执行命令，纵然当前shell退出，此服务进程不会被kill。

(redis-server&)

加入开机自启动脚本

注意>表示写文件会清空原有内容，>>表示追加到文件末尾行。

echo "(redis-server&)" >>/etc/rc.local

启动redis命令行

redis-cli       #进入redis命令行模式

退出redis命令行

quit

注意不要用shutdown。shutdown命令会关闭当前redis服务，也即kill掉redis服务进程

dbsize                      #获取记录条数
set pageview 0              #设置k:v
get pageview                #获取k:v
del pageview                #删除k:v
save                        #保存
help @generic               #
