Redis的安装部署

Posted 2021-12-03 韦建国

安装php

yum install php php-devel -y

安装php扩展支持memcache

yum -y install php-pecl-memcache

yum -y install php56w-pecl-memcache //如php端是5.6，我们不是5.6，不用装

安装redis

----------------------------------------------------------------------------------------------------

安装redis和php支持模块

rpm -Uvh ​​https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm​​ //下载源

yum clean all

yum install -y redis php-redis //让php支持redis

添加php支持redis模块 在结尾处进行添加

vim /etc/php.ini

-------------------------------------------------

extension=redis.so

-------------------------------------------------

systemctl restart httpd //重启httpd ，php也会随之起来

vim /etc/redis.conf //开启进程，才能启动

---------------------------------------------------------

daemonize yes

---------------------------------------------------------

systemctl restart redis

ps -ef | grep redis

测试：

---------------------------------------------------------------

测试一下客户端是否好用

redis-cli set hx value //存值

redis-cli get hx //取值

添加测试页面

cd /var/www/html/

vim test.php

-----------------------------------------------

<?php

phpinfo();

?>

-----------------------------------------------

vim session.php //统计网页的访问次数

---------------------------------------------------------------------------------

<?php

session_start();

$count = isset($_SESSION[count]) ? $_SESSION[count] : 1;

echo $count;

$_SESSION[count] = ++$count;

?>

--------------------------------------------------------------------------------

vim redis.php

------------------------------------------------------------------------------------------

<?php

$redis = new Redis();

$redis->connect(127.0.0.1, 6379);

$redis->set(key, value);

echo $redis->get(key)."\\n";

$redis->setex(key, 3600, value); // sets key → value, with 1h TTL.

$redis->set(key1, val1);

$redis->set(key2, val2);

$redis->set(key3, val3);

$redis->set(key4, val4);

$redis->delete(key1, key2);

echo $redis->get(key3)."\\n" ;

$redis->delete(array(key3, key4));

?>

新测试页面：

通过key获取value

<?php

$redis = new Redis();

$redis->connect(127.0.0.1, 6379);

$redis->set(jkl, 123);

echo $redis->get(jkl)."\\n";

?>
