NoSQL -- php应用redis、mongodb

 php - redis 

安装扩展模块

wget https://codeload.github.com/phpredis/phpredis/zip/develop
mv develop phpredis.zip
unzip phpredis.zip
cd phpredis-develop
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config  
make && make install
vim /usr/local/php/php.ini  // 增加一行extension = redis.so
/usr/local/php/bin/php -m |grep redis 检查是否成功

redis的session共享

php.ini中加入   //不建议
   session.save_handler = "redis"
   session.save_path = "tcp://127.0.0.1:6379"
或者apache虚拟主机加入   //用于LAMP架构中
   php_value session.save_handler " redis"

php_value session.save_path " tcp://127.0.0.1:6379" 
或者php-fpm.conf对应的pool中加入   //用于LNMP架构
   php_value[session.save_handler] = redis
   php_value[session.save_path] = " tcp://127.0.0.1:6379 "   //ip可换成远端redis服务器ip
redis的session测试

vim /usr/local/apache/htdocs/session.php

<?php 
session_start(); 
if (!isset($_SESSION[‘TEST‘])) { 
$_SESSION[‘TEST‘] = time(); 
} 
$_SESSION[‘TEST3‘] = time(); 
print $_SESSION[‘TEST‘]; 
print "<br><br>"; 
print $_SESSION[‘TEST3‘]; 
print "<br><br>"; 
print session_id(); 
?>

测试curl  localhost/session.php  或 web访问

输出1443710814<br><br>1443710814<br><br>9jm6nom9ogojedj3pth0iscv22

连接redis
/usr/local/redis/bin/redis-cli
127.0.0.1:6379> keys *   //可以把所有的key都列出来
"PHPREDIS_SESSION:9jm6nom9ogojedj3pth0iscv22"
127.0.0.1:6379> get PHPREDIS_SESSION:9jm6nom9ogojedj3pth0iscv22
"TEST|i:1443710814;TEST3|i:1443710814;"

error：如果 curl 不出东西加 -I 后报500而且日志中看不出东西

解决# display_errors = Off 改为 display_errors = On   //此时 curl 会输出错误之后记得改回去

 php - mongodb 

安装mongodb扩展

wget ‘https://codeload.github.com/mongodb/mongo-php-driver/zip/master‘ -O /usr/local/src/mong_php.zip
cd /usr/local/src/
unzip mong_php.zip
cd mongo-php-driver-master/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
vi /usr/local/php/etc/php.ini //增加 extension = mongo.so
/usr/local/php/bin/php –m
重启apache重新加载php

mongodb 测试扩展

vi /usr/local/apache2/htdocs/1.php //增加

<?php
// 连接到mongodb
$m = new MongoClient();
echo "Connection to database successfully";
// 选择一个数据库
$db = $m->mydb;
echo "Database mydb selected";
?>

测试curl  localhost/1.php
