mysql+redis

mysql_with_redis_with_php_with_nginx大結合：

本版本mysql使用系統自帶的版本

redis，php，nginx等軟件及依賴性見官網及pkgs.org

server1.example.com :172.25.33.1 mysql

server2.example.com : 172.25.33.2 nginx +php

server3.example.com :172.25.33.3 redis

server1上安裝mysql-server

server2上安裝nginx和php及其擴展。

nginx所在的服務器需要和mysql，redis等溝通，相當於橋樑的作用，所以需要和他們相關的插件：
php-mysql

php-redis

[root@server2 redis]# ll phpredis-master.zip

-rwxr-xr-x 1 root root 83734 Oct 21 00:18 phpredis-master.zip

[root@server2 redis]# unzip phpredis-master.zip

-bash: unzip: command not found

安裝unzip解壓：

[root@server2 phpredis-master]# ls

common.h debian.control mkdeb-apache2.sh redis_session.c

config.m4 igbinary php_redis.h redis_session.h

CREDITS library.c README.markdown serialize.list

debian library.h redis.c tests

發現其中並沒有可執行文件，需要php的開發包php-devel

[root@server2 redis]# yum install -y php-devel-5.3.3-38.el6.x86_64.rpm

然後在當前目錄下執行phpize

phpize 的作用是偵測當前的php環境，並根據環境生成一個configure。

[root@server2 phpredis-master]# phpize

Configuring for:

PHP Api Version: 20090626

Zend Module Api No: 20090626

Zend Extension Api No: 220090626

[root@server2 phpredis-master]# ls

acinclude.m4 config.sub library.c README.markdown

aclocal.m4 configure library.h redis.c

autom4te.cache configure.in ltmain.sh redis_session.c

build CREDITS Makefile.global redis_session.h

common.h debian missing run-tests.php

config.guess debian.control mkdeb-apache2.sh serialize.list

config.h.in igbinary mkinstalldirs tests

config.m4 install-sh php_redis.h

編譯安裝：

編譯完成後並不會生成redis.ini文件，需要自己手動生成，php.ini 在php-common的目錄下邊：[root@server2 modules]# rpm -ql php-common

/etc/php.d

/etc/php.d/curl.ini

/etc/php.d/fileinfo.ini

/etc/php.d/json.ini

/etc/php.d/phar.ini

/etc/php.d/zip.ini

/etc/php.ini

[root@server2 php.d]# cp mysql.ini redis.ini

[root@server2 php.d]# vim redis.ini

[root@server2 php.d]# pwd

/etc/php.d

[root@server2 php.d]# cat redis.ini

; Enable mysql extension module

extension=redis.so

或者直接將redis.ini寫入php.ini中。

重起php-fpm，發現redis插件已經插入

[root@server2 php.d]# php -m |grep redis

redis

[root@server2 redis]# rpm -qa |grep php

php-cli-5.3.3-38.el6.x86_64

php-fpm-5.3.3-38.el6.x86_64

php-mysql-5.3.3-38.el6.x86_64

php-common-5.3.3-38.el6.x86_64

php-5.3.3-38.el6.x86_64

php-pdo-5.3.3-38.el6.x86_64

修改nginx的配配置文件：

[root@server2 redis]# !vi

vim /etc/nginx/conf.d/default.conf

8 location / {

9 root /usr/share/nginx/html;

10 index index.php index.html index.htm;

11 }

28 #pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

30 location ~ \.php$ {

31 root html;

32 fastcgi_pass 127.0.0.1:9000;

33 fastcgi_index index.php;

34 fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$fastcgi_script_name;

35 include fastcgi_params;

36 }

在/usr/share/nginx/html下編寫php的測試頁：
[root@server2 html]# ls

50x.html index.html index.php

[root@server2 html]# cat index.php

<?php

phpinfo()

啓動php-fpm服務。

[root@server2 html]# service php-fpm start

Starting php-fpm: [ OK ]

重起nginx服務

[root@server2 html]# service nginx restart

Stopping nginx: [ OK ]

Starting nginx: [ OK ]

然後即可通過網頁訪問php的測試頁：

***注意：在nginx的配置文件中定義的首頁是有順序的。

在server3.example.com 上安裝redis

解壓，直接make&& make install

有寫情況下可能需要安裝環境：(根據提示走)

jemalloc-3.6.0-1.el6.x86_64.rpm

jemalloc-devel-3.6.0-1.el6.x86_64.rpm

然後進入當前目錄的utils

安裝redis

[root@server3 utils]# ./install_server.sh

Welcome to the redis service installer

This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379]

Selecting default: 6379

然後一路回車

修改redis-server的配置文件：

[root@server3 utils]# vim /etc/redis/6379.conf

~~~~~~~~~~

62 bind 0.0.0.0

重起

[root@server3 utils]# /etc/init.d/redis_6379 restart

Stopping ...

Redis stopped

Starting Redis server...

[root@server3 utils]# netstat -antlp |grep redis

tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 4534/redis-server 0

redis監聽在所有端口，

測試：

數據庫和php的連接需要程序的支持：

[root@server2 redis]# cat test.php

<?php

$redis = new Redis();

$redis->connect('172.25.33.3',6379) or die ("could net connect redis server");

# $query = "select * from test limit 9";

$query = "select * from test";

for ($key = 1; $key < 10; $key++)

{

if (!$redis->get($key))

{

$connect = mysql_connect('172.25.33.1','redis','westos');

mysql_select_db(test);

$result = mysql_query($query);

//如果沒有找到$key,就將該查詢sql的結果緩存到redis

while ($row = mysql_fetch_assoc($result))

{

$redis->set($row['id'],$row['name']);

}

$myserver = 'mysql';

break;

}

else

{

$myserver = "redis";

$data[$key] = $redis->get($key);

}

echo $myserver;

echo " ";

for ($key = 1; $key < 10; $key++)

{

echo "number is $key";

echo " ";

echo "name is $data[$key]";

echo " ";

}

[root@server2 redis]#

將這個頁面作爲php的首頁。

[root@server2 redis]# cp test.php /usr/share/nginx/html/index.php

cp: overwrite `/usr/share/nginx/html/index.php'? y

在server1.example.com中插入數據

mysql> select * from test.test

-> ;

+----+-------+

| id | name |

+----+-------+

| 1 | test1 |

| 2 | test2 |

| 3 | test3 |

| 4 | test4 |

| 5 | test5 |

| 6 | test6 |

| 7 | test7 |

| 8 | test8 |

| 9 | test9 |

+----+-------+

爲index.php中的用戶授權

mysql> grant update on test.* to redis@'172.25.33.2' identified by 'westos' ;

在瀏覽器上測試：

即可得到數據庫響應的數據

此時有一個很大的缺陷：內容的一致性，redis在得到結果後，如果查找內容在其內存中存在，那麼，他就不會返回數據庫取數據，會造成數據的不一致性，所以需要添加一個觸發器：

配置gearman 實現數據同步

gearman 是一個支持分佈式的任務分發框架

gearman job server 作爲gearman的核心程序，需要編譯安裝並以守護進程形式運行在後臺。

gearman client 任務的請求者

gearman worker 任務執行着

在nginx所在的服務器安裝gearman

[root@server2 redis]# yum install -y gearmand-1.1.8-2.el6.x86_64.rpm

libgearman-1.1.8-2.el6.x86_64.rpm

[root@server2 redis]# yum install -y libgearman-devel-1.1.8-2.el6.x86_64.rpm libevent-devel-1.4.13-4.el6.x86_64.rpm libevent-headers-1.4.13-4.el6.noarch.rpm libevent-doc-1.4.13-4.el6.noarch.rpm

安裝php的gearman的擴展

安裝開發包。系統自帶

[root@server2 redis]# yum install -y db*-devel

編譯安裝gearman job server

[root@server2 redis]# tar -xf gearman-1.1.2.tgz

[root@server2 redis]# cd gearman-1.1.2

[root@server2 gearman-1.1.2]# ls

ChangeLog CREDITS LICENSE php_gearman.h test_client.php test_worker.php

[root@server2 php.d]# cat gearman.ini

; Enable mysql extension module

extension=gearman.so

或

[root@server2 php.d]# grep ^extension /etc/php.ini

extension = gearman.so

重起Php-fpm

在server1.example.com添加udf用戶自定義函數

由於要對數據庫進行操作，所以要安裝數據庫開發包

[root@server1 lib_mysqludf_json-master]# unzip lib_mysqludf_json-master.zip

[root@server1 lib_mysqludf_json-master]# cd lib_mysqludf_json-master

[root@server1 lib_mysqludf_json-master]# yum install -y mysql-devel

[root@server1 lib_mysqludf_json-master]# gcc $(mysql_config --cflags) -shared -fPIC -o lib_mysqludf_json.so lib_mysqludf_json.c

登陸數據庫，使用mysql> show global variables like 'plugin_dir';

+---------------+-------------------------+

| Variable_name | Value |

+---------------+-------------------------+

| plugin_dir | /usr/lib64/mysql/plugin |

+---------------+-------------------------+

1 row in set (0.00 sec)

找到數據庫插件所在的位置

[root@server1 lib_mysqludf_json-master]# ls

lib_mysqludf_json.c lib_mysqludf_json.so README.md

lib_mysqludf_json.html lib_mysqludf_json.sql

[root@server1 lib_mysqludf_json-master]# cp lib_mysqludf_json.so /usr/lib64/mysql/plugin/

將用戶自定義函數考入插件庫

安裝gearman-mysql用戶自定義函數：

[root@server1 redis]# yum install -y libgearman-1.1.8-2.el6.x86_64.rpm libgearman-devel-1.1.8-2.el6.x86_64.rpm libevent-devel-1.4.13-4.el6.x86_64.rpm libevent-doc-1.4.13-4.el6.noarch.rpm libevent-headers-1.4.13-4.el6.noarch.rpm

解壓gearman-mysql-udf-0.6

編譯安裝

[root@server1 gearman-mysql-udf-0.6]# ./configure --with-mysql=/usr/bin/mysql_config --libdir=/usr/lib64/mysql/plugin/

make && make install

註冊用戶自定義函數：

CREATE FUNCTION json_object RETURNS STRING SONAME 'lib_mysqludf_json.so';

編寫觸發器：

[root@server1 redis]# cat test.sql

use test;

#CREATE TABLE `test` (`id` int(7) NOT NULL AUTO_INCREMENT, `name` char(8) DEFAULT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;

#INSERT INTO `test` VALUES (1,'test1'),(2,'test2'),(3,'test3'),(4,'test4'),(5,'test5'),(6,'test6'),(7,'test7'),(8,'test8'),(9,'test9');

DELIMITER $$

CREATE TRIGGER datatoredis AFTER UPDATE ON test FOR EACH ROW BEGIN

SET @RECV=gman_do_background('syncToRedis', json_object(NEW.id as `id`, NEW.name as `name`));

END$$

DELIMITER ;

查看觸發器：

mysql> SHOW TRIGGERS FROM test;

編寫gearman 的worker端

[root@server2 redis]# cat worker.php

<?php

$worker = new GearmanWorker();

$worker->addServer();

$worker->addFunction('syncToRedis', 'syncToRedis');

$redis = new Redis();

$redis->connect('172.25.33.3', 6379);

while($worker->work());

function syncToRedis($job)

{

global $redis;

$workString = $job->workload();

$work = json_decode($workString);

if(!isset($work->id)){

return false;

}

$redis->set($work->id, $work->name);

}

直接後臺運行worker

[root@server2 redis]# nohup php worker.php &>/dev/null &
