配置環境：redhat6.5

server1：redis(172.25.254.1)

server2：php(172.25.254.2)

server3：mysql(172.25.254.3)

配置步驟：

server2：

1、server2安裝php的redis相應模塊

2、nginx安裝

[root@server2 php-fpm.d]# rpm -ivh nginx-1.8.0-1.el6.ngx.x86_64.rpm

warning: nginx-1.8.0-1.el6.ngx.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY

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

Thanks for using nginx!

Please find the official documentation for nginx here:

* https://nginx.org/en/docs/

Commercial subscriptions for nginx are available on:

* https://nginx.com/products/

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

[root@server2 php-fpm.d]# id nginx

uid=498(nginx) gid=499(nginx) groups=499(nginx)

3、nginx和php配置

1、php配置

[root@server2 php-fpm.d]# cd /etc/php-fpm.d/

[root@server2 php-fpm.d]# id nginx

uid=498(nginx) gid=499(nginx) groups=499(nginx)

[root@server2 php-fpm.d]# vim www.conf

39 user = nginx

41 group = nginx

[root@server2 php-fpm.d]# vim /etc/php.ini

946 date.timezone = Asia/Shanghai

[root@server2 php-fpm.d]# /etc/init.d/php-fpm start

Starting php-fpm: [ OK ]

[root@server2 php-fpm.d]# netstat -antlp | grep php

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 1125/php-fpm

[root@server2 php-fpm.d]# vim /etc/php.ini

2、nginx配置

[root@server2 ~]# cd /etc/nginx/conf.d/

[root@server2 conf.d]# ls

default.conf example_ssl.conf

[root@server2 conf.d]# vim default.conf

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

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 }

[root@server2 conf.d]# nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@server2 conf.d]# nginx

[root@server2 conf.d]# netstat -anplt |grep nginx

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1141/nginx

php測試：

[root@server2 conf.d]# cd /usr/share/nginx/html/

[root@server2 html]# vim index.php

[root@server2 html]# cat index.php

[root@server2 html]# /etc/init.d/php-fpm reload

Reloading php-fpm: [14-Jul-2018 01:09:13] NOTICE: configuration file /etc/php-fpm.conf test is successful

[ OK ]

物理機訪問：

4、php配置redis+mysql

[root@server2 ~]# cd /usr/share/nginx/html/

[root@server2 html]# vim test.php

connect('172.25.254.1',6379) or die ("could net connect redi s server");

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

$query = "select * from test";

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

{

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

{

$connect = mysql_connect('172.25.254.3','redis','wes tos');

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 "

";

}

5、添加php支持的redis模塊

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

[root@server2 ~]# cd phpredis-master

[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

[root@server2 phpredis-master]# ./configure

[root@server2 phpredis-master]# make && make install

[root@server2 ~]# cd /etc/php.d/

[root@server2 php.d]# ls

curl.ini json.ini mysql.ini pdo_sqlite.ini zip.ini

fileinfo.ini mbstring.ini pdo.ini phar.ini

gd.ini mysqli.ini pdo_mysql.ini sqlite3.ini

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

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

2 extension=redis.so

[root@server2 php.d]# /etc/init.d/php-fpm reload

Reloading php-fpm: [14-Jul-2018 01:21:56] NOTICE: configuration file /etc/php-fpm.conf test is successful

[ OK ]

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

redis

server3:mysql配置

1、安裝mysql-server

[root@server3 ~]# rpm -qa | grep mysql

mysql-community-common-5.7.17-1.el6.x86_64

mysql-community-client-5.7.17-1.el6.x86_64

mysql-community-libs-compat-5.7.17-1.el6.x86_64

mha4mysql-node-0.56-0.el6.noarch

mysql-community-libs-5.7.17-1.el6.x86_64

mysql-community-server-5.7.17-1.el6.x86_64

[root@server3 ~]# rpm -e `rpm -qa|grep mysql` --nodeps ##不考慮依賴性刪除mysql

warning: /etc/my.cnf saved as /etc/my.cnf.rpmsave

[root@server3 ~]# rpm -qa | grep mysql

[root@server3 ~]# cd /var/lib/mysql/

[root@server3 mysql]# rm -fr *

[root@server3 mysql]# ls

[root@server3 mysql]# yum install -y mysql-server ##安裝

2、開啟mysql，并導入測試數據庫

[root@server3 ~]# /etc/init.d/mysqld start

[root@server3 ~]# mysql < test.sql

[root@server3 ~]# mysql < test.sql

[root@server3 ~]# 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 ;

3、數據庫授權

[root@server3 ~]# mysql

mysql> grant all on test.* to redis@'%' identified by 'westos';

Query OK, 0 rows affected (0.00 sec)

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 |

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

9 rows in set (0.00 sec)

測試：訪問172.25.254.2/test.php

1、php默認從redis 索取數據，第一次redis無緩存，則php從mysql'索取數據

第一次無緩存

第二次索取數據后：

redis節點也可查看

[root@server1 redis-4.0.1]# redis-cli

127.0.0.1:6379> get 2

"test2"

2、將數據庫server3節點內容更新并刪除節點，則php從數據庫索取數據節點更新內容

mysql> update test.test set name='westos' where id=1;

Query OK, 1 row affected (0.05 sec)

Rows matched: 1 Changed: 1 Warnings: 0

mysql> select * from test.test;

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

| id | name |

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

| 1 | westos |

| 2 | test2 |

| 3 | test3 |

| 4 | test4 |

| 5 | test5 |

| 6 | test6 |

| 7 | test7 |

| 8 | test8 |

| 9 | test9 |

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

9 rows in set (0.00 sec)

redis的master主機刪除節點內容

[root@server1 redis-4.0.1]# redis-cli

127.0.0.1:6379> get 2

"test2"

127.0.0.1:6379> del 1

(integer) 1

127.0.0.1:6379> get 1

(nil)

刷新頁面，再次訪問

以上redis 作為 mysql 的緩存服務器,但是如果更新了 mysql，redis中仍然會有對應的 KEY,數據就不會更新,此時就會出現 mysql 和 redis 數據不一致的情況。

總結
