redis服务器环境下mysql实现lnmp架构缓存

Redis  /  管理员 发布于 7年前   158

配置环境：redhat6.5

server1：redis（172.25.254.1）

server2：php（172.25.254.2）

server3：mysql（172.25.254.3）

配置步骤：

server2：

1、server2安装php的redis相应模块

2、nginx安装

[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: NOKEYPreparing...        ########################################### [100%]  1:nginx         ########################################### [100%]---------------------------------------------------------------------- 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 nginxuid=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 nginxuid=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 startStarting php-fpm:         [ OK ][root@server2 php-fpm.d]# netstat -antlp | grep phptcp    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]# lsdefault.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 -tnginx: the configuration file /etc/nginx/nginx.conf syntax is oknginx: configuration file /etc/nginx/nginx.conf test is successful[root@server2 conf.d]# nginx [root@server2 conf.d]# netstat -anplt |grep nginxtcp    0   0 0.0.0.0:80         0.0.0.0:*          LISTEN   1141/nginx

php测试：

[root@server2 conf.d]# cd /usr/share/nginx/html/[root@server2 html]# vim index.php[root@server2 html]# cat index.php <!--phpphpinfo()-->[root@server2 html]# /etc/init.d/php-fpm reloadReloading php-fpm: [14-Jul-2018 01:09:13] NOTICE: configuration file /etc/php-fpm.conf test is successful      [ OK ]

物理机访问：

4、php配置redis+mysql

[root@server2 ~]# cd /usr/share/nginx/html/[root@server2 html]# vim test.php   <!--php      $redis = new Redis();      $redis--->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); //如果没有找到$key,就将该查询sql的结果缓存到redis while ($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模块

[root@server2 ~]# unzip phpredis-master.zip [root@server2 ~]# cd phpredis-master[root@server2 phpredis-master]# phpize Configuring for:PHP Api Version:     20090626Zend Module Api No:   20090626Zend Extension Api No:  220090626[root@server2 phpredis-master]# lsacinclude.m4  config.sub   library.c     README.markdownaclocal.m4   configure    library.h     redis.cautom4te.cache configure.in  ltmain.sh     redis_session.cbuild      CREDITS     Makefile.global  redis_session.hcommon.h    debian     missing      run-tests.phpconfig.guess  debian.control mkdeb-apache2.sh serialize.listconfig.h.in   igbinary    mkinstalldirs   testsconfig.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]# lscurl.ini   json.ini   mysql.ini   pdo_sqlite.ini zip.inifileinfo.ini mbstring.ini pdo.ini    phar.inigd.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 reloadReloading 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 redisredisserver3:mysql配置

1、安装mysql-server

[root@server3 ~]# rpm -qa | grep mysqlmysql-community-common-5.7.17-1.el6.x86_64mysql-community-client-5.7.17-1.el6.x86_64mysql-community-libs-compat-5.7.17-1.el6.x86_64mha4mysql-node-0.56-0.el6.noarchmysql-community-libs-5.7.17-1.el6.x86_64mysql-community-server-5.7.17-1.el6.x86_64[root@server3 ~]# rpm -e `rpm -qa|grep mysql` --nodeps  ##不考虑依赖性删除mysqlwarning: /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 ##安装

2、开启mysql，并导入测试数据库

[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、数据库授权

[root@server3 ~]# mysqlmysql> 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)

测试：访问172.25.254.2/test.php

1、php默认从redis 索取数据，第一次redis无缓存，则php从mysql'索取数据

第一次无缓存

第二次索取数据后：

redis节点也可查看

[root@server1 redis-4.0.1]# redis-cli127.0.0.1:6379> get 2"test2"

2、将数据库server3节点内容更新并删除节点，则php从数据库索取数据节点更新内容

mysql> update test.test set name='westos' where id=1;Query OK, 1 row affected (0.05 sec)Rows matched: 1 Changed: 1 Warnings: 0mysql> 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主机删除节点内容

[root@server1 redis-4.0.1]# redis-cli127.0.0.1:6379> get 2"test2"127.0.0.1:6379> del 1(integer) 1127.0.0.1:6379> get 1(nil)

刷新页面，再次访问

以上redis 作为 mysql 的缓存服务器,但是如果更新了 mysql，redis中仍然会有对应的 KEY,数据就不会更新,此时就会出现 mysql 和 redis 数据不一致的情况。
