本文主要给大家介绍redis环境下mysql是如何实现lnmp架构缓存的，文章内容都是笔者用心摘选和编辑的，具有一定的针对性，对大家的参考意义还是比较大的，下面跟笔者一起了解下redis环境下mysql是如何实现lnmp架构缓存的吧。

配置环境：centos 7.2

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

123456789101112131415

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

12345678910111213

[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

123456789101112131415161718

[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：

123456789

[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 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

1234567891011121314151617181920212223242526272829303132333435363738394041

[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

1234567891011121314151617181920212223242526272829303132

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

1234567891011121314

[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

123456789101112

[root@server3 ~]# /etc/init.d/mysqld start[root@server3 ~]# mysql < test.sql[root@server3 ~]# mysql < test.sql[root@server3 ~]# cat test.sqluse 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

123456789101112131415161718

[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

123	[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

123456789101112131415161718

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

1234567

[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)
