redis服务器环境下mysql实现lnmp架构缓存
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: NOKEY Preparing... ########################################### [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 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测试:
[root@server2 conf.d]# cd /usr/share/nginx/html/ [root@server2 html]# vim index.php [root@server2 html]# cat index.php <!--php phpinfo() --> [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: 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、安装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 ##不考虑依赖性删除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 ~]# 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)
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-cli 127.0.0.1:6379> 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: 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主机删除节点内容
[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。
