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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [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：
?
1 2 3 4 5 6 7 8 9 | [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 ] |
物理机访问：
4、php配置redis+mysql
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [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
?
1 2 3 | [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
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | 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
?
1 2 3 4 5 6 7 | [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) |
