吾爱主题阅读：103 2024-04-05 14:01:11 评论：0

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

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 <! --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

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)
