更新時(shí)間：2018年07月18日 11:31:05 作者：weixin_41789003

這篇文章主要介紹了redis系統(tǒng)環(huán)境下mysql實(shí)現(xiàn)lnmp架構(gòu)緩存，本文給大家介紹的非常詳細(xì)，具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

配置環(huán)境：redhat6.5

server1：redis（172.25.254.1）

server2：php（172.25.254.2）

server3：mysql（172.25.254.3）

配置步驟：

server2：

1、server2安裝php的redis相應(yīng)模塊

2、nginx安裝

[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測(cè)試：

[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 ]

物理機(jī)訪問(wèn)：

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);
             //如果沒(méi)有找到$key,就將該查詢sql的結(jié)果緩存到redis
             while ($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模塊

[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、安裝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  ##不考慮依賴性刪除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 ##安裝

2、開(kāi)啟mysql，并導(dǎo)入測(cè)試數(shù)據(jù)庫(kù)

[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、數(shù)據(jù)庫(kù)授權(quán)

[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)

測(cè)試：訪問(wèn)172.25.254.2/test.php

1、php默認(rèn)從redis 索取數(shù)據(jù)，第一次redis無(wú)緩存，則php從mysql'索取數(shù)據(jù)

第一次無(wú)緩存

第二次索取數(shù)據(jù)后：

redis節(jié)點(diǎn)也可查看

[root@server1 redis-4.0.1]# redis-cli
127.0.0.1:6379> get 2
"test2"

2、將數(shù)據(jù)庫(kù)server3節(jié)點(diǎn)內(nèi)容更新并刪除節(jié)點(diǎn)，則php從數(shù)據(jù)庫(kù)索取數(shù)據(jù)節(jié)點(diǎn)更新內(nèi)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主機(jī)刪除節(jié)點(diǎn)內(nèi)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)

刷新頁(yè)面，再次訪問(wèn)

以上redis 作為 mysql 的緩存服務(wù)器,但是如果更新了 mysql，redis中仍然會(huì)有對(duì)應(yīng)的 KEY,數(shù)據(jù)就不會(huì)更新,此時(shí)就會(huì)出現(xiàn) mysql 和 redis 數(shù)據(jù)不一致的情況。

總結(jié)

以上所述是小編給大家介紹的redis服務(wù)器環(huán)境下mysql實(shí)現(xiàn)lnmp架構(gòu)緩存，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)腳本之家網(wǎng)站的支持！
