需要具备一体化LNMP一台，在此基础上进行操作
phpredis-master.zip 点此下载 提取码：3fdh
1）LNMP上打redis模块
171 unzip phpredis-master.zip 172 cd phpredis-master 173 ls 174 phpize 175 ln -s /usr/local/php/bin/* /usr/local/bin/ 176 ln -s /usr/local/php/sbin/* /usr/local/sbin/ 177 phpize 178 ./configure --with-php-config=/usr/local/php/bin/php-config 179 make 180 make install 181 ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/ 182 vim /usr/local/php/php.ini 末行添加内容，如下： extension=redis.so 183 /etc/init.d/php-fpm restart 184 firefox 127.0.0.1打完模块后，可以在php页面看到redis模块，如下图
2）本机安装redis并修改配置文件
安装过程 202 tar -zxf redis-4.0.2.tar.gz 203 cd redis-4.0.2 204 make 205 make install 206 cd .. 207 mv redis-4.0.2 /usr/local/redis 208 ln -s /usr/local/redis/src/* /usr/bin/ 209 redis-server 210 echo 511 > /proc/sys/net/core/somaxconn 211 echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf 212 sysctl vm.overcommit_memory=1 213 echo never > /sys/kernel/mm/transparent_hugepage/enabled 214 redis-server 修改配置文件 [root@localhost ~]# vim /usr/local/redis/redis.conf 136 daemonize yes 启动redis [root@localhost ~]# redis-server /usr/local/redis/redis.conf 查看启动情况 [root@localhost ~]# ss -pln | grep redis LISTEN 0 511 127.0.0.1:6379 *:* users:(("redis-server",7324,6))3）mysql创库建表备用
[root@localhost ~]# mysql -uroot -p123456 mysql> create database testredis; Query OK, 1 row affected (0.01 sec) mysql> use testredis Database changed mysql> create table test( -> id int not null auto_increment, -> name varchar(25) default null, -> primary key(id) -> )engine=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8; Query OK, 0 rows affected (0.02 sec) mysql> insert into test values(1,'tom'),(2,'tim'),(3,'timi'),(4,'jack'),(5,'maria'),(6,'mary'),(7,'sary'),(8,'robert'),(9,'brad'); Query OK, 9 rows affected (0.12 sec) Records: 9 Duplicates: 0 Warnings: 0 mysql> select * from test; +----+--------+ | id | name | +----+--------+ | 1 | tom | | 2 | tim | | 3 | timi | | 4 | jack | | 5 | maria | | 6 | mary | | 7 | sary | | 8 | robert | | 9 | brad | +----+--------+ 9 rows in set (0.01 sec)4）编辑php页面
[root@localhost ~]# cd /usr/local/nginx/html/ [root@localhost html]# ls 50x.html index1.php index2.php index.html index.php [root@localhost html]# mv index.php index0.php [root@localhost html]# vim index.php <? $redis = new Redis(); $redis->connect('127.0.0.1',6379) or die("Could not connect redis server"); $query = "select * from testredis.test limit 8"; for ($key = 1;$key < 9;$key++){ if(!$redis->get($key)) { $connect = mysql_connect('127.0.0.1','root','123456'); mysql_select_db(testredis); $result = mysql_query($query); while ($row =mysql_fetch_assoc($result)) { $redis->set($row['id'],$row['name']);} $myserver = "mysql";break;} else { $myserver = "redis"; $data[$key] = $redis->get($key); }} echo $myserver; echo "<br>"; for ($key = 1;$key < 9;$key++) { echo "number is <b><font color=#FF0000>$key</font></b>"; echo "<br>"; echo "name is <b><font color=#FF0000>$data[$key]</font></b>"; echo "<br>"; } ?>5）测试redis是否形成缓存
·[root@localhost html]# firefox 127.0.0.1
第一次结果如下，没有显示出来
刷新页面，结果如下图：
