mysql_with_redis_with_php_with_nginx大结合：
本版本mysql使用系统自带的版本
redis，php，nginx等软件及依赖性见官网及pkgs.org
server1.example.com :172.25.33.1 mysql
server2.example.com : 172.25.33.2 nginx +php
server3.example.com :172.25.33.3 redis

server1上安装mysql-server
server2上安装nginx和php及其扩展。
nginx所在的服务器需要和mysql，redis等沟通，相当于桥梁的作用，所以需要和他们相关的插件：
php-mysql
php-redis
[root@server2 redis]# ll phpredis-master.zip
-rwxr-xr-x 1 root root 83734 Oct 21 00:18 phpredis-master.zip
[root@server2 redis]# unzip phpredis-master.zip
-bash: unzip: command not found
安装unzip解压：
[root@server2 phpredis-master]# ls
common.h debian.control mkdeb-apache2.sh redis_session.c
config.m4 igbinary php_redis.h redis_session.h
CREDITS library.c README.markdown serialize.list
debian library.h redis.c tests
发现其中并没有可执行文件，需要php的开发包php-devel
[root@server2 redis]# yum install -y php-devel-5.3.3-38.el6.x86_64.rpm
然后在当前目录下执行phpize
phpize 的作用是侦测当前的php环境，并根据环境生成一个configure。
[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
编译安装：
编译完成后并不会生成redis.ini文件，需要自己手动生成，php.ini 在php-common的目录下边：[root@server2 modules]# rpm -ql php-common
/etc/php.d
/etc/php.d/curl.ini
/etc/php.d/fileinfo.ini
/etc/php.d/json.ini
/etc/php.d/phar.ini
/etc/php.d/zip.ini
/etc/php.ini
[root@server2 php.d]# cp mysql.ini redis.ini
[root@server2 php.d]# vim redis.ini
[root@server2 php.d]# pwd
/etc/php.d
[root@server2 php.d]# cat redis.ini
; Enable mysql extension module
extension=redis.so
或者直接将redis.ini写入php.ini中。
重起php-fpm，发现redis插件已经插入
[root@server2 php.d]# php -m |grep redis
redis
[root@server2 redis]# rpm -qa |grep php
php-cli-5.3.3-38.el6.x86_64
php-fpm-5.3.3-38.el6.x86_64
php-mysql-5.3.3-38.el6.x86_64
php-common-5.3.3-38.el6.x86_64
php-5.3.3-38.el6.x86_64
php-pdo-5.3.3-38.el6.x86_64
修改nginx的配配置文件：
[root@server2 redis]# !vi
vim /etc/nginx/conf.d/default.conf
8 location / {
9 root /usr/share/nginx/html;
10 index index.php index.html index.htm;
11 }
28 #pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
29
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 }
在/usr/share/nginx/html下编写php的测试页：
[root@server2 html]# ls
50x.html index.html index.php
[root@server2 html]# cat index.php
<?php
phpinfo()
?>
启动php-fpm服务。
[root@server2 html]# service php-fpm start
Starting php-fpm: [ OK ]
重起nginx服务
[root@server2 html]# service nginx restart
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
然后即可通过网页访问php的测试页：
***注意：在nginx的配置文件中定义的首页是有顺序的。
在server3.example.com 上安装redis
解压，直接make&& make install
有写情况下可能需要安装环境：(根据提示走)
jemalloc-3.6.0-1.el6.x86_64.rpm
jemalloc-devel-3.6.0-1.el6.x86_64.rpm
然后进入当前目录的utils
安装redis
[root@server3 utils]# ./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
然后一路回车
修改redis-server的配置文件：
[root@server3 utils]# vim /etc/redis/6379.conf
~~~~~~~~~~
62 bind 0.0.0.0
重起
[root@server3 utils]# /etc/init.d/redis_6379 restart
Stopping ...
Redis stopped
Starting Redis server...
[root@server3 utils]# netstat -antlp |grep redis
tcp 0 0 0.0.0.0:6379 0.0.0.0:* LISTEN 4534/redis-server 0
redis监听在所有端口，
测试：
数据库和php的连接需要程序的支持：
[root@server2 redis]# cat test.php
<?php
$redis = new Redis();
$redis->connect('172.25.33.3',6379) or die ("could net connect redis server");
# $query = "select * from test limit 9";
$query = "select * from test";
for ($key = 1; $key < 10; $key++)
{
if (!$redis->get($key))
{
$connect = mysql_connect('172.25.33.1','redis','westos');
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 $myserver;
echo "<br>";
for ($key = 1; $key < 10; $key++)
{
echo "number is <b><font color=#FF0000>$key</font></b>";
echo "<br>";
echo "name is <b><font color=#FF0000>$data[$key]</font></b>";
echo "<br>";
}
?>
[root@server2 redis]#
将这个页面作为php的首页。
[root@server2 redis]# cp test.php /usr/share/nginx/html/index.php
cp: overwrite `/usr/share/nginx/html/index.php'? y
在server1.example.com中插入数据
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 |
+----+-------+
为index.php中的用户授权
mysql> grant update on test.* to redis@'172.25.33.2' identified by 'westos' ;
在浏览器上测试：
即可得到数据库响应的数据
此时有一个很大的缺陷：内容的一致性，redis在得到结果后，如果查找内容在其内存中存在，那么，他就不会返回数据库取数据，会造成数据的不一致性，所以需要添加一个触发器：
配置gearman 实现数据同步
gearman 是一个支持分布式的任务分发框架
gearman job server 作为gearman的核心程序，需要编译安装并以守护进程形式运行在后台。
gearman client 任务的请求者
gearman worker 任务执行着
在nginx所在的服务器安装gearman
[root@server2 redis]# yum install -y gearmand-1.1.8-2.el6.x86_64.rpm
libgearman-1.1.8-2.el6.x86_64.rpm
[root@server2 redis]# yum install -y libgearman-devel-1.1.8-2.el6.x86_64.rpm libevent-devel-1.4.13-4.el6.x86_64.rpm libevent-headers-1.4.13-4.el6.noarch.rpm libevent-doc-1.4.13-4.el6.noarch.rpm
安装php的gearman的扩展
安装开发包。系统自带
[root@server2 redis]# yum install -y db*-devel
编译安装gearman job server
[root@server2 redis]# tar -xf gearman-1.1.2.tgz
[root@server2 redis]# cd gearman-1.1.2
[root@server2 gearman-1.1.2]# ls

或
[root@server2 php.d]# grep ^extension /etc/php.ini
extension = gearman.so
重起Php-fpm
在server1.example.com添加udf用户自定义函数
由于要对数据库进行操作，所以要安装数据库开发包
[root@server1 lib_mysqludf_json-master]# unzip lib_mysqludf_json-master.zip
[root@server1 lib_mysqludf_json-master]# cd lib_mysqludf_json-master
[root@server1 lib_mysqludf_json-master]# yum install -y mysql-devel
[root@server1 lib_mysqludf_json-master]# gcc $(mysql_config --cflags) -shared -fPIC -o lib_mysqludf_json.so lib_mysqludf_json.c
登陆数据库，使用mysql> show global variables like 'plugin_dir';
+---------------+-------------------------+
| Variable_name | Value |
+---------------+-------------------------+
| plugin_dir | /usr/lib64/mysql/plugin |
+---------------+-------------------------+
1 row in set (0.00 sec)
找到数据库插件所在的位置
[root@server1 lib_mysqludf_json-master]# ls
lib_mysqludf_json.c lib_mysqludf_json.so README.md
lib_mysqludf_json.html lib_mysqludf_json.sql
[root@server1 lib_mysqludf_json-master]# cp lib_mysqludf_json.so /usr/lib64/mysql/plugin/
将用户自定义函数考入插件库
安装gearman-mysql用户自定义函数：
[root@server1 redis]# yum install -y libgearman-1.1.8-2.el6.x86_64.rpm libgearman-devel-1.1.8-2.el6.x86_64.rpm libevent-devel-1.4.13-4.el6.x86_64.rpm libevent-doc-1.4.13-4.el6.noarch.rpm libevent-headers-1.4.13-4.el6.noarch.rpm
解压gearman-mysql-udf-0.6
编译安装
[root@server1 gearman-mysql-udf-0.6]# ./configure --with-mysql=/usr/bin/mysql_config --libdir=/usr/lib64/mysql/plugin/
make && make install
注册用户自定义函数：
CREATE FUNCTION json_object RETURNS STRING SONAME 'lib_mysqludf_json.so';

编写gearman 的worker端
[root@server2 redis]# cat worker.php
<?php
$worker = new GearmanWorker();
$worker->addServer();
$worker->addFunction('syncToRedis', 'syncToRedis');
$redis = new Redis();
$redis->connect('172.25.33.3', 6379);
