安装nginx+php+fastcgi+memcache+xcache/eaccelerator/apc

rpm -ivh epel-release-5-3.noarch.rpm

yum list

yum install nginx gcc openssl-devel pcre-devel zlib-devel mysql-server mysql-devel libmcrypt-devel libxml2-devel libtool-ltdl-devel

gzip -cd php-5.2.9-fpm-0.5.10-unofficial.diff.gz |patch -d php-5.2.9 -p1

cd php-5.2.9

./configure --prefix=/usr/local/php --enable-fastcgi --enable-fpm --with-mysql --with-mcrypt --with-zlib

make && make install

cp /usr/local/php/sbin/php-fpm /etc/init.d

vim /etc/init.d/php-fpm

# chkconfig: - 85 15

# description: php-fpm

vim /usr/local/php/etc/php-fpm.conf

fpm安装完成后 (其实是php的编译前打上fpm的补丁,在编译的时候增加fpm的参数)

要将 Unix user of processes

<value name="user">nobody</value>

Unix group of processes

<value name="group">nobody</value>

这2个的注释去掉,不然就会提示

root@yuan:/server/nginx/html# /server/php/sbin/php-fpm start

Starting php_fpm Sep 11 17:12:07.248390 [ERROR] fpm_unix_conf_wp(), line 124: please specify user and group other than root, pool 'default'

done

vim /etc/nginx/nginx.conf

取消注释

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

include fastcgi_params;

}

vim /etc/nginx/fastcgi_params

加一条fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

service nginx restart

先安装libevent：

tar zxvf libevent-1.2.tar.gz

cd libevent-1.2

./configure --prefix=/usr

make

make install

Memcached 服务端安装：(源码包官方网站下载)

系统命令

tar xvf memcached-1.2.6.tar.gz

cd memcached-1.2.6

./configure --prefix=/usr/local/memcached --with-libevent=/usr/

make

make install

然后就可以启动memcached的守护进程了：

系统命令

/usr/local/memcached/bin/memcached -p 11211 -l 127.0.0.1 -d -u nobody -P /var/run/memcached.pid -m 64M -c 1024

php中memcache扩展组件的安装：

系统命令

tar xvf memcache-3.0.3.tgz

cd memcache-3.0.3

/usr/local/php5/bin/phpize

./configure --with-php-config=/usr/local/php5/bin/php-config --enable-memcache

make

make install

php中memcache扩展组件的安装：

系统命令

tar xvf memcache-3.0.3.tgz

cd memcache-3.0.3

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config --enable-memcache

make

make install

按照我的环境，编译出来的memcache.so保存在 /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ 目录下，如果你的环境不一样，你得根据自己情况修改你的php.ini了。

接着要做的工作就是让php加载这个扩展，编辑你的php.ini，在适当位置（通常是最后，也可以是独立的一个ini文件）加入如下行：

extension=memcache.so

然后重启你的phpfastcgi进程或者apache，运行一个phpinfo()来确认一下，正常的话你应该可以看到这个了：memcache

php-memcache的简单使用举例：

<?php

$memcache = new Memcache;

$memcache->connect('127.0.0.1','11211');

$memcache->setCompressThreshold(20000, 0.2);

echo $memcache->getVersion();

$test = array(1,2,3,4,5,'abcde');

if($memcache->get('test')){

print_r($memcache->get('test'));

echo "\n";

echo 'cached';

echo "\n";

}else{

$memcache->set('test',$test,0,30);

echo 'no cache';

echo "\n";

}

?>

四 配置XCache

1、安装xcache模块

wget http://xcache.lighttpd.net/pub/Releases/1.2.2/xcache-1.2.2.tar.gz
tar -xvzf xcache-1.2.2.tar.gz

cd xcache-1.2.2

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config --enable-xcache --enable-xcache-optimizer

make

make install

2、计算密码的md5值

echo -n "password"|md5sum

5f4dcc3b5aa765d61d8327deb882cf99

3、配置XCache

;注： zend_extension,用来加载zend的扩展，是绝对路径,

extension是相对路径，相对于extension_dir的相对路径，非zend扩展

如果你更改路径以后，一定要apachectl stop后再start，而不要restart。

vi /usr/local/php/etc/php.ini

添加：

[xcache-common]

zend_extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so

[xcache.admin]

; Change xcache.admin.user to your preferred login name

xcache.admin.user = "admin"

; Change xcache.admin.pass to the MD5 fingerprint of your password

; Use md5 -s "your_secret_password" to find the fingerprint

xcache.admin.pass = "5f4dcc3b5aa765d61d8327deb882cf99"

[xcache]

; Change xcache.size to tune the size of the opcode cache

xcache.size = 24M

xcache.shm_scheme = "mmap"

xcache.count = 2

xcache.slots = 8K

xcache.ttl = 0

xcache.gc_interval = 0

; Change xcache.var_size to adjust the size of variable cache

xcache.var_size = 8M

xcache.var_count = 1

xcache.var_slots = 8K

xcache.var_ttl = 0

xcache.var_maxttl = 0

xcache.var_gc_interval = 300

xcache.test = Off

xcache.readonly_protection = On

xcache.mmap_path = "/tmp/xcache"

xcache.coredump_directory = ""

xcache.cacher = On

xcache.stat = On

xcache.optimizer = Off

[xcache.coverager]

xcache.coverager = On

xcache.coveragedump_directory = ""

5、重启PHP模块

正常load之后,

在phpinfo显出的信息内

Zend这快应该会加上XCache的内容

6、另外两种加速模块：

在我们的测试中，效果都要好于xcache，这3中加速不能同时存在两种，有冲突。

6.1 apc

wget http://pecl.php.net/get/APC-3.0.19.tgz
cd APC-3.0.19

/usr/local/php/bin/phpize

./configure --enable-apc --enable-apc-mmap --with-apxs=/EBS/apache/bin/apxs --with-php-config=/EBS/php/bin/php-config

make

make install

6.2 eaccelerator

wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.zip
cd eaccelerator-0.9.5.3

/usr/local/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/EBS/php/bin/php-config

make

make install

vi php.ini

zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="16"

eaccelerator.cache_dir="/tmp/eaccelerator"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="0"

eaccelerator.shm_prune_period="0"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

五、使用nginx对应多台facgi服务器

思路：前端一台nginx，用于做为负载均衡和处理静态页面。利用nginx的upstream模块来将php请求分发到后段的php-fpm服务器上。

后端多台php-fpm的服务器，只起php-fpm服务来处理php。

这样做减少了php-fpm上的nginx服务，相当于少了一层。
