php从5.2.9升级到5.3.0
下载：wget http://cn.php.net/distributions/php-5.3.0.tar.gz
wget http://php-fpm.org/downloads/php-5.3.0-fpm-0.5.12.diff.gz
tar zxvfphp-5.3.0.tar.gz
gzip -cd php-5.3.0-fpm-0.5.12.diff.gz | patch -d php-5.3.0 -p1 （打fpm补丁）
cd php-5.3.0
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql

make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-production /usr/local/webserver/php/etc/php.ini
PS：在php5.3.0中与原来的php.ini-dist和php.ini-recommended对应的ini文件是php.ini-development和php.ini-production
安装php模块
tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config && make && make install
tar zxf xcache-1.3.0.tar.gz （这个版本支持php-5.3.0）
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --enable-xcache --enable-xcache-optimizer
make && make install
tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql && make && make install
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure && make && make install
tar zxvf imagick-2.2.2.tgz
cd imagick-2.2.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config && make && make install
安装完毕后，现在配置php
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini
在运行phpinfo.php总提示date参数不对。总将timezone设为Asia/Chongqing .最后，要修改php.ini的开发版本的timezone设置。phpinfo.php所显示的date参数才正常
vim /usr/local/webserver/php/etc/php.ini
date.timezone = Asia/Shanghai默认为空，现在改为Asia/Shanghai
配置xcache
vim /usr/local/webserver/php/etc/php.ini 在最后添加
zend_extension = /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20090626/xcache.so
xcache.admin.user = "bshrer"
;xcache.admin.pass = md5($yourpasswd)
xcache.admin.pass = "e10adc3949ba59abbe56e057f20f883e"
xcache.cacher = On
xcache.shm_scheme = "mmap"
xcache.size = 256M
;cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.count = 4
xcache.slots = 8k
xcache.ttl = 0
xcache.gc_interval = 0
xcache.var_size = 2M
;cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.var_count = 4
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.readonly_protection = Off
创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vim /usr/local/webserver/php/etc/php-fpm.conf
All relative paths in this config are relative to php's install prefix
Pid file
/usr/local/webserver/php/logs/php-fpm.pid
Error log file
/usr/local/webserver/php/logs/php-fpm.log
Log level
notice
When this amount of php processes exited with SIGSEGV or SIGBUS ...
10
... in a less than this interval of time, a graceful restart will be initiated.
Useful to work around accidental curruptions in accelerator's shared memory.

5s
Set to 'no' to debug fpm
yes
Name of pool. Used in logs and stats.
default

Set listen(2) backlog
-1
Set permissions for unix socket, if one used.
In Linux read/write permissions must be set in order to allow connections from web server.
Many BSD-derrived systems allow connections regardless of permissions.
0666
Additional php.ini defines, specific to this pool of workers.
/usr/sbin/sendmail -t -i
1
Unix user of processes
www
Unix group of processes
www
Process manager settings
Sets style of controling worker process count.
Valid values are 'static' and 'apache-like'
static
Sets the limit on the number of simultaneous requests that will be served.

Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi
Used with any pm_style.
128
Settings group for 'apache-like' pm style
Sets the number of server processes created on startup.
Used only when 'apache-like' pm_style is selected
20
Sets the desired minimum number of idle server processes.
Used only when 'apache-like' pm_style is selected
5
Sets the desired maximum number of idle server processes.
Used only when 'apache-like' pm_style is selected
35
The timeout (in seconds) for serving a single request after which the worker process will be terminated
Should be used when 'max_execution_time' ini option does not stop script execution for some reason
'0s' means 'off'
0s
The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
'0s' means 'off'
0s
The log file for slow requests
logs/slow.log
Set open file desc rlimit
51200
Set max core size rlimit
0
Chroot to this directory at the start, absolute path
Chdir to this directory at the start, absolute path
Redirect workers' stdout and stderr into main error log.
If not set, they will be redirected to /dev/null, according to FastCGI specs
yes
How much requests each process should execute before respawn.
Useful to work around memory leaks in 3rd party libraries.
For endless request processing please specify 0
Equivalent to PHP_FCGI_MAX_REQUESTS
102400
Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.
Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

Pass environment variables like LD_LIBRARY_PATH
All $VARIABLEs are taken from current environment
$HOSTNAME
/usr/local/bin:/usr/bin:/bin

/tmp
$OSTYPE
$MACHTYPE

启动php-cgi进程
ulimit -SHn 51200
/usr/local/webserver/php/sbin/php-fpm start
