sudo apt-get install autoconf g++ libxml2-dev libevent-dev libbz2-dev libcurl4-gnutls-dev libpng12-dev libjpeg62-dev libfreetype6-dev libmcrypt-dev zlib1g-dev ./configure --prefix=/usr/local/php55 --with-gettext --with-mysql=mysqlnd --with-gd --with-jpeg-dir --with-png-dir --with-curl --with-freetype-dir --enable-gd-native-ttf --enable-mbstring --enable-sockets --with-mcrypt --with-pdo-mysql=mysqlnd --enable-fpm --with-zlib --enable-zip --with-bz2 --enable-bcmath --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-pcntl
注意：
如果是RH，需要：
yum -y install curl-devel yum install libjpeg-devel yum install libpng-devel yum install freetype-devel yum install -y libmcrypt-devel.x86_64 yum install -y libxml2-devel.x86_64 yum install -y bzip2-devel.x86_64 yum install libtool-ltdl-devel (在 make的时候会出现：/usr/bin/ld: cannot find -lltdl) yum install autoconf yum install -y libtidy-devel.x86_64

编译、安装
./configure --prefix=/usr/local/php-5.3.3 --with-gettext --with-mysql=mysqlnd --with-gd --with-jpeg-dir --with-png-dir --with-curl --with-freetype-dir --enable-gd-native-ttf --enable-mbstring --enable-sockets --with-mcrypt --with-pdo-mysql=mysqlnd --enable-fpm --with-zlib --enable-zip --with-bz2 --enable-bcmath --with-tidy make make install
编译安装完成之后，还需要对php-fpm 进行配置，因为php5.3不再需要打php-fpm补丁，所以以前控制php-fpm(启动、重启)的方式需要改变。操作步骤如下：
从源码包复制：
sudo path/to/php-source/folder/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm sudo chmod a+x /etx/init.d/php-fpm
然后就可以通过 /etc/init.d/php-fpm (start|stop|force-quit|restart|reload) 进行控制
一般扩展安装

php_ini
expose_php = off error_reporting = E_ALL display_errors = On short_open_tag = On extension=memcache.so extension=xcache.so extension=solr.so bbs需要 ;log_errors = on error_log = syslog linux系统可以使用这个，把errorlog 输出到syslog中 date.timezone = Asia/Shanghai
