build install 按需使用：
wget http://sourceforge.net/projects/pcre/files/pcre/8.33/pcre-8.33.tar.gz/download
tar -xzvf pcre-8.33.tar.gz
cd pcre-8.33
./configure
make
make install
PHP 参见 http://docs.php.net/manual/en/pthreads.installation.php
yum install libxml2
yum install libxml2-devel -y
如果编译libxml2，需要先安装zlib（如果没有安装）
yum install zlib zlib-devel
PHP 2.9.0编译通过，见G3.5备份目录
/*不再需要thread
tar -xzf pthreads-2.0.10.tgz
mv pthreads-2.0.10 php-5.6.7/ext/pthreads
./buildconf --force
rm -rf autom4te.cache/
rm aclocal.m4
./buildconf --force
./configure --help | grep pthreads
*/
./configure --prefix=/usr/local/php --enable-fpm --enable-maintainer-zts --with-mysql --with-pdo-mysql
要用pdo,在php.ini中加入： pdo_mysql.default_socket="/var/lib/mysql/mysql.sock"
make
make install
cp php.ini-production /usr/local/php/etc/php.ini
#modify /usr/local/php/etc/php-fpm.conf
cd /usr/local/php/sbin
./php-fpm -c ../etc
编译phalcon
如果找不到php环境，需要修改install文件，最后一句：
./install
/usr/local/php/bin/phpize && ./configure --enable-phalcon --with-php-config=/usr/local/php/bin/php-config && make && make install && echo -e "\nThanks for compiling Phalcon!\nBuild succeed: Please restart your web server to complete the installation"
mysql安装
yum install mysql
yum install mysql-community-server
用mysqli和curl的编译命令
yum install curl curl-devel
./configure --prefix=/usr/local/php --enable-fpm --enable-maintainer-zts --with-mysql --with-pdo-mysql --with-mysqli --with-curl
去掉--enable-maintainer-zts
./configure --prefix=/usr/local/php --enable-fpm --with-mysql --with-pdo-mysql --with-mysqli --with-curl
增加GD
./configure --prefix=/usr/local/php --enable-fpm --with-mysql --with-pdo-mysql --with-mysqli --with-curl --with-gd --with-png-dir=../libpng-1.6.29 --with-jpeg-dir=../jpeg-9b
spec要把libpng libjpeg等库打进去
/usr/local/lib/libpng*
增加openssl
一、按照openssl官网指导编译安装openssl
二、php方面，在编译时增加： --with-openssl
然后进入php源码下的 ext/openssl目录下
/usr/local/php/bin/phpize
如果提示找不到 config.m4，看看没有config0.m4 拷贝成config.m4
./configure --with-openssl --with-php-config=/usr/local/php/bin/php-config
make
make install
三、php.ini中增加
extension=openssl.so
