安装pdo.so和pdo_mysql.so还有pcntl.so扩展到php中
1、下载源码，解压tar -xzvf php-5.4.20.tar.gzcd/usr/local/src/php-5.4.20/ext/pdo
/usr/local/php/bin/phpize
./configure -with-php-config=/usr/local/php/bin/php-config -enable-pdo=shared
make
make test
make install
cd/usr/local/src/php-5.4.20/ext/pdo_mysql
/usr/local/php/bin/phpize
./configure -with-php-config=/usr/local/php/bin/php-config -with-pdo-mysql=/usr/local/mysql
make
make test
make install
$ ll
总计 2.9M
-rwxr-xr-x 1 hubo hubo 155K 10-16 21:26 pdo_mysql.so
-rwxr-xr-x 1 hubo hubo 317K 10-16 21:18 pdo.so
vim/usr/local/etc/cgi/php.ini
;extension = "pdo.so"
extension = "pdo_mysql.so"
只需要打开extension = "pdo_mysql.so"扩展即可，否则会报PHP Warning:Module 'PDO' already loaded in Unknown on line 0
安装pcntl扩展时，make时 报错link: `pcntl.lo' is not a valid libtool object
make clean 后没有问题了
cd /usr/local/src/php-5.4.12/ext/pcntl/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make clean
make
make install
