1、下载源码，解压tar -xzvf php-5.4.20.tar.gz
cd /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
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
make install
[hubo@test15169x /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525]$ 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"
只需要打开
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
