php5.3在centos5.5下安装

 rpm -e php-devel-5.3.6-1.w5
  rpm -e php-5.3.6-1.w5
  rpm -e php-cli-5.3.6-1.w5
  rpm -e php-gd-5.3.6-1.w5
 rpm -e php-common-5.3.6-1.w5

yum install libxml2 libxml2-devel

下载新的php.5.3.8.tar.gz

解压

  ./configure  --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-libxml-dir=/usr/local/include/libxml2/libxml --enable-mbstring --with-gd --with-zlib --without-iconv --with-conf-path=/etc/
提示
  通过查找libmysqlclient,发现是在/usr/lib64/mysql/目录内的libmysqlclient.so.15.0.0做的软连接,PHP默认是去的 /usr/lib/搜索,所以没有找到.找到问题了就好解决了.
解决办法就是:
    cp -rp /usr/lib64/mysql/libmysqlclient.so.15.0.0 /usr/lib/libmysqlclient.so
    重新编译
make
make test
make install

cp php.ini-production /usr/local/php/lib/php.ini
vim /etc/php.ini (增加/usr/local/php/lib/php到include_path)
执行/usr/sky/soft/php/php-5.3.8/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin

pecl install mongo

pear config-set php_ini /usr/local/php/lib/php.ini
pecl config-set php_ini /usr/local/php/lib/php.ini

如果用编译方式
phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make &make install
