php安装中出现的问题解决
php安装：
1./configure –prefix=/usr/local/php –with-apxs2=/home/apache/bin/apxs –with-zlib-dir –with-libxml-dir=/usr/local/libxml2/ –with-gd –with-freetype –with-jpeg –with-png –enable-mbstring –with-mysql=/usr/local/mysql/ –with-mysqli=/usr/local/mysql/bin/mysql_config –enable-gd-native-ttf
搞gaodaima代码–with-gettext=/usr/local/gettext/ –enable-magic-quotes –enable-sockets
需要php支持图片需要gd库
由于操作系统自带了gd png jpeg 库等，没法指定dir 直接用–with-jpeg这样的形式。
2.make install时出现以下错误:
Installing PHP SAPI module: apache2handler
/usr/share/apache2/build/instdso.sh SH_LIBTOOL=’/usr/share/apr-1.0/build/libtool’ libphp5.la /usr/lib/apache2/modules
/usr/share/apr-1.0/build/libtool –mode=install cp libphp5.la /usr/lib/apache2/modules/
libtool: install: cp .libs/libphp5.so /usr/lib/apache2/modules/libphp5.so
libtool: install: cp .libs/libphp5.lai /usr/lib/apache2/modules/libphp5.la
libtool: install: warning: remember to run `libtool –finish /home/hcc/php-5.2.13/libs’
chmod 644 /usr/lib/apache2/modules/libphp5.so
apxs:Error: Activation failed for custom /etc/apache2/httpd.conf file..
apxs:Error: At least one `LoadModule’ directive already has to exist..
make: *** [install-sapi] Error 1
实际上httpd.conf已经存在。不知道为什么出现以上错误，采用了以下方法，先备份httpd.conf
然后重新建一个httpd.conf
内容
#LoadModule directive to aid module installations
#LoadModule dummy_module /usr/lib/apache2/modules/mod_dummy.so
这样就成功安装
3.解决了php安装后，发现php不支持jpeg，但是在上述的配置过程中已经加上了–with-jpeg，并且libjpeg的rpm也是安装的，但是始终是无法支持，只好重新安装jpeg库
下载jpegv6
ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/jpeg-6b.tar.gz
编译安装：./configure –prefix=/usr/local/jpeg –enable-shared
然后在安装php
/configure –prefix=/usr/local/php –with-apxs2=/home/apache/bin/apxs –with-zlib-dir –with-libxml-dir=/usr/local/libxml2/ –with-gd –with-freetype –with-jpeg-dir=/usr/local/jpeg –with-png –enable-mbstring –with-mysql=/usr/local/mysql/ –with-mysqli=/usr/local/mysql/bin/mysql_config –enable-gd-native-ttf –with-gettext=/usr/local/gettext/ –enable-magic-quotes –enable-sockets
重新编译安装即可支持jpeg
