php-5.4.22 编译

configure: error: xml2-config not found. Please check your libxml2 installation

参考文章：http://blog.youkuaiyun.com/anljf/article/details/6981247

 

安装php时的报错

checking libxml2 install dir... no
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.

 

检查是否安装了libxm包

[root@XKWB3403 php-5.3.8]# rpm -qa |grep  libxml2
libxml2-2.6.26-2.1.12
libxml2-python-2.6.26-2.1.12

 

重新安装libxml2和libxml2-devel包

yum install libxml2

yum install libxml2-devel -y

 

安装完之后查找xml2-config文件是否存在

[root@XKWB3403 php-5.3.8]# find / -name "xml2-config"
/usr/bin/xml2-config

 

如果存在的话重新安装php

[root@XKWB3403 php-5.3.8]# ./configure

 

安装成功的标志是

 

之后再进行编译

make && make install

据说php5.4要比此前各版本的php快不少，所以有必要安装来测试一下（国内比较流行的一些php程序比如discuz等等对php5.4的支持貌似还不太友好，所以站长朋友们还是要慎重升级）。下面是在64位centos6.1上面编译安装的笔记，仅供参考。

1、下载

wget http://cn.php.net/get/php-5.4.8.tar.gz/from/this/mirror
wget http://pecl.php.net/get/memcache-2.2.7.tgz
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
wget https://github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz
wget https://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
wget "http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0"
wget "http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.8.tar.gz?modtime=1194463373&big_mirror=0"
wget ftp://ftp.kddlabs.co.jp/graphics/ImageMagick/ImageMagick.tar.gz
wget "http://downloads.sourceforge.net/mhash/mhash-0.9.9.9.tar.gz?modtime=1175740843&big_mirror=0"
wget http://pecl.php.net/get/imagick-3.1.0RC2.tgz
2、另外一些准备工作

yum install ncurses-devel libxml2-devel bzip2-devel libcurl-devel curl-devel libjpeg-devel libpng-devel freetype-devel net-snmp-devel -y

ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/ （假定mysql已经安装。不加这个的话后面编译的时候可能会出错）

3、还有这些准备工作（编译一些php需要用到的支持库）

tar xzvf libic*
cd libic*
./configure --prefix=/usr/local
make
make install
cd ..

tar xzvf libmcry*
cd libmcry*
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure
--enable-ltdl-install
make
make install
cd ../../

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

4、开始编译安装php

tar xvzf php-5.4.*.tar.gz cd php-5.4.*

./configure --prefix=/usr/local/php --with-config-file-path=/etc \
--with-mysql=/usr/local/mysql/ --with-mysqli=/usr/local/mysql/bin/mysql_config \
--with-pdo-mysql=/usr/local/mysql/ --with-iconv-dir=/usr/local --enable-fpm \
--disable-phar --with-fpm-user=www --with-fpm-group=www --with-pcre-regex \
--with-zlib --with-bz2 --enable-calendar --with-curl --enable-dba --with-libxml-dir \
--enable-ftp --with-gd --with-jpeg-dir --with-png-dir --with-zlib-dir --with-freetype-dir \
--enable-gd-native-ttf --enable-gd-jis-conv --with-mhash --enable-mbstring --with-mcrypt \
--enable-pcntl --enable-xml --disable-rpath --enable-shmop --enable-sockets --enable-zip \
--enable-bcmath --with-snmp --disable-ipv6

make ZEND_EXTRA_LIBS='-liconv'

make test

make install

cp php.ini-production /etc/php.ini
5、编译安装php的一些扩展模块

tar zxvf memcache-*.tgz
cd memcache-*/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar xzvf libevent*
cd libevent*
./configure --prefix=/usr/local
make
make install
cd ..

tar xvzf memcached-*.gz
cd memcached-*
./configure --with-libevent=/usr/local --prefix=/usr/local/memcached
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-*/
./configure
make
make install
cd ../

tar zxvf imagick-*.tgz
cd imagick-*/
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/ /usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

6、修改php的一些参数配置

vi /etc/php.ini
增加这些：

extension_dir = /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/
extension = "memcache.so"
extension = "imagick.so"
修改这些：

cgi.fix_pathinfo=0

disable_functions = exec,system,phpinfo,eval,passthru,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,fsocket,fsockopen,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server（有关禁用函数的说明，参看上一篇日志：一些比较危险的php函数）
