安装PHP5
PHP官网www.php.net
当前主流版本为5.6/7.1
cd /usr/local/src/ wget http://cn2.php.net/distributions/php-5.6.30.tar.gz tar zxf php-5.6.30.tar.gz cd php-5.6.30 ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
prefix安装目录 with-apxs2是apache工具，自动把扩展模块放到moudles目录，且在配置文件加上一行，配置成功 with-config-file-path指定配置文件所在路径 with-mysql指定MySQL路径 with-pdo-mysql with-mysqli 指定MySQL库 路径等 目的为了让php支持MySQL 后续为一些Php需要的模块
安装报错：
1. configure: error: xml2-config not found. Please check your libxml2 installation.

2. configure: error: Cannot find OpenSSL's <evp.h>
[root@chy002 php-5.6.30]# yum install -y openssl-devel.i686
3. configure: error: libcrypto not found!
出现这个问题是因为问题2的openssl包安装错了，应该是x86_64的
4. configure: error: Please reinstall the BZip2 distribution
[root@chy002 php-5.6.30]# yum install -y bzip2-devel.x86_64
5. configure: error: jpeglib.h not found.
[root@chy002 php-5.6.30]# yum install -y libjpeg-devel
6. configure: error: png.h not found.
[root@chy002 php-5.6.30]# yum install -y libpng-devel.x86_64

[root@chy002 php-5.6.30]# yum install -y freetype-devel.x86_64
8. configure: error: mcrypt.h not found. Please reinstall libmcrypt.
[root@chy002 php-5.6.30]# yum install -y libmcrypt-devel.x86_64
make && make install
cp php.ini-production /usr/local/php/etc/php.ini
主要的二进制文件
[root@chy002 php-5.6.30]# du -sh /usr/local/php/bin/ 71M /usr/local/php/bin/
php和apache结合的模块
[root@chy002 php-5.6.30]# du -sh /usr/local/apache2.4/modules/libphp5.so 37M /usr/local/apache2.4/modules/libphp5.so
php所有静态模块显示
[root@chy002 php-5.6.30]# /usr/local/php/bin/php -m [PHP Modules] bz2 Core ... ... xml xmlreader xmlwriter zlib [Zend Modules]
php需要启动吗？
可以看下apache的模块 ，发现最后一个就是Php模块，所以不用启动，存在该模块即可。apache配置文件可以配置加载某些模块。
