1 php5安装
系统环境是centos7.5
PHP官网www.php.net
当前主流版本为5.6/7.1
下载php5包：
[root@linux01 ~]# cd /usr/local/src/
[root@linux01 src]# wget http://cn2.php.net/distributions/php-5.6.32.tar.gz

解压包：
[root@linux01 src]# tar zxf php-5.6.32.tar.gz
[root@linux01 src]# cd php-5.6.32
编译php5包，configure步骤：
[root@linux01 php-5.6.32]# ./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

这样configure编译就完成了
进入make和make install
[root@linux01 php-5.6.32]# make && make install

You may want to add: /usr/local/php/lib/php to your php.ini include_path
/usr/local/src/php-5.6.32/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin

这样make && make install就编译完成
查看安装的php目录：
[root@linux01 php-5.6.32]# ls /usr/local/php/
bin etc include lib php
[root@linux01 php-5.6.32]# ls /usr/local/php/bin/
pear peardev pecl phar phar.phar php php-cgi php-config phpize
查看文件大小：
[root@linux01 php-5.6.32]# du -sh /usr/local/php/bin/php
36M /usr/local/php/bin/php
[root@linux01 php-5.6.32]# du -sh /usr/local/apache2.4/modules/libphp5.so
36M /usr/local/apache2.4/modules/libphp5.so
备注：现在把/usr/local/php/bin/php这个目录删掉是可以的，因为需要的是/usr/local/apache2.4/modules/libphp5.so这个php编译生成的模块
查看php加载的模块：
[root@linux01 php-5.6.32]# /usr/local/php/bin/php -m

不过以上的这些模块是静态的模块；实际上也可以支持扩展模块以.so结束文件
mysql，Apache服务启动了，而php是以模块存在这个lamp架构的，所以不需要启动php，php5_module这个模块很重要，删除了就不支持php解析了
[root@linux01 src]# /usr/local/apache2.4/bin/httpd -M
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.139.111. Set the 'ServerName' directive globally to suppress this message （这个不是Apache服务报错，是因为没有定义ServerName域名，修改配置文件开启域名定义就可以了）

查看php的模块文件：
[root@linux01 php-5.6.32]# ls -l /usr/local/apache2.4/modules/libphp5.so
-rwxr-xr-x 1 root root 37735360 Nov 13 20:33 /usr/local/apache2.4/modules/libphp5.so
查看Apache配置文件里增加的php模块
[root@linux01 php-5.6.32]# vim /usr/local/apache2.4/conf/httpd.conf
备注：如果不想用这个模块，在前面加上#即可注释掉
拷贝php.ini配置文件，因为前面的configure这一步定义了配置文件的路径：
./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
还有另外一种办法找配置文件的路径：
[root@linux01 php-5.6.32]# /usr/local/php/bin/php -i | less
phpinfo()

省略以下...
配置文件主要有两个：
php.ini-production -> 生产环境使用
php.ini-development -> 开发环境使用
这里选择生产环境使用的配置文件：
[root@linux01 php-5.6.32]# cp php.ini-production /usr/local/php/etc/php.ini
编译源码包时，出现的问题：
1）
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
解决办法：
[root@worker1 php-5.6.32]# yum install -y libxml2-devel
2）
checking for pkg-config... /usr/bin/pkg-config
configure: error: Cannot find OpenSSL's <evp.h>
解决办法：
[root@worker1 php-5.6.32]# yum install -y openssl-devel
3）
checking for BZip2 in default path... not found
configure: error: Please reinstall the BZip2 distribution
解决办法：
[root@worker1 php-5.6.32]# yum install -y bzip2-devel
4）
checking whether to enable JIS-mapped Japanese font support in GD... no
If configure fails try --with-vpx-dir=<DIR>
configure: error: jpeglib.h not found.
解决办法：
[root@worker1 php-5.6.32]# yum install -y libjpeg-devel
5）
checking whether to enable JIS-mapped Japanese font support in GD... no
If configure fails try --with-vpx-dir=<DIR>
checking for jpeg_read_header in -ljpeg... yes
configure: error: png.h not found.
解决办法：
[root@worker1 php-5.6.32]# yum install -y libpng-devel
6）
checking for png_write_image in -lpng... yes
If configure fails try --with-xpm-dir=<DIR>
configure: error: freetype-config not found.
解决办法：
[root@worker1 php-5.6.32]# yum install -y freetype-devel
7）
checking for mcrypt support... yes
configure: error: mcrypt.h not found. Please reinstall libmcrypt.
解决办法：
[root@worker1 php-5.6.32]# yum install -y libmcrypt-devel
2 php7安装

[root@linux01 ~]# cd /usr/local/src/

编译php7包：（与php5不同的是没有了--with-mysql=/usr/local/mysql这个选项）
[root@linux01 php-7.1.6]#./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --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
