公司的项目用的框架（非目前的主流框架）不支持PHP5.4以上的版本，导致在迁移项目的时候就需要指定特定的版本进行安装，故将安装的过程记录下来，以便后续的翻阅，遇到坑也可以查看。
大致是信息：
php 5.4.45
nginx 1.14.2
mysql 5.6
centos7
准备工作：
先安装如下依赖包
yum -y install gcc automake autoconf libtool make gcc-c++ glibc
yum -y install libmcrypt-devel mhash-devel libxslt-devel \
libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel \
zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel \
ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel \
krb5 krb5-devel libidn libidn-devel openssl openssl-devel
创建用户组和用户
groupadd www
useradd -r www -g www
下载并解压php
cd /usr/local/src
yum install wget
wget https://museum.php.net/php5/php-5.4.45.tar.gz
tar zxvf php-5.4.4.tar.gz
cd php-5.4.4
配置configure
因为环境问题导致的项目跑不起来，或者出错的情况还是比较的多，所以我尽量和线上的配置查不多吧。
./configure --prefix=/usr/local/php --with-pdo-pgsql
--with-zlib-dir --with-freetype-dir --enable-mbstring
--with-libxml-dir=/usr --enable-soap --enable-calendar
--with-curl --with-mcrypt=/usr/local/bin/libmcrypt
--with-gd --with-pgsql --disable-rpath --enable-inline-optimization
--with-bz2 --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --enable-exif
--enable-bcmath --with-mhash --enable-zip --with-pcre-regex
--with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --enable-gd-native-ttf
--with-openssl --with-fpm-user=www --with-fpm-group=www
--enable-ftp --with-gettext --with-xmlrpc --with-xsl --enable-fpm
--with-iconv --with-xpm-dir=/usr/bin --enable-pdo --with-mysql=mysqlnd
--with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
运行上面的configure发现报错了：
checking for mcrypt support... yes
configure: error: mcrypt.h not found. Please reinstall libmcrypt.
那就去解决咯
wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz
tar -zxvf libmcrypt-2.5.7.tar.gz
cd libmcrypt-2.5.7
./configure --prefix=/usr/local/bin/libmcrypt
make && make install
然后配置configure为：
--with-mcrypt=/usr/local/bin/libmcrypt
然后还是报错：
configure: error: libXpm.(a|so) not found.
那就安装咯：
yum -y install libxpm-dev
然后并没有预期的解决，好伤心，只能接着一顿操作。
这解决的方法大多不生效，看这个可以 文章https://www.cnblogs.com/wusong/p/4694938.html
大致内容：
centos 6.5
安装php时老是报错，找了很久答案都是千篇一律且不起作用，最后找到一个答案，特记录在此
configure: error: libXpm.(a|so) not found.
解决方法：
1，按网络上说的执行yum -y install libXpm-devel，表示最新版本已存在，无需安装。
2，查找usr/lib，根本就是没有libXpm.(a|so) 文件，也没有所谓的/usr/lib/x86_64-linux-gnu目录
3，查找usr/lib64,终于看到好多libxpm文件。于是软链接 ln -s /usr/lib64/libXpm.so* /usr/lib/
再执行，搞定。
其实原因：
configure一般的搜索编译路径为/usr/lib/下,因为php默认就在/usr/lib/下找相关库文件
linkto: http://blog.csdn.net/buutterfly/article/details/5630203
so,
注： 主机是x64平台，
ln -s /usr/lib64/libXpm.so* /usr/lib/
并且编译时指定， --with-xpm-dir=/usr/lib64/x11
注意我的编译时指定是--with-xpm-dir=/usr/lib64/x11
最后我在/usr/lib下面查了为x86_64-linux-gnu目录确实没有，就按使用了他说的软连接，在查看软连接生效，然后在 configure 设置 --with-xpm-dir=/usr/lib
然后接着configure，但是又又又报错啦：
configure: error: Cannot find libpq-fe.h.
Please specify correct PostgreSQL installation path
那就接着执行咯：
yum -y install postgresql-devel
然后接着执行configure，成功信息如下：

编译安装
那就来执行编译的make和make install，这可以分开执行也可以一起执make && make install
我分开执行的，想看下执行之后输出的内容
执行make后的内容：
Generating phar.php
Generating phar.phar
PEAR package PHP_Archive not installed: generated phar will require PHP's phar extension be enabled.
clicommand.inc

phar.inc
Build complete.
Don't forget to run 'make test'.
执行make install之后的内容

You may want to add: /usr/local/php/lib/php to your php.ini include_path
/usr/local/src/php-5.4.45/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin
ln -s -f /usr/local/php/bin/phar.phar /usr/local/php/bin/phar

配置php
[root@localhost php-5.4.45]# find / -name php.ini-development
/usr/local/src/php-5.4.45/php.ini-development
如果发现没有php.ini文件可以参考：
有些人./configure的时候设置了这个文件--with-config-file-path=/etc
但是我没有配置，应该有默认位置，然后就百度，发现了这个文章：https://www.cnblogs.com/jie-fang/p/10677565.html
那么参考那篇文章就往下操作：
[root@localhost php]# php -r "phpinfo();" | grep 'php.ini'
-bash: php: 未找到命令
[root@localhost php]# /usr/local/php/bin/php -r "phpinfo();" | grep 'php.ini'
Configuration File (php.ini) Path => /usr/local/php/lib
[root@localhost php-5.4.45]# cp php.ini-development /usr/local/php/lib/php.ini
[root@localhost ~]# cd /usr/local/php/etc/
[root@localhost etc]# cp php-fpm.conf.default php-fpm.conf
[root@localhost ~]# cd /usr/local/php/etc/php-fpm.d
[root@localhost php-fpm.d]# cp www.conf.default www.conf
测试PHP环境
- 安装完成执行：
./bin/php -m， 返回php安装的扩展 - 也可以测试：
vim test.php,里面写上内容可以是echo 'hello';等内容，执行./bin/php test.php
报错
