1、下载php源码
wget http://am1.php.net/get/php-7.2.4.tar.gz/from/this/mirror
重命名: mv mirror php-7.2.4.tar.gz
使用 tar zxvf php-7.2.4.tar.gz 解压
如果解压重命名后发现 使用tar命令出错如下: Child returned status 1 这种，应该是wget下载的时候出错，或者我们的链接地址有错，导致文件不完整，我们从官网上找一个可以下载的或者我们下载好php源码上传到服务器上面，也可以
2、 配置
cd php-7.2.4/
然后进行配置相关命令:
./configure \
--prefix=/usr/local/php7 \
--exec-prefix=/usr/local/php7 \
--bindir=/usr/local/php7/bin \
--sbindir=/usr/local/php7/sbin \
--includedir=/usr/local/php7/include \
--libdir=/usr/local/php7/lib/php \
--mandir=/usr/local/php7/php/man \
--with-config-file-path=/usr/local/php7/etc \
--with-mysql-sock=/var/lib/mysql/mysql.sock \
--with-mcrypt=/usr/include \
--with-mhash \
--with-openssl \
--with-mysql=shared,mysqlnd \
--with-mysqli=shared,mysqlnd \
--with-pdo-mysql=shared,mysqlnd \
--with-gd \
--with-iconv \
--with-zlib \
--enable-zip \
--enable-inline-optimization \
--disable-debug \
--disable-rpath \
--enable-shared \
--enable-xml \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-mbregex \
--enable-mbstring \
--enable-ftp \
--enable-gd-native-ttf \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-soap \
--without-pear \
--with-gettext \
--enable-session \
--with-curl \
--with-jpeg-dir \
--with-freetype-dir \
--enable-opcache \
--enable-redis \
--enable-fpm \
--enable-fastcgi \
--with-fpm-user=www \
--with-fpm-group=www \
--without-gdbm \
--disable-fileinfo
出现报错:
缺少libxml2相关：
configure: error: libxml2 not found. Please check your libxml2 installation.
解决:
yum -y install libxml2-devel
重新执行上面配置:
出现: configure: error: Cannot find OpenSSL's <evp.h>
解决: yum install openssl-devel
出现: checking for cURL 7.10.5 or greater... configure: error: cURL version 7.10.5 or later is required to compile php with cURL support
解决: yum -y install curl-devel
出现: configure: error: jpeglib.h not found.
解决: yum install libjpeg-devel
出现: configure: error: freetype-config not found.
yum -y install freetype-devel
解决过上面报错信息，我们重新执行一下上面./configure 的所有命令:
出现 Thank you for using PHP. 证明我们配置成功了
configure: creating ./config.status
creating main/internal_functions.ccreating main/internal_functions_cli.c

//这里会出现上面的warning 是因为configure命令没有识别出来，这个configure大家根据自己需求进行配置，我是参考其他人的使用的
3、编译和编译安装
make && make install
最后结果如下:
Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-non-zts-20170718/
Installing PHP CLI binary: /usr/local/php7/bin/
Installing PHP CLI man page: /usr/local/php7/php/man/man1/

ln -s -f phar.phar /usr/local/php7/bin/phar
Installing PDO headers: /usr/local/php7/include/php/ext/pdo/
[root@localhost php-7.2.4]# echo $?
0证明我们安装成功了
4. 使用编译后未经优化处理的配置
cp /usr/local/src/php-7.2.4/php.ini-production /usr/local/php7/etc/php.ini cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/ php7/etc/php-fpm.d/www.conf cp /usr/local/src/php-7.2.4/sapi/fpm/php-fpm.service /lib/systemd/system/php-fpm.service
5. 运行脚本
vi test.php
test.php 内容如下:
<?php
echo 123;
echo PHP_EOL;
运行: /usr/local/php7/bin/php test.php
结果如下:
123
5、 将php加入环境变量
echo -e '\nexport PATH=/usr/local/php7/bin:/usr/local/php7/sbin:$PATH\n' >> /etc/profile && source /etc/profile
然后运行 php test.php
结果就和上面一样了。
