1.下载PHP源码文件

通过wget下载源码

PHP版本以及下载地址可以去 http://php.net/downloads.php 选择，这里我们以7.1.19来演示

1、cd /usr/local/src/

2、wget -O php-7.1.19.tar.gz http://cn2.php.net/get/php-7.1.19.tar.gz/from/this/mirror

2.安装PHP

1、先将文件解压
tar -zxvf php-7.1.19.tar.gz

2、解压之后得到一个文件夹，进入这个文件夹
cd php-7.1.19

3、安装之前先安装一些支持库
yum -y install gcc
yum -y install openssl openssl-devel
yum -y install curl-devel
yum -y install libjpeg-devel
yum -y install libpng-devel
yum -y install freetype-devel
yum -y install libxslt-devel
yum -y install libxml2 libxml2-devel
yum -y install epel-release
yum -y install libmcrypt-devel

4、配置PHP
这块特别消耗时间，因此你可以干的别的事
./configure —prefix=/usr/local/php \
—with-config-file-path=/usr/local/php/etc/ \
—with-curl \
—with-freetype-dir \
—with-gd \
—with-jpeg-dir \
—with-gettext \
—with-iconv-dir \
—with-kerberos \
—with-libdir=lib64 \
—with-libxml-dir \
—with-mysqli \
—with-openssl \
—with-pcre-regex \
—with-pdo-mysql \
—with-pdo-sqlite \
—with-pear \
—with-png-dir \
—with-xmlrpc \
—with-xsl \
—with-zlib \
—enable-fpm \
—enable-bcmath \
—enable-libxml \
—enable-inline-optimization \
—enable-gd-native-ttf \
—enable-mbregex \
—enable-mbstring \
—enable-opcache \
—enable-pcntl \
—enable-shmop \
—enable-soap \
—enable-sockets \
—enable-sysvsem \
—enable-xml \
—enable-zip

5、编译安装
make
make install

6、拷贝配置文件到PHP目录

cp php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

3.开启php-fpm开机自启动

1、vi /etc/systemd/system/php-fpm.service

2、写入如下代码
[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target

[Service]
Type=simple
PIDFile=/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm —nodaemonize —fpm-config /usr/local/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
ExecStop=/bin/kill -SIGINT $MAINPID

[Install]
WantedBy=multi-user.target

3、启动php-fpm
systemctl start php-fpm.service
4、添加到开机启动
systemctl enable php-fpm.service

4.配置环境变量

1、vi /etc/profile
文件最底部写入
PATH=$PATH:/usr/local/php/bin:
export PATH

2、wq退出

3、执行命令使配置生效
php -v

安装完毕
