一、下载源码
wget http://cn.php.net/distributions/php-7.2.4.tar.gz
二、解压源码
tar -zxvf php-7.2.4.tar.gz
三、编译
1、配置
./configure --prefix=/usr/local/php \ --with-curl \ --with-freetype-dir \ --with-gd \ --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-mbregex \ --enable-mbstring \ --enable-opcache \ --enable-pcntl \ --enable-shmop \ --enable-soap \ --enable-sockets \ --enable-sysvsem \ --enable-xml \ --enable-zip
配置过程错误解决方法：
1、libxml2 configure: error: xml2-config not found. Please check your libxml2 installation. apt-get install libxml2-dev 2、configure: error: Cannot find OpenSSL's libraries apt-get install pkg-config libssl-dev openssl 3、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 apt-get install libcurl4-gnutls-dev curl 4、configure: error: png.h not found. apt-get install libpng-dev 5、configure: error: freetype-config not found. apt-get install libfreetype6-dev 6、configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution apt-get install libxslt1-dev
也可以在配置前直接执行：
apt-get install libxml2-dev pkg-config libssl-dev openssl libcurl4-gnutls-dev curl libpng-dev libfreetype6-dev libxslt1-dev
2、编译安装
make & make install
四、配置PHP
1、
vim ~/.bash_aliases
写入信息
alias php='/usr/local/php/bin/php' alias phpize='/usr/local/php/bin/phpize' alias php-fpm='/usr/local/php/sbin/php-fpm'
使设置生效
source ~/.bash_aliases
2、
cp php.ini-development /usr/local/php/lib/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 cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm chmod +x /etc/init.d/php-fpm update-rc.d php-fpm defaults
3、修改www.conf配置
vim /usr/local/php/etc/php-fpm.d/www.conf
user = www-data group = www-data listen = /run/php/php7.0-fpm.sock listen.owner = www-data listen.group = www-data pm.max_requests = 5000
注：需要创建/run/php目录
mkdir /run/php
4、修改php.ini配置
vim /usr/local/php/lib/php.ini
post_max_size = 100M upload_max_filesize = 80M date.timezone = PRC
五、启动php-fpm
service php-fpm start
