1、下载php后解压

tar xvzf php-7.4.3.tar.gz
cd php-7.4.3

2、安装依赖

yum -y install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel oniguruma oniguruma-devel

3、编译  默认指定安装目录  /usr/local/php7  默认php.ini目录  /usr/local/php7/etc/php.in  与原有php5.x不冲突

./configure \
--prefix=/usr/local/php7 \
--with-config-file-path=/usr/local/php7/etc \
--enable-fpm \

--enable-wddx \
--with-libxml-dir \
--with-xsl \
--enable-zip \
--enable-mysqlnd-compression-support \
--with-pear \
--enable-opcache

make -j && make install

4、初始化配置文件

cp php.ini-production /usr/local/php7/etc/php.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm
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

#php-fpm 端口可在 www.conf 里修改

chmod +x /etc/init.d/php7-fpm

/etc/init.d/php7-fpm start

# php7加入环境变量
ln -s /usr/local/php7/bin/php /usr/local/bin/php7
