1，下载源码
wget http://cn2.php.net/distributions/php-7.2.4.tar.gz
php-7.2.4.tar.gz
2，解压
tar zxvf php-7.2.1.tar.gz
3、安装编译php需要的依赖包:
yum install gcc autoconf gcc-c++
yum 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 readline readline-devel libxslt libxslt-devel
yum install -y systemd-devel
yum install -y openjpeg-devel
4，（php-fpm配置文件默认php-fpm用户及用户组，不配置将使用默认用户启动php-fpm）
添加php-fpm用户
创建群组
groupadd php-fpm
创建一个用户，不允许登陆和不创主目录
useradd -s /sbin/nologin -g php-fpm -M php-fpm
5，编译参数: （根据自己需要编译）
注意：
开发环境:
–enable-phpdbg\
–enable-dtrace
生产环境:
–disable-phpdbg\
–disable-dtrace\

--with-xsl \
--enable-fpm \
--with-fpm-user=php-fpm \
--with-fpm-group=php-fpm \
--with-fpm-systemd \
--disable-fileinfo
说明：
--prefix=/opt/php7.2.4 #配置安装目录
--with-config-file-path=/opt/php7.2.4/etc #配置文件目录
--enable-fpm \ #安装php-fpm
--with-fpm-user=php-fpm \ #php-fpm启动用户
--with-fpm-group=php-fpm \ #php-fpm启动用户组
6，执行编译 make && make install
7，配置
php-ini:
源码包里面有配置文件:
- php.ini-development 测试开发环境*
- php.ini-production 生产环境*
复制一份到指定的目录下（根据自己的情况选用，自己可以对比下这两个文件的差异）:
cp php.ini-production /opt/php7.2.4/etc/php.ini
php-fpm复制一份新的php-fpm配置文件:
cd /opt/php7.2.4/etc
cp php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
配置错误日志:
error_log = /log/php/php-fpm.log
配置pid文件:
pid = /opt/php7.2.4/var/run/php-fpm.pid
保存退出
cd /opt/php7.2.4/etc/php-fpm.d
cp www.conf.default www.conf
管理php-fpm配置:
cd /opt/php-7.2.4 #源码路径
cp ./sapi/fpm/php-fpm.service 到 /usr/lib/systemd/system/下
配置开机启动php-fpm:
systemctl enable php-fpm
启动php-fpm：
systemctl start php-fpm
查看状态：
systemctl status php-fpm
添加环境变量:
vim /etc/profile
在末尾追加:
export PATH=$PATH:'/usr/local/php/bin/'
保存退出。
source /etc/profile
测试:
php -v
看到下面这个就表示已经成功了。
[root@centos-7 etc]# php -v

8，可能遇到的错误
启动失败，查看systemctl status php-fpm.service报如下错误：

A,打开日志文件错误，创建日志目录，修改目录权限
mkdir /log/php/
chmod -R 755 /log
如果需要区分web和cli环境，可以将 /usr/local/php/etc/php.ini 复制一份，重命名为
php-cli.ini
cp /usr/local/php/etc/php.ini /usr/local/php/etc/php-cli.ini
需要调整配置，就在各自的配置文件中进行调整即可。
