网络资料显示PHP7性能是PHP5的三倍（wordpress 而言），而且代码向下兼容，春风也把PHP5.6更换成了PHP7.2，性能提升明显，而且感觉更节省内存。

安装依赖
yum -y install gd-devel zlib-devel libjpeg-devel libpng-devel libiconv-devel freetype-devel libxml2 libxml2-devel openssl openssl-devel curl-devel libxslt-devel libmcrypt-devel mhash
下载PHP7.24
wget http://cn2.php.net/distributions/php-7.2.4.tar.gz
解压后进入PHP7.24目录
#解压
tar -xzvf php-7.2.4.tar.gz
#进入目录
cd php-7.2.4
新建用户 我这里使用Tengine的用户
#新建www用户组
groupadd www
#新建Tengine用户
useradd -g www tengine -s /sbin/nologin

安装
make && make install
更改PHP安装目录所属用户 复制配置文件
#新建配置文件目录
mkdir -p data/apps/conf/php/etc/php-fpm.d
#复制配置文件
cp -rf /data/apps/php/etc/* /data/apps/conf/php/etc
cp /root/php-7.2.4/php.ini* /data/apps/php/etc/
#到安装目录
cd /data/apps/conf/php/etc
#把php.ini-production复制为php.ini
cp php.ini-production php.ini
#把php-fpm.conf.default复制为php-fpm.conf
cp php-fpm.conf.default php-fpm.conf
#把php-fpm.d/www.conf.default复制为php-fpm.d/www.conf
cp php-fpm.d/www.conf.default php-fpm.d/www.conf
#更改PHP安装目录所属用户
chown -R tengine:www /data/apps/php /data/apps/conf/php
配置php.ini
# 字符集UTF-8
default_charset = "UTF-8"
# 设置PHP的扩展库路径，默认被注释了。
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/"
#添加opcache扩展
zend_extension=opcache.so
# 设置PHP的时区
date.timezone = PRC
# 开启opcache，默认是0
[opcache]
opcache.enable=1
配置php-fpm.d目录下www.conf
; 设置用户和用户组
user = tengine
group = www
; 下面是默认值，如果PHP Nginx在一台服务器不建议使用 我这里注释掉
; listen = 127.0.0.1:9000
; sock目录改为/dev/shm物理硬件内存 读写速度比硬盘快N倍
listen = /dev/shm/php-fpm.sock
保存配置检验配置是否正确
/data/apps/php/sbin/php-fpm -t
添加环境变量
#编辑/etc/profile
vim /etc/profile
#在尾部加入
export PATH=/data/apps/php/bin:/data/apps/php/sbin
启动
/data/apps/php/sbin/php-fpm
让tengine或Nginx 支持PHP
编辑nginx.conf更改为以下内容。
#PHP模块
location ~ \.php$ {
fastcgi_pass unix:/dev/shm/php-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
创建开机启动脚本
vim /etc/init.d/php-fpm
写入以下内容

把php-fpm加入服务 设置为启动
# 给php-fpm可执行权限
chmod +x /etc/init.d/php-fpm
# php-fpm加入服务
chkconfig --add php-fpm
# php-fpm 设置为开机启动
chkconfig php-fpm on

重启、启动、停止php-fpm命令
# 启动
service php-fpm start
# 关闭
service php-fpm stop
# 重启
