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。

编译安装PHP 7.24
系统环境:Centos 7.4

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

开始编译

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

#! /bin/sh
### BEGIN INIT INFO

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
# 查看是否开机启动 2:no 3:no 4:no级别下为启动
chkconfig --list php-fpm
php-fpm         0:off   1:off   2:on    3:on    4:on    5:on    6:off

重启、启动、停止php-fpm命令

# 启动
service php-fpm start
# 关闭
service php-fpm stop
