# 编译
make

# 安装
make install

安装后的配置

# 执行完安装命令后php7就已经安装在到了/usr/local/php7目录下了。
/usr/local/php7/bin/php -v

# 添加环境变量
 vim /etc/profile
在文件的最后面添加下面两行代码
PATH=$PATH:/usr/local/php7/bin
export PATH
# 更新环境变量
source /etc/profile

# 查看环境变量
echo $PATH

# 查看php版本
php -v

配置PHP-FPM

cp php.ini-production /etc/php.ini
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
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

# 启动php-fpm
/etc/init.d/php-fpm start
或者
service php-fpm start

# 如果报错
Starting php-fpm [12-May-2018 20:09:45] ERROR: [pool www] cannot get uid for user 'www'

# 说明没有该用户，直接执行
groupadd www
useradd -g www www

进程等状态查看

# php 启动状态
ps -ef|grep php
