下面的是参考https://typecodes.com/ 过了一遍，和前面的nginx 连接 测试没有问题。与mysql连接的时候，注意参数 --with-mysql-sock=/var/run/mysql/mysql.sock，需要和mysql里面设置的是一样。yum -y install libxml2 libxml2-devel openssl openssl-devel curl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel

直接使用编译后未经优化处理的配置cp php.ini-production /usr/local/php7/etc/php.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-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

修改配置文件
vim /usr/local/php7/etc/php.ini######避免PHP信息暴露在http头中
expose_php = Off
######避免暴露php调用mysql的错误信息
display_errors = Off######在关闭display_errors后开启PHP错误日志（路径在php-fpm.conf中配置）
log_errors = On######设置PHP的扩展库路径
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/"######设置PHP的opcache和mysql动态库
zend_extension=opcache.so
extension=mysqli.so
extension=pdo_mysql.so######设置PHP的时区
date.timezone = PRC######开启opcache
[opcache]
opcache.enable=1
######设置PHP脚本允许访问的目录（需要根据实际情况配置）
open_basedir = /etc/nginx/html;

vim /usr/local/php7/etc/php-fpm.conf######设置错误日志的路径
error_log = /var/log/php-fpm/error.log
######引入www.conf文件中的配置
include=/usr/local/php7/etc/php-fpm.d/*.conf

vim /usr/local/php7/etc/php-fpm.d/######设置用户和用户组
user = nginx
group = nginx
######根据nginx.conf中的配置fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;设置PHP监听
; listen = 127.0.0.1:9000  #####不建议使用（看自己设置情况）
listen = /var/run/php-fpm/php-fpm.sock
######开启慢日志
slowlog = /var/log/php-fpm/$pool-slow.log
request_slowlog_timeout = 10s
######设置php的session目录（所属用户和用户组都是nginx）
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session

echo -e '\nexport PATH=/usr/local/php7/bin:/usr/local/php7/sbin:$PATH\n' >> /etc/profile && source /etc/profilemkdir -p /var/log/php-fpm/ && mkdir -p /var/run/php-fpm && cd /var/run/ && chown -R nginx:nginx php-fpm
mkdir -p /var/lib/php/sessionchown -R nginx:nginx /var/lib/php
chmod +x /etc/init.d/php-fpm
chkconfig --add php-fpm
chkconfig php-fpm on
php-fpm -t
service php-fpm startps -aux | grep php    ##php-fpm进程数和进程用户nginx都是由www.conf中pm.start_servers和user的值分别决定的
