make && make install

ll  /usr/local/php7/lib/php/extensions/no-debug-non-zts-20170718/

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

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-20170718/"

######设置PHP的opcache和mysql动态库
zend_extension=opcache.so
extension=mysqli.so
extension=pdo_mysql.so
extension=ldap.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

[global]
pid = /usr/local/php7/var/run/php-fpm.pid
error_log = /usr/local/php7/var/log/php-fpm.log
log_level = notice

[www]
listen = /var/run/php-fpm/php-fpm.sock        ### 或者   127.0.0.1:9000
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = nginx
listen.group = nginx
listen.mode = 0666
user = nginx
group = nginx
pm = dynamic
pm.max_children = 80
pm.start_servers = 40
pm.min_spare_servers = 40
pm.max_spare_servers = 80
request_terminate_timeout = 100

request_slowlog_timeout = 10s
slowlog = /var/log/php-fpm/$pool-slow.log

######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/profile

mkdir -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/session

chown -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 start

ps -aux | grep php    ##php-fpm进程数和进程用户nginx都是由    pm.start_servers和user的 值分别决定的
