7.2、复制php.ini
产品
cp php.ini-production /usr/local/php/lib/php.ini
开发
cp php.ini-development /usr/local/php/lib/php.ini
gd库
cd /ext/gd
/usr/local/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-png-dir --with-freetype-dir --with-jpeg-dir --with-zlib-dir --with-gd
8、配置php-fpm.conf
pid=/usr/local/php/var/run/php-fpm.pid
user = www
group = www
pm = static
pm.max_children = 64

==================================
mynote:以上修改内容在php-fpm.conf文件中找到对应的地方一一修改

/usr/local/php/sbin/php-fpm

确认
ps -elf | grep php | wc -l
根据刚才的php-fpm.conf应该输出是66

9.2、暂停php-fpm
kill -INT cat /usr/local/php/var/run/php-fpm.pid

9.3、php-fpm 重启:
kill -USR2 cat /usr/local/php/var/run/php-fpm.pid
