如果有下面这个错误

------------------------------------------------------------------------------------------

Please reinstall the libcurl distribution -easy.h should be in/include/curl/

解决方法

yum install curl curl-devel

重新configure

---------------------------------------------------------------------------------------

复制php.ini 到安装目录

cp php.ini-production /usr/local/php/etc/php.ini

在php.ini里找到date.timezone这行，把值改成PRC，如date.timezone = PRC。

如果没有这一行直接加上就好。最后重启WEB服务器与PHP即可。

把php-fpm添加到服务

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

vi /usr/local/php/etc/php-fpm.conf

把pid的选项打开，然后填入路径，我的路径是/usr/local/php/etc/php-fpm.pid

chmod a+x /usr/local/php/sbin/php-fpm  给权限

vi /usr/lib/systemd/system/php-fpm.service

[Unit]

Description=php-fpm

After=network.target

[Service]

Type=forking

ExecStart=/usr/local/php/sbin/php-fpm

ExecReload=kill -USR2 `cat /usr/local/php/etc/php-fpm.pid`

ExecStop=kill -INT `cat /usr/local/php/etc/php-fpm.pid`

PrivateTmp=true

[Install]

WantedBy=multi-user.target

如果出现错误

Warning: Unit file of nginx.service changed on disk,'systemctl daemon-reload' recommended

直接systemctl daemon-reload

设置开机启动

systemctl enable php-fpm.service 或者 systemctl enable php-fpm

停止开机启动

systemctl disable php-fpm.service

启动nginx服务

systemctl start php-fpm.service

查看服务当前状态

systemctl status php-fpm.service

重新启动服务

systemctl restart php-fpm.service

查看所有已启动的服务

systemctl list-units --type=service

查看进程

ps -ef | grep php-fpm

查看进程数量

ps | grep -c php-fpm

查看每个FPM的内存占用：

ps -ylC php-fpm --sort:rss

查看一下当前fastcgi进程个数

ss -napo |grep "php-fpm" | wc -l
