cd /usr/lib/systemd/system
touch php-fpm.service
输入以下内容到新建的文件
[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target
[Service]
Type=simple
PIDFile=/usr/local/php/var/run/php-fpm.pid
ExecStart=/usr/local/bin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
ExecStop=/bin/kill -SIGINT $MAINPID
[Install]
WantedBy=multi-user.target
#启动
systemctl start php-fpm.service
#查看状态
systemctl status php-fpm.service
#开机启动
systemctl enable php-fpm.service
systemctl daemon-reload
[Unit]部分主要是对这个服务的说明，内容包括Description和After，Description用于描述服务，After用于描述服务类别
[Service]部分是服务的关键，是服务的一些具体运行参数的设置，这里Type=forking是后台运行的形式，PIDFile为存放PID的文件路径，ExecStart为服务的具体运行命令，ExecReload为重启命令，ExecStop为停止命令，PrivateTmp=True表示给服务分配独立的临时空间，
注意：[Service]部分的启动、重启、停止命令全部要求使用绝对路径，使用相对路径则会报错！
[Install]部分是服务安装的相关设置，可设置为多用户的
php-fpm的配置文件
php-fpm.conf 的listen要跟nginx中的代理端口要一样的哦 也可以都改成sock地址
nginx
location ~ [^/]\.php(/|$)
{
try_files $uri =404;
fastcgi_pass unix:/tmp/php-cgi.sock;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
z@z-PC:/usr/local/php/etc$ cat /usr/local/php/etc/php-fpm.conf
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice
[www]
listen = /tmp/php-cgi.sock
#listen = 127.0.0.1:9000
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 60
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 60
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log
php-fpm master进程控制
INT, TERM 立刻终止
QUIT 平滑终止
USR1 重新打开日志文件
USR2 平滑重载所有worker进程并重新载入配置和二进制模块

重启php-fpm方式
#相当于重启master
kill -USR2 8848
#同样效果
kill -USR2`cat /usr/local/php/var/run/php-fpm.pid`
#关闭
kill -INT `cat /usr/local/php/var/run/php-fpm.pid`
