cp -f /tools/php-5.3.6/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
php-fpm的启动：
##vim /usr/local/webserver/php/etc/php-fpm.conf
php-fpm.pid 目录必须是：/usr/local/webserver/php/var/run/php-fpm.pid
 
chmod 755 /etc/init.d/php-fpm
/etc/init.d/php-fpm start
/sbin/chkconfig --add php-fpm (添加到开机服务列表)
/sbin/chkconfig php-fpm on
 
php-fpm的启动、停止和重启：
/etc/init.d/php-fpm start
/etc/init.d/php-fpm stop
 
/etc/init.d/php-fpm reload
 
启动效果如下：
 
Hai_ISD_7_9_Cent56_64:/usr/local/webserver/php/etc#service php-fpm start
Starting php-fpm  done
Hai_ISD_7_9_Cent56_64:/usr/local/webserver/php/etc#service php-fpm stop
Gracefully shutting down php-fpm . done
Hai_ISD_7_9_Cent56_64:/usr/local/webserver/php/etc#service php-fpm start
Starting php-fpm  done
Hai_ISD_7_9_Cent56_64:/usr/local/webserver/php/etc#service php-fpm reload
Reload service php-fpm  done

/usr/local/php/etc/php-fpm.conf
 
pid = run/php-fpm.pid
pid设置，默认在安装目录中的var/run/php-fpm.pid，建议开启
 
error_log = log/php-fpm.log
错误日志，默认在安装目录中的var/log/php-fpm.log
 
log_level = notice
错误级别. 可用级别为: alert（必须立即处理）, error（错误情况）, warning（警告情况）, notice（一般重要信息）, debug（调试信息）. 默认: notice.
 
emergency_restart_threshold = 60
emergency_restart_interval = 60s
表示在emergency_restart_interval所设值内出现SIGSEGV或者SIGBUS错误的php-cgi进程数如果超过emergency_restart_threshold个，php-fpm就会优雅重启。这两个选项一般保持默认值。
 
process_control_timeout = 0
设置子进程接受主进程复用信号的超时时间. 可用单位: s(秒), m(分), h(小时), 或者 d(天) 默认单位: s(秒). 默认值: 0.
 
daemonize = yes
后台执行fpm,默认值为yes，如果为了调试可以改为no。
 
在FPM中，可以使用不同的设置来运行多个进程池。 这些设置可以针对每个进程池单独设置。
 
listen = 127.0.0.1:9000
fpm监听端口，即nginx中php处理的地址，一般默认值即可。
可用格式为: ‘ip:port’, ‘port’, ‘/path/to/unix/socket’. 每个进程池都需要设置.
 
listen.backlog = -1
backlog数，-1表示无限制，由操作系统决定，此行注释掉就行。backlog含义参考：
 
listen.allowed_clients = 127.0.0.1
允许访问FastCGI进程的IP，设置any为不限制IP，如果要设置其他主机的nginx也能访问这台FPM进程，listen处要设置成本地可被访问的IP。默认值是any。
每个地址是用逗号分隔. 如果没有设置或者为空，则允许任何服务器请求连接
 
listen.owner = www
listen.group = www
listen.mode = 0666
unix socket设置选项，如果使用tcp方式访问，这里注释即可。
 
user = www
group = www
启动进程的帐户和组
 
pm = dynamic
如何控制子进程，选项有static和dynamic。
如果选择static，则由pm.max_children指定固定的子进程数。
如果选择dynamic，则由下开参数决定：
pm.max_children，子进程最大数
pm.start_servers，启动时的进程数
pm.min_spare_servers，保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.max_spare_servers，保证空闲进程数最大值，如果空闲进程大于此值，此进行清理
对于专用服务器，pm可以设置为static。
 
pm.max_requests = 1000
设置每个子进程重生之前服务的请求数. 对于可能存在内存泄漏的第三方模块来说是非常有用的. 如果设置为 ’0′ 则一直接受请求. 等同于 PHP_FCGI_MAX_REQUESTS 环境变量. 默认值: 0.
 
pm.status_path = /status
FPM状态页面的网址. 如果没有设置, 则无法访问状态页面. 默认值: none.
 
ping.path = /ping
FPM监控页面的ping网址. 如果没有设置, 则无法访问ping页面. 该页面用于外部检测FPM是否存活并且可以响应请求. 请注意必须以斜线开头 (/)。
 
ping.response = pong
用于定义ping请求的返回相应. 返回为 HTTP 200 的 text/plain 格式文本. 默认值: pong.
 
request_terminate_timeout = 0
设置单个请求的超时中止时间. 该选项可能会对php.ini设置中的’max_execution_time’因为某些特殊原因没有中止运行的脚本有用. 设置为 ’0′ 表示 ‘Off’.
当经常出现502错误时可以尝试更改此选项。
 
request_slowlog_timeout = 10s
当一个请求该设置的超时时间后，就会将对应的PHP调用堆栈信息完整写入到慢日志中. 设置为 ’0′ 表示 ‘Off’
 
slowlog = log/$pool.log.slow
慢请求的记录日志,配合request_slowlog_timeout使用
 
rlimit_files = 1024
设置文件打开描述符的rlimit限制. 默认值: 系统定义值
系统默认可打开句柄是1024，可使用 ulimit -n查看，ulimit -n 2048修改。
 
rlimit_core = 0
设置核心rlimit最大限制值. 可用值: ‘unlimited’ 、0或者正整数. 默认值: 系统定义值.
 
chroot =
启动时的Chroot目录. 所定义的目录需要是绝对路径. 如果没有设置, 则chroot不被使用.
 
chdir =
设置启动目录，启动时会自动Chdir到该目录. 所定义的目录需要是绝对路径. 默认值: 当前目录，或者/目录（chroot时）
 
catch_workers_output = yes
重定向运行过程中的stdout和stderr到主要的错误日志文件中. 如果没有设置, stdout 和 stderr 将会根据FastCGI的规则被重定向到 /dev/null . 默认值: 空.
