php-fpm配置详解_php实例
php5.3自带php-fpm
/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。
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.

Use php-fpm connection pool to improve database access performance
Jul 07, 2023 am 09:24 AM
Overview of using php-fpm connection pool to improve database access performance: In web development, database access is one of the most frequent and time-consuming operations. The traditional method is to create a new database connection for each database operation and then close the connection after use. This method will cause frequent establishment and closing of database connections, increasing system overhead. In order to solve this problem, you can use php-fpm connection pool technology to improve database access performance. Principle of connection pool: Connection pool is a caching technology that combines a certain number of databases
Detailed explanation of php-fpm tuning method
Jul 08, 2023 pm 04:31 PM
PHP-FPM is a commonly used PHP process manager used to provide better PHP performance and stability. However, in a high-load environment, the default configuration of PHP-FPM may not meet the needs, so we need to tune it. This article will introduce the tuning method of PHP-FPM in detail and give some code examples. 1. Increase the number of processes. By default, PHP-FPM only starts a small number of processes to handle requests. In a high-load environment, we can improve the concurrency of PHP-FPM by increasing the number of processes
