php-fpm配置的一个坑

调了一个下午,发现 php-fpm 有个怪坑

我在 docker 下,基于 php:7.0-fpm 镜像,构建了一个容器

并且 ADD ./app.pool.conf /usr/local/etc/php-fpm.d/ ,放了个 pool 进去

具体内容为

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
user = www-data
group = www-data
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 0.0.0.0:9000
; Choose how the process manager will control the number of child processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on the
; following directives. With this process management, there will be
; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 20
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 2
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3

; Make specific Docker environment variables available to PHP
env[DB_1_ENV_MYSQL_DATABASE] = $DB_1_ENV_MYSQL_DATABASE
env[DB_1_ENV_MYSQL_USER] = $DB_1_ENV_MYSQL_USER
env[DB_1_ENV_MYSQL_PASSWORD] = $DB_1_ENV_MYSQL_PASSWORD
catch_workers_output = yes

然而…

php-fpm 一启动就报错

研究了好几个钟头无果

瞎弄的时候把 app.pool.conf 重命名成了 aaa.pool.conf

神奇的发现, php-fpm 正常了

然后测试了几个文件名,发现只要是 app 打头,都会造成 php-fpm 抽筋…目测是撞上了什么奇怪的规则

然而我 Google 搜了好久都没发现有人报告这个问题…_(:3」∠)_

嘛,自己记录一下吧.
