使用supervisor管理php-fpm时遇到的问题
supervisor的配置如下:
1 [program:php7-fpm] 2 command=/usr/local/php-7.1.3/sbin/php-fpm -y /usr/local/php-7.1.3/etc/php-fpm.conf -c /usr/local/php-7.1.3/lib/php.ini 3 directory=/root 4 autostart=true 5 autorestart=true 6 startretries=3 7 stderr_logfile=/var/log/supervisor/php7-fpm.err.log 8 stdout_logfile=/var/log/supervisor/php7-fpm.out.log 9 user=root
在启动的时候虽然php-fpm有启动,但supervisor总是报错,提示启动失败,错误日志如下:
2017-03-25 14:12:41,732 INFO spawned: 'php7-fpm' with pid 29351 2017-03-25 14:12:41,774 INFO exited: php7-fpm (exit status 0; not expected) 2017-03-25 14:12:42,776 INFO spawned: 'php7-fpm' with pid 29359 2017-03-25 14:12:42,814 INFO exited: php7-fpm (exit status 70; not expected) 2017-03-25 14:12:44,818 INFO spawned: 'php7-fpm' with pid 29361 2017-03-25 14:12:44,840 INFO exited: php7-fpm (exit status 70; not expected) 2017-03-25 14:12:47,845 INFO spawned: 'php7-fpm' with pid 29363 2017-03-25 14:12:47,867 INFO exited: php7-fpm (exit status 70; not expected) 2017-03-25 14:12:48,869 INFO gave up: php7-fpm entered FATAL state, too many start retries too quickly
翻看supervisor的文档时发现了如下描述:
Controlled programs should themselves not be daemons, as supervisord assumes it is responsible for daemonizing its subprocesses (see Nondaemonizing of Subprocesses).
于是将php-fpm.conf中的配置修改如下:
; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging. ; Default Value: yes daemonize = no
再次使用supervisor启动php-fpm成功:
supervisorctl start php7-fpm
php7-fpm: started
