How to restart php-fpm inside a docker container?
提问by Eugene Sue
I'm using docker and my container is build over php:5.6-fpm image from php official repo. Is it somehow possible to restart/reload php-fpm from inside a container?

php-fpmis a process manager which supports the USER2 signal, which is used to reload the config file.
php-fpm是一个支持 USER2 信号的进程管理器，用于重新加载配置文件。
From inside the container:

kill -USR2 1
Outside:
外部：
docker exec -it <mycontainer> kill -USR2 1

This works for me:
这对我有用：
If the command fpm restart fails run this inside the Docker container -> www#:
如果命令 fpm restart 失败，请在 Docker 容器中运行此命令 -> www#：
root@...:/var/www# **ps -ef|grep fpm**
www-data 160 1 0 10:02 ? 00:00:00 php-fpm: pool www
www-data 161 1 0 10:02 ? 00:00:00 php-fpm: pool www
root 1111 170 0 10:04 pts/0 00:00:00 grep --color=auto fpm
root@...:/var/www# **kill -USR2 170**
root@...:/home/user/Docker# **docker-compose stop**
Stopping docker_nginx_1 ... done
Stopping docker_oracle_1 ... done
root@...:/home/user/Docker# **docker-compose up -d**
Starting docker_oracle_1 ... done
Starting docker_nginx_1 ... done
root@...:/home/user/Docker# **docker-compose exec oracle bash**
root@...:/var/www# **/etc/init.d/php7.2-fpm restart**

You don't have to go inside the container
你不必进入容器内
on your host
ps -ef|grep fpm // find master pid
kill -USR2 <master_pid>
在你的主机上
ps -ef|grep fpm // find master pid
kill -USR2 <master_pid>
