Ubuntu 下 Supervisor 安装与配置

1，安装

$sudo apt-get install supervisor

2，配置

/etc/supervisor/supervisord.conf 一般不用动

3，创建子进程配置文件,修改权限

$ touch /etc/supervisor/conf.d/laravel-worker.conf

$ chmod -R 777 /etc/supervisor/conf.d/

一般配置：

[program:laravel-worker]

process_name=%(program_name)s

command=php /项目文件地址/artisan queue:work --sleep=3 --timeout=50 （这个配置需要替换，此处是我laravel 开启队列监听的指令）

autostart=true (自动开启)

autorestart=true (自动重启)

numprocs=1（同时开启进程数，进程数不同，上面的 process_name 配置也不同 为1 时是 %(program_name)s ）

redirect_stderr=true

4，杀掉原有进程

$ps -ef | grep supervisor

$kill 9 (对应 pid 号)        |  例如 $kill 9 7381

root        6689        1  0 10:30 ?          00:00:00 /usr/bin/python /usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf
bitnami   7381  5967  0 11:06 pts/0    00:00:00 grep --color=auto supervisor

5，启动

$sudo supervisord –c /etc/supervisor/supervisord.conf (配置文件)

报错1：

bitnami@ip-172-31-33-147:/etc/supervisor/conf.d$supervisord -c /etc/supervisor/supervisord.conf

Traceback(most recent call last):

IOError: [Errno 13]Permission denied: '/var/log/supervisor/supervisord.log'

解决方法: 更改/var/log/supervisor/supervisord.log 权限为 777

报错2：

bitnami@ip-172-31-33-147:/etc/supervisor$

supervisord -c /etc/supervisor/supervisord.conf

Error: Cannot open anHTTP server: socket.error reported errno.EACCES (13)

解决方法：更改 /var/run 文件夹的权限，这里注意是只更改这个文件夹的权限不要连里面的文件也更改，不要加–R 参数，不然会更改 ssh 秘钥权限，导致你上不去服务器，只能重启服务器，这里执行

$sudo chmod 777 /run 

（/var/run 是 /run 的软链接）

6，重新加载配置文件，启动子进程守护进程

$sudo supervisorctl reread

$sudo supervisorctl update

$sudo supervisorctl start laravel-worker:*
