Worker starting control

Supervisor

Supervisor 是Linux的进程监视器。
它会自动启动您的控制台进程。
安装在Ubuntu上,你需要运行命令:

sudo apt-get install supervisor

Supervisor 配置文件通常可用 /etc/supervisor/conf.d。 你可以创建任意数量的配置文件。

配置示例:

[program:yii-queue-worker]
process_name=%(program_name)s_%(process_num)02d
command=/usr/bin/php /var/www/my_project/yii queue/listen --verbose=1 --color=0
autostart=true
autorestart=true
user=www-data
numprocs=4
redirect_stderr=true
stdout_logfile=/var/www/my_project/log/yii-queue-worker.log

在这种情况下,Supervisor 会启动4个 queue/listen worker。输出将写入相应日志文件。

有关 Supervisor 配置和使用的更多信息,请参阅文档

以守护进程模式启动的Worker使用 queue/listen 命令支持 FileDbRedisRabbitMQBeanstalkGearman 驱动。 有关其他参数,请参阅驱动程序指南。

Systemd

Systemd is an init system used in Linux to bootstrap the user space. To configure workers startup using systemd, create a config file named yii-queue@.service in /etc/systemd/system with the following contents:

[Unit]
Description=Yii Queue Worker %I
After=network.target
# the following two lines only apply if your queue backend is mysql
# replace this with the service that powers your backend
After=mysql.service
Requires=mysql.service

[Service]
User=www-data
Group=www-data
ExecStart=/usr/bin/php /var/www/my_project/yii queue/listen --verbose
Restart=on-failure

[Install]
WantedBy=multi-user.target

You need to reload systemd in order for it to re-read configuration:

systemctl daemon-reload

Set of commands to control workers:

# To start two workers
systemctl start yii-queue@1 yii-queue@2

# To get status of running workers
systemctl status "yii-queue@*"

# To stop the worker
systemctl stop yii-queue@2

# To stop all running workers
systemctl stop "yii-queue@*"

# To start two workers at system boot
systemctl enable yii-queue@1 yii-queue@2

To learn all features of systemd, check its documentation.

Cron

您可以用cron开始worker。需要使用 queue/run 命令。只要队列包含作业,它就能进行执行。

配置示例:

* * * * * /usr/bin/php /var/www/my_project/yii queue/run

在这种情况下,cron将每分钟启动一次命令。

queue/run 命令支持 FileDbRedisBeanstalkGearman驱动。有关其他选项,请参阅驱动程序指南。
