Supervisor部署

Supervisor是用Python开发的一个client/server服务，是Linux/Unix系统下的一个进程管理工具，不支持Windows系统。很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程，当一个进程意外被Kill，会自动将它重新拉起，不需要开发者自己编写shell进行进程管理来维护自己的服务。

安装Supervisor

采用Ubuntu系统下的安装方式进行演示：

apt-get -y install supervisor

创建配置文件

vim /etc/supervisor/conf.d/easyswoole.conf

文件内容如下：

# 设置应用名称为easyswoole
[program:easyswoole]
# 设置运行目录
directory=/data/wwwroot/EasySwoole3.4.x
# 项目的启动命令
command=php easyswoole server start
# 设置用户来运行该进程
user=www-data
# 是否随着supervisor启动时 自动启动该应用
autostart=true
# 进程退出 是否自动重启进程
autorestart=true
# 进程启动多少秒之后被认为是启动成功 默认1s
startsecs=1
# 失败最大尝试次数 默认3
startretries=3
# stderr
stderr_logfile=/data/wwwlog/easyswoole-stderr.log
# stdout
stdout_logfile=/data/wwwlog/easyswoole-stdout.log

启动Supervisor
service supervisor start

Supervisorctl

启动EasySwoole应用

supervisorctl start easyswoole

停止EasySwoole应用
