#添加执行权限
chmod +x /etc/init.d/supervisor
#添加service和开机自启动
cd /etc/init.d
update-rc.d supervisor defaults
#创建supervisor依赖的文件夹
mkdir -p /etc/supervisor/conf.d mkdir /var/log/supervisor
#添加/etc/supervisor/supervisord.conf配置文件

#启动supervisor服务
service supervisor start
PS:由于线上apt-get安装的supervisor默认版本都是3.0b2这个版本,而这个版本很多业务都出现过supervisorctl重启应用卡住的情况,实际上就是执行成功了,却没有返回导致卡住,所以发版的时候就会hang在那里。google了一圈基本都尝试过也没有好的办法,而升级版本是可以解决这个问题的。。
详见:
https://github.com/Supervisor/supervisor/issues/131
如果线上已经在用的supervisor的,可以直接用pip install -U supervisor -i http://pypi.douban.com/simple,然后把/etc/init.d/supervisor文件中的DAEMON=/usr/bin/supervisord替换成DAEMON=/usr/local/bin/supervisord,再重启supervisor服务就好了,不过这样的做法会影响线上supervisor纳管的所有应用不可用(大概10s),所以要先和业务沟通哦^_^
