supervisor安装和自启动的一些问题

1、网上说：pip install supervisor
出现问题：bash：pip：command not found
需要安装pip：sudo easy_install pip
出现问题：sudo: easy_install: command not found
需要执行：sudo apt-get install python-setuptools
然后就可以：pip install supervisor
2、在supervisor默认配置中，其启动的sock等都会放到tmp目录，而tmp目录会自动清理（比如重启主机）导致无法使用supervisorctl命令；
修改supervisor.conf文件，修改到/var/run/及/var/log/目录
file=/var/run/supervisor.sock
serverurl=unix:///var/run/supervisor.sock ;等等

*注意：修改supervisor.conf文件后，要执行supervisorctl reload，重新加载配置文件；
*注意：supervisor好像需要root安装；
3、错误：Supervisorctl error: unix:///var/run/supervisord.sock refused connection?
说明需要开启supervisord。
echo_supervisord_conf > /etc/supervisord.conf //如果已经修改了supervisor.conf，这句就不要执行了
sudo supervisord -c /etc/supervisord.conf
sudo supervisorctl status
4、supervisor自启动
其实自启动，也就是在主机开启的时候，执行了sudo supervisord -c /etc/supervisord.conf；
创建/usr/lib/systemd/system/supervisord.service文件；
写入：
# dservice for systemd (CentOS 7.0+)
# by ET-CS (https://github.com/ET-CS)
[Unit]
Description=Supervisor daemon

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl shutdown
ExecReload=/usr/bin/supervisorctl reload
KillMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

*注意：我的supervisord的目录是/usr/local/bin/supervisord,需要把上边目录修改；
将文件拷贝至：“/usr/lib/systemd/system/supervisord.service”
systemctl enable supervisord

clip_image001
验证一下是否为开机启动：systemctl is-enabled supervisord
clip_image002

Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting

解决方法：

find / -name supervisor.sock

unlink /name/supervisor.sock

unix:///var/run/supervisor.sock no such file

sudo touch /var/run/supervisor.sock
sudo chmod 777 /var/run/supervisor.sock
sudo service supervisor restart
