supervisor：要安裝的軟件的名稱。
supervisord：裝好supervisor軟件後，supervisord用於啓動supervisor服務。
supervisorctl：用於管理supervisor配置文件中program。
方法一、使用yum命令安裝（推薦）
$ sudo su - #切換爲root用戶
# yum install epel-release
# yum install -y supervisor
# systemctl enable supervisord # 開機自啓動
# systemctl start supervisord # 啓動supervisord服務# systemctl status supervisord # 查看supervisord服務狀態
# ps -ef|grep supervisord # 查看是否存在supervisord進程
方法二、使用pip手工安裝配置(不推薦)
準備工作
確認9001端口未被佔用，如果9001端口被佔用，請將後面提到的supervisord.conf文件中的9001替換爲可用端口號，如7001。
一、安裝supervisor
切換爲root用戶
$ sudo su -
爲python2.7安裝pip（supervisor只支持python2.7）
(1) 下載pip
# wget https://bootstrap.pypa.io/get-pip.py --no-check-certificate
(2) 安裝pip
# python2.7 get-pip.py
如果遇到psutil相關的報錯，參考https://www.cnblogs.com/chentq/p/4954135.html
安裝supervisor
# pip2 install supervisor
#可能遇到的問題及解決辦法：
#如果遇到NameError: name 'sys_platform' is not defined
#運行如下命令即可（但是也會報錯，不用理會）
#pip2 install --upgrade distribute,
#然後再卸載supervisor，
#pip2 uninstall supervisor，
#重裝supervisor,
#pip2 install supervisor。
#參考http://www.yuchaoshui.com/post/CentOS6-Python-installation
創建supervisor所需目錄
# mkdir /etc/supervisord.d/
創建supervisor配置文件
# echo_supervisord_conf > /etc/supervisord.conf
編輯supervisord.conf文件
# vim /etc/supervisord.conf
文件內容如下(直接展示完整的文件內容，建議直接複製粘貼，如果想知道詳細改動，可逐行對比)

保存退出：wq
啓動supervisor
# supervisord -c /etc/supervisord.conf
查看supervisor是否啓動成功
# ps -ef|grep supervisord
root 932 1 0 May10 ? 00:00:09 /bin/python2.7 /bin/supervisord -c /etc/supervisord.conf
root 7902 6814 0 10:29 pts/0 00:00:00 grep --color=auto supervisord
至此，安裝supervisor就結束了
二、將supervisor配置爲開機自啓動服務
編輯服務文件
# vim /usr/lib/systemd/system/supervisord.service
內容如下
[Unit]
Description=Supervisor daemon[Service]
Type=forking
PIDFile=/var/run/supervisord.pid
ExecStart=/bin/supervisord -c /etc/supervisord.conf
ExecStop=/bin/supervisorctl shutdown
ExecReload=/bin/supervisorctl reload
KillMode=process
Restart=on-failure
RestartSec=42s[Install]
WantedBy=multi-user.target
保存退出 Esc:x
啓動服務
# systemctl enable supervisord
查看是否啓動
# systemctl is-enabled supervisord
enabled
成功之後，就可以使用如下命令管理supervisor服務了
# systemctl stop supervisord
# systemctl start supervisord
# systemctl status supervisord
# systemctl reload supervisord
# systemctl restart supervisord
至此，安裝supervisor和配置爲supervisor服務的工作就完成了。
補充：
因爲我們的supervisor使用的是root安裝，所以，對於非root用戶，如果在執行
$ supervisord -c /etc/supervisord.conf
$ supervisorctl
命令時，會遇到訪問被拒（Permission denied）的問題。
在命令最前面加上sudo即可
2. 如果更改了/etc/supervisord.conf中的端口號，原來的簡寫命令
# supervisorctl
就需要在後面指定supervsor配置文件位置，或指定supervisor服務運行的端口號
# supervisorctl -c /etc/supervisord.conf
# supervisorctl -s http://localhost:7001
否則會報連接拒絕
# supervisorctl
http://localhost:9001 refused connection
