Supervisor集中化管理web工具cesi安装配置

supervisor不支持跨机器的进程监控,一个supervisord只能监控本机上的程序,大大限制了supervisor的使用.
不过由于supervisor本身支持xml-rpc,因此也有一些基于supervisor二次开发的多机器进程管理工具.比如:
Django-Dashvisor
Web-based dashboard written in Python. Requires Django 1.3 or 1.4.
Nodervisor
Web-based dashboard written in Node.js.
Supervisord-Monitor
Web-based dashboard written in PHP.
SupervisorUI
Another Web-based dashboard written in PHP.
cesi
cesi is a web interface provides manage supervizors from same interface.
本文着重介绍cesi.

具体安装步骤:

[root@test yum.repos.d]# yum install -y sqlite python python-flask
[root@test home]# git clone https://github.com/gamegos/cesi //如果没有git命令,可yum install -y git安装
[root@test home]# cd cesi/
[root@test cesi]# ll

[root@test cesi]# sqlite3 ./userinfo.db < userinfo.sql
上述命令执行完会多一个userinfo.db文件.

查看表:
[root@test cesi]# sqlite3 userinfo.db

Enter ".help" for instructions
Enter SQL statements terminated with a ";"

sqlite> .quit

配置cesi.conf:
[root@test cesi]# cp /home/cesi/cesi.conf /etc/ //启动的默认配置文件为/etc/cesi.conf,这一点一定要注意
[root@test cesi]# cat /etc/cesi.conf
[node:test01]
username = test01
password = test01
host = 1.2.3.4
port = 9001 //主机1.2.3.4supervisor的web端口

[node:test01]
username = test02
password = test02
host = 4.5.6.7
port = 9001

[environment:cesi_test]
members = test01,test02

[cesi]
database = /home/cesi/userinfo.db
activity_log = /var/log/cesi.log
host = 0.0.0.0

用supervisor运行cesi,配置文件如下:
[root@test supervisord.d]# cat /etc/supervisord.d/cesi.ini
[program:cesi]
directory = /home/cesi/cesi/
command = python web.py
autostart = true
startsecs = 5
autorestart = true
startretries = 3
user = root
redirect_stderr = true
stdout_logfile = /var/log/cesi1.log

启动cesi:
[root@test supervisord.d]# supervisorctl -c /etc/supervisord.conf reload //重新载入配置文件
Restarted supervisord
[root@test supervisord.d]# supervisorctl -c /etc/supervisord.conf status
cesi BACKOFF Exited too quickly (process log may have details)
tomcat RUNNING pid 22590, uptime 0:00:05
[root@test log]# supervisorctl start cesi //启动cesi服务
[root@test log]# supervisorctl status
cesi RUNNING pid 22732, uptime 0:00:30
tomcat RUNNING pid 22590, uptime 0:07:39
默认账号密码:admin,admin,记得一定要修改(web页面右上角修改密码).也可以直接在上面的步骤中修改/home/cesi/userinfo.sql这个sql语句,直接先将密码改掉.cesi默认端口是5000.
web界面如下:

可在web页面直接重启受管理机器的相关服务.
