配置

cd /etc/

echo_supervisord_conf > supervisord.conf
vim /etc/supervisord.conf
#加入以下配置信息
[include]
files = /etc/supervisord.d/*.conf

开机启动服务文件

       echo -n $"Starting $prog: "
       ###注意下面这一行一定得有-c /etc/supervisord.conf   不然修改了配置文件根本不生效！
       daemon $prog_bin -c /etc/supervisord.conf --pidfile $PIDFILE

chmod +x /etc/init.d/supervisord
chkconfig --add supervisord
chkconfig supervisord on
service supervisord start

开启web查看

# 如果想通过web查看管理的进程，加入以下代码，监听9001，用户user，密码123
[inet_http_server] 
port=9001
username=user      
password=123

创建一个任务

#在重启之前随便创建一个挂在后台的命令
vim /etc/supervisord.d/tail.conf

[program:task1]                                                                            
command=tail -f  /etc/supervisord.conf   ;常驻后台的命令
autostart=true                           ;是否随supervisor启动
autorestart=true                         ;是否在挂了之后重启，意外关闭后会重启，比如kill掉！
startretries=3                           ;启动尝试次数
stderr_logfile=/tmp/task1.err.log        ;标准输出的位置
stdout_logfile=/tmp/task1.out.log        ;标准错误输出的位置

查看服务是否启动

##查看一下是否监听
lsof -i:9001
COMMAND    PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
superviso 7782 root    4u  IPv4 74522612      0t0  TCP *:etlservicemgr (LISTEN)

web方式查看

http://ip:9001
