supervisor 配置篇

1，配置管理进程

进程管理配置参数，不建议全都写在supervisord.conf文件中，应该每个进程写一个配置文件放在include指定的目录下包含进supervisord.conf文件中。 
1> 创建/etc/supervisor/目录，用于存放进程管理的配置文件 
2> 修改/etc/supervisord.conf中的include参数，将/etc/supervisor/目录添加到include中

[include]
files = /etc/supervisor/*.ini

在 /etc/supervisor/ 目录下建立 redis.ini 文件

[program:redis]
command=/data/redis/src/redis-server /data/redis/redis.conf
autorstart=true
autorestart=true
stdout_logfile=/tmp/supervisor.log

2.重启supervisor

[root@kafka60 supervisor]# supervisorctl status
[root@kafka60 supervisor]# supervisorctl reload
Restarted supervisord
[root@kafka60 supervisor]# supervisorctl status
redis                            BACKOFF   Exited too quickly (process log may have details)

3，子进程管理(supervisorctl)

1) 查看所有子进程的状态： 

# supervisorctl status
blog                             RUNNING    pid 2395, uptime 0:08:41
zhoujy                           RUNNING    pid 2396, uptime 0:08:41

2）关闭、开启指定的子进程：

# supervisorctl stop Redis
zhoujy: stopped

# supervisorctl start Redis
zhoujy: started

3）关闭、开启所有的子进程：

# supervisorctl stop all
blog: stopped
zhoujy: stopped
# supervisorctl start all
blog: started
zhoujy: started

4）：其他参数：supervisor开启后子进程自动开启（autostart=true）和子进程退出后自动启动（autorestart=ture）
