Supervisor的安装与使用入门
CentOS 之 Supervisor
本文档针对CentOS,也是我搭环境记录的笔记,其他系统可以参考最下面的参考资料。
安装supervisor
1 | yum install supervisor |
生成配置文件
Creating a Configuration File
Once the Supervisor installation has completed, run echo_supervisord_conf
. This will print a “sample” Supervisor configuration file to your terminal’s stdout.
Once you see the file echoed to your terminal, reinvoke the command as echo_supervisord_conf > /etc/supervisord.conf
. This won’t work if you do not have root access.
If you don’t have root access, or you’d rather not put the supervisord.conf file in /etc/supervisord.conf`, you can place it in the current directory (echo_supervisord_conf > supervisord.conf) and start supervisord with the -c flag in order to specify the configuration file location.
For example, supervisord -c supervisord.conf. Using the -c flag actually is redundant in this case, because supervisord searches the current directory for a supervisord.conf before it searches any other locations for the file, but it will work. See Running Supervisor for more information about the -c flag.
Once you have a configuration file on your filesystem, you can begin modifying it to your liking.
打开supervisor的配置文件
1 | vi /etc/supervisord.conf |
将supervisord的配置文件拷贝到/home/supervisord/目录下,这是我的习惯,将配置文件集中管理
先创建目录
1 | mkdir /home/supervisord/ |
然后拷贝文件过去
1 | cp /etc/supervisord.conf /home/supervisord/supervisord.conf |
编辑配置文件
1 | vi /home/supervisord/supervisord.conf |
在/home/supervisord/supervisord.conf最后追加如下内容,这个例子是配置shadowsocks
1 | [program:shadowsocks] |
最后,启动
1 | supervisord -c /home/supervisord/supervisord.conf |
如果想要supervisord开机自启动
编辑启动文件
1 | vi /etc/rc.local |
在新行添加要执行的命令
1 | supervisord -c /home/supervisord/supervisord.conf |
常用命令
查看所有action
1 | supervisorctl help |
控制所有进程
1 | supervisorctl start all |
控制目标进程
1 | supervisorctl stop shadowsocks |
备用教程
Supervisor是一个进程管理工具,官方的说法
用途就是有一个进程需要每时每刻不断的跑,但是这个进程又有可能由于各种原因有可能中断。当进程中断的时候我希望能自动重新启动它,此时,我就需要使用到了Supervisor
这个工具主要就两个命令:
supervisord : supervisor的服务器端部分,启动supervisor就是运行这个命令
supervisorctl:启动supervisor的命令行窗口。
安装(Centos):
1 | yum install python-setuptools |
如果easy_install不好使就从官方下载:
然后通过python安装:
1 | tar zxf supervisor-3.1.3.tar.gz |
成功安装后可以登陆python控制台输入import supervisor 查看是否能成功加载。
生成配置文件(supervisord.conf):
1 | echo_supervisord_conf > /etc/supervisord.conf |
修改配置文件:
(更多配置说明请参考:http://supervisord.org/configuration.html)
运行命令:
1 | supervisord -c /etc/supervisord.conf //启动supervisor |
1 | supervisorctl //打开命令行 |
另外有一个坑需要注意:如果修改了 /etc/supervisord.conf ,需要执行 supervisorctl reload 来重新加载配置文件,否则不会生效。。
