centos安装supervisor守护进程与简单配置使用

首先确定你的yum仓库有supervisor的包:

yum list | grep supervisor

如果没有先加入repo源。

centos6:

wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

rpm -ivh epel-release-6-8.noarch.rpm

centos7:

wget https://mirrors.tuna.tsinghua.edu.cn/epel/epel-release-latest-7.noarch.rpm

rpm -ivh epel-release-latest-7.noarch.rpm

之后再运行

yum install supervisor

安装结束会有一个默认的配置文件在 /etc/supservisord.conf

; The below sample group section shows all possible group values, 
; create one or more 'real' group: sections to create "heterogeneous" 
; process groups. 
;[group:thegroupname] 
;programs=progname1,progname2 ; each refers to 'x' in [program:x] definitions 
;priority=999 ; the relative start priority (default 999)

; The [include] section can just contain the "files" setting. This 
; setting can list multiple files (separated by whitespace or 
; newlines). It can also contain wildcards. The filenames are 
; interpreted as relative to this file. Included files *cannot* 
; include files themselves. 
[include] 
files = supervisord.d/*.ini

其中已经有各个设置选项的默认配置: 
1. unix_http_server 通讯端口约定 
2. supservisord 主服务进程配置，需要此服务启动才能正常使用 
3. rpcinterface rpc接口 
4. supervisorctl 客户端配置，用来调度各个被守护的进程 
5. program:example 监听的进程配置 
6. eventlistener 事件监听 
7. group 组 
8. include 所加载的配置文件

一般按照默认配置即可使用，不建议在主配置里写其他进程，注意最后的include，会调用/etc/supervisord.d/*.ini文件。举例:

vi /etc/supervisord.d/example.ini

[program:swoole] 
command=php /home/swoole.php //运行的命令 
autostart=true //自动开启 
autorestart=true //自动重启 
user=root //用户 
numprocs=3 //进程数 
stdout_logfile=/var/log/supervisor-swoole.log //日志路径

使用

supervisorctl reread

重新加载配置，之后守护开始运行

如果有其他问题，可以使用命令重新运行所守护的进程

supervisorctl reload
