supervisor


1. 安装

#python2版本
pip2 install supervisor

#python3  supervisor4版本
pip3 install git+https://github.com/Supervisor/supervisor@master 

2. 配置

mkdir /etc/supervisor
echo_supervisord_conf > /etc/supervisor/supervisord.conf

3. 配置模板说明

[unix_http_server]
file=/tmp/supervisor.sock   ;UNIX socket 文件,supervisorctl 会使用
;chmod=0700                 ;socket文件的mode,默认是0700
;chown=nobody:nogroup       ;socket文件的owner,格式:uid:gid
;[inet_http_server]         ;HTTP服务器,提供web管理界面
;port=127.0.0.1:9001        ;Web管理后台运行的IP和端口,如果开放到公网,需要注意安全性
;username=user              ;登录管理后台的用户名
;password=123               ;登录管理后台的密码
[supervisord]
logfile=/tmp/supervisord.log ;日志文件,默认是 $CWD/supervisord.log
logfile_maxbytes=50MB        ;日志文件大小,超出会rotate,默认 50MB,如果设成0,表示不限制大小
logfile_backups=10           ;日志文件保留备份数量默认10,设为0表示不备份
loglevel=info                ;日志级别,默认info,其它: debug,warn,trace
pidfile=/tmp/supervisord.pid ;pid 文件
nodaemon=false               ;是否在前台启动,默认是false,即以 daemon 的方式启动
minfds=1024                  ;可以打开的文件描述符的最小值,默认 1024
minprocs=200                 ;可以打开的进程数的最小值,默认 200
[supervisorctl]
serverurl=unix:///tmp/supervisor.sock ;通过UNIX socket连接supervisord,路径与unix_http_server部分的file一致
;serverurl=http://127.0.0.1:9001 ; 通过HTTP的方式连接supervisord
; [program:xx]是被管理的进程配置参数,xx是进程的名称
[program:xx]
command=/opt/apache-tomcat-8.0.35/bin/catalina.sh run  ; 程序启动命令
autostart=true       ; 在supervisord启动的时候也自动启动
startsecs=10         ; 启动10秒后没有异常退出,就表示进程正常启动了,默认为1秒
autorestart=true     ; 程序退出后自动重启,可选值:[unexpected,true,false],默认为unexpected,表示进程意外杀死后才重启
startretries=3       ; 启动失败自动重试次数,默认是3
user=tomcat          ; 用哪个用户启动进程,默认是root
priority=999         ; 进程启动优先级,默认999,值小的优先启动
redirect_stderr=true ; 把stderr重定向到stdout,默认false
stdout_logfile_maxbytes=20MB  ; stdout 日志文件大小,默认50MB
stdout_logfile_backups = 20   ; stdout 日志文件备份数,默认是10
; stdout 日志文件,需要注意当指定目录不存在时无法正常启动,所以需要手动创建目录(supervisord 会自动创建日志文件)
stdout_logfile=/opt/apache-tomcat-8.0.35/logs/catalina.out
stopasgroup=false     ;默认为false,进程被杀死时,是否向这个进程组发送stop信号,包括子进程
killasgroup=false     ;默认为false,向进程组发送kill信号,包括子进程
;包含其它配置文件
[include]
files = relative/directory/*.ini    ;可以指定一个或多个以.ini结束的配置文件

4. 服务方式启动
