supervisord安装使用

supervisord简介:

supervisord是一个c/s模式的进程管理程序，它可以用来监控应用程序的进程，并且可以管理应用程序的start/stop/restart/reload等功能。

安装supervisord:

[email protected]:~# apt-get install supervisord -y #apt安装supervisord
[email protected]:~# supervisord -v #supervisord版本
3.3.1

supervisord配置文件:

supervisord配置文件默认路径:/etc/supervisor/supervisord.conf
[email protected]:~# vim /etc/supervisor/supervisord.conf

; supervisor config file

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

; 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 = /etc/supervisor/conf.d/*.conf   #进程监控配置路径

[inet_http_server]     #web页面端口
port=*:9080            #web页面地址:9080或*:9080
username=admin         #web页面的用户名和密码
password=admin

supervisord监控进程配置文件:

#配置监控的应用程序:
[email protected]:~# vim /etc/supervisor/conf.d/prometheus.conf
#用户程序为prometheus
[program:prometheus]
#启动命令,不能使用nohup等后台运行命令否则应用程序会无限重启
command=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml
autostart=true  #自动启动
autorestart=true  #自动重启
process_name=prometheus  #进程名称
startretries=5  #尝试启动的次数

启动supervisord程序:

[email protected]:~# systemctl start supervisor.service #

打开http://IP:9080,输入用户名和密码就可以在web页面查看监控的应用程序:

supervisordctl命令行

命令	参数	作用
supervisorctl	stop program:name	停止配置文件中的某个应用程序
supervisorctl	start program:name	启动配置文件中的某个应用程序
supervisorctl	restart program:name	重启配置文件中的某个应用程序
supervisorctl	stop all	停止全部进程
supervisorctl	relod	载入新配置文件然后启动应用程序
supervisorctl	update	载入新配置文件启动，没有改变就不重启进程
supervisorctl	tail program:name	查看应用程序的日志
