CentOS 7.6上部署Supervisor来监控和操作各类服务

yum install epel-release
yum install -y supervisor

supervisord -c /etc/supervisord.conf

[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9001        ; (ip_address:port specifier, *:port for all iface)
username=user              ; (default is no username (open server))
password=123               ; (default is no password (open server))

[program:mypro]
command =uwsgi /usr/local/bin/uwsgi --ini /root/js_back/js_back_uwsgi.ini ; 启动命令, 可以看出与手动在命令行启动的命令是一样的
autostart = false     ; 在 supervisord 启动的时候也自动启动
stopsignal=QUIT    
user=root
startsecs = 5     ; 启动 5 秒后没有异常退出，就当作已经正常启动了
startretries = 3   ; 启动失败自动重试次数，默认是 3
autorestart = true   ; 程序异常退出后自动重启
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 = /root/js_back_uwsgi.log
stderr_logfile = /root/js_back_err.log

[uwsgi]

chdir           = /root/js_back
module          = js_back.wsgi
master          = true
processes       = 3
socket            = 0.0.0.0:8001
vacuum          = true
pythonpath      = /usr/bin/python3
pidfile = /root/js_back/js_back.pid
# 注释掉 daemonize 模式，因为 Supervisor 无法控制守护进程服务 
#daemonize  = /root/js_back/uwsgi.log
