supervisord管理mysql_supervisord 管理非daemon启动方式软件

1.安装 supervisord

pip install supervisor

如果提示pip 不存在情况

wget https://bootstrap.pypa.io/get-pip.py

python get-pip.py

2.配置supervisord 以及启动

mkdir -p /data/etc/supervisor/confs

cd /data/etc/supervisor/

在此配置supersord.conf 文件用来启动supervisord控制程序。

cat /data/etc/supervisor/supervisord.conf

[unix_http_server]

file = /var/run/supervisord.sock

chmod = 0777

chown= root:root ; 设置sock用户 如果想普通用户能访问则需要设置为普通用户

[inet_http_server]

port=127.0.0.1:9001

[supervisorctl]

serverurl = unix:///var/run/supervisord.sock

[supervisord]

logfile = /data/logs/supervisor/supervisord.log ;supervisord 运行日志

logfile_maxbytes = 50MB

logfile_backups = 20

loglevel = info

pidfile = /tmp/supervisor.pid

nodaemon = false

minfds = 1024

minprocs = 200

user = root ;启动supervisord 用户

childlogdir = /data/logs/supervisor/ ;设置主日志文件位置

[rpcinterface:supervisor]

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[include]

files = /data/etc/supervisor/confs/*.conf ;读取用户配置文件位置

到此supervisord主程序配置完成( 启动前删除 # 和中文说明)。使用

supervisord -c /data/etc/supervisor/supervisord.conf

命令就可以启动supervisord

3.添加非 daemon程序

进入 supervisord.conf 中配置的 files 目录 /dada/etc/supervisor/confs

cd /data/etc/supervisor/confs

cat first.conf

[program:tg_robot]

environment=PYTHONPATH=”/data/app/tg_robot/src:$PYTHONPATH”

directory=/data/app/tg_robot/src/

command=/home/yunsm/.local/bin/gunicorn -c gunicorn_app.py app:app

autostart=true ; start at supervisord start (default: true)

autorestart=true ; retstart at unexpected quit (default: true)

startsecs=10 ; number of secs prog must stay running (def. 10)

startretries=3 ; max # of serial start failures (default 3)

user=yunsm ; setuid to this UNIX account to run the program

redirect_stderr=true

stdout_logfile=/data/logs/supervisor/tg_robot.log ; child log path, use NONE for none; default AUTO

stdout_logfile_maxbytes=20MB ; max # logfile bytes b4 rotation (default 50MB)

stdout_logfile_backups=20 ; # of logfile backups (default 10)

stopasgroup=true

killasgroup=true

还有一些类似mysql的特殊程序，supervisor 只能管关闭supervisor启动的子进程，类似mysql这样自己启动的子进程的程序就需要使用上 pidproxy 和pid文件文件了。下面举个mysql启动的例子

[program:mysql]

command=/usr/local/python27/bin/pidproxy /usr/local/mysql/var/localhost.localdomain.pid /usr/local/mysql/bin/mysqld_safe –datadir=/usr/local/mysql/var

autostart=true ; start at supervisord start (default: true)

autorestart=true ; retstart at unexpected quit (default: true)

startsecs=10 ; number of secs prog must stay running (def. 10)

startretries=3 ; max # of serial start failures (default 3)

user=root ; setuid to this UNIX account to run the program

redirect_stderr=true

stdout_logfile=/data/logs/supervisor/mysql.log ; child log path, use NONE for none; default AUTO

stdout_logfile_maxbytes=20MB ; max # logfile bytes b4 rotation (default 50MB)

stdout_logfile_backups=20 ; # of logfile backups (default 10)

stopasgroup=true

killasgroup=true

配置好了需要启动的进程之后，可以使用以下命令

supervisorctl update 加载supervisord 子程序

supervisorctl start mysql 使用supervisord 启动mysql

supervisorctl status 查看supervisord 启动程序状态

supervisorctl stop mysql 停止mysql
