常识

Supervisor(http://supervisord.org/)是用Python开发的一个client/server服务,是Linux/Unix系统下的一个进程管理工具,不支持Windows系统。它可以很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程,当一个进程意外被杀死,supervisort监听到进程死后,会自动将它重新拉起,很方便的做到进程自动恢复的功能,不再需要自己写shell脚本来控制

 php-worker]# cat supervisord.conf
[supervisord]
logfile=/tmp/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes=50MB        ; max main logfile bytes b4 rotation; default 50MB
logfile_backups=10           ; # of main logfile backups; 0 means none, default 10
loglevel=debug               ; log level; default info; others: debug,warn,trace
pidfile=/tmp/supervisord.pid ; supervisord pidfile; default supervisord.pid22
nodaemon=true
user=www-data
[supervisorctl]
[inet_http_server]
port = *:9001
#username="yourusername"
#password="yourpass"
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

以tomcat 举例


Tomcat进程的一个例子:

[program:tomcat]
command=/opt/apache-tomcat-8.0.35/bin/catalina.sh run
stdout_logfile=/opt/apache-tomcat-8.0.35/logs/catalina.out
autostart=true
autorestart=true
startsecs=5
priority=1
stopasgroup=true
killasgroup=true


bash终端

supervisorctl status
supervisorctl stop tomcat
supervisorctl start tomcat
supervisorctl restart tomcat
supervisorctl reread
supervisorctl update


开机启动Supervisor服务
7.1 配置systemctl服务

1> 进入/lib/systemd/system目录,并创建supervisor.service文件

[Unit]
Description=supervisor
After=network.target

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl $OPTIONS reload
KillMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

2> 设置开机启动

systemctl enable supervisor.service
systemctl daemon-reload

3、修改文件权限为766

chmod 766 supervisor.service
