Linux进程监控服务Supervisor快速入门

Linux进程监控服务Supervisor快速入门

官网地址：

准备

1、 系统中需安装Python环境，我本机python为2.6.6
2、 下载安装supervisor所需软件

elementtree
meld3
setuptools
supervisor

安装

以上四个都为python相关插件，分别解压后，进入各自所在目录中，使用python setup.py install命令安装，其安装顺序依次为：

elementtree、meld3、setuptools、supervisor

⚠️在安装setuptools时需要先执行python bootstrap.py，然后执行python setup.py install命令安装

添加配置文件

配置文件 /etc/supervisord.conf 配置内容如下：

[unix_http_server] file = /var/run/supervisor.sock chmod = 0777 chown= root:root [inet_http_server] # Web管理界面设定 port=node03:9001 ;username = admin ;password = yourpassword [supervisorctl] ; 必须和'unix_http_server'里面的设定匹配 serverurl = unix:///var/run/supervisor.sock [supervisord] logfile=/var/log/supervisord/supervisord.log ; (main log file;default $CWD/supervisord.log) logfile_maxbytes=50MB ; (max main logfile bytes b4 rotation;default 50MB) logfile_backups=10 ; (num of main logfile rotation backups;default 10) loglevel=info ; (log level;default info; others: debug,warn,trace) pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid) nodaemon=false ; (start in foreground if true;default false) minfds=1024 ; (min. avail startup file descriptors;default 1024) minprocs=200 ; (min. avail process descriptors;default 200) user=root ; (default is current user, required if root) childlogdir=/var/log/supervisord/ ; ('AUTO' child log dir, default $TEMP) [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface ;管理的单个进程的配置，可以添加多个program [program:cat] command=/bin/cat autostart = true startsecs = 5 user = root redirect_stderr = true ; 对这个program的log的配置，上面的logfile_maxbytes是supervisord本身的log配置 stdout_logfile_maxbytes = 20MB stdoiut_logfile_backups = 20 stdout_logfile = /var/log/supervisord/cat.log 启动服务

方式一：

# supervisord

方式二：

# supervisord -c /path/to/supervisord.conf

方式一启动时会自己寻找/etc/supervisord.conf文件；方式二通过-c参数指定配置文件所在路径
启动后可以通过Web界面查看服务运行情况，服务地址为：node1:9001

管理服务

使用supervisorctl命令进行服务管理操作：

[root@node1 zxm]# supervisorctl chatdemon RUNNING pid 47457, uptime 0:07:38 test RUNNING pid 47456, uptime 0:07:38 supervisor> help default commands (type help <topic>): ===================================== add exit open reload restart start tail avail fg pid remove shutdown status update clear maintail quit reread signal stop version supervisor> status cat RUNNING pid 47555, uptime 0:00:08 chatdemon RUNNING pid 47554, uptime 0:00:08 test RUNNING pid 47553, uptime 0:00:08 [include]标签

可以使用[include]标签来指定应用程序配置文件，例如：

[zxm@node1 supervise-programs]# cat /etc/supervisord.conf ... ... [include] files= /home/zxm/works/supervise-programs/cat.conf

/home/zxm/works/supervise-programs/cat.conf内容如下：

[zxm@node1 supervise-programs]# cat cat.conf [program:cat] command=/bin/cat autostart = true startsecs = 5 user = root redirect_stderr = true ; 对这个program的log的配置，上面的logfile_maxbytes是supervisord本身的log配置 stdout_logfile_maxbytes = 20MB stdoiut_logfile_backups = 20 stdout_logfile = /var/log/supervisord/cat.log
