安装

pip install keepstart

示例配置

application:
    daemon: true
    workspace: /opt/ssh-proxy-server
    pidfile: ssh-proxy-server.pid

keepstart:
    nic: lo
    vip: 127.0.0.1
    start: /opt/ssh-proxy-server/start.sh
    stop: /opt/ssh-proxy-server/stop.sh

logging:
    version: 1
    disable_existing_loggers: false
    formatters:
        simple:
            format: "%(asctime)-15s\t%(levelname)s\t%(message)s"
    handlers:
        console:

配置以使用分离的logging.conf

1. 配置yaml

application:
    daemon: true
    workspace: /opt/ssh-proxy-server
    pidfile: ssh-proxy-server.pid

keepstart:
    nic: lo
    vip: 127.0.0.1
    start: /opt/ssh-proxy-server/start.sh
    stop: /opt/ssh-proxy-server/stop.sh
    is-running: /opt/ssh-proxy-server/is-running.sh
    sleep: 2
    running-report-cycle: 3600
    force-test-cycle: 60

logging: logging.conf

将logging设置为config.yaml中的配置文件，并创建logging.conf文件。

1. logging.conf

[loggers]
keys=root,keepserver,appserver

[handlers]
keys=consoleHandler,fileHandler

[formatters]
keys=simpleFormatter

[logger_root]
level=DEBUG
handlers=consoleHandler,fileHandler

[logger_keepserver]
level=DEBUG
handlers=consoleHandler,fileHandler
qualname=keepserver
propagate=0

[logger_appserver]
level=DEBUG
handlers=consoleHandler,fileHandler
qualname=appserver
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=DEBUG
formatter=simpleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=logging.handlers.TimedRotatingFileHandler
level=DEBUG
formatter=simpleFormatter
args=('logFile.log', 'D', 1, 30, 'utf-8')

[formatter_simpleFormatter]
format=%(asctime)s %(levelname)5s %(message)s

您必须添加logger_xxx，其中xxx是要激活以进行日志记录的模块。
