Tomcat in use will encounter Catalina.out log is too large, the following we use the system (in CentOS as an example) with the logrotate to cut files, to achieve automatic daily log file cutting. logrotate Program Default program will be cut/etc/logrotate.d/the files defined below, the following methods use the root user action, otherwise you will be prompted insufficient permissions. To create a file:

The Logrotate program is a log file management tool. Used to split the log file, delete the old log file, and create a new log file that acts as a "dump". You can save disk space.Logrotate command format:Logrotate [OPTION ...] -D,--debug:debug mode, test the configuration file for errors.-F,--force: Forced dump file.-M,--mail=command: Sends the log to the specified mailbox.-S,--state=statefile: Use the specified state file.-V,--verbose: Displays the d

Logrotate Introductionlog rotation is especially useful for log files with fixed file names, such as MySQL error log, regular query log, slow query log, and so on. Linux system has a very easy to use according to Logratate can achieve automatic rotation, this article describes its principle and usage. Logrotate is the tool for managing log files, in CentOS systems, where commands are located in/usr/sbin/

In many real-world projects, the application will continue to write logs, and if there are no log libraries in the program code that support automatic sharding, such as by filesize or date cutting, the log files will grow to the G level very quickly. Operating large files on a single machine is very inconvenient for subsequent follow-up logs.This article describes how to use the Logrotate tool to slice logs outside the application. 1. What is

Many software comes with cutting logs, such as Tomcat, which can be named by time. Rsyslog can generate files by date, but does not support "% $year%-% $month%-% $day%" These variables to read the file (current version number: rsyslog-8.17.0-1.el6.x86_64).Then, you need to use the log polling logrotate. overview, configuration.Global configuration:/etc/logrotate.confLocal configuration:/etc/logrotate.d/for ease of administration, custom confi

Recently just to rearrange the log server, just need to reconfigure the system logrotate, so simply write some basic configuration parameters of Logrotate, for easy access.Logrotate The main configuration parameter file is/etc/logrotate.conf, and/etc/logrotate.d/directory in the write configuration is for the usual management convenience written inside, it will eventually be/etc/ Logrotate.conf, which is th

Yesterday, the online project we participated in was launched. After reading the log file, we did not split it. Considering that the log file may cause a large number of log files to cause performance degradation, we quickly split the log file. In Linux, there is a logrotate tool that can assist log segmentation. You only need to configure the parameters, which is very convenient. Therefore, you can directly configure this method. I used to split ngi

The previous article has the salt installation process and the Salt module, not clear can go to look, this article mainly realizes nginx+php uses the logrotate to carry on the cutting to the log, then simply uses under the Salt this tool; The architecture is as follows: The following. pp files are under/etc/puppet/modules/logrotate/manifests, as follows Init.pp Class

Label: better embedded operating system space planScenario: in the actual application environment, we need to independently mount the log directory to a partition or a virtual memory disk. If you mount/var/log to the memory virtual disk and the file format is tmpfs, You need to calculate it carefully. After all, memory resources are always limited, not to mention embedded operating systems. Therefore, it is best to allocate proper memory space during mounting. The so-called fit should be the max

delaycompress option indicates * logrotate do not compress the most recent archive, and compression will take place in the next round-robin cycle.

There are many log files on the Linux system, syslog message mail cron and so on, and application logs and access logs, which, under a lot of accesses, can grow rapidly, consume lots of private disk space and consume Io, The Access_log and catalina.out files of Nginx and Tomcat are now split by crontab using shell scripts on the wire.Today accidentally think of logrotate, small tried, or good, record ...Looking at the logs under the log directory, you
