No longer worry about log files too large: mooon-server Common Log Scrolling script

log_rotater.sh

#!/bin/sh

# writed by Yijian on 2012/7/22

# This script feature:

# 1 Implementation of a common log scrolling by size

# 2 requires a log file extension of ". Log", otherwise please modify the code slightly

# 3 supports the processing of log files in multiple directories, and if this function is required,

# You must enable the Dirs_list parameter

#

# Why do you write such a thing?

# A: Because in daily life, the program output redirection is often found,

# or the output of the script, if not handled, can cause

# A single file is too large to even fill up the entire disk, and each set of scripts

# Write a log scrolling logic repeatedly, it's obviously boring,

# Even some people do not bother to do processing, a long time, you will find a huge

# log file, this script hopefully can help solve this problem so that everyone has no

Worries

#

# Use Method:

# 1 Copy the script to the directory where the log files are located,

# then start the script in Nohup/log_rotater.sh >/dev/null &, and so on.

# 2 In addition to the above method, can also be log_rotater.sh any directory,

# But this time, you should change the value of Backup_dir to the directory where the log files are located

#

# sudo dpkg-reconfigure Dash

# New version Ubuntu defaults to using the dash as the shell,

# This shell is weak, does not support arrays, and so on, but fast,

# The following methods can be used to detect what Shell is:

# ls-l ' which sh '

# to modify the following parameters as needed

Number of backup_count=10 # log scrolling

backup_size=$ ((1024 * 1024 * 200)) # Single log file size

BACKUP_INTERVAL=60 # detection interval, in seconds

# If the file specified by dirs_list exists, read the directory from dirs_list.

# Otherwise, only the single directory specified by Backup_dir is processed

# When you specify a file or add or subtract directory to dirs_list, you do not need to restart log_rotater.sh

Backup_dir=. # directory where log files are located

Dirs_list=./dirs.list # Stores directory listing files, requiring one row of directories

# process log scrolling under a single directory
