Logrotate's log rotation Linux

Case: Logrotate's log rotation

For admin.log files, set logrotate

Rotate once a day

Keep 3 Backups

File larger than 100k Auto rotate

On the finished file compression Create permission 0600, owner Root belongs to group root

Steps:

1. First check if the Logrotate package is installed

[Email protected] log]# rpm-q logrotate

Logrotate-3.7.8-17.el6.x86_64

Create log Admin.log because I don't have admin.log this file in my virtual machine

[Email protected] log]# Mkair Admin.log

2. Setting up the configuration file

[Email protected] log]# vim/etc/logrotate.d/admin

/var/log/admin.log {

Missingok

Daily

Size 100k

Rotate 3

Create 0600 root root

Compress

3. Testing

Here because the log is more than 100K automatic rotation, we can manually rotate

Find a file larger than 100k in the system file and copy it to Admin.log

[Email protected] log]# Cp/etc/ssh/moduli/var/log/admin.log

[Email protected] log]# logrotate/etc/logrotate.conf

[Email protected] log]# ls-l/var/log/admin.log*

-RW-------. 1 root root 125811 February 16:10/var/log/admin.log

-RW-------. 1 root root 127214 February 15:59 /var/log/admin.log-20170228.gz

can look at a. GZ end of the compressed file, indicating that the rotation log file settings are successful

You can also force rotation through the logrotate-f command. But it doesn't make much sense, because it doesn't make sense to detect whether our settings are successful, regardless of whether the set conditions will be rotated.
