Will see how to configure/ use logrotate in Linux
to compress, move, delete or mail log files at the periodic time. By doing this will keep away the filesystem from the filesystem full issue.
Setting up and Manage logrotate in Linux:
In Linux/ Unix, environment /var/log is most important directory and it keeps all the activities as a log.
System administrators will use the logs to analyze any issue’s.
/var/log keeps lots of log files and here is the list.
[root@localhost ~]# ls /var/log anaconda boot.log cron dmesg.old lastlog messages rhsm spooler tuned wtmp audit btmp dmesg firewalld maillog ppp secure tallylog vmware-vmsvc.log
Installing logrotate:
Here I am going to use the yum package manager to install the logrotate.
[root@localhost ~]# yum install logrotate Loaded plugins: product-id, search-disabled-repos, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. Package logrotate-3.8.6-12.el7.x86_64 already installed and latest version Nothing to do
look likes the package is already installed on my machine.
/etc/logrotate.conf is an important configuration file which contains all the configuration of log rotation and “include /etc/logrotate.d ” this line should be uncommented.
We have plenty of option in logrotate and below is that.
Will create /etc/logrotate.d/apache2.conf file and insert below content.
/var/log/apache/* {
weekly
rotate 5
size 25M
compress
delaycompress
}
Daily, Weekly, Monthly: Based on this input the tool will rotate the logs.
rotate 5: This will keep the only 5 files and the old files will be removed.
size 25: log file minimum size for log rotation.
Compress & Delaycompress: These are used to say that all are already rotated logs.
Now will do s test using the below command
[root@localhost ~]# logrotate -d /etc/logrotate.d/apache2.conf
