Apache Log Segmentation (Rotatelogs, Cronolog)

Why do you want to split the log?

With the increase of website access, the log files generated by the Web server will become larger, if not split management, a single log file will become unusually large, not conducive to the comprehensive analysis of the log, monitoring and so on. In addition, when the server encountered a failure, operation and maintenance personnel will open the log file for analysis, the process will inevitably consume a long time, will inevitably increase the time to deal with the failure. Therefore, managing a large amount of log files is of great significance to the management of the website.

Here are two common ways to log segmentation: one. Apache Rotatelogs split Tool 1. Query the absolute path of the Rotatelogs command

which rotatelogs

2. Edit the httpd.conf configuration file

vim /etc/httpd/conf/httpd.conf

Modify the configuration file, mainly the Customlog parameter

<virtualhost *:80>
ServerAdmin [email protected]
DocumentRoot "/usr/local/apache/htdocs"
ServerName www.test.com
Errorlog "|/usr/sbin/rotatelogs-l/usr/local/apache/logs/www.test.com-error%y%m%d.log"
Customlog "|/usr/sbin/rotatelogs-l/usr/local/apache/logs/www.test.com-access%y%m%d.log 86400" combined// Defines the access log format, where 86400 means one day, a new log file is generated daily
</VirtualHost>

Note: Rotatelogs-l uses local time instead of GMT as the time datum, and using-l in an environment that alters the GMT offset (such as daylight saving times) can cause unpredictable results.

3. Create a log file directory

mkdir -p /usr/local/apache/logs

4. Create a Web Site Directory

mkdir -p /usr/local/apache/htdocs

5. Restart the APAHCE service

service httpd stop      //停止service httpd start     //开启

6. Testing

Two. Third-party tools Cronolog log split 1. Unzip the source package into the/OPT directory

tar xzvf cronolog-1.6.2.tar.gz -C /opt

2. Enter the Cronolog directory

cd /opt/cronolog-1.6.2/

3. Configuration

./configure

4. Compiling and installing

make && make install

5. View the absolute path of the Cronolog command

which cronolog

6. Editing the Apache configuration file

vim /etc/httpd/conf/httpd.conf

Modify the configuration file, mainly the Customlog parameter

<virtualhost *:80>
ServerAdmin [email protected]
DocumentRoot "/usr/local/apache/htdocs"
ServerName www.test.com
Errorlog "|/usr/local/sbin/cronolog/usr/local/apache/logs/www.test.com-error%y%m%d.log"
Customlog "|/usr/local/sbin/cronolog/usr/local/apache/logs/www.test.com-access%Y%m%d.log" combined
</VirtualHost>

7. Restart the HTPPD service

service httpd restart

8. Testing
