Install syslog-ng management logs

Syslog-ng is installed to manage server logs in a unified manner. The installation method is found online. Some problems need to be solved now;

1. The log server can synchronize the log files on a daily basis, but the log files you want cannot be synchronized to the server because you need to customize the log files. Now, I have posted the configuration documents and hope to learn from them.

Install syslog-ng

Service installation:

Yum install GCC *

CD/usr/src

Wget http://www.balabit.com/downloads/files/syslog-ng/sources/3.2.4/source/eventlog_0.2.12.tar.gz

Wget http://www.balabit.com/downloads/files/syslog-ng/open-source-edition/3.3.5/source/syslog-ng_3.3.5.tar.gz

Tar xvf eventlog_0.2.12.tar.gz

CD eventlog-0.2.12

./Configure -- prefix =/usr/local/EventLog

Make

Make install

CD/usr/src

Tar xvf syslog-ng_3.3.5.tar.gz

CD syslog-ng-3.3.5

Export pkg_config_path =/usr/local/EventLog/lib/pkgconfig

./Configure -- prefix =/usr/local/syslog-ng

Make

Make install

Add syslog-ng as a system service,

Note: If you want to add a new monitoring service log, you need to add a few places: the configuration file marked as red

Add to client

Local4. */var/log/usercmd. Log

#/Usr/local/syslog-ng/sbin/syslog-ng-e-f-D-V

Test whether the syslog-ng configuration file is correct.

On the client side, we use the rsyslog system's built-in log collection service.

VI/etc/rsyslog. conf

Add a row at the bottom

*. Info @ 10.0.11.53

VI/etc/syslog. conf

Add as follows:

*. Info; mail. None; news. None; authpriv. None; cron. None @ service IP
