Linux logs: Rsyslog and Loganalyzer (ii)

Last Post we analyzed the basic knowledge and configuration of Rsyslog, following we continue to improve the next blog post, the final use of Rsyslog+loganalyzer+mysql deployment log server, to achieve the WebGui display of log information.

"Experimental Environment and Topology"

System: CentOS 6.5

RSYSLOG:RSYSLOGD 5.8.10

loganalyzer:loganalyzer-3.6.5

lamp:httpd-2.4.4,mysql-5.6.10,php-5.4.13

"Experimental Configuration"

1) Build lamp platform, initialize installation Loganalyzer;

In the previous log we have installed MySQL, so we do not repeat, now we only need to install httpd and PHP, here only for the demo configuration Log server effect, so with the Yum way to install, in the actual production environment, we can compile the installation according to need.

☆11, Ok!host host (ip:192.168.0.112) logs are all on the log server can be viewed, is not very convenient it;

"Supplemental Note: Statistics cannot display graphics solutions"

The normal display is as follows:

Error one: Due to incorrect time zone settings in PHP;

Error two: GD and PHP-GD These two packages are not installed can also lead to errors, the solution is simple yum install-y gd PHP-GD installed on these two packages can!

It's all right! A simple log server is deployed, the specific use of our own according to the actual production needs to improve the research, I just finished the basic configuration, if there is nothing to summarize the place, but also asked Heroes to shoot bricks!
