rsyslog + MySQL + LogAnalyzer on OpenSUSE
1. Install requirements
|
1 |
zypper install rsyslog rsyslog-module-relp rsyslog-module-mysql rsyslog-module-snmp rsyslog-module-mmnormalize |
2. Create RuleBase for PHP log
|
1 2 3 4 5 |
vi /etc/rsyslog.d/phplog.rulebase # PHP Logs rule=: %server:char-to:\x3a%\x3a PHP %priority:char-to:\x3a%\x3a%message:rest% rule=: PHP %priority:char-to:\x3a%\x3a%message:rest% |
3. Prepare MySQL
