一.部署LAMP平台(略)

二.安装软件包：

#yum install libdbi* libnet
#cpan Date::Calc Text::LevenshteinXS String::CRC32
#cpan -i Digest::SHA1
#cpan -i Net::MySQL


三、下载相关包

#cd /home/install
#mkdir logzilla;cd logzilla
#wget http://www.balabit.com/downloads/files/eventlog/0.2/eventlog_0.2.9.tar.gz
#wget http://www.balabit.com/downloads/files/syslog-ng/open-source-edition/3.0.3/setups/rhel-5-i386/syslog-ng-3.0.3-1.rhel5.i386.rpm (或者 syslog-ng-2.1.4-9.el5.x86_64)
#wget http://lwlp.googlecode.com/files/logzilla_v2.9.9o.tgz

四、开始安装

# cp eventlog_0.2.9.tar.gz /usr/src/redhat/SOURCES/
# tar zxvf  eventlog_0.2.9.tar.gz
# cd eventlog-0.2.9/
# cp ../eventlog_0.2.9.tar.gz /usr/src/redhat/SOURCES/eventlog_0.2.9.tar.gz
# rpmbuild --ba eventlog.spec.bb
# cd /usr/src/redhat/RPMS/x86_64
# rpm -Uvh libevtlog*

#cd /home/install/logzilla
#rpm -Uvh syslog-ng-3.0.3-1.rhel5.i386.rpm



五、安装logzilla

#cd /www/webroot/
#wget http://php-syslog-ng.googlecode.com/files/logzilla_v2.9.9o.tgz (http://blog.liuts.com/post/209/)
#tar xzvf logzilla_v2.9.9o.tgz
#mkdir -p /var/log/logzilla


六、配置Mysql

# mysql -u -p
mysql> SELECT @@event_scheduler;
+-------------------+
| @@event_scheduler |
+-------------------+
| OFF               |
+-------------------+
1 row in set (0.00 sec)



低于Mysql5.1版本会提示如下，如不打算升级到logzilla3.0，没有关系，可以略过此步骤。
mysql> SELECT @@event_scheduler;
ERROR 1193 (HY000): Unknown system variable 'event_scheduler'

激活event_scheduler

mysql> SET GLOBAL event_scheduler = 1;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @@event_scheduler;
+-------------------+
| @@event_scheduler |
+-------------------+
| ON                |
+-------------------+
1 row in set (0.00 sec)

mysql> quit;


七、修改Syslog-ng配置
#vi /opt/syslog-ng/etc/syslog-ng.conf
@version: 3.0
source s_local {  
internal();  
unix-stream("/dev/log");  
file("/proc/kmsg" program_override("kernel: "));  
};  
source s_local {  
        udp(ip(0.0.0.0) port(514));  
};  

# destinations  
destination d_messages { file("/var/log/client.logs"); };  

options {  
long_hostnames(off);  
# doesn't actually help on Solaris, log(3) truncates at 1024 chars  
log_msg_size(8192);  
# buffer just a little for performance  
# sync(1); <- Deprecated - use flush_lines() instead  
flush_lines(1);  
# memory is cheap, buffer messages unable to write (like to loghost)  
log_fifo_size(16384);  
# Hosts we don't want syslog from
#bad_hostname("^(ctld.|cmd|tmd|last)$");
# The time to wait before a dead connection is reestablished (seconds)
time_reopen(10);
#Use DNS so that our good names are used, not hostnames
use_dns(yes);
dns_cache(yes);
#Use the whole DNS name
use_fqdn(yes);
keep_hostname(yes);
chain_hostnames(no);
#Read permission for everyone
perm(0644);
# The default action of syslog-ng 1.6.0 is to log a STATS line
# to the file every 10 minutes.  That's pretty ugly after a while.  
# Change it to every 12 hours so you get a nice daily update of  
# # how many messages syslog-ng missed (0).  
# stats(43200);  
};  
destination d_logzilla {  
program("/opt/web/phplog/php-syslog-ng/scripts/db_insert.pl"  
template("$HOST\t$FACILITY\t$PRIORITY\t$LEVEL\t$TAG\t$YEAR-$MONTH-$DAY\t$HOUR:$MIN:$SEC\t$PROGRAM\t$MSG\n")  
template_escape(yes)  
);  
};  
# Tell syslog-ng to log to our new destination  
log {  
source(s_local);  
destination(d_logzilla);  
};

八、修改apache配置
#vi httpd.conf
view plainprint?

   <VirtualHost *:80>  
       ServerAdmin liutiansi@gmail.com  
       DocumentRoot /www/webroot/php-syslog-ng/html/  
       ServerName syslog.com.cn  
       ErrorLog logs/syslog.com.cn-error_log  
       CustomLog logs/syslog.com.cn-access_log common  
   # LogZilla  
   Alias /logs "/www/webroot/php-syslog-ng/html/"  
   <Directory "/www/webroot/php-syslog-ng/html/">  
       Options Indexes MultiViews FollowSymLinks  
       AllowOverride All  
           Order allow,deny  
           Allow from all  
   </Directory>  
   </VirtualHost>  


重启apache服务：/etc/init.d/apache2 restart

九、修改php.ini
Vi /usr/local/php/lib/php.ini

  1. memory_limit = 128M  
  2. max_execution_time = 300  
  3. /etc/init.d/apache2 restart  


十、配置日志分隔
cp /www/webroot/php-syslog-ng/scripts/contrib/system_configs/logrotate.d /etc/logrotate.d/logzilla

十一、添加作业

@daily /usr/local/php/bin/php /www/webroot/php-syslog-ng/scripts/logrotate.php >> /var/log/php-syslog-ng/logrotate.log
@daily /usr/bin/find /www/webroot/php-syslog-ng/html/jpcache/ -atime 1 -exec rm -f '{}' ';'
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/php/bin/php /www/webroot/php-syslog-ng/scripts/reloadcache.php >> /var/log/php-syslog-ng/reloadcache.log

注意：新的版本安装需要清空：/opt/web/phplog/html/config/config.php
