#uzip php-weathermap-0.97a.zip
#mv weathermap /usr/local/wwwroot/cacti/plugins/
#chown -R apache.apache/usr/local/wwwroot/cacti/plugins/weathermap
对weathermap的配置文件进行修改
#cd /usr/local/wwwroot/cacti/plugins/weathermap
#chmod u+w config/
#cp editor-conifg.php-dist editor-config.php#vieditor-config.php
$cacti_base = "/usr/local/wwwroot/cacti";
$cacti_url = "http://222.186.43.15/cacti";
$mapdir= $cacti_base .' /plugins/weathermap/configs';
$ignore_cacti = FALSE;

#vi editor.php
//$ENABLED=false;将false修改为true
$ENABLED=true；
点击console ->PluginManagement->在Actions处启用weathermap，至此weathermap插件安装完成。
syslog插件的安装
1.安装syslog-ng服务
#rpm -ivh syslog-ng-2.1.4-1.el5.i386.rpm
2.安装syslog插件
#tar zxvf syslog-0.5.2.tar.gz
#mv syslog /usr/local/wwwroot/cacti/plugins/
点击console ->PluginManagement->在Actions处启用syslog
进入"User Management"->点admin->RealmPermissions->勾选View Syslog和
Configure Syslog Alerts / Reports
#m ysql -uroot -p
mysql>create databasesyslog; 创建一个数据库供syslog使用mysql>usesyslog;
mysql>source/usr/local/wwwroot/cacti/plugins/syslog/syslog.sql导入mysql数据库mysql>grant all onsyslog.* to cacti@localhost identified by 'cacti';添加一个数据库账号cacti密码为cacti用以访问syslog库mysql>flushprivileges;
#cd /usr/local/wwwroot/cacti/plugins/syslog
#vi config.php
$syslogdb_type = 'mysql';
$syslogdb_default = 'syslog';
$syslogdb_hostname = 'localhost';
$syslogdb_username = 'cacti';
$syslogdb_password = 'cacti';
#vi /etc/syslog-ng/syslog-ng.conf 在最后末尾添加如下：
source net {
udp();
};
destination d_mysql {
pipe("/tmp/mysql.pipe"
template("INSERT INTO syslog_incoming (host, facility, priority,date, time, message) VALUES ( '$HOST', '$FACILITY', '$PRIORITY','$YEAR-$MONTH-$DAY', '$HOUR:$MIN:$SEC', '$MSG' );n")
template-escape(yes)
);
};
log { source(net); destination(d_mysql); };
log { source(s_sys); destination(d_mysql);};
完成之后，执行
#service syslog restart
#service syslog-ng restart
在syslog插件目录下，编辑一个新的sh文件/plugins/syslog/syslog2mysql.sh，并且赋予可执行权限（同时该目录下
syslog_process.php也必须有可执行权限）：
#vi/usr/local/wwwroot/cacti/plugins/syslog/syslog2mysql.sh输入
#!/bin/bash
if [ ! -e /tmp/mysql.pipe ]
then
mkfifo /tmp/mysql.pipe
fi
while [ -e /tmp/mysql.pipe ]
do mysql -u root syslog < /tmp/mysql.pipe>/dev/null
done
运行syslog2mysql.sh，如果没有任何显示，后台有该进程，则基本上成功了。在/etc/crontab中添加：
@reboot /usr/local/wwwroot/cacti/plugins/syslog2mysql.sh
*/1 * * * * php/usr/local/wwwroot/cacti/plugins/syslog_process.php
使开机执行syslog2mysql.sh，每分钟执行一次syslog_process.php
