Linux下的Cacti网络管理系统--安装常见问题（一）

一.数据库相关的常见问题

1.在安装php时或者Cactid/Spine/Cacti时出现

　　checking for mysql_init in -lmysqlclient_r... no

　　configure: error: MySQL libraries not found

解决办法：由于在编译php时没有加上--with-mysql=/usr/local/mysql 导致无法管理php开发api

2.在做php 连接数据库时出现 not defined mysql_connect()

解决办法：php没有关联php api, 检查php编译时是否加上了--with-mysql=/usr/local/mysql

3.在安装时，加入了--with-mysql=/usr/local/mysql

出现：whith "configure: error: MySQL libraries not found"

解决办法：确定mysql可以正常运行的情况下，不要使用二进制的安装方式，自己手工编译，问题解决，

网上所谓的奖--with-mysql 改为--with-mysql-dir这种是错误，它编译通过的原因是由于，这种配置是错误的，./configure将其忽略了。

二.其他错误

错误一：

11/15/2010 07:34:42 PM - SPINE: Poller[0] FATAL: Unable to read configuration file! (Spine init)

11/15/2010 07:44:43 PM - SPINE: Poller[0] FATAL: MySQL Error:'1146', Message:'Table 'cacti.settings' doesn't exist' (Spine init)

解决：

检查你的spine 配置文件，或重新安装spine

错误二：编辑spine 时错误

checking if UCD-SNMP needs crypto support... no

checking if Net-SNMP needs crypto support... yes

checking for snmp_timeout in -lnetsnmp... no

Cannot find NET-SNMP libraries(snmp)... checking UCD-SNMP

checking for snmp_timeout in -lsnmp... no

configure: error: Cannot find UCD-SNMP libraries(snmp)

解决：

configure 时加上--with-snmp=/usr/local/net-snmp/ 你的net-snmp路径

或不加或加上这个参数--with-static=/usr/local/lib

./configure --with-static=/usr/local/lib

错误三：

/usr/local/spine/spine

SPINE: Version 0.8.7b starting

11/15/2010 05:19:46 PM - SPINE: Poller[0] ERROR: SNMP Library Version Mismatch (5.3.1 vs 5.3.2.2) (Spine parent)

11/15/2010 05:00:01 PM - SPINE: Poller[0] ERROR: SNMP Library Version Mismatch (5.3.1 vs 5.3.2.2) (Spine parent)

此spine 和net-snmp的版本有问题

解决：

先卸载以前安装的net-snmtp 和spine

先安装net-snmp 然后再编译安装spine 此时你可以指定你的net-snmp 也可以不指定，都可以的。

错误四

11/15/2010 05:00:01 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '60' seconds, with a maximum of a '300' second Cron, but 300 seconds have passed since the last poll!

11/15/2010 04:56:00 PM - SYSTEM STATS: Time:59.2263 Method:spine Processes:1 Threads:1 Hosts:2 HostsPerProcess:2 DataSources:21 RRDsProcessed:0

11/15/2010 04:56:00 PM - POLLER: Poller[0] Maximum runtime of 58 seconds exceeded. Exiting.

解决：

因为cron的时间与poller.php的时间差别有关

一般poller.php的跟新时间为60s，所以cron里边也要设置成每分钟跟新一次

如：

*/1 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

错误五

解决：

暂时的

delete from settings where name = 'syslog_last_incoming' ;
