Centos+Xampp+Cacti安装注意事项

1、安装LAMPP注意版本及操作系统如果是centos需要修改如下：


vi /opt/lampp/lampp

osguess() {
 if test -f /etc/redhat-release
 then
  if egrep "9 " /etc/redhat-release > /dev/null
  then
   echo "rh9"
   return 0
  else

修改成：   

osguess() {
 if test -f /etc/redhat-release
 then
  if egrep "Red" /etc/redhat-release > /dev/null
  then
   echo "rh9"
   return 0
  else
          echo "linux"
   return 0
  fi
 elif test "$(uname)" = "Darwin"
 then
  echo "macosx"
  return 0


2、如果LAMPP需要使用其它端启动如：81端口
修改成： 修改成： 修改成： vi /opt/lampp/lampp
   vi /opt/lampp/lampp  

 if testport 81
 then
  $GETTEXT -s "fail."
  echo "XAMPP: " $($GETTEXT 'Another web server is already running.')
  return 1
 fi

3、修改httpd.conf配置
# vi /opt/lampp/etc/httpd.conf
Listen 81

4、注意CACTI服务器时间及物理时间是否同步，设定时区
# vi  d
/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "123456";
$database_port = "3308";
$database_ssl = false;
date_default_timezone_set('Asia/shanghai');

5、设置定时捕捉数据，注意建议不要修改捕捉数据时间：
# crontab -l# crontab -e

*/5  * * * *  /opt/lampp/bin/php /opt/lampp/htdocs/cacti/poller.php > /dev/null 2>&1
 
6、安 装net-snmp
#yum install net-snmp
7 、修改snmpd.conf文件
#       sec.name  source          community
#com2sec notConfigUser  default       public
com2sec notConfigUser  172.40.8.117       public

####
# Finally, grant the group read-only access to the systemview view.

#       group          context sec.model sec.level prefix read   write  notif
access  notConfigGroup ""      any       noauth    exact  all none none
