安裝 Cacti 0.8.8h + RRDtool 1.5.6 (目前最新版本 1.6.0 )
在 Cacti 管理畫面
==> System Utilities / Technical Support 畫面中，出現的警告訊息：
ERROR: Installed RRDTool version does not match configured version.
Please visit the Configuration Settings and select the correct RRDTool Utility Version.
原因
Cacti 裡頭部份程式沒正確更新
包括兩個程式：
utilities.php
include/global_arrays.php
解決
原 Cacti 中的 utilities.php 只支援 RRDtool 1.x ~ 1.4
但 include/global_arrays.php 中卻有出現 1.5 的選項
所以修改 utilities.php 程式：
if (preg_match("/^RRDtool 1\.4/", $out_array[0])) {
$rrdtool_version = "rrd-1.4.x";
}else if (preg_match("/^RRDtool 1\.3\./", $out_array[0])) {
$rrdtool_version = "rrd-1.3.x";
}else if (preg_match("/^RRDtool 1\.2\./", $out_array[0])) {
$rrdtool_version = "rrd-1.2.x";
}else if (preg_match("/^RRDtool 1\.0\./", $out_array[0])) {
$rrdtool_version = "rrd-1.0.x";
}
改為
if (preg_match("/^RRDtool 1\.6/", $out_array[0])) {
$rrdtool_version = "rrd-1.6.x";
} elseif (preg_match("/^RRDtool 1\.5/", $out_array[0])) {
$rrdtool_version = "rrd-1.5.x";
} elseif (preg_match("/^RRDtool 1\.4/", $out_array[0])) {
$rrdtool_version = "rrd-1.4.x";
}else if (preg_match("/^RRDtool 1\.3\./", $out_array[0])) {
$rrdtool_version = "rrd-1.3.x";
}else if (preg_match("/^RRDtool 1\.2\./", $out_array[0])) {
$rrdtool_version = "rrd-1.2.x";
}else if (preg_match("/^RRDtool 1\.0\./", $out_array[0])) {
$rrdtool_version = "rrd-1.0.x";
}
include/global_arrays.php
$rrdtool_versions = array(
"rrd-1.0.x" => "RRDTool 1.0.x",
"rrd-1.2.x" => "RRDTool 1.2.x",
"rrd-1.3.x" => "RRDTool 1.3.x",
"rrd-1.4.x" => "RRDTool 1.4.x",
"rrd-1.5.x" => "RRDTool 1.5.x" );
$rrdtool_versions = array(
"rrd-1.0.x" => "RRDTool 1.0.x",
"rrd-1.2.x" => "RRDTool 1.2.x",
"rrd-1.3.x" => "RRDTool 1.3.x",
"rrd-1.4.x" => "RRDTool 1.4.x",
"rrd-1.5.x" => "RRDTool 1.5.x",
"rrd-1.6.x" => "RRDTool 1.6.x"
);
完成
