CentOS 4.6 で、ZABBIX 1.4.4

社内のサーバ監視に、ZABBIX（日本語サイト）を使用しているのですが、ZABBIX 1.4 では、「WEB monitoring」というWebサイトを簡単に監視できる機能が搭載されたようなので、この機能を使いたいがため、1.1.3 からアップデートしてみました。

CentOS 4.6 の環境で、いくつか躓いたところがあったので、メモです。

CURLのバージョン

Web Monitoring機能を有効にするには、--with-libcurlオプションを付けてインストールします。

$ ./configure --enable-server --with-mysql --with-net-snmp --with-libcurl

すると、次のようなエラーが出て止まってしまいます。

checking for libcurl >= version 7.13.1... no
configure: error: Not found Curl library

CentOS 4.x では、curlのバージョンは7.12なのでダメなようです。

いろいろ調べてみると、結局、curlを自身でバージョンアップするしかないようです。

以下のようにして解決です。

centosinstall

$ cd ~/src/
$ wget ftp://ftp.planetmirror.com/pub/curl/libcurl4-devel-7.16.2-1.i386.rpm
$ wget ftp://ftp.planetmirror.com/pub/curl/libcurl4-7.16.2-1.i386.rpm
$ sudo yum install openssl096b
$ sudo yum remove curl-devel
$ sudo rpm -i libcurl4* 

PHP4

ZABBIXのフロントエンドはPHPなのですが、やっとインストールが成功して管理画面にアクセスすると以下のエラーが発生。

PHP Parse error: parse error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /u02/zabbix/web/include/copt.lib.php on line 112

調べてみると、PHP5用のコードになっているのが原因のようです。

以下のようにして解決です。

Blank web install - ZABBIX Forums

includes/copt.inc.php を修正し、'static function' を 'function' にすべて置き換えます。

$ vi includes/copt.inc.php
:%s/static function/function/g

これで、無事にアップデートすることができました。
