配置Mailgraph_ext，使用Extman的图形日志

32121fff

客上进行测试的。1，安装依赖包
# yum install cairo-devel libxml2-devel pango-devel libpng-devel freetype-devel libart_lgpl-devel perl-File-Tail


2，安装Time::HiRes
# tar xf Time-HiRes-1.9732.tar.gz
# cd Time-HiRes-1.9732
# perl Makefile.PL
# make
# make test
# make install

3，安装rrdtool-1.4.0.tar.gz  （http://oss.oetiker.ch/rrdtool/pub/?M=D）
# tar xf rrdtool-1.4.0.tar.gz
# cd rrdtool-1.4.0
# ./configure --prefix=/usr/local/rrdtool
# make
# make install


4，创建必要的符号链接(Extman会到这些路径下找相关的库文件)
# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/auto/RRDs/RRDs.so  /usr/lib64/perl5/5.10.0/x86_64-linux-thread-multi
# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/RRDs.pm
/usr/lib64/perl5/5.10.0/x86_64-linux-thread-multi/
# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/auto/RRDs/RRDs.so  /var/www/extsuite/extman/libs



5，复制mailgraph_ext到/usr/local，并启动之
# cp -r /var/www/extsuite/extman/addon/mailgraph_ext  /usr/local  
# /usr/local/mailgraph_ext/mailgraph-init start


6，启动 mailgraph-init 错误：

Starting mail statistics grapher: mailgraph_ext
Can't locate loadable object for module RRDs in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/mailgraph_ext/mailgraph_ext.pl line 292

==============================================================
解决方法：
a，首先检测RRDs 模块是否安装
# perl -MRRDs -le 'print q(ok!)'

b，再创建链接文件

# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/auto/RRDs/RRDs.so  /usr/lib64/perl5/5.10.0/x86_64-linux-thread-multi

# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/RRDs.pm

/usr/lib64/perl5/5.10.0/x86_64-linux-thread-multi/

# ln -sv /usr/local/rrdtool/lib/perl/5.10.1/x86_64-linux-thread-multi/auto/RRDs/RRDs.so  /var/www/extsuite/extman/libs

c，再次验证
# perl -MRRDs -le 'print q(ok!)'
================================================================

7，启动cmdserver(在后台显示系统信息)
# /var/www/extsuite/extman/daemon/cmdserver --daemon

8，添加到自动启动队列
# echo “/usr/local/mailgraph_ext/mailgraph-init start” >> /etc/rc.d/rc.local
# echo “/var/www/extsuite/extman/daemon/cmdserver -v -d” >> /etc/rc.d/rc.local


9，重新启动httpd
# service httpd restart
# service postfix restart

10，在Extman后台就可以查看图形日志了
