mytop-MySQL监控工具

1、OS版本：Red Hat Enterprise Linux Server release 5.3
MySQL版本：4.0.26
2、安装文件列表：
MySQL-shared-compat-5.1.57-1.rhel5.i386.rpm
mytop-1.6.tar.gz
perl-DBD-MySQL-3.0007-2.el5.i386.rpm
perl-DBI-1.52-2.el5.i386.rpm
TermReadKey-2.30.tar.gz
3、相关文件下载链接：
wget http://search.cpan.org/CPAN/authors/id/J/JS/JSTOWE/TermReadKey-2.30.tar.gz
wget http://jeremy.zawodny.com/mysql/mytop/mytop-1.6.tar.gz
wget ftp://mirror.switch.ch/pool/1/mirror/mysql/Downloads/MySQL-5.1/MySQL-shared-compat-5.1.57-1.rhel5.i386.rpm
wget ftp://ftp.icm.edu.pl/vol/rzm2/linux-slc/slc54/i386/SL/perl-DBD-MySQL-3.0007-2.el5.i386.rpm
wget ftp://ftp.icm.edu.pl/vol/rzm2/linux-slc/slc58/i386/SL/perl-DBI-1.52-2.el5.i386.rpm
4、安装流程如下：
[root@tech tmp]# tar zxvf TermReadKey-2.30.tar.gz && cd TermReadKey-2.30
[root@tech TermReadKey-2.30]# perl Makefile.PL && make && make install
[root@tech TermReadKey-2.30]# cd ..
[root@tech tmp]# rpm -Uvh MySQL-shared-compat-5.1.57-1.rhel5.i386.rpm perl-DBD-MySQL-3.0007-2.el5.i386.rpm perl-DBI-1.52-2.el5.i386.rpm
[root@tech tmp]# tar zxvf mytop-1.6.tar.gz && cd mytop-1.6
[root@tech mytop-1.6]# perl Makefile.PL && make && make install
5、配置mytop并运行
[root@tech mytop-1.6]# mytop
Cannot connect to MySQL server. Please check the:

  * database you specified "test" (default is "test")
  * username you specified "root" (default is "root")
  * password you specified "" (default is "")
  * hostname you specified "localhost" (default is "localhost")
  * port you specified "3306" (default is 3306)
  * socket you specified "" (default is "")

The options my be specified on the command-line or in a ~/.mytop
config file. See the manual (perldoc mytop) for details.

Here's the exact error from DBI. It might help you debug:

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@tech mytop-1.6]# cat << EOF >/root/.mytop
> user=root
> pass=123456
> host=127.0.0.1
> db=cacti
> delay=10
> port=3306
> resolve=0
> socket=/tmp/mysql.sock
> EOF
[root@tech mytop-1.6]# mytop
6、更详细的参数选项请参考man手册，这里不再赘述。
[root@tech mytop-1.6]# man mytop
7、以下是我的安装和配置过程:

8、总结：将以上安装过程写成脚本进行快速安装，由于IDC做了ACL限制，不能直接进行wget对安装文件进行下载，个人是首先将安装文件下载到个人电脑，然后上传到服务器的，以下是脚本示例，
[root@tech ~]# cat mytop_install.sh
_DIR=/tmp/wyq
cd ${_DIR}
tar zxvf TermReadKey-2.30.tar.gz && cd TermReadKey-2.30
perl Makefile.PL && make && make install
cd ..
rpm -Uvh MySQL-shared-compat-5.1.57-1.rhel5.i386.rpm perl-DBD-MySQL-3.0007-2.el5.i386.rpm perl-DBI-1.52-2.el5.i386.rpm
tar zxvf mytop-1.6.tar.gz && cd mytop-1.6
perl Makefile.PL && make && make install
cd ..
rm -rf TermReadKey-2.30 mytop-1.6
cat << EOF >/root/.mytop
user=root
pass=123456
host=127.0.0.1
db=cacti
delay=10
port=3306
resolve=0
socket=/tmp/mysql.sock
EOF
9、提示：请根据自己的实际环境修改mytop的配置文件以及安装脚本

注：2012年06月18号增加安装效果图，如下
