今天打算用MySQL自带的基准测试套件(Benchmark Suite)来测试一下插入性能,结果出现错误:
# 还是交代一下环境吧
[root@beanvm ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.2 (Santiago)
[root@beanvm ~]# uname -a
Linux beanvm 2.6.32-220.el6.i686 #1 SMP Wed Nov 9 08:02:18 EST 2011 i686 i686 i386 GNU/Linux
# 下为报错
[mysql@beanvm ~]$ cd /usr/local/mysql/sql-bench/
[mysql@beanvm sql-bench]$ ./test-insert --server=mysql --user=root --password=mysql --log
Can't locate DBI.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at ./test-insert line 33.
BEGIN failed--compilation aborted at ./test-insert line 33.
很显然这里缺少DBI组件,它是perl连接数据库的重要接口,先来检查一下这个包是否存在
[mysql@beanvm ]$ rpm -qa |grep perl-DB
可以直接用yum来安装,这里我用的安装包的形式,幸运的是,这些包在RHEL6的安装介质中都可以找到,只要安装下面两个包就可以了:
[root@beanvm Packages]# rpm -ivh perl-DBI-1.609-4.el6.i686.rpm

error: Failed dependencies:

libmysqlclient.so.16(libmysqlclient_16) is needed by perl-DBD-MySQL-4.013-3.el6.i686
在安装perl-DBD-MySQL包时,我们发现提示缺失libmysqlclient.so.16文件,如果是经常安装MySQL的话,应该知道libmysqlclient.so是一个MySQL数据库中必备的库文件,会不会是没有链接到呢?
[root@beanvm ~]# ls -l /usr/lib/libmysqlclient.so.16*

从上面的结果可以得知,已经存在libmysqlclient.so.18文件了,但是版本不符,因此还是需要这个libmysqlclient.so.16文件,那么从哪里可以找到呢?最简便的方法就是安装MySQL RPM安装套件中的MySQL-shared-compat包:(我的MySQL是编译安装的,但是在同版本的RPM套件中MySQL-shared-compat-5.6.16-1.el6.i686.rpm包却提供了必要的libmysqlclient.so.16文件,就这点来说编译部署还是没有RPM安装来的全面)
# 我的MySQL版本:5.6.16
[root@beanvm ~]# rpm -ivh MySQL-shared-compat-5.6.16-1.el6.i686.rpm
Preparing... ########################################### [100%]
1:MySQL-shared-compat ########################################### [100%]
再次安装perl-DBD-MySQL-4.013-3.el6.i686.rpm就可以了
[root@beanvm Packages]# rpm -ivh perl-DBD-MySQL-4.013-3.el6.i686.rpm
warning: perl-DBD-MySQL-4.013-3.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

1:perl-DBD-MySQL ########################################### [100%]
综上所述,安装DBI建议顺序安装三个包:
# DBI安装包:
perl-DBI-1.609-4.el6.i686.rpm
# 必备的库文件包,注意版本,这里主要提供的是libmysqlclient.so.16
MySQL-shared-compat-5.6.16-1.el6.i686.rpm
# DBD组件
perl-DBD-MySQL-4.013-3.el6.i686.rpm
成功后就可以使用Benchmark进行基准测试了,下面是测试插入性能的部分数据:
[mysql@beanvm sql-bench]$ ./test-insert --server=mysql --user=root --password=mysql --log
