问题

我想要用mysql的一个工具

[root@localhost bin]# ./mysqlhotcopy
Can't locate Data/Dumper.pm 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 ./mysqlhotcopy line 22.
BEGIN failed--compilation aborted at ./mysqlhotcopy line 22.

google的结果是下载一个软件

yum是从固定配置好的”软件仓库reposity“下载软件

wget是从具体某个网址下载软件，详细参考官网：GUN wget

第一反应是用yum来下载wget这个工具

yum install wget

接着用wget下载需要的工具

[root@localhost bin]# wget http://www.cpan.org/modules/by-module/Data/Data-Dumper-2.121.tar.gz
--2016-01-07 17:05:06--  http://www.cpan.org/modules/by-module/Data/Data-Dumper-2.121.tar.gz

2016-01-07 17:05:09 ERROR 404: Not Found.

发现没有找到想要的 ”Data-Dumper-2.121.tar.gz",亲自上去 “http://www.cpan.org/modules/by-module/Data/” 看看

原来名字已经更换了，重新下载就好了

[root@localhost bin]# wget http://www.cpan.org/modules/by-module/Data/Data-Dumper-2.154.tar.gz

下载的目录就是现在的目录

迁移到“默认的软件安装目录”

mv Data-Dumper-2.154.tar.gz /usr/local

把压缩包解开

tar xzvf Data-Dumper-2.154.tar.gz

接着开始编译安装了

[root@localhost Data-Dumper-2.154]#

报出一个新的错误，google查了一下，原因是缺乏perl-devel 这个软件

顺利成章的安装一下，安装的过程中，有很多的依赖包自动处理了，难以想象如果一个一个手动安装的话得多累

再来一次编译

[root@localhost Data-Dumper-2.154]# perl Makefile.PL
Checking if your kit is complete...
Looks good
Warning: prerequisite Test::More 0.98 not found.
Writing Makefile for Data::Dumper

接下来是

make
make install

大概就安装完了

重新调用  mysqlhotcopy

[root@localhost bin]# ./mysqlhotcopy
Can't locate DBI.pm 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 ./mysqlhotcopy line 25.
BEGIN failed--compilation aborted at ./mysqlhotcopy line 25.

再次google一下，需要安装两个软件

perl-DBD-mysql

perl-DBI

如果要使用Yum的方式安装这两个包的话，就需要配置一个“拥有这两个软件”的软件仓库，详细参考：Yum install perl-DBD-mysql, perl-DBI to use "mysqlreport" under CentOS 5.2 + DirectAdmin

vi /etc/yum.repos.d/dag.repo[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

配置完以后就可以yum了

yum install perl-DBD-mysql perl-DBI

安装完以后，mysqlhotcopy可以使用了

[root@localhost bin]# ./mysqlhotcopy
Database name to hotcopy not specified
./mysqlhotcopy Ver 1.23Usage: ./mysqlhotcopy db_name[./table_regex/] [new_db_name | directory]-?, --help           display this help-screen and exit-u, --user=#         user for database login if not current user-p, --password=#     password to use when connecting to server (if not setin my.cnf, which is recommended)-h, --host=#         hostname for local server when connecting over TCP/IP-P, --port=#         port to use when connecting to local server with TCP/IP-S, --socket=#       socket to use when connecting to local server--old_server     connect to old MySQL-server (before v5.5) whichdoesn't have FLUSH TABLES WITH READ LOCK fully implemented.--allowold           don't abort if target dir already exists (rename it _old)--addtodest          don't rename target dir if it exists, just add files to it--keepold            don't delete previous (now renamed) target when done--noindices          don't include full index files in copy--method=#           method for copy (only "cp" currently supported)

看起来是可以使用了，但当真正要备份数据库时，还是出现一个错误

[root@localhost bin]# ./mysqlhotcopy mysql /windows10/000000000000000/
install_driver(mysql) failed: Can't load '/usr/lib64/perl5/vendor_perl/auto/DBD/mysql/mysql.so' for module DBD::mysql: libmysqlclient.so.18: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 190.at (eval 11) line 3.
Compilation failed in require at (eval 11) line 3.

这里有安装手册：http://cpansearch.perl.org/src/JWIED/DBD-mysql-2.1017/INSTALL.html#name

未完待续。。。。。
