安装PERL cpan DBD::mysql错误笔记

开始使用:cpan DBD::mysql 命令来安装该模块
由于是编译的版本的SQL版本，已经在/etc/profile 中修改：export PATH=/usr/local/mysql/bin:$PATH
担心找不到mysql lib文件。

报错如下：
# Tried to use 'DBD::mysql'.
# Error: Can't load '/root/.cpan/build/DBD-mysql-4.022/blib/arch/auto/DBD/mysql/mysql.so' for module DBD::mysql: libmysqlclient.so.16: 无法打开共享对象文件: 没有那个文件或目录 at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm line 230.

make: *** [test_dynamic] 错误 9
/usr/bin/make test -- NOT OK
Running make install
make test had returned bad status, won't install without force
[root@localhost dbdata_backup]# perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.7602)
ReadLine support available (try 'install Bundle::CPAN')

解决方式：
shell> perl -MCPAN -e shell
cpan> install DBI
cpan> install DBD::mysql 安装成功。

手工安装DBD安装技巧：
注意mysql的环境变量，若没有则用添加/usr/local/mysql/bin到环境变量PATH中
PATH=/usr/local/mysql/bin:$PATH;
export PATH (mysql的安装路径根据实际情况填写)
wget http://cpan.perl.org/modules/by-module/DBI/DBI-1.601.tar.gz
tar -zxvf DBD-mysql-4.006.tar.gz
cd DBD-mysql-4.006
perl Makefile.PL –mysql_config=/usr/local/mysql/bin/mysql_config
make
make test
make install
