1. 从这个链接https://www.percona.com/doc/percona-toolkit/3.0/index.html下载percona-toolkit安装包
2. 下载完成通过ftp工具上传到指定目录执行tar 命令解压 解压完成进入解压后的目录执行命令 perl Makefile.PL
执行该命令的时候可能会报这样的错误:
Can't locate ExtUtils/MakeMaker.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 Makefile.PL line 1.
BEGIN failed--compilation aborted at Makefile.PL line 1.
解决方法:yum install perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker cpan
3. 安装完成后 再次执行perl Makefile.PL
4. 然后执行make && make install 进行编译安装,然而当使用pt-duplicate-key-checker --help 查看命令的常用参数时 报错:
Can't locate Digest/MD5.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 /usr/local/bin/pt-duplicate-key-checker line 4371.
BEGIN failed--compilation aborted at /usr/local/bin/pt-duplicate-key-checker line 4371.
解决方法: yum -y install perl-Digest-MD5
5. 到此就可以使用pt 相关的命令了
