pt(Percona Toolkit)工具安装

一．pt(Percona Toolkit)工具是由Percona公司开发的一个用perl语言编写的工具集,包含很多功能,例如在线更改数据表结构,校验主从数据,检查数据库状态,分析慢查询等这些靠人手做起来比较麻烦的事情,功能强大,操作简单

二.安装依赖包

yuminstall-yperlperl-IO-Socket-SSLperl-DBD-MySQLperl-Time-HiResperl-Digest-MD5perl-ExtUtils-MakeMaker

下载PerconaToolkit工具编译包

[root@node1 ~]# wget "https://www.percona.com/downloads/percona-toolkit/3.0.3/binary/tarball/percona-toolkit-3.0.3_x86_64.tar.gz"

解压

[root@node1 ~]# tar xf percona-toolkit-3.0.3_x86_64.tar.gz

进入目录安装

[root@node1 ~]# cd percona-toolkit-3.0.3

开始编译安装

[root@node1 percona-toolkit-3.0.3]# perl Makefile.PL

[root@node1 percona-toolkit-3.0.3]# make

[root@node1 percona-toolkit-3.0.3]# make install

就显示出一些常用的pt命令

[root@node1 ~]# ll /usr/local/bin/pt-*

这样就算安装完毕了,很简单.

搞个测试，MySQL服务状态显示：

[root@node1 ~]# pt-mysql-summary --user=root --password='abc123'

mysql: [Warning] Using a password on the command line interface can be insecure.
