percona-toolkit是一组高级命令行工具的集合，用来执行各种通过手工执行非常复杂和
麻烦的mysql和系统任务，这些任务包括：

  • ü 检查master和slave数据的一致性
  • ü 有效地对记录进行归档
  • ü 查找重复的索引
  • ü 对服务器信息进行汇总
  • ü 分析来自日志和tcpdump的查询
  • ü 当系统出问题的时候收集重要的系统信息
    percona-toolkit源自Maatkit和Aspersa工具，这两个工具是管理mysql的最有名的工具，现在Maatkit工具已经不维护了，请大家还是使用percona-toolkit吧！这些工具主要包括开发、性能、配置、监控、复制、系统、实用六大类，作为一个优秀的DBA，里面有的工具非常有用，如果能掌握并加以灵活应用，将能极大的提高工作效率。

安装mysql

如果没有安装，请看传送门。

如果安装了，服务器启动有问题，请检查配置文件，查看日志。最好的解决方法就是log-error指定的错误日志中记录的信息，或者使用mysqld status命令来查看。

问题解决后，启动的时候可以选择mysqld_safe &，也可以使用mysqld --user=root来启动。最好的方式还是mysqld.server start，但是不一定能成功，错误日志中没有信息，找不出原因。

安装DBD::MySQL

DBD:MySQL是Perl5的MySQL数据库驱动。首先需要安装Perl，macOSX中默认安装了perl，使用命令perl -v可以查看perl的版本，如果没有perl命令，说明可能没有安装perl，需要自己安装perl。

如果安装了perl，接下来安装DBD::MySQL。

1
2
perl -MCPAN -e "install DBD::mysql"

如果之前没有对CPAN做过配置处理，安装时，会在用户名录下创建一个.cpan的文件下，生成一个配置文件*.cpan/CPAN/MyConfig.pm*。关于cpan的具体不谈，我们要做的是安装pt。

安装时，会询问：What approach do you want?让你选择local::lib,选项有sudo和manual。这里我们选择sudo即可。
安装时，其一会做test，其二需要把生成的libmysqlclient.dylib放到mysql安装的路径下的lib下，所以需要先安装mysql。

做测试连接时，默认是从/tmp/mysql.sock中与mysql建立socket连接的，但是mac默认的socket路径是 /var/lib/mysql/mysql.sock，所以，解决方案就是在/tmp/下建立软连接，或者把在/etc/my.cnf中修改socket的路径为/tmp/mysql.sock。

安装DBD::MySQL的时候，建议mysql是正常运行的，这样安装测试时，创建测试账号，执行授权等操作时就可以看出问题。但也可以不启动，最多就是skip过测试。

这时候，DBD::MySQL就安装成功了。

安装percona-toolkit

下载percona-toolkit:

1
wget https://www.percona.com/downloads/percona-toolkit/3.0.1/source/tarball/percona-toolkit-3.0.1.tar.gz

截止写本文时，最新版本是3.0.1，后续如果版本更新了，大家到官网查看，version：percona-toolkit-3.0.1，software:Source Code.选择Source Code即可看到tar.gz文件。点击可以直接下载，复制链接可以使用wget下载。

mac中建议安装软件路径放在/usr/local/Cellar/下面，比如percona-toolkit可以使用这样的路径: /usr/local/Cellar/percona-toolkit/3.0.1/`,不信你自己看看，mac使用brew安装的软件一定是放在Cellar下面，然后软件名，下一层则是版本号。

所以，建议下载好percona-toolkit后，解压(或者解压后移动)到/usr/local/Cellar/percona-toolkit/3.0.1/下面。

# 进入到安装目录
cd /usr/local/Cellar/percona-toolkit/3.0.1/
# perl编译Makefile.PL文件，生成配置Makefile、MYMETA.yml和MYMETA.json文件，下面是输出信息
# Writing Makefile for percona-toolkit
# Writing MYMETA.yml and MYMETA.json
perl ./Makefile.PL 

# make ，执行Makefile文件
make 

# make test
make test

# make install
sudo make install

执行make install时需要sudo的权限。执行之后，会看到安装信息:

安装Term::ReadKey

基本上所有Linux系统的安装文档中都在强调Term::ReadKey，在mac中，似乎不安装这一部分也不会有影响。

需要安装Term::ReadKey 包，否则会报perl(Term::ReadKey)>=2.10 is needed by percona-toolkit-2.1.1-1.noarch错误

如果真的出现如大家所遇到的问题，那么安装就一下也无妨。
在命令窗口输入cpan命令回车，出现cpan的控制台。

1
install Term::ReadKey

这样安装即可,然后再安装percona-toolkit。
