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.
安装
既然是perl语言开发的工具集,那当然是先安装perl相关依赖包了
yum install -y perl perl-IO-Socket-SSL perl-DBD-MySQL perl-Time-HiRes perl-Digest-MD5
然后,就到下面这个连接下载最新版的吧,暂时都是linux版本,没有windows的
https://www.percona.com/downloads/percona-toolkit/
或者在linux系统下下载安装:
#先下载Percona Toolkit工具编译包 wget "https://www.percona.com/downloads/percona-toolkit/2.2.20/tarball/percona-toolkit-2.2.20.tar.gz" #解压 tar xf percona-toolkit-2.2.20.tar.gz #进入目录安装 cd percona-toolkit-2.2.20.tar.gz #开始编译安装 perl Makefile.PL make make install #安装完了就有命令了 ll /usr/local/bin/pt-* -r-xr-xr-x 1 root root 41480 Jan 19 11:03 /usr/local/bin/pt-align -r-xr-xr-x 1 root root 263438 Jan 19 11:03 /usr/local/bin/pt-archiver -r-xr-xr-x 1 root root 168985 Jan 19 11:03 /usr/local/bin/pt-config-diff -r-xr-xr-x 1 root root 166210 Jan 19 11:03 /usr/local/bin/pt-deadlock-logger -r-xr-xr-x 1 root root 164927 Jan 19 11:03 /usr/local/bin/pt-diskstats -r-xr-xr-x 1 root root 168895 Jan 19 11:03 /usr/local/bin/pt-duplicate-key-checker -r-xr-xr-x 1 root root 49890 Jan 19 11:03 /usr/local/bin/pt-fifo-split -r-xr-xr-x 1 root root 149727 Jan 19 11:03 /usr/local/bin/pt-find -r-xr-xr-x 1 root root 67037 Jan 19 11:03 /usr/local/bin/pt-fingerprint -r-xr-xr-x 1 root root 133187 Jan 19 11:03 /usr/local/bin/pt-fk-error-logger -r-xr-xr-x 1 root root 218381 Jan 19 11:03 /usr/local/bin/pt-heartbeat -r-xr-xr-x 1 root root 226009 Jan 19 11:03 /usr/local/bin/pt-index-usage -r-xr-xr-x 1 root root 32345 Jan 19 11:03 /usr/local/bin/pt-ioprofile -r-xr-xr-x 1 root root 250059 Jan 19 11:03 /usr/local/bin/pt-kill -r-xr-xr-x 1 root root 21753 Jan 19 11:03 /usr/local/bin/pt-mext -r-xr-xr-x 1 root root 102147 Jan 19 11:03 /usr/local/bin/pt-mysql-summary -r-xr-xr-x 1 root root 393892 Jan 19 11:03 /usr/local/bin/pt-online-schema-change -r-xr-xr-x 1 root root 24594 Jan 19 11:03 /usr/local/bin/pt-pmp -r-xr-xr-x 1 root root 520502 Jan 19 11:03 /usr/local/bin/pt-query-digest -r-xr-xr-x 1 root root 75713 Jan 19 11:03 /usr/local/bin/pt-show-grants -r-xr-xr-x 1 root root 37724 Jan 19 11:03 /usr/local/bin/pt-sift -r-xr-xr-x 1 root root 145553 Jan 19 11:03 /usr/local/bin/pt-slave-delay -r-xr-xr-x 1 root root 128910 Jan 19 11:03 /usr/local/bin/pt-slave-find -r-xr-xr-x 1 root root 181316 Jan 19 11:03 /usr/local/bin/pt-slave-restart -r-xr-xr-x 1 root root 69580 Jan 19 11:03 /usr/local/bin/pt-stalk -r-xr-xr-x 1 root root 90418 Jan 19 11:03 /usr/local/bin/pt-summary -r-xr-xr-x 1 root root 422772 Jan 19 11:03 /usr/local/bin/pt-table-checksum -r-xr-xr-x 1 root root 398202 Jan 19 11:03 /usr/local/bin/pt-table-sync -r-xr-xr-x 1 root root 246864 Jan 19 11:03 /usr/local/bin/pt-table-usage -r-xr-xr-x 1 root root 330806 Jan 19 11:03 /usr/local/bin/pt-upgrade -r-xr-xr-x 1 root root 177020 Jan 19 11:03 /usr/local/bin/pt-variable-advisor -r-xr-xr-x 1 root root 102278 Jan 19 11:03 /usr/local/bin/pt-visual-explain
这样就算安装完毕了,很简单.
随便搞个简单的来测试下.
