mysql的监控工具mysqlreport安装和说明
mysqlreport以很友好的方式显示 mysql状态变。事实上，它几乎报告了所有的状态。不像 show status 只是在显示了100多个状态值，mysqlreport 则以人性化的方式阐释和格式化了这些状态值，大大增加了其可读性。
mysqlreport 的好处是可以快速的查看各种状态参数组，从而了解服务器的运行状态情况，而无需从 show status的结果中人工计算。例如索引读取比率是个重要的参数，但是 show status 中并没有显示；它是一个推断值(key_reads 和 key_read_requests 的比值)。
mysql命令行中精彩使用下面的指令来获取当前数据库的实时状态
mysql>show status;
mysql>show innodb status;但是他们的显示结果不太友好，我们需要更好的更加人性化的分析结果，而不是堆出来一堆数字。mysqlreport是一个第三方的Mysql状态报告工具，它把mysql的show status 和 show innodb status的结果进行一系列的后期处理，让可读性更强，更友好
mysqlreport 是用perl语言编写，所以想要运行它首先需要安装perl环境；它还要与mysql数据库连接，所以还需要安装数据库接口 DBI 和 数据库驱动 DBD-MySQL 。
一、安装perl环境
[root@linux-node2 ~]# yum -y install perl perl-devel
[root@linux-node2 ~]# perl -v #如果显示perl版本说明perl环境已经安装
二、安装DBI
[root@linux-node2 ~]# cd /usr/local/src/
[root@linux-node2 src]# wget https://cpan.metacpan.org/authors/id/T/TI/TIMB/DBI-1.636.tar.gz
[root@linux-node2 src]# tar zxvf DBI-1.636.tar.gz
[root@linux-node2 src]# cd DBI-1.636
[root@linux-node2 DBI-1.636]# perl Makefile.PL
[root@linux-node2 DBI-1.636]# make
[root@linux-node2 DBI-1.636]# make install
三、安装DBD-mysql
[root@linux-node2 ~]# cd /usr/local/src/
[root@linux-node2 src]# wget http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.020.tar.gz
[root@linux-node2 src]# tar zxvf DBD-mysql-4.020.tar.gz
[root@linux-node2 src]# cd DBD-mysql-4.020
[root@linux-node2 DBD-mysql-4.020]# perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config
[root@linux-node2 DBD-mysql-4.020]# make
[root@linux-node2 DBD-mysql-4.020]# make install
备注：
1、现在最新版本的DBD-mysql是4.042，下载地址：
http://www.cpan.org/authors/id/M/MI/MICHIELB/DBD-mysql-4.042.tar.gz
2、如果有报错，内容为
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/Arch')" t/*.t t/00base....................ok 1/6

cp /usr/local/mysql/lib/mysql/* /usr/lib
cp /usr/local/mysql/lib/mysql/* /usr/lib64/ (如果64位 否则是lib)三、安装mysqlreport
建议直接用yum安装
[root@linux-node2 ~]# yum -y install mysqlreport四、myslreport用法
1、帮助信息和选项
[root@linux-node2 ~]# mysqlreport --help
2、输出信息
[root@linux-node2 ~]# mysqlreport --user root --password 123456 -h 192.168.88.134 --no-mycnf --flush-status --outfile ~/123MySQL 5.6.35 uptime 0 0:58:2 Fri Jun 9 23:19:01 2017
